Detecting unauthorized risky or inefficient usage of privileged credentials through analysis of task completion timing
View Patent ↗A privileged account management system can maintain a database that defines a normal amount of time that it takes to perform a task associated with a reason code. When an administrator requests admin credentials for accessing a server, the administrator can provide a reason code which defines a task that the administrator intends to accomplish. A PAM system can maintain a database that defines, for each reason code, a normal amount of time that is required to accomplish the task associated with the reason code. The PAM system can then monitor an elapsed time over which the admin credentials are checked out to an administrator to determine whether the elapsed time exceeds the corresponding normal amount of time. If the elapsed time exceeds the normal amount, the PAM system can take appropriate action to mitigate any potential harm to the server.
1. A method, implemented by a privileged account management system that comprises at least one processor and memory, for detecting unauthorized, risky, or inefficient usage of admin credentials, the method comprising:
maintaining, by the privileged account management system, a database that defines, for each of a plurality of reason codes, a normal amount of time for performing a task associated with the reason code;
receiving, from a first administrator using a client device, a request for admin credentials to be used to access a first server, the request including a first reason code that identifies a first task that the first administrator intends to perform on the first server;
in response to the request, checking out the admin credentials to the first administrator to enable the first administrator to access the first server;
accessing the database to identify a first normal amount of time that is defined for the first reason code;
tracking an elapsed time over which the admin credentials are checked out to the first administrator;
comparing the elapsed time to the first normal amount of time; and
when the elapsed time exceeds the first normal amount of time by a defined threshold, taking an action to mitigate harm to the server.
2. The method of claim 1 , wherein the database stores a plurality of normal amounts of time for the first reason code, and wherein the first normal amount of time defines an amount of time that the first administrator normally takes to perform the first task.
3. The method of claim 1 , wherein the database stores a plurality of normal amounts of time for the first reason code, and wherein the first normal amount of time defines an amount of time that is normally required to perform the first task on the first server.
4. The method of claim 1 , wherein the database stores a plurality of normal amounts of time for the first reason code, and wherein the first normal amount of time defines an amount of time that the first administrator normally takes to perform the first task on the first server.
5. The method of claim 4 , wherein the plurality of normal amounts of time for the first reason code includes a second normal amount of time that defines an amount of time that the first administrator normally takes to perform the first task on a second server.
6. The method of claim 4 , wherein the plurality of normal amounts of time for the first reason code includes a second normal amount of time that defines an amount of time that a second administrator normally takes to perform the first task on the first server.
7. The method of claim 1 , wherein the action comprises notifying a security officer that the elapsed time has exceeded the first normal amount of time.
8. The method of claim 1 , wherein the action comprises flagging, monitoring, recording, or killing a remote session between the client device and the first server.
9. The method of claim 1 , wherein the action comprises storing a notice in association with the request, the notice identifying that the elapsed time exceeded the first normal amount of time.
10. The method of claim 1 , wherein the first normal amount is generated based on a plurality of previously monitored elapsed times that were associated with the first reason code.
11. The method of claim 1 , wherein checking out the admin credentials comprises one of:
sending the admin credentials to the client device; or
creating a remote session with the client device to allow the client device to access the first server.
12. The method of claim 1 , wherein the action is taken while the admin credentials remain checked out to the first administrator.
13. A method, implemented by a privileged account management system that comprises at least one processor and memory, for creating a database that defines, for each of a plurality of reason codes, a normal amount of time for performing a task associated with a reason code, the method comprising:
for each of the plurality of reason codes:
receiving, at the privileged account management system, a plurality of requests, from one or more administrators using one or more client devices, for admin credentials that specify the reason code;
for each of the plurality of requests, identifying an elapsed time over which the admin credentials were checked out while a task associated with the reason code was performed; and
generating a normal amount for the reason code based on the plurality of identified elapsed times such that the normal amount defines an amount of time that is normally required to perform the task associated with the reason code.
14. The method of claim 13 , further comprising:
for at least one of the plurality of reason codes:
for each of the plurality of requests, identifying criteria of the request, the criteria comprising one or both of an administrator that made the request and a server specified in the request; and
generating a plurality of normal amounts for the reason code, each normal amount being specific to a different combination of the identified criteria.
15. The method of claim 14 , wherein for the at least one of the plurality of reason codes, the plurality of normal amounts comprise a first normal amount that defines an amount of time that a first administrator normally takes to perform the associated task on a first server and a second normal amount that defines an amount of time that that first administrator normally takes to perform the associated task on a second server.
16. The method of claim 14 , wherein for the at least one of the plurality of reason codes, the plurality of normal amounts comprise a first normal amount that defines an amount of time that a first administrator normally takes to perform the associated task on a first server and a second normal amount that defines an amount of time that a second administrator normally takes to perform the associated task on the first server.
17. The method of claim 13 , wherein generating a normal amount comprises updating a previously generated normal amount.
18. A privileged account management system comprising:
one or more processors; and
one or more non-transitory computer storage media storing computer executable instructions which when executed by the one or more processors implement a method for detecting unauthorized, risky, or inefficient usage of admin credentials, the method comprising:
maintaining a database that defines, for each of a plurality of reason codes, a plurality of normal amounts of time for performing a task associated with the reason code, each of the plurality of normal amounts of time being associated with a different combination of criteria, each combination of criteria comprising one or more of an administrator that performs the task and a server on which the task is performed;
receiving, from a first administrator using a client device, a request for admin credentials to be used to access a first server, the request including a first reason code that identifies a first task that the first administrator intends to perform on the first server;
in response to the request, checking out the admin credentials to the first administrator to enable the first administrator to access the first server;
accessing the database to identify a first normal amount of time that is defined for the first reason code, the first normal amount also being associated with a combination of criteria including one or both of the first administrator and the first server;
tracking an elapsed time over which the admin credentials are checked out to the first administrator;
comparing the elapsed time to the first normal amount of time; and
when the elapsed time exceeds the first normal amount of time by a defined threshold, taking an action to mitigate harm to the server.
19. The privileged account management system of claim 18 , wherein the first normal amount is associated with the first administrator and the first server.
20. The privileged account management system of claim 18 , further comprising:
receiving a second request that includes the first reason code; and
accessing the database to identify a second normal amount of time that is defined for the first reason code, the second normal amount being associated with a different combination of criteria than the combination of criteria associated with the first normal amount.
