, 1 Physical Security
1.1 CCTV
CCTV which stands for closed-circuit television can be installed in good hiding positions to
put off any hackers or thieves and prevent them from doing anything dodgy and will help
keep the systems secure.
1.2 Good locks
The lock and key security and good use of high quality locks on doors and entrances into any
organisations buildings. Locks can also have passkeys associated with them making them
even more secure then they usually are.
1.3 Bio metrics
Bio metric security is a security used to authenticate and give access to a facility or system
based retinal scanning, voice and fingerprint technology. Because bio metric security takes a
scan at someone bodily features or biological data, it is the strongest and most fool proof
physical security technique used for identity verification. Making it very good for keeping
systems secure.
