31 Confidentiality The WEP protocol attempts some form of confidentiality by using the RC4 stream cipher algorithm to encrypt wireless communications. The standard for WEP specifies support for a 40-bit WEP key only; however, many vendors offer nonstandard extensions to WEP that support key lengths of up to 128 or even 256 bits. WEP also uses a 24-bit value known as an initialization vector (IV) as a seed value for initializing the cryptographic keystream. Ideally, larger key sizes translate to stronger protection, but the cryptographic 31.

There are quite a few different levels of protection a firewall can provide, depending on the type of firewall that is deployed, such as these: Packet filtering. The most basic type of firewalls perform what is called stateful packet filtering, which means that they can remember which side initiated the connection, and rules (called access control lists, or ACLs) can be created based not only on IPs and ports but also depending on the state of the connection (meaning whether the traffic is going into or out of the network).
