Systems and methods for evasive resiliency countermeasures
Evasive resiliency countermeasures techniques that include: implementing a cyber asset in a network element of a plurality of network elements, monitoring operations of the network; detecting an adverse event within the network; in response to detecting the adverse event, removing an availability of the cyber asset at the network element; determining when the adverse event has ended; and, in response to determining that the adverse event has ended, restoring the availability of the cyber asset at the network element.
1. A system for performing evasive resiliency countermeasures:
a network including a plurality of network elements;
the plurality of network elements including at least a first network element and a second network element;
the first network element is configured to: i) monitor operations of the network, ii) detect an adverse event within the network, wherein the adverse event includes at least one of a network intrusion, malicious insider, denial-of-service attack, presence of at least one of a virus and a trojan horse, actions of at least one of the virus and the trojan horse, presence of malware, actions of the malware, and unauthorized activities, iii) in response to detecting the adverse event, issue a first notification, by the first network element, either directly or indirectly to at least one element on the network in communication with the first network element, indicating a detection of the adverse event, iv) determining when the adverse event has ended, and v) in response to determining that the adverse event has ended, issue a second notification, by the first network element, indicating that the adverse event has ended; and
the second network element is configured to: i) implement a cyber asset at the second network element, wherein the cyber asset includes at least one of a data file, database, application, service, data interface, and an operating system component, ii) receive the first notification, and iii) in response to receiving the first notification, migrating one or more portions of the cyber asset that is affected by the adverse event, including at least a portion of executable code of the cyber asset, from the second network element to one or more other network elements different from at least the second network element,
wherein the second network element breaks up portions of the migrated cyber asset into randomized file chunks, encrypts the randomized file chunks, and migrates the encrypted randomized file chunks to said one or more other network elements.
2. The system of claim 1 , wherein the one or more portions of the cyber asset include one or more chunks of data in addition to said at least a portion of executable code of the cyber asset.
3. The system of claim 1 , wherein said one or more other network elements are remotely located from the second network element.
4. The system of claim 3 , wherein locating remotely includes locating the one or more other elements outside of a firewall associated with the network.
5. The system of claim 1 , wherein removing the availability of the cyber asset includes deactivating or shutting down a partial functionality of the second network element to limit access to the cyber asset.
6. The system of claim 1 , wherein removing the availability of the cyber asset includes archiving migrated portions of the cyber asset utilizing a removable media or a remote storage system or service.
7. The system of claim 1 , wherein the second network element includes a server operating within the network.
8. The system of claim 1 , wherein the first network element includes a security monitoring server.
9. A method for performing evasive resiliency countermeasures in a network comprising:
implementing a cyber asset m a first network element of a plurality of network elements, wherein the cyber asset includes at least one of a data file, database, application, service, data interface, and an operating system component, and wherein a network element includes at least one of a computer, server, database, removable storage device, remote storage system or service, router, firewall, internal computing device, removable computing component, and a mobile computing device;
monitoring, by the first network element, operations of the network;
detecting, using the first network element, an adverse event within the network, wherein the adverse event includes at least one of a network intrusion, malicious insider, denial-of-service attack, presence of at least one of a virus and trojan horse, actions of at least one of the virus or the trojan horse, presence of malware, actions of the malware, and unauthorized activities; and
in response to detecting the adverse event, migrating one or more portions of the cyber asset that is affected by the adverse event, including at least a portion of executable code of the cyber asset, from the second network element to one or more other network elements different from at least the second network element by breaking up portions of the cyber asset into randomized file chunks, encrypting the randomized file chunks, and migrating the encrypted randomized file chunks to said one or more other network elements.
10. The method of claim 9 , wherein the one or more portions of the cyber asset include one or more chunks of data in addition to said at least a portion of executable code of the cyber asset.
11. The method of claim 9 , wherein said one or more other network elements are remotely located from the second network element.
12. The method of claim 11 , wherein locating remotely includes locating the one or more other network elements outside of a firewall of the network.
13. The method of claim 9 , wherein removing the availability of the cyber asset includes deactivating or shutting down a partial functionality of the second network element to limit access to the cyber asset.
14. The method of claim 9 , wherein removing the availability of the cyber asset includes archiving migrated portions of the cyber asset utilizing a removable media or a remote storage system or service.
15. The method of claim 9 , wherein the network element includes a server operating within the network.
16. A non-transient computer readable medium containing program instructions for causing a computer to perform evasive resiliency countermeasures in a network comprising the method of:
implementing a cyber asset in a first network element of a plurality of network elements, wherein the cyber asset includes at least one of a data file, database, application, service, data interface, and an operating system component, and wherein a network element includes at least one of a computer, server, database, removable storage device, storage system or service, router, firewall, internal computing device, a removable computing component, and a mobile computing device;
monitoring, by the first network element, operations of the network;
detecting, using the first network element, an adverse event within the network, wherein the adverse event includes at least one of a network intrusion, malicious insider, denial-of-service attack, presence of at least one of a virus and trojan horse, actions of at least one of the virus and the trojan horse, presence of malware, actions of the malware, and unauthorized activities;
in response to detecting the adverse event, migrating one or more portions of the cyber asset that is affected by the adverse event, including at least a portion of executable code of the cyber asset, from the second network element to one or more other network elements different from at least the second network element by breaking up portions of the cyber asset into randomized file chunks, encrypting the randomized file chunks, and migrating the encrypted randomized file chunks to said one or more other network elements.
