Computer Security Risks
Weak or No Encryption
Wireless networks with weak or no encryption that can be accessed easily by
anyone driving by with a wireless-enabled laptop.
Reducing the risks
to encode data during storage or transmission so
that it cannot be understood by someone who
does not have the encryption key or software
to convert it back to its original form
Computer Security Risks
Hardware malfunction is a risk because data can be corrupted by
bad power and over- heating. . Bad power not only damage
hardware but it could damage important system file.
Reducing the risks
the use of uninterruptible
power supply (UPS) and
