In its Fourth Annual Report on the State of SIEM Detection Danger, CardinalOps, an AI-powered safety engineering startup, discovered that Safety Data and Occasion Administration (SIEM) instruments include big blind spots, compromising the flexibility of an enterprise to detect cyber threats.
The report analyzed real-world information from manufacturing SIEM cases to realize a greater understanding of the present state of use case growth and menace detection protection throughout enterprise SOCs. The manufacturing SIEMs analyzed within the report included IBM QRadar, Sumo Logic, Microsoft Sentinel, and Splunk.
Analyzing real-world information from manufacturing SIEMs overlaying 3000 detection guidelines throughout various {industry} verticals and 1.2 million log sources from main SIEMS, the examine discovered that the instruments solely lined 19% of the MITRE ATT&CK strategies.
In keeping with CaridinalOps, the information that’s collected by the SIEM instruments may probably cowl as much as 87% of all assault strategies, so it isn’t an information drawback. Enterprises have entry to all the information they should reduce the assault floor. Nonetheless, enterprises have been unable to make use of this information to enhance menace detection.
“These findings spotlight the problem that organizations face in constructing and sustaining efficient detection protection,” stated Yair Manor, CTO and Co-Founder at CardinalOps. “Safety groups proceed to battle with getting probably the most out of their SIEM and worse, usually falsely imagine that they’re protected when in actuality they’re at nice danger.”

The MITRE ATT&CK, which was used as a baseline for this examine, is an industry-standard framework for understanding adversary playbooks and conduct. The newest MITRE ATT&CK framework covers 201 strategies, however the enterprise SIEMs examined on this examine have detections for less than 38 of them.
Primarily based on the SIEM guidelines analyzed within the report, practically 1 in 5 SIEM guidelines are damaged resulting from points akin to lacking fields or misconfigured information sources. Which means these SIEM guidelines gained’t set off safety alerts, leaving attainable threats undetected.
The info from the CardinalOps examine exhibits that the typical enterprise has over 130 totally different safety instruments starting from endpoint options to e mail authorizations. A number of SIEM environments are on the rise, with greater than 2 in 5 enterprises having two or extra SIEM instruments in manufacturing.
The complexity of utilizing a number of instruments might be one purpose for the hole between the anticipated protection and the precise protection. In keeping with CardinalOP’s evaluation of the report information, having a large number of safety instruments could make it more difficult to maintain monitor of every device’s alerts, occasion sorts, and log codecs, that are important to ascertain distinctive detection for every.

The findings of the report additionally spotlight that on the subject of SIEM detections, there isn’t any commonplace or common method that works for all enterprises. Each group has its distinctive traits and this influences how the SIEM instruments have to be configured and used.
The traits that have to be thought of embrace info know-how environments, group constructions, regulatory necessities, and the group’s distinctive SIEM processes. Customization is essential for maximizing the effectiveness of the instruments and bettering the general cybersecurity posture.
The CardinalOps report highlights that the hole between SIEM instruments’ capabilities and the precise protection is a crucial subject within the cybersecurity panorama. Whereas SIEM instruments supply glorious versatility, there’s a want for specialised instruments, akin to SaaS Safety Posture Administration and Cloud Safety Posture Administration. These instruments can assist an enterprise deal with the distinctive cybersecurity challenges of their particular setting.
