Threats to Cyber/Computer System Security

Risks to cyber/computer systems data include physical theft, logical usurpation, application damage through viral attack, and “social engineering” attacks. For example, the possibility is very high that any organization with more than twenty workers will have lost laptops or handhelds in the past year. The associated costs for such losses are usually determined only for replacement costs—which doesn’t include the value of the lost data—both the monetary and security value of the data. Count up all of the replacement costs, including equipment, software, and restoring or replacing data, and the reasoning behind why staff should be taught clear policies, procedures, and the importance of cyber/computer security and the presence of risks becomes clear.

Computer system risks mean that any complete security program pays attention to all risk areas. That means developing ways to protect

■ The physical equipment itself, including desktop computers (whether office based or home computers supplied by the company) and the associated peripherals (output devices like printers, input devices like scanners, and data transfer, backup, and storage devices, like Zip drives or CD or DVD drives, whether external or internal); laptop computers and their associated gear; and an ever-widening body of handheld devices, including PDAs, bar-code readers, and many different types of data readers.

■ Logical assets, including IP and other network configuration information

■ Application and data integrity

■ Password integrity

Different types of equipment present different security needs. Laptops are easier to physically steal than desktop units but are more apt to be the targets of incidental theft, not a deliberate plan to steal a particular unit because of the data it contains. More important is the protection of the computer system and the information held within the system, which may have value or may simply be vulnerable to hackers.
