It is hardly reassuring for a security team to reject a credible attack warning without giving it due weight. However, this risk is amplified by an excess of false alarms and false alerts, which can lead to alert fatigue. Every security tool designed for attack detection will inevitably make mistakes. For decades, researchers and vendors have worked to improve the accuracy of threat detection without compromising performance. Identifying attacks requires a constant trade-off between false negatives, when a tool misses a real attack, and false positives, when a tool flags benign activity as malicious. Methods that reduce false alarms typically result in more false positives. When this balance is disrupted, false positives can impair the effectiveness of the security team. Cybersecurity solutions that can generate false alarms in threat detection include anti-malware, anti-phishing, SIEM, Intrusion Detection and Prevention Systems, DLP, firewalls, and EDR. Security managers must know how frequently their security tools generate false alarms.
