Description: The ‘Breach Log’ is a critical document used to record and document incidents related to security breaches in computer systems. This log not only details the events that have led to the exposure of sensitive data but also includes information about the nature of the breach, the extent of the damage, the response measures implemented, and the lessons learned. The importance of a breach log lies in its ability to help organizations identify patterns of vulnerability, improve their security protocols, and comply with legal regulations that require the notification of security incidents. Furthermore, this log becomes an essential tool for auditing and risk assessment, allowing organizations to strengthen their security infrastructure and protect critical information from future attacks. In an environment where cyber threats are becoming increasingly sophisticated, maintaining a detailed breach log has become indispensable for information security management and customer trust.
