Risk-Based Alerting – Shift from SIEM To Superior Risk-Based Alerting.

Security Information and Event Management (SIEM) has been a cornerstone of cybersecurity for years, helping organizations detect, analyze, and respond to security threats before they disrupt business operations. However, as cyber threats evolve, so too must our defenses. Enter Risk-Based Alerting (RBA), a new frontier in cybersecurity that promises to revolutionize how we handle security alerts.

SIEM in a nutshell

Security Information and Event Management (SIEM) is like a security guard for your computer systems. It helps find and stop security threats. It collects data from various sources in your IT environment, such as user activities, server events, and network traffic. It then analyzes this data to identify anything unusual that might indicate a security threat. But as threats get smarter, we need to get smarter too. That’s where Risk-Based Alerting (RBA) comes in.

What is Risk-Based Alerting?

Risk-Based Alerting is an approach where security alerts and responses are prioritized based on the level of risk they pose to an organization’s systems, data, and overall security posture. This method enables organizations to concentrate their resources on addressing the most critical threats first.

In other words, Risk-Based Alerting is like a smarter security guard. It decides which security alerts are most important based on how much risk they pose. This means we can focus on the most dangerous threats first.

The Problems with SIEM

Traditional SIEM systems collect event log data from a range of sources, identify activity that deviates from the norm with real-time analysis, and take appropriate action. However, SIEM systems often generate a high volume of alerts, many of which may be false positives or minor issues. This can lead to alert fatigue, where security teams become overwhelmed and may overlook critical alerts.

In simple words, the old security guard, SIEM, collects data and looks for anything unusual. But it often raises too many alarms, even for small issues. This can make it hard to see the really important alerts.

The Advantages of Risk-Based Alerting

In contrast to SIEM, RBA offers several advantages:

1. Efficient Resource Allocation: By prioritizing alerts based on risk, organizations can allocate their resources more efficiently. We can focus our efforts on the most dangerous threats.
2. Reduced Alert Fatigue: RBA helps reduce alert fatigue by allowing teams to focus on alerts with the greatest potential impact. Which means, we won’t be bombarded with too many alerts.
3. Better Decision-Making: Prioritizing alerts based on risk enables better decision-making. Translating to making better decisions about which threats to tackle first.
4. Integration of Threat Intelligence: It promotes the integration of threat intelligence into the decision-making process. We can use information about threats to make better decisions.

How Network Detection and Response Helps in Risk-Based Alerts.

Network Detection and Response (NDR) plays a key role in facilitating the implementation of risk-based alerts within an organization’s cybersecurity strategy. NDR solutions are designed to detect and respond to threats on your network and provide insights into the potential risks of various activities or incidents.

Basically, Network Detection and Response (NDR) is a tool that helps us implement risk-based alerts. It helps find and respond to threats on your network and gives us information about potential risks.

Examples of Risk-Based Alerting

One example of RBA in action is an unauthorized access attempt. An external IP address attempts to gain unauthorized access to a critical server. The risk factors include the affected asset, which is a critical server containing sensitive customer data, and anomalous behavior, such as the IP address having no prior history of accessing this server. As a result, the risk score is high.

In simple terms, if someone tries to access a server that they shouldn’t, the risk-based alert system would raise a high-level alert. This is because the server contains important data, and the person trying to access it is behaving suspiciously. This is Risk Based Alerting Simplified.

Conclusion

Risk-Based Alerting represents a significant advancement in cybersecurity, offering a more efficient and effective approach to threat detection and response. By prioritizing alerts based on risk, RBA enables organizations to better allocate resources, reduce alert fatigue, and make more informed decisions about potential threats. As cyber threats continue to evolve, so too must our defenses. Risk-Based Alerting is a step in the right direction, offering a more adaptive and proactive approach to cybersecurity.

Which means as threats continue to get smarter, we need to stay one step ahead. Risk-Based Alerting helps us do that. Stay safe!
