- Security policy: A security policy is a set of rules and guidelines that define how an organization will protect its information assets and resources. It outlines the goals, objectives, and procedures for ensuring the confidentiality, integrity, and availability of information.
- Countermeasure: A countermeasure is a measure or action taken to prevent or mitigate a security threat or attack. It is designed to reduce the risk or impact of an attack and protect the system or network from vulnerabilities.
- Vulnerability: A vulnerability is a weakness or flaw in a system or network that can be exploited by an attacker to gain unauthorized access, disrupt operations, or cause damage. It can be a software bug, misconfiguration, or a design flaw that can be exploited.
- Attacks: Attacks refer to deliberate actions or techniques used by threat agents to exploit vulnerabilities and compromise the security of a system or network. Examples include malware infections, denial-of-service attacks, phishing, and social engineering.
- Threats: Threats are potential dangers or risks that can exploit vulnerabilities and cause harm to a system or network. They can be natural disasters, human errors, malicious attacks, or any other event that can compromise the security of information.
- Risk: Risk is the potential for loss, damage, or harm resulting from a vulnerability being exploited by a threat. It is the likelihood of a threat agent exploiting a vulnerability and the impact it would have on the system or organization.
- Threat agent: A threat agent is an entity or individual that carries out or poses a threat to a system or network. It can be a hacker, a malicious insider, a virus, or any other entity that can exploit vulnerabilities and cause harm.
- Authenticity: Authenticity refers to the assurance that data, information, or communication is genuine, accurate, and trustworthy. It ensures that the sender and receiver of information can verify each other's identity and that the data has not been tampered with or altered.
- Non-repudiation: Non-repudiation is the ability to prove the integrity and origin of a message or transaction, preventing the sender from denying their involvement or the validity of the communication. It ensures that the sender cannot later deny sending the message or performing the action.
- System resource: System resources refer to the hardware, software, and network components that are utilized by a system or network to perform tasks and provide services. Examples include servers, routers, databases, storage devices, and processing power.
