Study Notes
Confidentiality, Availability, and Integrity
- Confidentiality focuses on protecting personal privacy and proprietary information
- Availability refers to ensuring timely and reliable access to information
- Integrity ensures that information is accurate, complete, and unaltered
Security Breach Levels
- A severe security breach level implies a limited adverse effect on organizational operations
Computer Security
- Computer security is not a simple concept and is difficult to implement
Computer Viruses and Worms
- The primary difference between a computer virus and a computer worm is that a virus needs a host program to replicate, while a worm can replicate independently
- Viruses evade antivirus software through methods such as code obfuscation, polymorphism, and metamorphism
- The spread of a computer virus is often described using the "biological virus" metaphor
- A key method virus writers use to initially infect systems is through exploiting vulnerabilities or using social engineering tactics
- A computer worm does not need a host program because it can replicate and spread without attaching to a program
