Mostly protect data from natural disasters
Unauthorized Access
• Passwords
• Locks
Some computers may have locks on them.
• Biometrics Locks.
Bio Matrix system- to protect data from unauthorized access
Pass word- to protect from unauthorized access

Antivirus
Hardware protection
• UPS (uninterrupted power supply )-to avoid the risk of sudden power failure and fluctuations
• Stabilizer – to control the voltage• Surge protection- to protect
agents lightning and thundering
• Surge protection to protect against lightening & thunder.
• Stabilizer –To control the voltage.
COMPUTER & SECURITY
We can mainly divided computer & security for the 3 parts.
