os_actor_process_integrity_level	INTEGER	the integrity level of the process (INTEGER)
os_actor_process_is_64bit	BOOLEAN	Indicates whether or not the process is compiled for 64 bit.
os_actor_process_is_native	BOOLEAN	Indicates whether or not this process is a "native process". On a 32 bit machine the value will be always true, on 64 bit machine it will be true if the process is 64 bit.

os_actor_process_signature_product	STRING	Signature product - The product family part of the signature.
os_actor_process_signature_status	INTEGER	Signature status of the process: Signed = 1 SignedInvalid = 2 Unsigned = 3 FailedToObtain = 4 WeakHash = 5, where the MD5 is used as the hash algorithm. Unsupported = 6, which means the signature was not calculated. InvalidCVE2020_0601 = 7, which means the executable is malicious and is trying to exploit the windows vulnerability CVE2020-0601. Deleted = 8, which means that the file was deleted by the time the agent tried to calculate the signature.

os_actor_session_id	INTEGER	session id of the actor process
os_actor_thread_thread_id	INTEGER	thread id of the thread in the process which made the action
os_actor_type	INTEGER	Enum describing actor type: Local = 1. The actor is a local process RemoteRpcNamedPipe = 2. The actor is remote RPC over a named-pipe/SMB connection RemoteRpcHttp = 3. The actor is remote RPC a remote HTTP connection RemoteRpcTcp = 4. The actor is remote RPC over a TCP connection RemoteFileSmb = 5. The actor is a remote file operation over SMB
