Access Control: Mechanisms to restrict unauthorized users from accessing certain systems or data. Examples include passwords, biometrics, and security tokens.

Authentication: The process of verifying the identity of a user, device, or system, typically through passwords, biometric data, or security tokens.

Authorization: The process of granting or denying access rights to a user or system based on their authenticated identity and role.

Backup: The process of creating copies of data to ensure its recovery in case of data loss or corruption.

Breach: An incident where unauthorized individuals gain access to confidential data or systems.

Compliance: Adherence to laws, regulations, and guidelines set by governing bodies or industry standards to ensure proper data protection and privacy.

Data Encryption: The process of converting data into a coded format to prevent unauthorized access. Encrypted data can only be read or processed by those with the decryption key.

Firewall: A network security system designed to monitor and control incoming and outgoing network traffic based on predetermined security rules.

Incident Response: The process of detecting, responding to, and recovering from cybersecurity incidents or breaches.

Intrusion Detection System (IDS): A device or software application that monitors network or system activities for malicious activities or policy violations.

Intrusion Prevention System (IPS): Similar to an IDS, but with the added capability to block or prevent detected malicious activities.

Malware: Malicious software designed to damage, disrupt, or gain unauthorized access to computer systems. Types include viruses, worms, and ransomware.

Penetration Testing: A simulated cyber attack on a system to identify and address vulnerabilities before malicious hackers can exploit them.

Phishing: A fraudulent attempt to obtain sensitive information by disguising oneself as a trustworthy entity in electronic communications.

Regulations: Rules or laws established by authorities to govern practices in specific industries, such as GDPR, HIPAA, or PCI-DSS.

Risk Assessment: The process of identifying, evaluating, and prioritizing risks to an organization's information assets and determining appropriate mitigation strategies.

Security Policy: A set of guidelines and procedures that define how an organization manages and protects its information assets.

Threat: Any potential danger that could exploit a vulnerability and cause harm to a system or data.

Vulnerability: A weakness or flaw in a system that could be exploited by threats to gain unauthorized access or cause damage.

Virtual Private Network (VPN): A secure network connection that encrypts data transmitted over public networks to ensure privacy and security.

Two-Factor Authentication (2FA): An additional layer of security that requires users to provide two forms of verification (e.g., a password and a code sent to a mobile device) before gaining access to a system.

Zero Trust Security: A security model that assumes no implicit trust for any user or device, whether inside or outside the network, and requires continuous verification before granting access.

This glossary covers fundamental terms in cybersecurity and compliance, providing a solid foundation for understanding the field.
