Physical security is the protection of personnel, data, hardware, etc., from physical threats that could harm, damage, or disrupt business operations or impact the confidentiality, integrity, or availability of systems and/or data. Deterrent access control solutions are used to exact consequences in the event of noncompliance. Examples include security badges, mantraps, security cameras, trespass or intrusion alarms, auditing, and firewalls.

A reverse proxy backdoor is a malicious reverse proxy that can intercept and manipulate the traffic between the client and the web server3. This can allow an attacker to access sensitive data or execute commands on the web server.
One possible way to quickly contain the incident with the least amount of impact is to add the application hash to the organization's blocklist. A blocklist is a list of applications or files that are not allowed to run on a system or network. By adding the application hash to the blocklist, the security engineer can prevent the malicious application from running and communicating with the reverse proxy backdoor.
