Tools used to establish secure Internet communications

Tools used to establish secure Internet communications channels• WPA2—the most current wireless security

standard uses the AES algorithm for encryption and CCMP, a more advanced authentication code protocol

Tools to protect networks, the servers, and clients

• Firewalls—software applications that act as filters between a company’s private network and the Internet itself, preventing unauthorized remote client computers from attaching to your internal network.

• Proxies—software servers that act primarily to limit access of internal clients to external Internet servers and are frequently referred to as the gateway.

Tools to protect networks, the servers, and clients
