A SOC analyst receives an alert from the SIEM indicating a possible data exfiltration attempt. Before escalating, the analyst wants to enrich the alert with threat intelligence to determine if the source IP is malicious. Which type of threat intelligence feed should the analyst consult first to quickly assess the reputation of the IP address?
Trap 1: Tactical threat intelligence
Tactical threat intelligence involves specific indicators of compromise (IOCs) such as IP addresses, domains, and file hashes. It is closer to what the analyst needs, but the term often refers to the collection and sharing of IOCs. However, the most direct and commonly used feed for IP reputation is a threat intelligence platform that aggregates tactical data. Among the options, tactical is not the best fit because it is a broader category, and the scenario asks for the first feed to consult for reputation.
Trap 2: Strategic threat intelligence
Strategic threat intelligence provides high-level, long-term insights about threat actors and geopolitical trends, not real-time IP reputation. It is used for executive decision-making and planning, not for immediate alert triage. In this scenario, the analyst needs actionable, technical data about a specific IP, so strategic intelligence would not provide the quick assessment required.
Trap 3: Operational threat intelligence
Operational threat intelligence focuses on details of specific attacks, including tools, techniques, and procedures (TTPs) used by threat actors. While it can help understand an attacker's methods, it does not typically provide a simple reputation score for an IP address. The analyst needs immediate, actionable data to decide whether to escalate, so operational intelligence is less suitable here.

Technical threat intelligence
Technical threat intelligence provides immediate, machine-readable data about specific indicators like IP addresses, domains, and file hashes, often including reputation scores. In this scenario, the analyst needs to quickly determine if the source IP is malicious, so consulting a technical threat intelligence feed (e.g., a threat intelligence platform with IP reputation) is the most direct and efficient action. This aligns with the need for rapid enrichment during alert triage.
