Study Notes

Understanding Computer Security: Key Concepts and Terms

The NIST Computer Security Handbook defines computer security as the protection of automated information systems to achieve the objectives of preserving confidentiality, integrity, and availability.
Confidentiality refers to the assurance that private or confidential information is not disclosed to unauthorized individuals, while privacy ensures individual control over collected information.
Integrity covers data and system integrity, which assure that information and programs are changed only in an authorized manner and that a system performs its intended function free from manipulation.
Availability ensures that systems work promptly, and service is not denied to authorized users.
Computer security is a process that involves hardware, software, and people, and it focuses on balancing protection of confidentiality, integrity, and availability while maintaining efficient policy implementation.
Cyber attacks are aimed at making one or more security pillars ineffective, and they can target users or carriers of an asset, causing direct damage.
Active attacks attempt to alter system resources, while passive attacks attempt to learn or use information from the system without affecting resources.
Inside attacks are initiated by an entity inside the security perimeter, while outside attacks are initiated by unauthorized or illegitimate users outside the perimeter.
A countermeasure is any means taken to deal with a security attack, and it can prevent or detect and recover from the effects of an attack.
An asset is the set of components within a perimeter, while an attack surface refers to the surface that can be potentially used by attackers, including hardware, software, and network components.
Early computer security problems included moths found in a Navy computer and tone-producing "blue boxes" used to make free phone calls, which were later replaced by Cap'n Crunch cereal box whistles.
Understanding computer security requires a structured approach, such as the MITRE ATT&CK framework, that describes how attacks can be conducted and how countermeasures can be put in place.
