Hey, I just got an email saying I won a million dollars! *Click* Wait, what just happened to my computer?

This is usually how it starts. Some shady person sends out spam telling people they have one a million dollars or a free laptop or mp3 player with a link a form they need to fill out to claim their prize. Only you don’t win an mp3 player or laptop. You win an infected computer that is now a drone in a much larger botnet. This botnet is either for direct malicious purposes (Denial-of-Service attacks) or indirect malicious purposes (spam, phishing, etc). How do you stop this from happening to you and you becoming “that guy”? Don’t click links in email unless you’re 100% sure who it’s from and what it’s for. That’s the basic rule to remember. Secondly, make sure you have an anti-virus program that’s capable of scanning email and keeping your system protected from malicious browser exploits. Thirdly, (and this should go without being said, but I’m saying it anyways) make sure your computer (and all software) is up-to-date. Sure, there’s the occasional bug and 0-day exploit on up-to-date systems, but there’s a whole slew of exploits and things that can be done to an un-patched system. Keep your systems up-to-date and you reduce the “known” exploits from literally thousands to maybe a few.

Think about this, 80% of the world’s email is considered spam. Of that 80%, the vast majority (more than 75%) is sent using infected computers (drones). If everyone would re-think blindly clicking links in emails and on webpages (social networking sites have a history of people trying to fool users into clicking bad links) then the spammers wouldn’t have drones available to them to send spam. Interesting thought, isn’t it? Let’s stop spam by being smart internet users and denying the “bad guys” the resources they need to send out the spam.

Always Use Protection

When it comes to managing a server remember you can never be to careful. In this day and age we face a lot of things that can damage and even take a server to its knees here’s a few things for everyone to consider.

Anti-virus:

This is a must on systems open to the net now days. There are always nasty little things floating around looking to take your server apart from the OS out. For windows servers there are a multitude of choices and I’ll just mention a few that can help protect your goods. You can use several programs such as avast (which offers a free edition), ClamWin (open source), Kaspersky , and Panda just to name a few. I would suggest before installing any of these you check links such as http://en.wikipedia.org/wiki/List_of_antivirus_software to name one that provides a list of several choices and their compatibility. You may also want to read reviews that compare the available options and give you an idea of what to expect from them. This will allow you to make an informed choice on which one works best for you. Now with linux there are also several options for this including the well known clamav which from personal experience works really well and can be installed on a variety of linux disro’s(aka distributions). It’s very simple to use and may prevent you from headache later on down the road.

Firewalls:

Firewalls are a double edged sword but are most defiantly needed. When it comes to firewalls you can protect yourself from quite a bit of headache however if setup to strict you can block positive traffic and even yourself from reaching your server but in the long run a defiant way to help protect your server from unwanted visitors. A lot of firewalls also have modules and add-ons that further assist in protecting you and securing your server. If in doubt it’s always a good idea to have a security company do an audit and even a security hardening session with your server to make sure you are protected the best way possible.

Passwords:

This is probably one of the most important this you can do to secure your server. Use strong passwords (no using password or jello is not a secure password even if it is in all caps) and if you are worried about not being able to come up with a secure one there are several password generators on the web that can come up with secure ones to assist. Passwords should contain caps letters, numbers, symbols, and should be at minimum 8 – 10 characters (the more the better). It’s the easy to remember and easy read passwords that get you into trouble.

Armed with this information and so much more on security that can be located on the web using the great and all powerful Google should be a good start to making sure you don’t have to worry about data loss and system hacks. Also remember no matter how secure you think you are make regular backups of all your important data as if you server could crash at any time.
