Question
Computer systems are exposed to security risks that threaten the security and integrity of both the system and data held in it. These threats are becoming increasingly sophisticated and seem to multiply by the day, resulting in endless headaches for IT professionals.
With each new piece of technology arriving on the scene, a security threat seems to accompany it. The key for IT is to constantly evaluate current security measures and policies to identify any shortcomings that may be exposing the company to risk.
Required: Explain THREE main risks that threaten security and integrity of systems and data held in them and TWO ways to minimize such risks. (10 marks)
Answer
Security Risks:
- Hackers and Eavesdroppers: They attempt to gain unauthorized access to computer systems. This may include efforts to damage a system or steal information. Data transmitted across telecommunications links is vulnerable to interception or examination during transmission (eavesdropping).
- Viruses: These can destroy information or data. Viruses are malicious programs that can replicate themselves and spread to other systems, causing significant harm.
- Denial of Service Attack: This involves an organized attack where excessive volumes of information are deliberately sent to a server to slow it down or hinder its functions, effectively preventing legitimate users from accessing the service.
Ways to Minimize Risks:
- Antivirus Software: This is used to prevent, detect, and remove viruses, ensuring the system is protected against malicious attacks.
- Firewalls: Firewalls can be implemented to check and control the inflow of files into the system, preventing harmful files from entering and affecting the system.
