When I blocked the content of this site things were ok for a while then I was redirected to something called Jokeroo. First, I was redirected to a Chinese Sex Museum site. I have my own website and have recently been having redirection problems. For more information on Falcon, see the additional resources and links below.I hope someone can help me. Network containment is a fast and powerful tool that is designed to give the security admin the power needed to identify threats and stop them. Again if the change doesn’t happen within a few seconds the host may be off line. The previous status will change from “Lift Containment Pending” to “Normal” (a refresh may be required). Once the host is selected you’ll see that the status is contained (see previous screenshot) and click on the “Status: Contained” button. Locate the contained host or filter hosts based on “Contained” at the top of the screen. Since a connection between the Falcon Sensor and the Cloud are still permitted, “un-contain” is accomplished through the Falcon UI. If containment is pending the system may currently be off line.Īfter investigation and remediation of the potential threat, it is easy to bring the device back online. Containment should be complete within a few seconds. The Hosts app will open to verify that the host is either in progress or has been contained. To verify that the host has been contained select the hosts icon next to the Network Contain button. The dialogue box will close and take you back to the previous detections window. Selecting the “Network Contain” will open a dialogue box with a summary of the changes you are about to make and an area to add comments.Īfter information is entered, select Confirm. To prevent this movement and contain this system from the network, select the “Network Contain this machine” option near the top of the page. Drilling into the process tree, we can see that reconnaissance was performed and credential theft occured, possibly in an attempt for lateral movement. Doing so will provide more details and allow you to take immediate action.Īfter drilling into the alert, we can see multiple detection patterns, including known malware, credential theft and web exploit. To get more detail, select any of the lines where an alert is indicated. In our Activity App, we see a system that has multiple detections in a short amount of time, and it can quickly be ascertained that action should be taken. Often times, network containment is necessary when a system appears infected and lateral movement, persistence and exfiltration want to be prevented, among other risks. In the Falcon UI, navigate to the Detections App. Identify and contain a compromised system When systems are contained, they will lose the ability to make network connections to anything other than the CrowdStrike cloud infrastructure and any internal IP addresses that have been specified in the Respond App. Network Containment is available for supported Windows, MacOS, and Linux operating systems.
