What is the Importance And Use of Network Security Issues PDF?
A list of computer security vulnerabilities, like buffer overflow and cross-site scripting, can be to attack a network.
The first step to securing a network from attack is to use the latest available software. Also, hardware, unless the older equipment is for compatibility with older software.
Keep all software current and up-to-date, and ensure all software is proper.
Ensure that all operating systems are up-to-date because security risks are often through updates. So these should be as soon as they are available.
Ensure that all antivirus and anti-malware software is with the latest definition files. It is because these software packages can be to prevent many types of attacks and threats.
Some of the common security attacks on a network include:
Attacks
Network Security attacks are usually from the Internet. For example, a malicious hacker can launch a DDoS attack to crash down a network or website so that legitimate users are unable to access the resources.
Denial-of-service (DoS) attack is a type of network attack that involves an attempt to make a computer resource unavailable to its intended users.
This attack is out by flooding the computer resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled.
The distributed denial-of-service (DDoS) attack is by multiple computers, which are often with a Trojan (or “bot”), controlled via a Command and Control server.
Attackers
And these attacks can be:
Attackers have different motives behind the attacks, including political, criminal, or even terrorist reasons.
The main motive behind an attack could be an attempt to gain unauthorized access to your data or resources. Why? It is to cause damage to a computer system, to spread a computer virus or worm, to gain personal information, or just for fun.
What is the List of Common Threats and Risks?
A malicious code or program that gets into your computer without your knowledge and performs actions that you did not authorize. Also known as a “Trojan horse”.
A virus is a type of malicious code that attaches itself to another program and spreads by inserting a copy of itself into any other executable program.
A worm is a program that replicates itself. If a computer is with a worm, then it can spread the worm to computers on the network connected to it.
A bot is a program that runs automated tasks over the Internet. Bots are often used for malicious purposes, such as sending spam messages or launching distributed denial-of-service (DDoS) attacks.
Ransomware is malware that encrypts your computer files and holds them, hostage, until you pay ransom to get the files back.
Conclusion
The most important aspects of wireless security are encryption and authentication. Encryption is to protect data and authentication is to prevent unauthorized access.
Both are commonly used together in providing more security than using either by itself.
