So, are you using Cisco? Here’s what you should do:
- Verify if your Cisco devices fall under the linked CVEs below
- Patch those devices with the latest updates/firmware
- Patch every other Cisco device you use, even if not listed in CVE
- Monitor systems and network for potential footholds
Good luck, and have fun!
This is pretty generic advice, but if you are mature enough in your IT infrastructure to already have an actual security response plan that maps out the steps you should take - then use that.
