Firewall and Router Assessment

Firewall and Router Assessment

An important part of this stage is access control verification. Routers
are checked to ensure they appear to be configured with suitable filters
by trying to reach host devices behind them. Checks are made to
ensure redundant TCP/UDP traffic and ICMP traffic is disabled.
Similarly firewalls are checked to ensure that all direct connection
attempts are dropped, and whether connection attempts to internal
systems appear to be blocked as necessary. The security of the
underlying operating systems is tested as well.
Firewalls and routers are essential networking components that should
be secured adequately. This assessment phase is intended to ensure
that the necessary restrictions are in place to govern access to the
internal company network.
