Back doors: A cryptosystem or a back door in any computer system is the secret method of bypassing the security controls or normal authentication. Also, there may be several reasons for it to exist like including any original design or from poor configuration.

Direct access attack: An unauthorized user that is gaining the physical access resource and which is not available to him.

Spoofing: Spoofing of the user identity that describes a situation in which a program or one person successfully masquerades as another person with the use of false data.

Eavesdropping: It is the act of listening to a private conversation. Also, it typically happens between the hosts on a network.

Cluster viruses: If a program is running from the infected disk, the program also causes the virus to run. So, the technique creates a sort of illusion that the virus uses to infect all the programs on the disk.

Boot sector virus: This kind of virus infects the boot record part of a hard disk. It allows for the actual boot sector data to be read through a normal startup.

Trojan horses: A trojan horse is a malicious program that also appears as friendly. Also, this virus does not make any duplicate of themselves and store it on the host’s disk.
