The attack surface of a system is that part of the system that may be exposed to access or modification of unauthorized users. The term is mainly used in computer science. The greater the surface, the more the system is vulnerable.
This concept includes:
An approach to computer security is to reduce the attack surface, making the system or software harder to attack. This approach is not very effective in limiting the damage an attacker can do when he or she finds a vulnerability, but still reduces the chance of finding one. An example in the IP modifies wikitesto networks
If a server must provide two services (for example HTTP and FTP), all other system ports must be closed. If there is also a mail server software, this should be deleted because it could be exploited by an attacker to try to violate the system. Deleting this unnecessary service reduces the attack surface. Links externalize the wikitesto
