8 Continuous threat detection

 

This chapter covers

  • Implementation of a continuous monitoring system
  • Using open-source solutions for continuous threat detection
  • The ISCM process
  • Alert threshold lifecycle assessment systems
  • Strategies for continuous monitoring

The ability to detect and respond to threats in real time is critical to cybersecurity. Continuous threat detection is a proactive measure for safeguarding an organization’s data and assets against cyber threats. Phishing attacks and ransomware continuously threaten the cyber landscape. If not detected and addressed promptly, these threats can have severe implications.

This chapter discusses the details of continuous threat detection and offers a guide on how to implement monitoring systems. We will explore using open-source tools like Wazuh (https://www.wazuh.com) to enhance detection capabilities, ensuring that even the most subtle anomalies are identified and addressed. By understanding and applying the right metrics, cybersecurity professionals can better evaluate the effectiveness of their threat detection systems and make better, more informed decisions to bolster their defenses.
