Threat intelligence is the term for having information about threats and threat actors that helps mitigate harmful events that would otherwise compromise networks or systems. Threat intelligence is the result of collecting, analyzing, and contextualizing data from various sources, such as network traffic, logs, feeds, reports, etc. Threat intelligence provides insights into the tactics, techniques, and procedures (TTPs) of adversaries, as well as their motivations, intentions, and capabilities. Threat intelligence can help organizations to detect, prevent, and respond to cyberattacks, as well as to improve their security posture and resilience12. The other options are not correct, because they are not terms for having information about threats and threat actors. Trusted automated exchange is a concept that refers to the sharing of threat intelligence among trusted entities in a timely and secure manner3. Indicators of Compromise (IoCs) are pieces of forensic data, such as IP addresses, domains, hashes, etc., that indicate a potential intrusion or compromise of a system or network. The Exploit Database is a public repository of exploits and vulnerable software, maintained by Offensive Security. References:
