Hook (or other way) to find out when another plugin is activated / installed

Question

Is there some way to run a function when another plugin is being installed and/or activated?

Basically I need something like register_activation_hook only for other plugins.

The use case:

I want to check for CVE patches on my own server when a plugin is installed / activated.

The only thing I can think of right now is manually keeping track of activated and installed plugins, but this is not a very clean solution.

Why can't you use that function? It gets passed to is a plugin file name you can test against - Developer Resources — Howdy_McGee, Commented Apr 8, 2015 at 18:31
Because I don't know what plugins will be activated on the system. Hence I have no way of "binding" plugins by name. — PeeHaa, Commented Apr 8, 2015 at 18:32

I believe you are looking for activated_plugin and deactivated_plugin, see the wordpress documentation:

Wow. Not sure why I didn't find those. That is exactly what I am looking for.

Is there also a thing like that for installation of plugins by any chance?

I don't think so, but you can always get an up to date list of installed plugins via the get_plugins() function. If you're already keeping a running list of activated plugins you can get inactive plugins with something like $inactive_plugins = array_diff(get_plugins(),$active_plugins)
