Conclusion

Much like a compromised system, it doesn't really matter if the cat is dead or alive. At some point, the poison gas will be released, you will end up with a dead cat, and eventually it will start stinking the place up.

The trick is to find effective ways to deal with failures so that you can be back up and running quickly and securely!

The Author

Kurt Seifried is an Information Security Consultant specializing in Linux and networks since 1996. He is married and has four cats but no fish (because the cats are more hungry than afraid of water). He often wonders how it is that technology works on a large scale but often fails on a small scale.
