Who is a Cyber Threat Intelligence Analyst?
A cyber threat intelligence analyst is a security personnel whose task is to monitor, collect, and analyze external threat data to help organizations with actionable threat intelligence. These security experts are also known as CTI analysts, who assess all the data collected from different sources and understand the pattern of attack and motive behind the threat.
Then, they process all the data to create threat intelligence feeds and provide actionable reports to the security teams and other stakeholders. These analysts leverage their knowledge and experience on malicious software and other security tools to accurately identify, measure, and counter potential security threats.
These individuals not only closely monitor indicators of compromise but also assist teams in taking necessary steps to secure assets that need immediate protection. Rather than making a generalized report, analysts prioritize threats and focus on the one that can make the most impact. Besides gathering data and analyzing threats, cyber threat intelligence analysts also provide recommendations on mitigation processes and future security strategies.
Types of Threat Intelligence
Threat intelligence empowers organizations with critical data regarding potential as well as existing threats.
However, every organization has its specific intelligence data requirement, and it can use simple threat data regarding a malware variant or complex data regarding a malicious actor’s motive and processes. Due to varying requirements, threat intelligence is categorized into four different types:
Operational Threat Intelligence
Operation threat intelligence is all about tracking and focusing on tools and methodologies that attackers utilize to carry out a successful attack. It enables analysts to identify threat campaigns and understand the nature, motive, timing, and process of an attack.
Unlike others, operational intelligence requires a lot of resources, and they have immense usability because attackers don’t easily shift from existing TTPs, leading to longer usable life. Usually, the information is sourced from adversaries’s chat rooms or community discussions. From SOC, incident response, and threat monitoring to vulnerability, operational threat intelligence is suitable for many cybersecurity domains.
Strategic Threat Intelligence
On the other hand, strategic threat intelligence gives every organization an overview of its cyber threat landscape. This intelligence is mainly meant for executive-level professionals who need to understand the organization’s threat posture for the organization’s strategic planning.
It provides executives with insight into vulnerabilities, potential risks, and other threats along with attackers profiling, goal, and severity of the attack. It is considered hardest to generate as intelligence gathering requires human data collection and assessment with intricate knowledge about cybersecurity.
Besides, strategic intelligence also provides an overview of how global events, international activity, foreign policies, and other events can impact the cybersecurity of an organization.
Tactical Threat Intelligence
Tactical threat intelligence mainly focuses on detecting specific malware types and details of attackers’ TTP through indicators of compromise. The details generated by this threat intelligence are mainly consumed by cybersecurity solutions and security teams to detect and mitigate potential threats.
The organization utilizes intelligence to build its defense strategy and remove vulnerabilities in the network that attackers can take advantage of. This threat intelligence is easiest to generate, and most of the time, the process is automated.
However, the lifespan of the data is short because IOCs can become obsolete within days or hours. The biggest challenge is finding the right source to generate data and minimize false positives.
Technical Threat Intelligence
It is a specialized type of threat intelligence that emphasizes specific evidence of a threat or incident and provides a base for a thorough investigation. The analysts assess the evidence for indicators of compromise that encompasses phishing email contents, malware samples, malicious URLs, and quarantined IP addresses.
The analysts have to be quick in their investigation and share them with the stakeholders because IOCs have a very short lifespan. The data are hard to get as technical threat intelligence looks for certain evidence in an attack. It is quite different from operational threat intelligence as it is adaptable and allows analysts to adjust their tactics.
