Threat intelligence, also known as cyber threat intelligence (CTI), is information gathered from a range of sources about current or potential attacks against an organization. The information is analyzed, refined and organized and then used to minimize and mitigate cybersecurity risks.
The main purpose of threat intelligence is to show organizations the various risks they face from external threats, such as zero-day threats and advanced persistent threats (APTs). Threat intelligence includes in-depth information and context about specific threats, such as who is attacking, their capabilities and motivation, and the indicators of compromise (IOCs). With this information, organizations can make informed decisions about how to defend against the most damaging attacks.
Why is Cyber threat intelligence important?
In a military, business or security context, intelligence is information that provides an organization with decision support and possibly a strategic advantage. Threat intelligence is a part of a bigger security intelligence strategy. It includes information related to protecting an organization from external and inside threats, as well as the processes, policies and tools used to gather and analyze that information.
Threat intelligence provides better insight into the threat landscape and threat actors, along with their latest tactics, techniques and procedures. It enables organizations to be proactive in configuring its security controls to detect and prevent advanced attacks and zero-day threats. Many of these adjustments can be automated so security stays aligned with the latest intelligence in real time.
