How to check if screen lock is enabled in the settings using adb

I need to know how to check if any type of screen lock is enabled in the settings part of the device. I need to check this using an adb command (by using adb shell). I also need to know the type of lock applied.

I have tried dumpsys but did not get any success.

I want to know if the screen lock is enabled in the settings even if the device is currently unlocked, just check if any security is there, in any state.
