Data breach

A data breach is a cybersecurity incident in which sensitive, confidential, or protected information is accessed, disclosed, altered, or acquired by unauthorized parties. Breaches can result from a wide range of vectors, including sophisticated cyberattacks, exploitation of system vulnerabilities, human error, or malicious insider activity. When a breach occurs, it compromises the confidentiality, integrity, or availability of digital assets, posing significant risks to individuals, organizations, and their operational continuity.

Data breaches are a central concern within risk management frameworks and are closely tied to disciplines such as threat intelligence and incident response. Preventing breaches requires comprehensive security controls, continuous monitoring, and proactive defense strategies. When a breach does occur, organizations must act swiftly to contain the damage, assess the scope of compromise, notify affected parties, and meet regulatory compliance obligations. Effectively understanding and responding to data breaches is essential for safeguarding privacy, maintaining public trust, and ensuring business resilience.
