Firewalls and Intrusions
Firewalls are designed to block clearly suspicious traffic and forward other traffic through.
Many exploits take advantage of weaknesses in the protocols that are allowed through the
firewall, so that once an inside server has been compromised it can be used as a backdoor to
launch attacks on other servers.
Firewalls are usually deployed at the network edge. However, many attacks (inadvertently) are
launched from within an organization. Virtual private networks (VPN), removable storage
devices and wireless networks may all provide access to the internal network without going
through the firewall.
