Unfortunately, as a result, this bypasses that robust perimeter protection businesses wanted in the first place. Many IT architectures establish a firewall enhanced with IDS or IPS as a strong perimeter defense.īut, during the pandemic, many companies adopted cloud-based SaaS tools such as Zoom, DropBox, Office 365, or Google Docs that can be accessed directly. For example, if the traffic doesn’t flow through an IPS, it can’t protect that traffic.īut, there are other circumstances as well. While powerful, IDS and IPS solutions do have limitations. Taking it a step further, more advanced solutions use anomaly detection to catch unusual behavior on your network – often enhanced using Artificial Intelligence (AI) or Machine Learning (ML).īoth IDS and IPS solutions can also be deployed as either network-based or host-based solutions.īut, since host-based solutions overlap heavily with endpoint protection, we’ll focus on network-based solutions from here. But, for specifically defined events, IPS’s can also take a pre-defined action.įor example, an IPS might add an external IP address to a firewall blacklist, intercept packets containing malware, or isolate a device from the network – all automatically.Įither way, both technologies can incorporate an antivirus-style signature-based technology to block known attacks. On the other hand, IPS solutions also perform detection. Just like their name implies: they detect intruders. ![]() ![]() Once detected, the IDS solution sends an alert to your security team with details of the event. ![]() IDS options focus on detecting specific events or changes.
