Which action should be performed to resolve communication issues with CrowdStrike endpoints?

To resolve communication issues with CrowdStrike endpoints, allowing the CrowdStrike endpoints through the network is essential. By implementing an allowlist for these endpoints, you ensure that the necessary traffic can flow freely without being interrupted or blocked by firewalls or other network security measures. This allows the CrowdStrike software to effectively communicate with the CrowdStrike cloud and send telemetry data back and forth, which is crucial for maintaining security and real-time threat detection.

Additionally, while options such as blocking all other network traffic, using only a private subnet, or disabling network security protocols may seem like potential solutions, they would likely introduce more issues than they resolve. Blocking all other traffic could prevent necessary internet-based communications, limiting the capability of not just CrowdStrike, but potentially other critical services. Utilizing a private subnet only would restrict access to external communication, which is contrary to how CrowdStrike operates effectively. Disabling all network security protocols could expose the network to vulnerabilities, contradicting the very purpose of implementing endpoint security measures.
