SOME ESSENTIAL TERMINOLOGIES

Before proceeding  further, the following are some of the essential terminologies in the field of hacking that one should be aware of:

Vulnerability: A Vulnerability is an existing weakness that can allow the attacker to compromise the security of the system.

Exploit: An exploit  is  a defined way (piece of software, set of commands etc.) that
takes advantage of an  existing vulnerability to breach the security of an  IT system.

Threat: A threat  is  a possible danger that can exploit an existing vulnerability to
cause possible harm.

Attack: An attack is any action that violates the security of the system. In other
words, it  is  an assault on the system security that is derived from an existing threat.
