Network portion risk assessment
Systems, methods, and related technologies for determining a risk associated with a network portion are described. The determination of risk associated with a network portion may include accessing network traffic from a network and determining an entity type associated with at least one entity communicatively coupled to the network. A network portion associated with the at least one entity can be determined. A risk associated with the at least one entity can be determined. A risk associated with the network portion associated with the at least one entity can be determined based on the risk associated with the at least one entity. The risk associated with the network portion can then be stored.
1. A method comprising:
accessing network traffic from a network;
determining an entity type associated with at least one entity communicatively coupled to the network;
determining a network portion including the at least one entity;
determining a risk associated with the at least one entity based on an impact of a potential attack on the at least one entity and a probability of the potential attack occurring with respect to the at least one entity;
determining, by a processing device and after determining the risk associated with the at least one entity, a risk associated with the network portion including the at least one entity based on the risk associated with the at least one entity;
storing the risk associated with the network portion; and
performing an action to reduce an attack surface of the network portion for the potential attack based on the risk associated with the network portion.
2. The method of claim 1 , wherein the risk associated with the at least one entity is based on at least one of a Common Vulnerabilities and Exposures (CVE) associated with the at least one entity, patch version, software version, security posture, or credentials.
3. The method of claim 1 wherein the action comprises at least one of changing a VLAN associated with the at least one entity, quarantining the at least one entity, initiating an update, tracking traffic of the at least one entity, or sending a notification associated with the at least one entity.
4. The method of claim 1 , wherein determining the risk associated with the at least one entity is based on the entity type associated with the at least one entity.
5. The method of claim 1 , wherein the at least one entity comprises a plurality of entities and wherein the risk associated with the network portion including the plurality of entities is based on the risk for each of the plurality of entities.
6. The method of claim 1 , wherein the risk associated with the at least one entity is based on a sensitivity associated with the at least one entity.
7. The method of claim 1 , wherein the risk associated with the at least one entity is based on an objective associated with at least one of entity risk, entity sensitivity, or entity types in the network portion.
8. The method of claim 1 , wherein the risk associated with the network portion is based on a sensitivity associated with the at least one entity.
9. A system comprising:
a memory; and
a processing device, operatively coupled to the memory, to:
access network traffic from a network;
determine an entity type associated with at least one entity communicatively coupled to the network;
determine a network portion including the at least one entity;
determine a risk associated with the at least one entity based on an impact of a potential attack on the at least one entity and a probability of the potential attack occurring with respect to the at least one entity;
determine, after the determination of the risk associated with the at least one entity, a risk associated with the network portion including the at least one entity based on the risk associated with the at least one entity;
store the risk associated with the network portion; and
perform an action to reduce an attack surface of the network portion for the potential attack based on the risk associated with the network portion.
10. The system of claim 9 , wherein the risk associated with the at least one entity is based on at least one of a Common Vulnerabilities and Exposures (CVE) associated with the at least one entity, patch version, software version, security posture, or credentials.
11. The system of claim 9 , wherein the action comprises at least one of changing a VLAN associated with the at least one entity, quarantining the at least one entity, initiating an update, tracking traffic of the at least one entity, or sending a notification associated with the at least one entity.
12. The system of claim 9 , wherein determining the risk associated with the at least one entity is based on the entity type associated with the at least one entity.
13. The system of claim 9 , wherein the at least one entity comprises a plurality of entities and wherein the risk associated with the network portion including the plurality of entities is based on the risk for each of the plurality of entities.
14. The system of claim 9 , wherein the risk associated with the at least one entity is based on a sensitivity associated with the at least one entity.
15. The system of claim 9 , wherein the risk associated with the at least one entity is based on an objective associated with at least one of entity risk, entity sensitivity, or entity types in the network portion.
16. The system of claim 9 , wherein the risk associated with the network portion is based on a sensitivity associated with the at least one entity.
17. A non-transitory computer readable medium having instructions encoded thereon that, when executed by a processing device, cause the processing device to:
access network traffic from a network;
determine an entity type associated with at least one entity communicatively coupled to the network;
determine a network portion including the at least one entity;
determine a risk associated with the at least one entity based on an impact of a potential attack on the at least one entity and a probability of the potential attack occurring with respect to the at least one entity;
determine, by the processing device and after the determination of the risk associated with the at least one entity, a risk associated with the network portion including the at least one entity based on the risk associated with the at least one entity;
store the risk associated with the network portion; and
perform an action to reduce an attack surface of the network portion for the potential attack based on the risk associated with the network portion.
18. The non-transitory computer readable medium of claim 17 , wherein the action comprises at least one of changing a VLAN associated with the at least one entity, quarantining the at least one entity, initiating an update, tracking traffic of the at least one entity, or sending a notification associated with the at least one entity.
19. The non-transitory computer readable medium of claim 17 , wherein the risk associated with the at least one entity is based on at least one of a Common Vulnerabilities and Exposures (CVE) associated with the at least one entity, patch version, software version, security posture, or credentials.
20. The non-transitory computer readable medium of claim 17 , wherein the risk associated with the network portion is based on a sensitivity associated with the at least one entity and wherein the risk associated with the at least one entity is based on the sensitivity associated with the at least one entity.
