Threat hunting is a proactive cybersecurity technique that involves searching for indicators of compromise or signs of intrusion within an organization’s network or systems. Unlike automated detection systems, threat hunting is typically carried out by security analysts who use their knowledge and intuition to identify subtle, unusual patterns that may indicate a security breach. The goal of threat hunting is to identify and mitigate threats before they can cause significant damage.

The CBROPS course material covers the concept of threat hunting as part of the skill set required for cybersecurity operations analysts, who are responsible for identifying and mitigating cyber threats

The exhibit shows a Stealthwatch dashboard displaying information on alarming hosts, alarms by type, and today’s alarms. On the left side under “Top Alarming Hosts,” there are five host IP addresses listed with their respective categories indicating different types of alerts including ‘Data Hoarding’ and ‘Exfiltration.’ In “Alarms by Type” section at center top part of image shows bar graphs representing various alarm types including ‘Crypto Violation’ with their respective counts. On right side under “Today’s Alarms,” there’s a table showing the details of each alarm such as the host IP, the alarm type, the severity, and the time. The potential threat identified in this dashboard is that host 10.201.3.149 is receiving almost 19 times more data than is being sent to host 152.46.6.91, which is a sign of data exfiltration. Data exfiltration is the unauthorized transfer of data from a compromised system to an external destination, such as a command and control server or a malicious actor. This can result in data loss, breach of confidentiality, and damage to the organization’s reputation and assets. References := Cisco Cybersecurity Operations Fundamentals - Module 7: Network and Host Forensics

The Zero Trust security model operates on the principle that no one is trusted by default from inside or outside the network, and verification is required from everyone trying to gain access to resources on the network. It emphasizes continuous monitoring, validation, and least-privilege access to minimize exposure to sensitive parts of the network.
