Any additional documentation can be linked to or attached. I am sending it to some pals ans also sharing in delicious. Create a “Bring Your Own Device” policy now, even if that policy is just to prohibit users from bringing their personal laptops, tablets, etc. Never let this be one of the things you forget to get back to. It is really a concise representation of all the points that need to be secured. If you can’t install and use an external AAA … In some cases it’s even more so, since your servers benefit from the physical security of your datacenter, while workstations are frequently laptops sitting on table tops in coffee shops while your users grab another latte. syslog, Log all successful privileged EXEC level device management access using centralized AAA or an alternative, e.g. Include all your network gear in your regular vulnerability scans to catch any holes that crop up over time. Create a server deployment checklist, and make sure all of the following are on the list, and that each server you deploy complies 100% before it goes into production. Everyone has their own method; the most common approach is probably keeping a cheat sheet (which is just a concise list of the items you think apply to you). If you answered yes, you’re doing it wrong. See Security Hardening Checklist (Link opens in a new window) Installing security updates. Don’t forget those service tags! A lot of helpful info here.
