Network security 2
- Physical security
- First line of defence -
preventing
unauthorised people
from entering
buildings where
network equipment is
locked up
- Keep access doors
locked using keypads,
fingerprint pads etc
- Biometric security
recognition can be
used on mobile
devices to
authenticate users
- Use swipe cards
containing user's
details to enter the
building
- Install closed circuit
television to
monitor interior and
exterior of building
- Install burglar
alarms in all
rooms
- Fit radio frequency
identification (RFID) chips
to all equipment so an
alarm will sound if the
equipment is taken out
of the building
- Use chains and
locks so
equipment can't
be stolen
- First line of defence -
preventing
unauthorised people
from entering
buildings where
network equipment is
locked up
- Firewalls
- Firewalls protect
a network
connected to a
WAN such as the
internet
- They can be
provided by
hardware or
software
- They can be configured
to prevent
communications from
entering the network
- They can prevent
programs and users
from accessing the
internet from within
the network
- Individual computers
usually have a software
firewall which have default
rules installed onto them
to protect the computer
from common threats
- A business with a LAN
and a internet
connection is likely to
have a hardware
based firewall
because they have
more flexibility in the
rules that can be
applied and data
throughput is faster

a network
