Three Quick Tips For Server Security
Over the years, in all our dealings with web hosting and server maintenance, we’ve learned to be careful when it comes to our hardware security. Hacks are more common than you’d like to think, but thankfully most of them come through a recognizable list of patterns. Through our experiences locking down our software, we’ve identified three quick ways in which you can improve your security. They aren’t full-proof, but then again, that’s our first tip about server security: Security measures change almost constantly, meaning you’ll need to stay on your toes to stay updated. Constant research and reading keeps you informed, and your servers safe.
That was a freebie—now to the real tips!
1. Firewalls Aren’t Bullet-Proof: Firewalls are designed to protect your internal network from outside influences. They’ll guard you against any unwanted attacks that flow down the pipes, but is that all you need to keep hackers away? Well, no actually. You see, Firewalls no more protect you from weaknesses in your operating system or software than an umbrella protects you from stray dogs. It keeps you covered in one direction, but if a Firewall is the only thing between you and the hordes out there on the Internet, you may want to keep reading.
2. There’s Gold In Your /tmp Directory: If we’ve learned anything over the years, it’s that intruders love the /tmp directory. This folder has the potential to wreak havoc on your server, as well as others. When intruders want to exploit your software weaknesses, they often leave scripts here, where they can unfold and blossom into right pains in the derriere. So what’s a boy to do with their /tmp folder? Lock it down, that’s what! Be sure this directory is tighter than Fort Knox at night on a holiday, and you’ll be golden. It’s not a guaranteed fix, but it will certainly save you a lot of headaches in the future if you do it right.
3. You May Be Unsecured And Clueless: Often times we think of a hack as being an end-all catastrophe that will be noticed almost immediately. The sad truth is that your system could have been compromised a long time ago, and totally without you noticing. Almost every efficient hack is subtle and hard to see, especially if its particularly insidious. The best way to fight this is to keep on your toes and check your hardware regularly. Do as many checkups as you can find (or stand) as you never know when something may have gone wrong under the covers.
