Image vulnerability repair in a networked computing environment
Embodiments of the present invention provide an approach to repair vulnerabilities (e.g., security vulnerabilities) in images (e.g., application images) in a networked computing environment (e.g., a cloud computing environment). Specifically, an image is checked for vulnerabilities using a database of known images and/or vulnerabilities. If a vulnerability is found, a flexible/elastic firewall is established around the image so as to isolate the vulnerability. Once the firewall has been put in place, the vulnerability can be repaired by a variety of means such as upgrading the image, quarantining the image, discarding the image, and/or generating a new image. Once the image has been repaired, the firewall can be removed.
1. A method for repairing image vulnerability in a networked computing environment, comprising:
identifying an image in the networked computing environment having a vulnerability, the image being identified based on a database of known vulnerabilities;
establishing a firewall around the image to isolate the vulnerability;
repairing the image to remove the vulnerability, the repairing comprising discarding the image and generating a new image; and
removing the firewall.
2. The method of claim 1 , the image being an application image.
3. The method of claim 1 , the vulnerability being a security vulnerability.
4. The method of claim 1 , the repairing comprising upgrading the image.
5. The method of claim 1 , the repairing comprising quarantining the image.
6. The method of claim 1 , further comprising updating the database based on the repairing.
7. A system for repairing image vulnerability in a networked computing environment, comprising:
a bus;
a processor coupled to the bus; and
a memory medium coupled to the bus, the memory medium comprising instructions to:
identify an image in the networked computing environment having a vulnerability, the image being identified based on a database of known vulnerabilities;
establish a firewall around the image to isolate the vulnerability;
repair the image to remove the vulnerability, the repairing comprising discarding the image and generating a new image; and
remove the firewall.
8. The system of claim 7 , the image being an application image.
9. The system of claim 7 , the vulnerability being a security vulnerability.
10. The system of claim 7 , the memory medium further comprising instructions to upgrade the image.
11. The system of claim 7 , the memory medium further comprising instructions to quarantine the image.
12. The system of claim 7 , the memory medium further comprising instructions to update the database based on the repair.
13. A computer program product for repairing image vulnerability in a networked computing environment, the computer program product comprising a computer readable storage device, and program instructions stored on the computer readable storage media, to:
identify an image in the networked computing environment having a vulnerability, the image being identified based on a database of known vulnerabilities;
establish a firewall around the image to isolate the vulnerability;
repair the image to remove the vulnerability, the repairing comprising discarding the image and generating a new image; and
remove the firewall.
14. The computer program product of claim 13 , the image being an application image.
15. The computer program product of claim 13 , the vulnerability being a security vulnerability.
16. The computer program product of claim 13 , further comprising program instructions stored on the computer readable storage media to upgrade the image.
17. The computer program product of claim 13 , further comprising program instructions stored on the computer readable storage media to quarantine the image.
18. The computer program product of claim 13 , further comprising program instructions stored on the computer readable storage device to update the database based on the repair.
19. A method for deploying a system for repairing image vulnerability in a networked computing environment, comprising:
deploying a computer infrastructure being operable to:
identify an image in the networked computing environment having a vulnerability, the image being identified based on a database of known vulnerabilities;
establish a firewall around the image to isolate the vulnerability;
repair the image to remove the vulnerability, the repairing comprising discarding the image and generating a new image; and
remove the firewall.
