Managing use of security keys
View Patent ↗A method is used in managing use of security keys. Based on a request for use of a key that serves as part of a data security system, a set of criteria to apply to the request is determined. The set of criteria pertain to security management of the key that is subject of the request. The set of criteria is applied to the request; and a result is determined based on the application of the set of criteria.
1. A computer-implemented method, comprising executing, on at, least one processor, the steps of:
receiving a current request for use of a key that serves as part of a data security system, wherein the current request comprises a current location and a current time and a device identifier identifying a device associated with the current request;
upon receiving the current request, determining at least one policy pertaining to security management of the key to apply to the current request, wherein the at least one policy requires a risk analysis of the current request, further wherein the at least one policy indicates a limit that limits a number of times the key or keys that are part of the data security system can be accessed by the device or a group of devices;
applying the at least one policy to the current request, wherein the said application of the at least one policy comprises analyzing the current, location and the current time and a history in connection with previous requests;
determining a first level of riskiness in connection with the current request based on the application of the at least one policy, wherein the first level of riskiness indicates a high risk in connection with the current request; and
based on the first level of riskiness, determining to refuse permission to use the key, wherein the said determination includes creating a new limit to replace the limit in order to reduce the number of times the key or keys that are part of the data security system can be accessed by the device or the group of devices.
2. The method of claim 1 , wherein a key manager releases the key according to the policy that includes a rule that indicates that additional authentication factors are necessary.
3. The method of claim 1 , wherein the policy is applied in a security token.
4. The method of claim 1 , wherein the policy is applied in a mobile device storing the key with hardware implementing an access policy based on a third party cloud service and a trustworthy time base.
5. The method of claim 1 , wherein a device is directed to decrypt sensitive data encrypted under the key, and the device requests the key from a key manager for decryption.
6. The method of claim 1 , wherein according to the policy a device cannot get access to more than a maximum number of keys within a short time frame.
7. A system, comprising:
a processor and memory;
the system configured to:
receive a current request for use of a key that serves as part of a data security system, wherein the current request comprises a current location and a current time and a device identifier identifying a device associated with the current request;
upon receiving the current request, determine at least one policy pertaining to security management of the key to apply to the current request, wherein the at least one policy requires a risk analysis of the current request, further wherein the at least one policy indicates a limit that limits a number of times the key or keys that are part of the data security system can be accessed by the device or a group of devices;
apply the at least one policy to the current request, wherein the said application of the at least one policy comprises analyzing the current location and the current time and a history in connection with previous requests;
determine a first level of riskiness in connection with the current request based on the application of the at least one policy, wherein the first level of riskiness indicates a high risk in connection with the current request; and
based on the first level of riskiness, determine to refuse permission to use the key, wherein the said determination includes creating a new limit to replace the limit in order to reduce the number of times the key or keys that are part of the data security system can be accessed by the device or the group of devices.
8. The system of claim 7 , wherein a key manager releases the key according to the policy that includes a rule that indicates that additional authentication factors are necessary.
9. The system of claim 7 , wherein the policy is applied in a security token.
10. The system of claim 7 , wherein the policy is applied in a mobile device storing the key with hardware implementing an access policy based on a third party cloud service and a trustworthy time base.
11. The system of claim 7 , wherein a device is directed to decrypt sensitive data encrypted under the key, and the device requests the key from a key manager for decryption.
12. The system of claim 7 , wherein according to the policy a device cannot get access to more than a maximum number of keys within a short time frame.
