File Allocation Systems or FAT

FAT viruses infect the file allocation systems of the computer and gain access to the location of all the files. It can even be programmed to selectively destroy certain files once it gains access to the file allocation system, it can even wipe out complete directories. A lot of important files are split or fragmented into a number of parts. FAT viruses are capable of detecting and tracking all of these fragments and therefore effectively gain control over all the files on the system.

Cyrptography and Network Security

Network security concerns itself with the protection of networks against unauthorized access or surveillance.  Network security protocols defend the network against malware, alteration of its programs or the deletion of important files. Cryptography and subsequently encryption are one of the most of the most important aspects of network security.

Cyrptographic attack explained

Encryption is used to protect sensitive data from a malicious hacker. This is precisely why cryptographic attacks are one of the most popular forms of cyber-attacks in the world. Successfully comprising a cryptographic system means complete and unlimited access to all the information that is being transmitted in the network.

Man-In-The-Middle Attack Prevention

In computer cryptography and cybersecurity, a man-in-the-middle attack is characterized by the presence of a foreign between two communicating parties. The third party is privy to every piece of information that is carried out and has the capability to alter the contents.

A common example of a man-in-the-middle attack involves the attacker placing himself between an unencrypted Wi-Fi and other clients. The attacker can then monitor the online activities of every client and even exhibit control over the network.

The attacker either impersonates the authentication procedure necessary for access or bypasses it altogether due to the presence of vulnerabilities. The attacker then successfully impersonates the endpoints of the network and appears completely legitimate. Most connections and protocols today employ cryptographic techniques that provide secure endpoint authentication and prevents such man-in-the-middle attacks.
