- Attack Surface
- The total set of entry points β systems, applications, users, and networks β through which an attacker could gain unauthorized access.
- Control
- A safeguard or countermeasure β technical, administrative, or physical β designed to reduce a specific security risk.
- NIST CSF
- The National Institute of Standards and Technology Cybersecurity Framework, a widely adopted US voluntary standard organizing security activities into five functions: Identify, Protect, Detect, Respond, and Recover.
- Risk Register
- A documented inventory of identified risks, each scored by likelihood and impact, with the assigned owner and planned mitigation action.
- Threat Vector
- The specific path or method an attacker uses to reach a target system β for example, phishing email, unpatched software, or stolen credentials.
- Vulnerability
- A weakness in a system, process, or configuration that a threat actor could exploit to cause harm or gain unauthorized access.
- MFA (Multi-Factor Authentication)
- A login method requiring at least two forms of verification β typically a password plus a one-time code β before granting system access.
- Patch Management
- The process of regularly applying software updates that fix known security vulnerabilities in operating systems and applications.
- Zero Trust
- A security model that requires continuous verification of every user and device β internal or external β rather than trusting anything inside the network perimeter by default.
- RTO / RPO
- Recovery Time Objective (maximum acceptable downtime) and Recovery Point Objective (maximum acceptable data loss window) β the two key metrics that define recovery targets after a disruption.
- Penetration Testing
- A controlled simulated cyberattack performed by authorized security professionals to identify exploitable vulnerabilities before real attackers do.
- Data Classification
- The process of categorizing data by sensitivity level β typically Public, Internal, Confidential, and Restricted β so appropriate controls can be applied to each tier.
