Breach detection is the process of identifying and responding to unauthorised access or activity on a computer system or network. It is an essential component of a comprehensive cybersecurity strategy, as it allows organisations to identify and respond to potential threats in a timely manner.

There are several methods that organisations can use to detect breaches, including:

• Network monitoring: This involves monitoring network traffic for unusual patterns or activities that may indicate a breach.
  
• Intrusion detection and prevention systems (IDPS): These systems use algorithms and rules to detect and prevent unauthorised access to a system.
  
• Log monitoring: Organisations can use log monitoring software to review system logs for suspicious activity, such as failed login attempts or unexpected changes to system files.
  
• Endpoint security: This involves installing security software on individual devices, such as laptops and smartphones, to monitor and protect against potential threats.
  

Effective breach detection requires a combination of people, processes, and technology. Organisations should have a clear plan in place for responding to potential breaches, including procedures for alerting appropriate personnel and taking appropriate actions to minimise the impact of the breach.

Overall, breach detection is a crucial element of cybersecurity, as it allows organisations to identify and respond to potential threats in a timely manner and minimise the impact of a breach on their systems and data.
