Security Alerts: Stop the Noise

Security Alerts: #StopTheNoise

Security information and event management (SIEM) alerts are supposed to alert businesses to dangerous advanced attacks. But, according to research provided by Ponemon Institute, organizations waste an average of $1.27 million every year responding to the noise of false alerts.

Of the 17,000 malware alerts an organization receives each week, only 3,230 are considered reliable, and only 680 of the alerts are actually investigated.

Most cyber security solutions don’t distinguish between everyday malware and advanced targeted attacks. Important alerts get lost in the noise of unimportant alerts, allowing attacks to breach network security.

Get best practices to better manage security alerts:

  • Reduce false positives and consolidates related events
  • Verify, analyze, and provide context for alerts
  • Align security to business risks
  • Prioritize and highlight alerts that matter

There is such a thing as too much security. The alerts generated by SIEM are supposed to help protect businesses from cyber attacks. But the sheer volume of those alerts often undermines their purpose.

According to recent research, organizations can receive nearly 17,000 alerts per week.

  • More than 33% are duplicate alerts
  • More than 51% are false positives
  • 19% of the alerts are considered reliable
  • 4% of the alerts are actually investigated

It costs millions of dollars a year to process all those alerts. What’s worse is that SIEMs don’t differentiate between everyday malware and advanced attacks. Higher priority indicators of advanced attacks get lost in the noise of low priority alerts.

Advanced attacks can easily slip through the cracks, breaching critical network systems.

The answer isn’t simply more cyber security. It’s better cyber security that emphasizes quality over quantity.

Better cyber security helps automate and optimize alert processing. Security teams should spend less time reviewing false positives and duplicate alerts. Ideally, the security solution should verify, analyze, and prioritize alerts. It should also add sufficient contextual intelligence to priority alerts so that security teams can respond promptly and appropriately.

Detecting attacks is important. But detecting attacks while generating a large number of false positives is about as effective as not detecting attacks at all."
