Cyber crime
Cyber crimeyazad dumasia Cybercrime is on the rise globally and in India. India ranks 11th in the world for cybercrime, constituting 3% of global cybercrime. Common cybercrimes in India include denial of service attacks, website defacement, spam, computer viruses, pornography, cyber squatting, cyber stalking, and phishing. While Indian laws against cybercrime are well-drafted, enforcement has been lacking, with few arrests compared to the number of reported cases. Increased internet and technology use in India has contributed to higher cybercrime rates in recent years. Stronger enforcement is needed to curb the growth of cybercrimes in India.

What is Cyber Crime?
Computer crime, or cybercrime, is crime that involves a computer and a network. The computer may have been used in the commission of a crime, or it may be the target.
What is Cyber Security?
C
yber security, also known as computer security or IT security, is the protection of information systems from theft or damage to the hardware, the software, and to the information on them, as well as from disruption or misdirection of the services they provide. It includes controlling physical access to the hardware, as well as protecting against harm that may come via network access, data and code injection and due to malpractice by operators,whether intentional, accidental, or due to them being tricked into deviating from secure procedures.
The field is of growing importance due to the increasing reliance on computer systems in most societies and the growth of "smart" devices,including smartphones, televisions and tiny devices as part of the Internet of Things – and of the Internet and wireless network such as Bluetooth and Wi-Fi.
Some organizations are turning to big data platforms, such as Apache Hadoop, to extend data accessibility and machine learning to detect advanced persistent threats.
Vulnerabilities and Attacks
Vulnerability is a system susceptibility or flaw, and much vulnerability are documented in the Common Vulnerabilities and Exposures (CVE) database and vulnerability management is the cyclical practice of identifying, classifying, remediating, and mitigating vulnerabilities as they are discovered.
An exploitable vulnerability is one for which at least one working attack or "exploit" exists.
To secure a computer system, it is important to understand the attacks that can be made against it, and these threats can typically be classified into one of the categories below.

Website Hacking and Preventive Measures
Website Hacking and Preventive MeasuresShubham Takode Today is the age of computer and internet. More and more people are creating their own websites to market their products and earn more profit from it. Having our own website will definitely help us in getting more customers purchasing our products but at the same time we can also attract hackers to play around with our website. If we have not taken enough care to protect our website from hackers then our business can even come to an end because of these hackers. If we own a website, then we might know the importance of ensuring that our website is safe from viruses and hackers.
After going online most of the website designers think that their work is over. They have delivered what they were paid for and now they will be available for the maintenance of the site only. But sometimes the main problem starts after publishing the website. What if the website they have built suddenly start showing different stuff from what was already present there? What if weird things start appearing on the pages of our website? And most horribly what if the password of our login panel has changed and we are not able to login into our website. This is called hacking, a website hacking. We have to figure out how this happened so we can prevent it from happening again. In this seminar we are going to discuss some of major website hacking techniques and we are also going to discuss how to prevent website from getting vulnerable to different attacks currently use by various hackers.

Toward Continuous Cybersecurity With Network Automation
Toward Continuous Cybersecurity With Network AutomationKen Flott Network security is a dynamic art, with dangers appearing as
fast as black hats can exploit vulnerabilities. While there are
basic “golden rules” which can make life difficult for the bad
guys, it remains a challenge to keep networks secure. John
Chambers, Executive Chairman of Cisco, famously said “there
are two types of companies: those that have been hacked, and
those who don’t know they have been hacked”. The question
for most organizations isn’t if they’re going to be breached, but
how quickly they can isolate and mitigate the threat.
In this paper, we’ll examine best practices for effective
cybersecurity – from both a proactive (access hardening)
and reactive (threat isolation and mitigation) perspective.
We’ll address how network automation can help minimize
cyberattacks by closing vulnerability gaps and how it can
improve incident response times in the event of a cyberthreat.
Finally, we’ll lay a vision for continuous network security, to
explore how machine-to-machine automation may deliver an
auto-securing and self-healing network.

ADVXAI IN MALWARE ANALYSIS FRAMEWORK: BALANCING EXPLAINABILITY WITH SECURITY
ADVXAI IN MALWARE ANALYSIS FRAMEWORK: BALANCING EXPLAINABILITY WITH SECURITYijscai With the increased use of Artificial Intelligence (AI) in malware analysis there is also an increased need to
understand the decisions models make when identifying malicious artifacts. Explainable AI (XAI) becomes
the answer to interpreting the decision-making process that AI malware analysis models use to determine
malicious benign samples to gain trust that in a production environment, the system is able to catch
malware. With any cyber innovation brings a new set of challenges and literature soon came out about XAI
as a new attack vector. Adversarial XAI (AdvXAI) is a relatively new concept but with AI applications in
many sectors, it is crucial to quickly respond to the attack surface that it creates. This paper seeks to
conceptualize a theoretical framework focused on addressing AdvXAI in malware analysis in an effort to
balance explainability with security. Following this framework, designing a machine with an AI malware
detection and analysis model will ensure that it can effectively analyze malware, explain how it came to its
decision, and be built securely to avoid adversarial attacks and manipulations. The framework focuses on
choosing malware datasets to train the model, choosing the AI model, choosing an XAI technique,
implementing AdvXAI defensive measures, and continually evaluating the model. This framework will
significantly contribute to automated malware detection and XAI efforts allowing for secure systems that
are resilient to adversarial attacks.
Introduction to FLUID MECHANICS & KINEMATICS
Introduction to FLUID MECHANICS & KINEMATICSnarayanaswamygdas Fluid mechanics is the branch of physics concerned with the mechanics of fluids (liquids, gases, and plasmas) and the forces on them. Originally applied to water (hydromechanics), it found applications in a wide range of disciplines, including mechanical, aerospace, civil, chemical, and biomedical engineering, as well as geophysics, oceanography, meteorology, astrophysics, and biology.
It can be divided into fluid statics, the study of various fluids at rest, and fluid dynamics.
Fluid statics, also known as hydrostatics, is the study of fluids at rest, specifically when there's no relative motion between fluid particles. It focuses on the conditions under which fluids are in stable equilibrium and doesn't involve fluid motion.
Fluid kinematics is the branch of fluid mechanics that focuses on describing and analyzing the motion of fluids, such as liquids and gases, without considering the forces that cause the motion. It deals with the geometrical and temporal aspects of fluid flow, including velocity and acceleration. Fluid dynamics, on the other hand, considers the forces acting on the fluid.
Fluid dynamics is the study of the effect of forces on fluid motion. It is a branch of continuum mechanics, a subject which models matter without using the information that it is made out of atoms; that is, it models matter from a macroscopic viewpoint rather than from microscopic.
Fluid mechanics, especially fluid dynamics, is an active field of research, typically mathematically complex. Many problems are partly or wholly unsolved and are best addressed by numerical methods, typically using computers. A modern discipline, called computational fluid dynamics (CFD), is devoted to this approach. Particle image velocimetry, an experimental method for visualizing and analyzing fluid flow, also takes advantage of the highly visual nature of fluid flow.
Fundamentally, every fluid mechanical system is assumed to obey the basic laws :
Conservation of mass
Conservation of energy
Conservation of momentum
The continuum assumption
For example, the assumption that mass is conserved means that for any fixed control volume (for example, a spherical volume)—enclosed by a control surface—the rate of change of the mass contained in that volume is equal to the rate at which mass is passing through the surface from outside to inside, minus the rate at which mass is passing from inside to outside. This can be expressed as an equation in integral form over the control volume.
The continuum assumption is an idealization of continuum mechanics under which fluids can be treated as continuous, even though, on a microscopic scale, they are composed of molecules. Under the continuum assumption, macroscopic (observed/measurable) properties such as density, pressure, temperature, and bulk velocity are taken to be well-defined at "infinitesimal" volume elements—small in comparison to the characteristic length scale of the system, but large in comparison to molecular length scale

- 2. Hacking • Hacking is a technique to steal the data and interrupt flow. Cyber Security ‘Cybersecurity is the body of technologies, processes and practices designed to protect networks, computers, programs and data from attack, damage or unauthorized’ • The Security provided by different companies and organizations for the Online data and sofwares is called Cybersecurity.
- 3. Cyber Security • ‘A major part of Cyber Security is to fix broken software’ Hacking • ‘A major attack vector of Cyber Crime is to exploit broken software’
- 4. Details on Cyber Security ‘Although targeted vulnerabilities may have already been patched by vendors, hackers bank on user negligence when it comes to installing software updates. As an example, people are notoriously slow in installing Java patches to PCs and Macs. As much as 60 percent of Java installations are never updated’ "All these un-updated applications on the desktop, whatever they may be, are low-hanging fruit. These are the easiest things to attack.“ http://www.csoonline.com/article/712640/hackers-increasingly-aim-for-cross-platform-vulnerabilities

- 10. XSS - What Is Cross-Site Scripting? • Scripting (also known as XSS) is one of the most common application-layer web attacks. XSS vulnerabilities target scripts embedded in a page that are executed on the client-side (in the user’s web browser) rather than on the server-side
- 11. SS7 -Signalling system 7 • This Hacking is very old but still in market . Its related with whole network. • Its quite similar to man in middle attack. • We are unable to solve his because if we wan to then we need lots of money to replace whole network System.(just like OSI / TCP-IP protocol)
- 12. SS7
- 14. Bruit Force Attack • Try random Password one by one and give user’s password • trial and error method • Speed of cracking Depends upon processor(hashing algo.) • Common tool used to hack is Hydra.
- 15. Virus Attack • Virus is a software that is designed for attacker. • It may have different tasks. • Spying on other computer , Steal password and details, harm the computer • Prorat is a tool b which you can create such viruses.
- 16. Other • This field has full of possibilities of coming new Hacks and new Security System. • Most of the Govt. are spending lots of money in Cyber Security . • • India needs to pay attencion o his side o secure he services because India has limited Govt. staff o see after he cases of online fraud and all.
- 17. TYPES OF CYBER ATTACK BY PERCENTAGE • Financial fraud: 11% • Sabotage of data/networks: 17% • Theft of proprietary information: 20% • System penetration from the outside: 25% • Denial of service: 27% • Unauthorized access by insiders: 71% • Employee abuse of internet privileges 79% • Viruses 85%
