What does a threat intelligence analyst do?

A threat intelligence analyst is responsible for identifying, analyzing, and interpreting potential security threats to an organization's information systems and networks. They gather data from various sources, such as security logs, network traffic, and external threat feeds, to understand the tactics, techniques, and procedures (TTPs) used by threat actors.

Key responsibilities include:

1. Monitoring and analyzing security event logs and network traffic to detect anomalies or indicators of compromise.
2. Conducting in-depth investigations into potential security incidents to determine the scope and impact.
3. Developing and maintaining threat intelligence reports and dashboards to communicate findings to stakeholders.
4. Collaborating with other security teams to implement appropriate countermeasures and mitigate identified risks.
5. Staying up-to-date with emerging threats and vulnerabilities to proactively enhance the organization's security posture.

Example: A threat intelligence analyst might identify a new malware campaign targeting a specific industry sector. They would analyze the malware's behavior, determine its origin, and assess the potential impact on their organization. Based on this analysis, they would recommend implementing specific security controls, such as updating firewalls or deploying new intrusion detection rules, to protect against the threat.

In the context of cloud computing, threat intelligence analysts can leverage services like Tencent Cloud's Security Information and Event Management (SIEM) to aggregate and analyze security data from various sources, helping to identify and respond to threats more effectively.
