It covers a wide range of security areas, including access control, incident response, and system and communications protection. It is widely adopted by government agencies and contractors.

COBIT (Control Objectives for Information and Related Technologies).

COBIT is a framework developed by ISACA (Information Systems Audit and Control Association) for governing and managing enterprise IT. While not exclusively focused on cybersecurity, COBIT helps organizations align IT with business objectives, manage risks, and ensure compliance with regulations and standards. COBIT provides a set of processes and controls covering various domains, including information security, risk management, and governance. The framework is particularly useful for organizations concerned with regulatory compliance.

Payment Card Industry Data Security Standard (PCI DSS).

Developed by the Payment Card Industry Security Standards Council (PCI SSC), PCI DSS is a set of security standards designed to ensure the secure handling of credit card information. It applies to organizations that store, process, or transmit cardholder data. The standard includes requirements for network security, access control, encryption, and regular testing of security systems to prevent credit card fraud and data breaches. PCI DSS compliance is mandatory for organizations that manage payment card data.

FISMA (Federal Information Security Management Act).

FISMA is a United States federal law that establishes cybersecurity requirements for federal agencies and their contractors. It outlines a framework for developing, implementing, and managing information security programs based on NIST standards within the federal government.

FAIR (Factor Analysis of Information Risk).

FAIR is a risk management framework that focuses on quantifying and analyzing information security risks. It provides a model for understanding, analyzing, and measuring information risk in financial terms. FAIR is often used in conjunction with other frameworks and standards.

Capability Maturity Model Integration (CMMI).

While not exclusively a cybersecurity framework, CMMI is a framework that provides guidance for improving processes in software development and other areas of an organization. It defines maturity levels that indicate the organization’s capability to manage and continuously improve its processes. CMMI helps organizations streamline processes, improve quality, and achieve greater efficiency and effectiveness.

Cybersecurity Maturity Model Certification (CMMC).

CMMC is a cybersecurity framework developed by the US Department of Defense (DoD) to enhance the cybersecurity posture of defense contractors and subcontractors. CMMC aims to ensure that defense contractors have adequate cybersecurity measures in place to protect controlled unclassified information (CUI). It consists of five maturity levels ranging from basic cybersecurity hygiene to advanced practices, each with specific cybersecurity practices and processes. CMMC requires contractors to demonstrate compliance with specific cybersecurity practices to bid on DoD contracts.

MITRE ATT&CK (Adversarial Tactics, Techniques, and Common Knowledge).

ATT&CK is a knowledge base developed by MITRE that provides information on the tactics, techniques, and procedures used by adversaries during cyber-attacks. It is not a framework for implementation but is widely used for threat intelligence, red teaming, and improving detection and response capabilities.

Health Insurance Portability and Accountability Act (HIPAA).

The Health Insurance Portability and Accountability Act (HIPAA) is a US federal law that sets standards for the protection of sensitive patient health information (PHI). It aims to ensure the confidentiality, integrity, and availability of PHI and mandates safeguards such as access controls, encryption, and audits to protect against unauthorized access, use, or disclosure. HIPAA applies to healthcare providers, health plans, healthcare clearinghouses, as well as their business associates.
