Most of the CTI programs prove inefficient, making effective operationalization of threat intelligence difficult. Some of the reasons why an organization’s CTI program fails can be:
Legacy tools fail to ingest or add context to data generated by internal sources. With several internally deployed security tools, it’s important for SecOps teams to leverage the threat intel generated by them. SecOps teams need to put in place CTI programs that allow them to harness internal threat intel.
Security teams often switch between different consoles to manage threat intel and analysis data, perform detailed investigations, and configure threat protection policies. These SOC silos and lack of centralized visibility increase complexity and redundant tasks in security administration. A CTI program is inadequate if it doesn’t provide a holistic view of an organization’s security posture and prevents security teams from performing investigations from a single unified console.
There exist a wide range of threat intelligence solutions that ingest IOCs from disparate sources. However, not all of them are capable of IOC advanced enrichment and threat correlation. Consequently, security teams struggle to calculate the confidence score of the IOCs, thereby failing to take necessary action on potential threats. As part of their CTI programs, organizations must employ a connected threat intelligence platform (TIP) that helps security teams to correlate threat data with additional context and assign confidence scores to threat indicators. Besides correlating threat data, connected TIPs have the capability to integrate with several tools to correlate new intelligence with historical data as well as network and endpoint activity to gain threat visibility. An organization’s CTI program proves to be inefficient if it doesn't focus on threat correlation.
