Think of notifications as general information about events sent to a receiving platform or team for further assessment if needed. They communicate information about unremarkable changes and behaviors in an IT environment. Generally, notifications do not represent risks or anomalies in a system and don’t require immediate attention.
Alerts, however, do require urgent action from a security team. These are special notifications that deliver information about a warning/critical event or a developing incident. The purpose of alerts is to call to attention actions that are close to or have already passed pre-established security rules, profiles, or thresholds. Warnings/critical events and incidents trigger alerts so that the information is relayed quickly to the responsible party for immediate assessment, communication, and action.
Alerts are a crucial element during incident response as they can cut down response time. Most issues, when detected early enough, can be detained and removed from a system before threat actors can even launch their attack or exfiltrate sensitive information. Also, they allow for a smoother communication flow between the security team and the client so that any critical decision making can be carried out in a timely manner.
Avoiding alert fatigue
It is important that you work closely with your clients to establish appropriate thresholds for alerting on events and incidents. For example, alerts can be expanded to include detailed information about events, or they can be filtered and suppressed if deemed repetitive or redundant. Alert fatigue occurs when thresholds are set too low. In this scenario, security teams must spend time cutting through the noise and weeding out false positives.
Alert fatigue can also cause teams to miss early indicators of threats or lose out on valuable warning time needed to take preventative measures or escalate. To combat this risk, more MSPs are leveraging Managed Detection & Response (MDR) services which provide actionable alerts in real-time to close the gap between the earliest discovery of threat and an impending attack.
