for an authentic arrangement time and date and provides an accessible way to keep
the alarm constant and authentic beyond time zones application NTP.
In this section, you will apprentice how accessible it is to configure the PIX firewall for
an authentic alarm and how NTP can be acclimated for affluence of managing the clock.You
will apprentice how to configure the PIX for aurora accumulation time.You will additionally learn
that assorted PIX firewalls can be set from a axial server and how to configure
NTP on the PIX to use a axial server securely.
