7.1 Introduction
Technicians need to understand computer and network security. Failure to implement proper security procedures can have an impact on users, computers, and the general public. Private information, company secrets, financial data, computer equipment, and items of national security are placed at risk if proper security procedures are not followed.
7.2 Explain why security is important
Computer and network security help to keep data and equipment functioning and provide access only to appropriate people. Everyone in an organization should give high priority to security because everyone can be affected by a lapse in security.
Theft, loss, network intrusion, and physical damage are some of the ways a network or computer can be harmed. Damage or loss of equipment can mean a loss of productivity. Repairing and replacing equipment can cost the company time and money. Unauthorized use of a network can expose confidential information and reduce network resources.
An attack that intentionally degrades the performance of a computer or network can also harm the production of an organization. Poorly implemented security measures to wireless network devices demonstrate that physical connectivity is not necessary for unauthorized access by intruders.
7.3 Describe security threats
To successfully protect computers and the network, a technician must understand both types of threats to computer security:
Physical – Events or attacks that steal, damage, or destroy equipment, such as servers, switches, and wiring
Data – Events or attacks that remove, corrupt, deny access, allow access, or steal information
