Network Security Some DoS attacks can be avoided by applying vendor patches to the software that has been compromised. Another way to deal with DoS attacks in the case of an attack coming from a number of known IP addresses is to put up a rule to drop all incoming traffic from those known attackers. Yet another way to deal with these types of attacks is to set up packet filters. This will act as a proxy for connections. Once the handshake is validated it will be forwarded to the correct destination

Computer security and cryptography A computer program system that is supposed to be used only by those authorized must attempt to detect and exclude the unauthorized. Access to it is therefore usually controlled by insisting on an authentication procedure to establish with some degree of confidence the identity of the user‚ thence granting those privileges as may be authorized to that identity. Common examples of access control involving authentication include: * A captcha is a means of asserting
