At one time, everyone considered intrusion detection (IDS) or prevention (IPS) systems critical to overall information security success. But in recent years, observers keep declaring IDS/IPS dead, only to see it keep hanging on. And while we’re still not ready to bury IDS/IPS today, we DO urge you to consider how you’re deploying these tools within your overall information security strategy. Without proper tuning and deployment, IDS/IPS solutions can’t do their jobs properly. And the current landscape of cloud computing and dispersed workforces means protection tied to a firewall misses a lot of activity. Read on to learn how to properly leverage IDS/IPS in a modern environment.
How IDS/IPS Works
The goal of IDS is to detect cyberattacks by analyzing the signature of data packets as they traverse the network. When the system detects a suspicious packet, it generates an alert. IDS is a passive tool that simply detects and alerts. IPS goes a step farther by adding an active protection method of adapting to the threat and blocking the traffic from reaching the intended victim host. Most IDS/IPS solutions are now available as a bundle with your firewall subscription. Read more: https://bit.ly/3uVtJjW
