    • Useful in monitoring access system
Equipment access
  • Procedures for controlling theft and unauthorized access must be provided
    • Keep current inventory including date of purchase, serial no., cost
    • Tag with ID no. both inside and out

    • hardware and/or software that controls information entering your computer system or network
  • Intrusion detection software
    • detects unauthorized intrusions into your computer systems
  • Encryption
    • a security method that transforms information into random streams of bits to create a secret code. There is software-based encryption such as Public Key Infrastructure (PKI) and Secure Sockets Layer (SSL). Hardware-based encryption, such as smart cards, is another type of encryption.
  • PKI
    • the combination of software, encryption technologies, and services that enables enterprises to protect the security of their communications and business transactions on the Internet.

Nonremovable media security
  • To prevent access to data stored on hard disks must control access to equipment
    • Assigned numeric code for each person, a password or combination of the two
Removable media security
  • Key and lock for disks
  • Deny access to employees who resign, then immediately change access codes
  • Encrypt (scramble) sensitive and confidential files
  • Mutilate or erase disks before disposal
  • Turn off modems when not in use
  • Turn off computers when not in use so unauthorized users cannot access files
Virus protection
  • Use and update antivirus software
