Is this always possible using systemextensionsctl by root? Is there a way to prevent root from removing an Endpoint Security Extension? The use case is for a Mac managed by AirWatch.

I am using SFAuthorizationPluginView in my Security agent plugin. My code expects that its willActivate method be called. With normal screensaver unlock, this works fine. However if I enter an invalid password, then enter the correct password, I never get the willActivate call. I have reproduced this with Quinn's LoginUIAuthPlugin from the QAuthPlugins example code. My mechanisms look like this with LoginUIAuthPlugin: mechanisms HyprAuthPlugin:invoke builtin:authenticate,privileged PKINITMechanism:auth,privileged LoginUIAuthPlugin:login CryptoTokenKit:login I would like to be able to get my plugin working properly when the user had previously entered an invalid password.

Since this file is protected by SIP, it can't just be changed by an installer/app without prompting the user. If the user chooses to deny the request, the sudo file won't be updated with a security critical pam module. I need to insert our custom pam module into /etc/pam.d/sudo without the user being able to deny the operation.

There does not seem to be a way to code sign a PAM module so that an XPC service can verify the signature with setCodeSigningRequirement. There should be a way to build a PAM module (dynamic Library ) so it can be code signed. Put in a bundle and code signing the bundle does not work .

I've tried getting LAContext and checking it, but it says it canEvaluatePolicy returns false for any biometric policy.

I have a security agent plugin that uses NSXPCConnection to communicate with a launch daemon. This works well, but I want to make sure the launch daemon has not been compromised. I added code to call setCodeSigningRequirement in my module that handles the client side of the NSXPCConnection. However, when used in the security agent plugin, remoteObjectProxyWithErrorHandler reports an error NSCocoaErrorDomain Code=4102 "The code signature requirement failed." If I call my xpc module from a test application, I do not receive an error and everything works as expected. I have tried different code signing requirements. Even with just "anchor apple generic" I still get the error. The console log shows two entries of interest com.apple.SecurityAgentHelper.arm64 default 09:13:29.677567-0500 SecurityAgentHelper-arm64 EOGSecurityServiceClient biometricAuthorization remote proxy error: Error Domain=NSCocoaErrorDomain Code=4102 "The code signature requirement failed." UserInfo={NSDebugDescription=The code signature requirement failed.}

Issue happens with system.login.screensaver. After my SFAuthorizationPluginView sets a result allowing login, my view remains on screen for about eight seconds. What makes my view disappear? I notice that my plugin mechanism just gets a destroy call.

Due to some challenging corporate network firewall, security filters and certificate management, I would like to implement a TLS server where it initiates the TCP connection to the client side so that once TCP is connected, the client side sends its Client Hello message. Everything then continues as expected. The connection would use Bonjour to locate the TLS client endpoint that is hosted on iOS. The TLS server will be hosted on MacOS. Swapping the normal tcp listener as TLS server will help with certificate management as the Mac will have the server cert installed and the iOS device will have the client cert installed.
