    Study Notes

    • Computer security is about protecting data in a computer from unauthorized access.

    • Confidentiality, integrity, and availability are the main aspects of computer security.

    • Confidentiality ensures that only authorized parties access computer assets.

    • Integrity ensures that assets can only be modified by authorized parties or in authorized ways.

    • Availability ensures that assets are accessible to authorized parties at appropriate times.

    • Vulnerabilities are weaknesses in the security system that can be exploited.

    • Threats are circumstances that have the potential to cause loss or harm to a computing system.

    • Attacks are the exploitation of vulnerabilities by humans or other systems.

    • Information security and traditional security differ in that information can be stolen but not lost, and confidential information can be copied and sold without detection.

    • Security deals with the protection of assets through prevention, detection, and re-action.

    • Viruses are malicious software programs that can infect computers and spread to others.

    • Worms are more sophisticated viruses that can replicate and send themselves to other computers.

    • Trojan horses and logic bombs are types of malware that can damage systems and steal data.

    • Social engineering is the manipulation of people into performing actions or divulging confidential information.

    • Phishing uses fake emails to trick people into giving away sensitive information.

    • Pharming uses fake websites to gather login credentials.

    • Botnets are networks of compromised computers used to send spam or launch attacks.

    • Rootkits are collections of programs used to mask intrusions and obtain administrator-level access to computers.
