Unauthorized Access

• Passwords

• Locks

Some computers may have locks on them.

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.
