Advantages And Disadvantages Of Nc
The generation of NACs started when it has become the era of BYOD. This has become the reason
for potential network security risk. Through NAC, a device is forced to properly identify itself
before it is given access to the network [2]. With the improvements and innovations with endpoint
network security, some of its current weaknesses are asset management, role–based access, and the
guest network access [4]. NAC is able to integrate endpoint security, network security, and system
authentication compensating for the weaknesses given above.

Developing Mixed Environments Of 802.1x And Non 802.1x...
More commonly, switches from different manufacturers are inconsistent in the way they must be
configured to support 802.1X, particularly in how they handle mixed environments of 802.1X and
non–802.1X endpoints. This and other factors make initial configuration and ongoing management
of 802.1X in wired LANs very resource intensive – and therefore expensive.
Wired LANs also tend to support a greater variety of legacy endpoints, many of which do not
support 802.1X supplicant software. The number of non–802.1X endpoints in wired LANs often
exceeds 802.1X–capable ones. As mentioned above, it is challenging to configure different switches
(particularly in multivendor networks) to handle a mix of both 802.1X and non– 802.1X endpoints.

Examples include devices such as those used for physical security in many facilities, including
surveillance cameras, ID card readers, entry keypads and the like.
Various industries such as manufacturing, retail, healthcare, energy and many others support unique
types of endpoints in their networks for which 802.1X supplicant software is not available. In many
environments, non–802.1X endpoints can far outnumber 802.1X–capable ones.
As a result, a significant challenge for implementing 802.1X in many networks involves what to do
about all the non–802.1X endpoints and how to handle network connectivity for those devices.
There are options and workarounds, but each one involves compromise in terms of network security
and/or management complexity.
[callout box]
» OPTIONS FOR HANDLING NON–802.1X ENDPOINTS
Deny All (not realistic!)
Whitelist All (not secure!)
MAC Authentication Bypass (doable, but manually intensive)
[end of callout box]
One option (though seldom feasible) is to simply deny network access to all non–802.1X endpoints.
For most organizations this is really not an option since many of the non–802.1X endpoints are
critical to business operations. Machines on a manufacturing floor, cash registers in a retail store,
heart monitors and other patient care devices in a hospital all must be allowed on the network. So

Security Architecture Is Developed For Systems Providing...
X.805 security architecture is developed for systems providing end to end communications. It was
developed by ITU–T SG 17 and was published in October 2003.
Issues which X.805 addresses are:
1. What type of protection is to be given against what kind of threats?
2. What are the various kinds of system gear and facility groupings that needs to be secured?
3. What are the different types of network exercises that needs to be secured?
X.805 architecture incorporates three security layers which are as follows:
Infrastructure Security Layer: These are fundamental building pieces of networks services and
applications. Example: routers, switches, servers etc.
Services Security Layer: These are services given to end clients. Example: Cellular, Wi–Fi, QoS etc.
Applications Security Layer: These are network based applications used by end–clients. Example:
E–mail, E–commerce etc.
Security planes speak about the types of activities that occur on a network. X.805 architecture has
three security planes, which are as follows:
End – User Security Plane: This security plane represents the access and use of the network by the
customers for various purposes, like value – added services, basic connectivity/transport etc.
Control/Signaling Security Plane: This security plane represents activities that enable efficient
functioning of the network.
Management Security Plane: This plane represents the management of network elements, services
and applications.

As demand for endpoint security systems grew, network access controls solutions have evolved into
security automation & orchestration. In addition to controlling access, Network Sentry now offers
the unique advantage of 100% endpoint visibility, automated triage, and automated quarantine of
suspicious devices. Our proven solution is helping more than 1,000 organizations, including Atrius
Health, UC Irvine Health and US Health Group. While there are many endpoint security solutions,
there are a number of key features healthcare organizations should require to ensure a strong
security posture and HIPAA compliance. Here is a checklist of important security features:
1) Complete endpoint visibility. Ensure that the solution can see and profile every single endpoint. If
you cannot see an endpoint, you cannot track all the actions. A complete audit trail is critical for
historical forensic evidence and HIPAA compliance. Network Sentry was developed to provide
comprehensive visibility.
2) Enforce minimum security programs and patches for endpoint devices before they connect to the
network. Known security vulnerabilities and patch management are one of the leading causes of
breaches and a big concern for healthcare organizations. We integrated granular control of pre–
connect endpoint device requirements into Network Sentry so organization can select the minimum
security requirements and patch levels for the OS, AV software, and more. Network Sentry

Management Access Control At Lan Essay
Introduction:
Several buildings spread across a local area network with hundreds or thousands of devices ranging
in size from single office computers, a computer network LAN stands for. The main role of LAN

games, file servers, and other services. LAN aspect of the development of the school, the university,
the office building to operate as a small geographic area, quick data transfer.
LAN common share data devices in the world today are major large–sized businesses, and the
interaction between the role and the lower its cost. LAN 's data can be transmitted at rates faster than
the speed of the telephone line, and have the ability to transmit data; But the distances are limited.
Management level in a LAN configuration and the type of equipment involved in the running no
need to manage access to it over the network, and it is important to protect the network from
hacking and virus attack.
Management Access Control at LAN :
Access control to the main function and that is to control the members of the network LAN to use
the data from the area. LAN users do what they can access resources on a system; they specify what
activities it offers management. For example, there are several sections of a company; Marketing, IT
marketing and accounts of the users do not need access to the data by the IT department and so on.

ABSTRACT
Process control vendors are migrating their plant control technologies to more open network and
operating environments such as Unix, Linux, Windows, Ethernet, and the Internet Protocol.
Migrating plant controls to open network and operating environments exposes all layers of the
computing environment to unauthorized access. Layered security can be used to enhance the level of
security for any computing environment. Layered security incorporates multiple security ... Show
Compartmentalization is a technique used to segment network space to better control access and
isolate risk of exposure. A variety of security products can be layered into "compartments" to
address examination, detection, prevention, and encryption requirements.
LAYERED SECURITY MODEL
A layered security model incorporates security products and "best practices" in all layers of a
computing environment. Layered security exponentially increases the cost and difficulty of
penetration for an attacker by combining different security products to create a defensive barrier
much stronger than the individual components. Thus, layered security decreases the likelihood that
the attacker will pursue an organization (2).
Computing environments are comprised of networks, operating systems, applications, and databases
(Figure 1). Information security, as a practice, focuses on securing an organizations most important
asset – its data. When you consider that data is the basic underlying component that organizations
strive to develop, store, and protect, then an organization should implement a security model that
focuses on providing multiple layers of resistance to that data.

There are four basic security functions that should be implemented in a complimentary manner to
secure each layer of a computing environment: examination,

The Vulnerability Of Network Infrastructure Vulnerabilities
Security services are an integral part of any network design. Assessing the vulnerability of network
infrastructure to disruptive events is recognized as an important component of network planning and
analysis. This section provides an overview of common network infrastructure vulnerabilities,
essential network security concepts analysis and present. It illustrates the possible placement of
servers including access paths to the Internet, intrusion detection systems (IDS), and firewalls. This
paper also describes a comprehensive security policy for a company including ethical aspects related
to employee behavior, contractors, password usage, and access to networked resources and
information. Network infrastructure vulnerabilities ... Show more content on Helpwriting.net ...
Networks are typically plagued by three primary vulnerabilities: Technology vulnerabilities,
Configuration vulnerabilities, and Security policy vulnerabilities. Technological vulnerabilities:
Various types of network equipment, such as routers, firewalls, and switches, have security
weaknesses that must be recognized and protected against. These weaknesses include the following:
Password protection, Lack of authentication, Routing protocols, and Firewall holes.
Configuration Weaknesses: Misconfigurations of the equipment itself can cause significant network
equipment security problems. For example, misconfigured access lists, routing protocols, or SNMP
community strings can open up large security holes. Misconfigured or lack of encryption and
remote–access controls can also cause significant security issues, as can the practice of leaving ports
open on a switch (which could allow the introduction of "comparative company" computing
equipment).
Security Measures Security measures are safeguard that addresses a threat and mitigates risk.
Network security means protecting network infrastructure and information systems from
unauthorized access, use, disclosure, disruption, modification, or destruction. Security management
is a process of defining the security controls in order to protect the network infrastructure as well as
information assets. There two general security measures when designing a network infrastructure.

Essay On Firewall Security
FIREWALL SECURITY This reports looks at what a firewall is, and how it works. It also looks at
what security risks can be stopped by a firewall in a computer system. Most people think that a
firewall is where all data traffic on the internet has to go through between networks, as shown in
Figure 1.1 [pic] What is a firewall? In network security, firewall is considered a first line of defense
in protecting private information. "A firewall sits at the junction point, or gateway, between the two
networks, which are often a private network and a public network such as the Internet." (John V.
Harrison, Hal Berghel, 2004, A Protocol Layer Survey of Network Security). It is a system designed
to prevent certain access to or from another ... Show more content on Helpwriting.net ...
The purpose of the firewall is to monitor the connection state. It then decides whether to permit or
deny the data traffic. If the data passed is not matched to the state of conversation, or if the data is
not in the state table, then this data is dropped. This is called 'stateful inspection'. Access
authentication provided by firewalls For authentication, firewalls use different types of mechanisms.
1 – Firewalls use usernames and passwords. When a connection receives authentication and
authorisation once, then the user is not asked this information again. 2 – Certificates and public keys
are also used for authorisation and authentication. 3 – Authentication can be handled through pre
shared keys. These are better than certificates as they are less complex and easier to implement. The
time it takes to authenticate is the same whether it is a certificate or a pre shared key. A pre shared
host is issued with a predetermination key which is used for authentication. There is only one
problem with a pre shared key: that it rarely changes. There are many organisations that use the
same key to manage multiple remote hosts. This could be a security threat for the organisation. If a
host firewall is not successful in its authentication, then the packet will be dropped. Role of a
firewall as intercessor A firewall can act as an intercessor to help with the communication process
between two hosts. This process is known as Proxy and

5. What is a Network Access Control (NAC) System? Explain its benefits in securing access control
to a network.
a) NAC is a networking solution for wired and Wi–Fi connections that identifies potential problems
on a computer before it accesses the network. NAC uses a set of protocols to define and implement
a policy that describes how to secure access to network nodes by devices when they initially attempt
to access the network.
b) A benefit of NAC is the ability to control access to a network access to the LAN without putting
the network in danger. Based on a computer's credentials and the software installed on it, a NAC
system may give it full access to the LAN, deny it any access, or give it partial access.
6. Explain the purpose of a Public Key Infrastructure (PKI) and give an example of how you would
implement it in a large organization whose major concern is the proper distribution of certificates
across many sites.
a) A PKI (public key infrastructure) enables users of a basically unsecure public network such as the
Internet to securely and privately exchange data and money through the use of a public and a private
cryptographic key pair that is obtained and shared through a trusted authority.

Causes And Consequences Of Data Leakage
Data leakage involves loss of data which invariable leads to loss of knowledge. Knowledge is an
important asset for existence as it involves the seamless combination of experiences, specialist
insight, standards and plans (Ahmad, Bosua and Scheepers 2014). Thus data is indispensable for
development, preserve competitive edge and when it is lost can lead to several consequences.
Consequences of data leakage are considerably high since once data is lost it is difficult to regain it
back and consequences can last for a lifetime. Consequences of data leakage can be classified as
direct or indirect loss (Gordon 2007). Direct loss is easy to quantify and measure such as fines (Phua
2009). However indirect loss is almost impossible to measure and have wider implications like
negative publicity (Shabtai, Yuval and Rokach 2012). This will probably lead to loss of revenue and
business edge. Indirect loss is one of the reasons for unreported data leakage incidents (Symantec
2014). In 2012, 72% of organisations that experience major data leakage incident closed within 24
months, 93% file for bankruptcy within one year while 50% closed immediately (Gunnarsson 2014).
Thus the consequences of data leakage have serious implications as discussed in sub–section 1.6.
1.6 IMPLICATION OF DATA LOSS Implication of data leakage is varied as data have different
meaning to different entities. The use of computer systems to store clients' sensitive data has raised
concern due to

Q: X.805 security architecture, how it compares with the X.800 network security access architecture
A: X.805 architecture was developed by the Telecommunications standardization sector of the
International Telecommunications Union X.805 (ITU–T X.805) on October 2003 to provide end to
end transmission of data from one network to another.
The Security architecture logically separates complicated arrangement of end to end system's
security related features into discrete architectural components. This discretion allows a certain
systematic way to deal with end to end security that can be utilized for planning of new security
solutions and for accessing the security of the current networks. The security architecture gives a
complete, top–down, end–to–end point of view of system security and can be connected to network
components, administrations, and applications keeping in mind the end goal to distinguish,
anticipate, and correct security vulnerabilities.
There are various threats that should be taken into consideration since these threats are likely to
destruct, corrupt remove disclose or interrupt any information or services that helps in the efficiency
of an application.
The main issues that X.805 addresses are shown below:
1. What are the threats that can occur and what kind of protection can be provided?
2. What are the distinct types of network equipment and facility groupings that need to be

complies with the myriad of federal and state regulations is becoming increasingly difficult. As part
of this digital transformation, healthcare organizations are partnering with cloud companies, data
processors, and other organizations that must also comply with HIPAA business associate
requirements. This has resulted in an increase in the scope of security challenges for healthcare
providers and their business associates.

potential threats. Network Sentry profiles each device and keeps a detailed log of every action taken,
then delivers both the threat alert as well as the contextual information to the security analysts to
expedite review. Network Sentry's detailed log also offers comprehensive reporting that can be
crucial for HIPAA audits.
HITRUST Certification
Your healthcare organization can incorporate the CSF frameworks into your business practices, or
take it a step further, and become HITRUST CSF Certified. The consolidated controls view of the
HITRUST CSF provides visibility into the controls for several regulatory requirements and the
HITRUST audit can also help you solve any potential issues prior to an official audit, avoiding
costly HIPAA fines.
Network Sentry has a strong history of providing companies with the visibility, control and
remediation necessary to successfully implement the HITRUST CSF 01 and meet HIPAA
requirements for access control. For more information on how Network Sentry can help your

Mobile Device Management And Network Security Automation...
Bradford Networks and Airwatch Provide Secure BYOD at University of California, Irvine Medical
Center
Mobile Device Management and Network Security Automation let physicians and students safely
interact with hospital systems using their personal devices.
A world–class academic medical center with a full range of acute and general–care services, UC
Irvine
Medical Center is at the forefront of medical education and research and prides itself on delivering
the highest quality patient care.
At UC Irvine Medical Center, mobile devices such as iPhones and iPads are a way of life for
doctors, professors, medical students and staff. When Allscripts, which supplies the Medical
Center's electronic medical record (EMR) system, announced it was developing a mobile app, "We
knew our doctors and medical personnel would be clamoring to use this application," explains Adam
Gold, Director of Emerging Technologies at UC Irvine Medical Center. "The time had come when
we needed a BYOD strategy that would enable our staff to securely use their own devices at the
medical center."
Several challenges would need to be overcome along the way. The most pressing concern was
protecting HIPAA–compliant data. Adam recognized that security had to start at the endpoint so
only approved, secure devices with safe would be allowed on the network.
The Challenge
Physicians, instructors, students and hospital staff interact with the EMR system in many different
ways, and these varied access levels had to be

Information Technology Security Is Vital For The Success...
IT security
Introduction
Information Technology security is vital for the success of any organization. As such, companies are
supposed to put in place proper security to prevent external attacks as well as proper internal
operations. For this reason, ZXY needs to have proper threat–vulnerability assessment and risk
likelihood determination in order to come up with proper plans to secure the company's
infrastructure and internal operations.
Threat– Vulnerability Pairing
VULNERABILITY THREAT SOURCE THREAT ACTION/ RISK
Using common passwords unauthorized users, disgruntled employees Unauthorized data
modification or deletion,
Abuse of permissions and authorizations use of plastic cards for employees to sign in and sign out of
systems unauthorized users, hackers Plastic cards can be stolen;
System intrusion and unauthorized access
Lack of segregation controls Disgruntled employees, suppliers Undetected fraudulent activities
Fluctuation in quality of service
Insufficient physical controls protecting equipment Disgruntled employees; vandals from outside

Risk Mitigation Plan Based On Inputs Provided
DLIS risk manager and team will now be responsible with developing a risk mitigation plan based
on inputs provided by said team. Funds have been allocated for the plan due to the importance of
risk mitigation to the organization. Thus, senior management is committed to and supportive of the
project (ITT–Technical Institute, 2015). Documentation, training, policies and procedures are
helpful when creating, testing and implementing a new risk mitigation plan. Documentation is
extremely helpful as it gives information on where the company was before the new plan was
created, where the company will be once the plan has been implemented and where the company
will be in the future if the plan is followed. Documentation also provides details for management
and allows for easier troubleshooting methods. Training of all staff is crucial if a plan is to succeed
as the least trained individual is the company's worst enemy. Training provides up–to–date
information on new security measures as well as 'what–to–do' lists that all employees can follow in
the instance of any issues. Policies and procedures within a risk mitigation plan are set in place to
achieve the most current security methods that any company must follow in any market of today's
society. These are created not only to help a company remain secure within the network, but also
make sure that the company is compliant with all rules/regulations and laws mandated by the U.S.
Federal Government. A few of these are

Design And Implementation Of A Defense Security Perimeter...
Design and Implementation of a Defense Security Perimeter System
Network security is becoming an increasingly important concern for small and midsize companies.
A breach in internal or external security can severely damage a company's most important
operations, hampering productivity, compromising data integrity, reducing customer confidence,
disrupting revenue flow, and bringing communications to a halt. This paper examines some of the
new security challenges that confront small and midsize businesses today, and discusses how
defense security perimeter solutions for wired and wireless networks. Information security (InfoSec)
is the protection of information and its critical elements, including the systems and hardware that
use, store, and transmit that information. To protect information and its related systems, each
organization must implement controls such as policy, awareness training, security education, and
technical controls. These security controls are organized into topical areas, and any successful
organization will be able to integrate them into a unified process that encompasses this. (Whitman,
2011) MD Security Perimeter Consultants is a midsize company with 400 employees that
specializes in business to business products and services. Because all the business is with other
businesses they Information Security controls have to be simple, top of the line and scalable. In this

Annotated Bibliography On Database Security
What is a database? According to our book, it's an organized collection of logically related data. The
information collected in a database can be effortlessly administered and accessed. However, with
each database there is a concern of security. According to our book, the goal of database security is
to protect and prevent data from unintentional or deliberate threats to its integrity and accessibility.
The database environment has grown more complex, with distributed databases located on
client/server architectures and personal computers as well as mainframes. Access to data has become
more open through the Internet and corporate intranets and from mobile computing devices. As a
result, managing data security has become more difficult and time–consuming. The data collected
and distributed in every organization is a very important resource; therefore, all personnel in the
organization must be aware of the security threats present and the measure to take to prevent data
breach or leak. Data leak can occur unintentionally or intentionally. For example, if the employee is
being careless with sensitive data and leaving it in the open for others to access it this would be an
unintentional data leak. An intentional leak would be when a disgruntled employee gives sensitive
information to other competitors. The responsibility for database protection goes to the database
administration. It's their task to develop the procedures and policies to avert data breach. The
database

Basic Concepts Of Access Control System
In any given social network, the number of users might be significant, the number of resources that
must be protected might be in millions, and hence the number of access control policies that need to
be defined might be in billions. If only one permission is incorrectly granted, a user will be given
unsupervised access to information and resources which could jeopardize the security of the entire
given social network.
Presently, security of information is an indispensable responsibility for all media keeping and
sharing information with others. In practice, all applications employ access control methods to
protect their information. Access control identifies activities of legal users and governs every
attempt performed by these users to ... Show more content on Helpwriting.net ...
Hence, the following metrics are classified based upon the four categories mentioned above:
1. Ability to combine several related rules. The PBAAC decision engine is able to collect different
access control rules, consolidate similar rules and derive a result under the specified condition.
These rules can be defined by the controlling user, the target user, and the supervisor of the social
network.
2. Ability to combine access control models. Under our approach, two access control models are
combined, namely ABAC and PBAC models. By using the ABAC model, access constraints will be
defined for each entity, and by using PBAC, policies enforcing access to a resource will be defined.
Under our model, policies will be defined by controlling user, the target user, or the supervisor of
the social network.
3. Ability to enforce the least privilege principle. Our model includes an entity as supervisor who is
the administrator of the social network. The minimum privilege principle will be provided by rules
defined by the supervisor. Our model accepts new users with various associated attributes. In order
to access control mechanisms supporting the principle of the least privilege, constraints are placed
on the attributes belonging to a user.
4. Ability to resolve conflict rules. Rule

Denial-Of-Service Attacks
Figure 4: How Several Requests Sent to a Access Point Can Disrupt Network Service
A cyber–criminal can create a denial–of–service attack by sending spam emails to a network. The
spam emails can be sent to an email account supplied by an employer or a free email account
offered by Hotmail and Yahoo. With each email account, the user is assigned a specific quota that
specifies the amount of space the account can have at a given time. If the cyber–criminal sends large
amounts of spam messages to a user's email account then the quota will be exceeded and prevent the
user from receiving legitimate messages. When a denial–of–service attack is launched, the cyber–
criminal can also choose to deny authorized users' access or limit their access by creating ... Show
The café latte attack relies on a user's laptop being connected to a Wired Equivalent Privacy (WEP)
protected network and tricks the user into sending thousands of WEP–encrypted ARP (Address
Resolution Protocol) requests. An ARP is a network protocol that maps together a network layer
address and a data link layer hardware address. For example, an ARP is used to resolve IP addresses
to their corresponding Ethernet address (Leyden, 2007). For a café latte attack to be successful, the
cyber–criminal does not have to be in the same area as the user but can also be in a remote location
to intercept the WEP key. A cyber–criminal can take advantage of the message modification flaws in
the 802.1WEP architecture and the shared key authentication by flooding a network with encrypted
Address Resolution Protocol (ARP) requests. A café latte attack functions by using a bit–flipping
technique that modifies the Media Access Control (MAC) address and Internet Protocol address (IP
address) of a user's computer which is collected when gratuitous ARP requests are sent from the
cyber–criminal. When the user responds to the gratuitous ARP requests, the cyber–criminal can
quickly crack the WEP key from the user's traffic. With a café latte attack, a cyber–criminal can
obtain the WEP key in less

Security Policies And Control And Password Management...
Security policies are rules and guidelines formulated by an organization to manage access to
information systems and/or computer networks. Simply put, these policies exist to govern
employees, business partners, and third–party contractors with access to company assets.
Furthermore, some policies exist to comply with laws and regulatory requirements. These policies
are part of the company information security management system (ISMS), and are usually
administered to employees by Human Resources or distributed to business partners and contractors
via the Technology department. In sum, security policies protect assets from illegal or damaging
actions of individuals. Of course, many security policies exist, but this review will focus on the ...

How do you block infected devices without restricting the vast majority that are safe? These
questions led Cary to another key insight: "The device type doesn't matter – what's important is to
provide appropriate access and respond immediately to any security threat."
Cary created a new kind of network control for BYOD at Pepperdine that could meet the needs of a
dynamic campus community. "We need to know who is on our network, give them appropriate
access, and let them know where they stand at all times. And we need a solution that's fully
automated and user–friendly, which is easy to do with Bradford Networks' Network Sentry."

Some of these are based on virtualization of the device, others offer specialized applications for
specific business processes such as emails or VPNs. Furthermore, some products offer remote
connections to the enterprise networks. Most of these solutions, however, exhibit the disadvantage
that they either require a modification of the underlying operating system/kernel or a rooted device.
In the traditional case, the device being used by the employee is provided by the company and IT
officials of the enterprise can make the necessary modifications to the device kernel and Operating
System (OS), to enforce that the required enterprise policies cannot be bypassed by employees. For
instance, the enterprise could certify a certain OS configuration and guarantee the correct execution
of binaries. But modifying the OS of an employee device is not an appealing solution since it
prevents employees from installing updates on their devices, and it requires the consent of the
employee. Moreover, in BYOD scenarios, these solutions cannot be deployed. This stems from the
fact that given the device does not belong to the enterprise, the latter does not have any justification
in modifying the underlying

The Problem Of The Cloud Environment
Migrating from any host technology into college technology can be a very cumbersome process
filled with many problems. The first problem that will be identified will be the issue of the migration
as will we utilize a disaster recovery type migration or will there be a replication. In addition to this
migration there is also the event of users and how information will be relayed from one location to
another location. When it comes to the migration aspect of the information there are many things
that need to be taken into account such as load balancing redundancy and security controls. The
cloud environment needs to be supportive of these aspects and there should be a dictation of how
information is going to be flowing throughout the environment. VPNS are utilized to their fullest
within our infrastructure so encryption is very important as firewalls are inside of our Network
segregating out VLAN of VLAN transactions as well as domain to domain transactions. Additional
problem that will prove to be easy to understand and evolve it is software and Licensing. As this is
one aspect that can be overlooked from various people however software needs to be addressed as
we might decide to move to a different software infrastructure but keeping the same infrastructure
will be easy to maintain. Applications as well as operating systems need to be addressed when it

requesters who try to use organization's web services by sending fake requests. So there is need to
identify which request is sent by genuine requester and malicious requester. To avoid requests from

Definition of Model
An Access control model is the technique by which we can restrict the unknown user from accessing
some web services. This model works on specified set of rules. To evade the malicious user request,
System has to cross the border of security to make some identification about requester. After making
identification, Access control model can grant access or restrict the unauthorized user from
accessing web services. Some of the Previous Access control models are as following:
Role Based Access Control (RBAC) is a standout amongst the most generally utilized Web Service
access control methods. In this type of access control technique, roles are allocated to the specific
users to access the web services(Nguyen, Zhao & Yang 2010).
Attribute Based Access Control (ABAC) models make utilization of characteristics claimed by the
customers, the suppliers, and some different credits identified with the network. Decisions about
access or deny are simply based on these attributes (Yuan & Tong 2005).
Trust–Based Access Control (TBAC) frameworks are not the same as the past access control plans
following the customer trust level is rapidly figured in view of some factual investigation of
practices, activities and past access history. Subsequently, bad behaviour and violation of rules
specified by service provider lead to a diminishing of the trust level, while great conduct prompts an

It is also possible under some operating systems for the network or system administrator to dictate
which permissions users are allowed to set in the ACL's of the resources. Discretionary Access
Control has a more flexible environment than Mandatory Access Control, but also increases the risk
that data will be made accessible to users who should not gain access. Understanding permissions
about the security of file servers on the network will increase network security (Bushmiller, 2011).
2 Mandatory access control
Describe how and why mandatory access control will be used.

Mandatory Access Control (MAC) uses a hierarchy approach to control access to resources, such as
data files. The system administrator is responsible for the settings in a MAC environment. All access
to resource objects is controlled by the operating system based on setting configured by the system
administrator. With MAC it is not possible for users to change the access control for any resource.
Mandatory Access Control starts with security labels, which contain two types of information and
are assigned to all resource objects on the system. The two types of information are classification,
such as confidential or top secret and a category, which is basically an indication of the project or
department to which the object is available, or an indication of the management level.

How To Manage Iot And Byod Threats While Still Preserving
How to manage IoT and BYOD threats while still preserving productivity Sizing–up the threat
Securing Bring Your Own Device (BYOD) & Internet of Things (IoT) devices are currently two of
the most challenging areas of network security. BYOD has been a trend for a number years now, yet
many companies are still struggling to successfully secure these endpoint devices. Organizations are
grappling with different security approaches. While some organization have not taken steps to
secure these endpoints yet, other organizations have added Enterprise Mobility Management (EMM)
technologies such as Mobile Application Management (MAM), Mobile Device Management
(MDM), Mobile Content Management (MCM) and Mobile Information Management (MIM), or a ...
The network integration, and therefore the exposure, is much deeper than BYOD, and IoT devices
usually have very little security, and generally nothing close to enterprise grade security. The first
major IoT device attack shocked the industry in October of 2016, before IoT devices were really in
the enterprise space. An hacker launched an IoT DDoS attack on Dyn, using the Mirai virus to infect
vulnerable IoT home security devices and turned them into attack bots focused on the Dyn
enterprise network (for more information see our blog on this topic). This sent ripples of fear
through organizations that realized attackers could soon leverage enterprise IoT devices to attack
internal networks. To counter the threat IoT devices introduce, organizations need to secure all
endpoints. This white paper will explore endpoint security, and how the NAC solutions of yesterday
have evolved into broader Security Automation and Orchestration Solutions designed as a security
integrator that coordinates all endpoint visibility, control and automated response, which ensures
secure enterprise adoption of both IoT and BYOD devices. The Changing Landscape As
organizations rapidly add IoT and BYOD devices, it is critical to ensure this access does not
compromise network security. In the past, enterprise networks were self–contained within

drawback or weaknesses that is anyone could get access when he or she steals the card. In this
particular paper, the RFID technology is combined or integrated with facial recognition (biometric)
technology to make sure that the granted access matches the user ID on the ... Show more content on

The RFID technology consists of three key elements: RFID tags, RFID readers, and a back–end
database server to identify information. The RFID tag stores its particular ID and some application
data for RFID readers thus the tag contains electronically stored information which is used for
access control system. The major advantage of using the RFID tag is that it allows convenience
contactless access. However, the traditional RFID–based access control system identifies an
individual only by means of his or her RFID card that is anyone who presents a registered RFID
card will pass the authentication even he/she is not the genuine card holder or owner. Moreover,
there are many RFID attacks which are:
Sniffing – this is reading data from a RFID chips without being given a permission;
Spoofing – this is the cloning of information from one chip to another
Tracking – this involves the tracking of goods or services without acknowledging the owner.
Denial of Service – this involves the jamming of RFID signals to block its normal
