Systems and methods for implementing security
Systems and method are provided in accordance with one or more processes that run within an operating system, in which a first process of the one or more processes is an agent that encodes instructions for obtaining an authentication token uniquely associated with the agent. The agent collects security information about a first computer system running the one or more processes according to one or more commands received from a remote security system. The collected information is transmitted to the remote security system on an encrypted communication channel between the agent and the remote security system using the authentication token. Executable instructions are received through the encrypted communication channel at the first computer from the remote server according to a security policy assigned to the agent. The received executable instructions are executed at the first computer system, thereby implementing the assigned security policy.
1. A first computer system comprising:
one or more processing units;
memory, coupled to at least one of the one or more processing units, wherein the memory stores an operating system, and wherein the operating system is executed by the one or more processing units; and
one or more programs that run within the operating system, wherein a first program of the one or more programs is an agent that is executed by at least one of the one or more processing units, and wherein the agent includes instructions for:
initiating a communication with a remote security system in order to obtain an authentication token that is uniquely associated with the agent;
receiving a plurality of executable instructions from the remote security server according to a security policy assigned to the agent, wherein the instructions are received through an encrypted communication channel between the agent and the remote security system, and wherein the encrypted communication channel uses the authentication token; and
executing, at the first computer system, the plurality of received executable instructions, thereby implementing a security policy of the assigned security policy, wherein the agent initiates all communication with the remote computer system, the remote computer system cannot initiate communication with the agent, and the remote computer system identifies the executable instructions for the agent by placing them in a command queue associated with the agent.
2. The first computer system of claim 1 wherein the agent further includes instructions for:
collecting security information about the first computer system according to one or more commands of the plurality of executable instructions of the security policy; and
transmitting the collected security information to the remote security system on the encrypted communication channel.
3. The first computer system of claim 2 , wherein the collected security information identifies name-value pairs associated with the one or more processes or name-value pairs for privileges associated with the first computer system.
4. The first computer system of claim 2 , wherein the collected security information includes a plurality of data points related to forensic analysis for detection of compromise of the first computer system.
5. The first computer system of claim 2 , wherein the collected security information identifies what ports the one or more processes are listening on.
6. The first computer system of claim 2 , wherein transmitting the collected information uses private information shared but not exchanged with the remote security system to digitally sign and encrypt the collected information prior to transmitting.
7. The first computer system of claim 2 , wherein the collected information identifies configurations of the one or more programs.
8. The first computer system of claim 2 , wherein the collected security information includes data related to the integrity of programs and data structures resident on the first computer system.
9. The computer system of claim 2 , wherein
the receiving the plurality of executable instructions comprises obtaining the plurality of executable instructions from the command queue uniquely associated with the agent.
10. The first computer system of claim 1 , wherein the command queue is encrypted.
11. The first computer system of claim 10 , wherein the command queue is encrypted using the authentication token.
12. The first computer system of claim 1 , wherein the plurality of executable instructions include updates to a firewall policy for the first computer system.
13. The first computer system of claim 1 , wherein the plurality of executable instructions include updates to user privileges for the first computer system.
14. The first computer system of claim 1 , wherein the plurality of executable instructions include delivery of data values related to cryptographic operations to be conducted on the first computer system to access persistent data on the first computer system.
15. The first computer system of claim 1 , wherein the plurality of executable instructions include instructions for retrieval and use of data values related to cryptographic operations to be conducted on the first computer system in order to access persistent data on the first computer system.
16. The first computer system of claim 1 , wherein the plurality of executable instructions perform one of (i) a check a status of a setting associated with a file stored in the memory, (ii) a check a setting of a directory stored in the memory, (iii) a check a password associated with a user of the first computer system, or (iv) a check a password associated with a group of users of the first computer system.
17. The first computer system of claim 1 , wherein the plurality of executable instructions include updates to implement a failsafe action on the first computer system in the event of security compromise of the first computer system.
18. The first computer system of claim 17 , wherein the failsafe action comprises sending an administrator an alert, shutting down of a virtual machine on the first computer system, shutting down the agent, sending an alert to a user by e-mail, initiating forensic data collection on the first computer system, updating a firewall rule for the first computer system, or updating a configuration parameter on the first computer system.
19. The first computer system of claim 1 , wherein there is private information shared but not exchanged with the remote security system and wherein the authentication token and the shared private information enable the encrypted communication channel.
20. The first computer system of claim 1 , wherein the operating system and the one or more programs run within a first virtual machine within the memory.
21. The first computer system of claim 20 , wherein the first virtual machine is one of a plurality of virtual machines running on the first computer system.
22. The first computer system of claim 21 , wherein the assigned security policy encompasses the plurality of virtual machines running on the first computer system.
23. The first computer system of claim 1 , wherein the assigned security policy encompasses a plurality of computer systems, including the first computer system.
24. The first computer system of claim 1 , wherein
the one or more programs run within a virtual machine,
the plurality of executable instructions comprises a first command set and a second command set,
the first command set includes a first command to check a state of the operating system, and
the second command set includes a second command to check a state of a program in the one or more programs or a state of a data structure stored in the memory.
25. The first computer system of claim 1 , wherein the plurality of executable instructions include an action command, and wherein, subsequent to execution of the action command, the execution status of the action command is transmitted to the remote security system.
26. The first computer system of claim 1 , wherein
the operating system is running in a virtual machine,
the plurality of executable instructions includes an action command, and
the action command specifies:
(i) deleting, moving, or renaming of a file, combination of files, or a directory in the memory,
(ii) altering a privilege of a user of the virtual machine,
