TAILIEUCHUNG - Network Perimeter Security

LANs, WANs, WLANs are known as edge networks May be contained within businesses or homes Needs to be protected from the rest of the Internet! Why firewall? Encryption? Cannot stop malicious packets from getting into an edge network Authentication? Can determine whether an incoming IP packet comes from a trusted user However, not all host computers have resources to run authentication algorithms Host computers managed by different users with different skill levels. | J.
