Abstract

A security application manages security and reliability of networked applications executing collection of interacting computing elements within a distributed computing architecture. The security application monitors various classes of resources utilized by the collection of nodes within the distributed computing architecture and determine whether utilization of a class of resources is approaching a pre-determined maximum limit. The security application performs a vulnerability scan of a networked application to determine whether the networked application is prone to a risk of intentional or inadvertent breach by an external application. The security application scans a distributed computing architecture for the existence of access control lists (ACLs), and stores ACL configurations and configuration changes in a database. The security application scans a distributed computing architecture for the existence of security certificates, places newly discovered security certificates in a database, and deletes outdated security certificates. Advantageously, security and reliability are improved in a distributed computing architecture.

Claims

1. A computer-implemented method, comprising:

discovering a resource stored within at least one memory element included in a distributed computing architecture;

determining a classification for the resource based on one or more classification criteria;

determining whether the classification corresponds to a record within a database; and

if the classification corresponds to a record within the database, then;

incrementing a counter associated with the record;

or

if the classification does not correspond to a record within the database, then;

initializing another record within the database that corresponds to the classification, and

initializing another counter associated with the another record.

2. The method of claim 1, wherein the resource comprises an instance of a software application executing within the distributed computing architecture.

3. The method of claim 1, further comprising generating a notification when the classification does not correspond to a record within the database.

4. The method of claim 1, further comprising retrieving a first threshold value associated with the record, and generating a notification when the counter exceeds the first threshold value.

5. The method of claim 4, wherein generating the notification comprises publishing a message to a publication/subscription system indicating that the counter exceeds the first threshold value.

6. The method of claim 1, further comprising retrieving a second threshold value associated with the record, and generating a second notification when the counter exceeds the second threshold value.

7. The method of claim 6, wherein at least one of the first threshold value and the second threshold value comprises a percentage of a maximum limit.

8. A non-transitory computer-readable storage medium including instructions that, when executed by a processor, cause the processor to perform the steps of:

scanning a networked application stored within at least one memory element included in a distributed computing architecture to detect a first security vulnerability;

comparing the first security vulnerability against a database that includes a listing of previously-discovered security vulnerabilities; and

if the first security vulnerability is not listed within the database, then;

initializing a record within the database that corresponds to the first security vulnerability;

or

if the first security vulnerability is listed within the database, then;

updating a record within the database that corresponds to the first security vulnerability to indicate that the first security vulnerability was detected.

9. The non-transitory computer-readable storage medium of claim 8, wherein the database includes an issue tracking system that is configured to track whether one or more security vulnerabilities have been resolved.

10. The non-transitory computer-readable storage medium of claim 8, wherein the operation further comprises generating a notification when the record corresponding to the first security vulnerability is initialized.

11. The non-transitory computer-readable storage medium of claim 8, wherein updating the record within the database further comprises:

determining that the first security vulnerability is marked as being resolved; and

generating a notification that the first security vulnerability was detected.

12. The non-transitory computer-readable storage medium of claim 8, wherein scanning the networked application further comprises generating a notification that the distributed computing architecture is being scanned for security vulnerabilities.

13. The non-transitory computer-readable storage medium of claim 12, wherein generating the notification comprises publishing a message to a publication/subscription system indicating that the distributed computing architecture is being scanned for security vulnerabilities.

14. The non-transitory computer-readable storage medium of claim 12, wherein generating a notification comprises generating an automatic email indicating that the distributed computing architecture is being scanned for security vulnerabilities.

15. An administration server, comprising:

a memory storing a security application; and

a processor coupled to the memory, wherein, when executed by the processor, the security application configures the processor to;

discover an access control list (ACL) stored within at least one memory element included in a distributed computing architecture;

determine whether the ACL corresponds to a first record within a database; and

if the ACL corresponds to a record within the database, then

determine that a configuration of the ACL differs from a configuration of the record; and

initialize another record within the database that corresponds to the record and has the configuration of the ACL;

or

if the ACL does not correspond to a first record within the database, then

initialize another record within the database that corresponds to the ACL and has the configuration of the ACL.

16. The system of claim 15, wherein the ACL comprises a security group that includes one or more source objects, one or more ports, and one or more destination objects.

17. The system of claim 16, wherein the one or more source objects are identifiable via an internet protocol (IP) address.

18. The system of claim 16, wherein the one or more source objects are identifiable based on the one or more source objects included in the security group.

19. The system of claim 16, wherein the processor is further configured to compute an exposure metric for the security group based on at least one of the number of source objects included in the security group, the number of ports included in the security group, and the number of destination objects included in the security group.

20. The system of claim 15, wherein the processor is further configured to analyze the ACL to determine whether the ACL is associated with a permission setting that permits the security group to access all routable addresses on the Internet.

21. The system of claim 15, wherein the processor is further configured to compute the number of instances of a software application that execute within the ACL.
