Summary:
Security operations teams often ignore minor alerts, which results in missed threats that evolve into significant breaches, as highlighted by Intezer’s report. Despite managing millions of alerts, endpoints, and cloud data, a traditional severity-based triage means that significant threats, often originating from low-severity alerts, go uninvestigated. An essential finding from the report indicates that approximately 1% of significant breaches stem from alerts initially deemed low severity, which translates to an average of one missed breach per week for most enterprises. Additionally, reliance on traditional endpoint detection and response (EDR) tools proves inadequate since many compromised endpoints labeled as “resolved” still harbor threats. Traditional security operations centers (SOCs) and managed detection and response (MDR) services struggle to scale effectively, often sidelining low-severity alerts, thus failing to catch subtle, evolving threats. However, employing AI-driven triage can enable the investigation of all alerts, ensuring that early-stage threats are caught and detection rules are continuously refined based on comprehensive investigations.
Key Points:
- Nearly 1% of significant confirmed security incidents originate from low-severity alerts, amounting to about one missed breach per week on average in enterprise environments.
- Traditional endpoint security tools often falsely report endpoints as clean despite harboring active infections, as shown by forensic memory scans.
- Phishing attacks have evolved, leveraging trusted platforms and mechanisms, making them harder to detect by standard email gateways.
- Cloud security data reveals attackers’ preference for long-term persistence strategies rather than noisy, high-impact tactics.
- Traditional SOCs and MDRs cannot keep pace with alert volumes, resulting in a significant number of threats remaining uninvestigated due to operational and capacity constraints.
