Recommendations
Apply appropriate updates provided by Zoom or other vendors which use this software to vulnerable systems immediately after appropriate testing.
Apply the Principle of Least Privilege to all systems and services. Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
Use vulnerability scanning to find potentially exploitable software vulnerabilities to remediate them.
Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information. Use a DMZ to contain any internet-facing services that should not be exposed from the internal network. Configure separate virtual private cloud (VPC) instances to isolate critical cloud systems.
Use capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring.
