Protection of physical assets from enemies
(traditional definition)
Security (Wikipedia): The degree of resistance to, or protection
from, harm.
Computer Security (William Stalling): The protection to an automated
information system to preserve the integrity, availability, and
confidentiality of information system resources. [also called Cyber
Security or IT Security] OR
A study to prevent unauthorized access to IS related to data,
hardware or software. (I prefer it).
Software Security: A study to prevent bugs in code.
Network Security: A study to prevent unauthorized access to data
of a network resources. (I prefer it).

Network security
Network securityNandini Raj Network security involves securing computer networks from threats and attacks. There are four main types of attacks: interruption, interception, modification, and fabrication. An attack generally involves initial information gathering, network probing, unauthorized access, capturing the network, and grabbing or destroying data. Intrusion detection systems monitor network activity for signs of intrusion and report alerts. There are two main types of IDS: knowledge-based which uses signatures, and behavior-based which monitors for anomalies. Virtual private networks provide a secure channel over untrusted networks using protocols like SSL and IPSec to authenticate users and encrypt data.

Transport Layer Port or TCP/IP & UDP Port
Transport Layer Port or TCP/IP & UDP PortNetwax Lab A port is an application-specific or process-specific software construct serving as a communications
endpoint in a computer's host operating system. The purpose of ports is to uniquely identify different
applications or processes running on a single computer and thereby enable them to share a single
physical connection to a packet-switched network like the Internet. In the context of the Internet
Protocol, a port is associated with an IP address of the host, as well as the type of protocol used for
communication.

Tcp and udp
Tcp and udpAhmad Khalid Nasrat TCP guarantees reliable delivery of data packets in the correct order, while UDP does not provide these guarantees. TCP is commonly used for applications that require reliable data transfer like HTTP and FTP. UDP is used for applications that prioritize speed over reliability, such as media streaming, VoIP, and online games. While TCP ensures error-free transmission, it introduces more overhead and latency than UDP. The choice between TCP and UDP depends on an application's requirements for reliability versus speed.

Optimal Security Response to Network Intrusions in IT Systems
Optimal Security Response to Network Intrusions in IT SystemsKim Hammar Cybersecurity is one of the most pressing technological challenges of our time and requires measures from all sectors of society. A key measure is automated security response, which enables automated mitigation and recovery from cyber attacks. Significant strides toward such automation have been made due to the development of rule-based response systems. However, these systems have a critical drawback: they depend on domain experts to configure the rules, a process that is both error-prone and inefficient. Framing security response as an optimal control problem shows promise in addressing this limitation but introduces new challenges. Chief among them is bridging the gap between theoretical optimality and operational performance. Current response systems with theoretical optimality guarantees have only been validated analytically or in simulation, leaving their practical utility unproven.
This thesis tackles the aforementioned challenges by developing a practical methodology for optimal security response in IT infrastructures. It encompasses two systems. First, it includes an emulation system that replicates key components of the target infrastructure. We use this system to gather measurements and logs, based on which we identify a game-theoretic model. Second, it includes a simulation system where game-theoretic response strategies are optimized through stochastic approximation to meet a given objective, such as quickly mitigating potential attacks while maintaining operational services. These strategies are then evaluated and refined in the emulation system to close the gap between theoretical and operational performance.
We present CSLE, an open-source platform that implements our methodology. This platform allows us to experimentally validate the methodology on several instances of the security response problem, including intrusion prevention, intrusion response, intrusion tolerance, and defense against advanced persistent threats. We prove structural properties of optimal response strategies and derive efficient algorithms for computing them. This enables us to solve a previously unsolved problem: demonstrating optimal security response against network intrusions on an IT infrastructure.

CBSE - Grade 8 - Science - Chemistry - Metals and Non Metals - Worksheet
CBSE - Grade 8 - Science - Chemistry - Metals and Non Metals - WorksheetSritoma Majumder Introduction
All the materials around us are made up of elements. These elements can be broadly divided into two major groups:
Metals
Non-Metals
Each group has its own unique physical and chemical properties. Let's understand them one by one.
Physical Properties
1. Appearance
Metals: Shiny (lustrous). Example: gold, silver, copper.
Non-metals: Dull appearance (except iodine, which is shiny).
2. Hardness
Metals: Generally hard. Example: iron.
Non-metals: Usually soft (except diamond, a form of carbon, which is very hard).
3. State
Metals: Mostly solids at room temperature (except mercury, which is a liquid).
Non-metals: Can be solids, liquids, or gases. Example: oxygen (gas), bromine (liquid), sulphur (solid).
4. Malleability
Metals: Can be hammered into thin sheets (malleable).
Non-metals: Not malleable. They break when hammered (brittle).
5. Ductility
Metals: Can be drawn into wires (ductile).
Non-metals: Not ductile.
6. Conductivity
Metals: Good conductors of heat and electricity.
Non-metals: Poor conductors (except graphite, which is a good conductor).
7. Sonorous Nature
Metals: Produce a ringing sound when struck.
Non-metals: Do not produce sound.
Chemical Properties
1. Reaction with Oxygen
Metals react with oxygen to form metal oxides.
These metal oxides are usually basic.
Non-metals react with oxygen to form non-metallic oxides.
These oxides are usually acidic.
2. Reaction with Water
Metals:
Some react vigorously (e.g., sodium).
Some react slowly (e.g., iron).
Some do not react at all (e.g., gold, silver).
Non-metals: Generally do not react with water.
3. Reaction with Acids
Metals react with acids to produce salt and hydrogen gas.
Non-metals: Do not react with acids.
4. Reaction with Bases
Some non-metals react with bases to form salts, but this is rare.
Metals generally do not react with bases directly (except amphoteric metals like aluminum and zinc).
Displacement Reaction
More reactive metals can displace less reactive metals from their salt solutions.
Uses of Metals
Iron: Making machines, tools, and buildings.
Aluminum: Used in aircraft, utensils.
Copper: Electrical wires.
Gold and Silver: Jewelry.
Zinc: Coating iron to prevent rusting (galvanization).
Uses of Non-Metals
Oxygen: Breathing.
Nitrogen: Fertilizers.
Chlorine: Water purification.
Carbon: Fuel (coal), steel-making (coke).
Iodine: Medicines.
Alloys
An alloy is a mixture of metals or a metal with a non-metal.
Alloys have improved properties like strength, resistance to rusting.
