1. A system for capturing, using a gatekeeper device, a Remote Desktop Protocol (RDP) session, comprising:

a set of one or more processors configured to, using a set of one or more interfaces:

receive an indication that the session should be captured, wherein during the session, a remote computing resource is remotely administered, over a network, from a client, wherein a user associated with the client was previously authorized to administer the remote computing resource, and wherein connection between the remote computing resource and the client is supported via a particular protocol;

in response to receiving the indication, establish a session record associated with the remote administration session in a data store;

intercept an RDP session packet associated with the remote administration session and transmitted during the remote administration session, wherein the packet is intercepted from one of the client and the remote computing resource being remotely administered from the client;

an Internet Protocol (IP) address of the user,

a length of the session,

a start time of the session, and

a stop time of the session;

writing a file footer that is associated with the established session record;

in the event the packet is intercepted from the client and the remote computing resource is the intended destination of the intercepted packet, forwarding, from the gatekeeper device, the intercepted packet to the remote computing resource;

in the event that the packet is intercepted from the remote computing resource and the client is the intended destination of the intercepted packet, forwarding, from the gatekeeper device, the intercepted packet to the client;

performing post-processing, wherein the post-processing includes:
