One of the biggest concerns of any cybersecurity analyst is whether or not they will be able to stop an attack before it can do any damage. That said, making sense of the flood of alerts is, in itself, a time-consuming task. As networks become more complex and malicious attacks become more advanced, it can become difficult to hit your incident response targets. With the right network security tools, however, your organization very quickly can detect, prioritize and remediate threats.
Triage: The Key to Improved Incident Response Times
Effective network security begins with triaging each security alert as it comes in. In triage, threats must be prioritized based on risk. Any organization’s network is going to experience a constant influx of alerts about anomalies or potential threats. Many of these will be false positives – they will ultimately be identified as normal, benign activity. Other threats are going to require immediately attention. Identifying the difference between these threat categories, and doing so quickly, is essential.
Triage controls how resources are allocated towards the investigation and remediation of different types of threats. Of course, once threats are detected, they have to be addressed, but there is no organization that has limitless resources. On a practical level, an organization’s team responsible for network and information security is going to need to prioritize its potential issues as effectively as possible.
Many organizations are not set up to properly triage their security alerts. With a number of security solutions, every alert may appear to be of an equal priority level. Older security solutions are also more likely to give off false positives, and these false positives waste time that could be spent on higher priority issues.
When everything is up to an organization’s IT team and analysts, IT professionals need to spend a great deal of their time (Read more...)
