Always Update your software :-
Hackers and malicious code can exploit security holes in a firewall allowing data to be sent and majority it effect the older software version’s .If you are running old versions of software or applications chances are it’s insecure, make sure you upgrade to the latest release or the latest updates of it. Most updates to software are security or functionality related, which means if you aren’t running the latest version you are likely to have missed a few security fixes.
Most Important – Prevent Spam:-
Spam is unsolicited e-mail which is sent in massive quantities to unsuspecting Internet email users. Usually, the free hosting are the ones which get affected by this spamming. Spam messages usually carry harmful virus, spy-wares, and other kind of harmful applications with them which can harm your computer or infect your website’s important files. It also affects the bandwidth and the disk space of your web hosting server. So, there should be an anti-spam program or tool installed in your website to prevent spam and, in turn, make your website very secured.
3rd Party Scripts or 3rd Party Code :-
On Internet there are plenty of 3rd Party Scripts, 3rd Party Code,plugins,widgets or any other code which also including free templates and themes you install are written by other people under unknown circumstances. Some may be very help full but some may be full of holes which may destroy your internal software script and can brig bugs into it. Make sure to research first on any of the code you want to use with in your website that you didn’t write yourself. Even a few Google or Yahoo searches should help you find out how secure the code you are using is.
Your Own Bug’s or Error :-
One of the biggest causes of personal theft or internal bug’s and an easy way for someone to get details to your sites. Your own computer is likely to be a weak link in the chain. Whether it be from poisoned power point files or someone phishing your account details, the vulnerabilities are limitless. No matter how secure your site is, if the machine you access it from (including logging in and editing etc.) is not secure you stand a good risk of being compromised and it may affect more than just your site.
DDOS Prevention :-
Denial of Service (DOS) and Distributed Denial of Service (DDOS) attacks are some of the oldest known threats which directly targer the operating systems of the computer. Its a still a very well known effective solutions. They slow down the online web servers. This slowing down affects all the websites present on that particular web server. The anti-DDOS software is now available and is included in the firewall and router. All these important security features are now being implemented by most of the web host in their web servers effectively.
Secure Passwords :-
A secure password goes a long way to slowing down a potential infiltrator (real ‘hackers’ do not tend to be people that destroy sites, but ethically search for security holes in technology). Put simply passwords should always be a combination of letters and numbers, uppercase and lowercase. The longer the password, the better (though conversely the longer it is the harder it is to remember).No dictionary words, no family names and no easily guess-able information either.
Outsource a Little Prevention :-
Using high quality software, a good coder (one who is security aware), hiring a professional security agency or using an automated method like the Firewall script or Hacker safe will help to reduce your risk. What you outsource depends on your needs (and resources of course).
Always keep Backup some at some different place :-
While this tip won’t protect you from being hacked, it will be very beneficial to you should it happen.
