Major Threats to Business Website Security

Any organization would find it irresponsible and downright silly to not have anti-virus software installed on their office systems.  Most would also have solutions in place to compensate for data restoration should their be a hardware failure or disaster caused by some sort of natural disaster.  Surprisingly enough, far two many business owners are unaware that their websites are vulnerable to the same type of attacks as their local machines.  This is especially the case in shared and virtual environments where a multitude of sites are running on the same server.

In May 2007, more than 90,000 sites were compromised by hackers, a large scale exploit designed to illegally install malicious code on the computers of visitors who clicked on seemingly harmless search results.  A StopBadware study showed that an estimated 10% of those compromised sites were maintained by one hosting firm in particular, which accounted for 250,000 infectious websites.  This is just one of many examples that prove no website is ever as safe as we might think.

Common Threats to Business Websites

Hackers employ several methods and tricks to exploit websites.  Below we will focus on three that are most commonly used to attack business sites: SQL injection, cross site scripting and CRLF injection.

SQL Injection

SQL injection is by far one of the most popular website attacks employed today.  This technique primarily works by sending false or malicious requests to a back-end database to manipulate the information it contains.  By doing so, the attacker can view whatever information is stored in the database, change it, or erase it completely.  Most websites would not exist without the presence of databases but unfortunately, any site that features shopping carts, search fields, and any type of web form is susceptible to SQL injection.  The fields that require interaction from your visitors and customers could open up the door a hacker needs to thieve sensitive data and destroy your company.

Cross Site Scripting

Cross site scripting is another common attack that exploits holes in dynamic websites.  Dynamic pages can allow an attacker to insert malicious code and trick an end-user into running a harmful script on their computer.  If the user executes the code, the hacker could gain access to all of the sensitive information on their local machine.  Cross site scripting takes advantage of numerous programming technologies including Active X, Flash, Javascript and VBScript.

CLRF Injection

Unlike most exploits, CLRF injection does not take advantage of security vulnerabilities in the operating system or web software.  Instead, it exploits the manner in which the application was scripted.  For instance, an attacker can insert a statement into a web form along with code from CR (Carriage Return) and LF (Line Feed) characters.  The chance for exploit arises when the application mistakes this injection for a CLRF used in the initial development stage.  This attack is very dangerous as it has the power to disable an entire website.

This article is not aimed to make you a website security expert, but make you aware that security for your business site should be equally important as your local machines.  To assume that your business will never be exploited only exposes you to unnecessary risks that could put you out of commission effective immediately.

Three Simple Tips for Protecting Your Site

These days, it is more important than ever to keep your website current with the latest security measures.  Why so much emphasis on security?  Because hackers are always looking for ways to penetrate servers and websites to thieve sensitive information.  There are is a lot you can do to ensure better website security and the tips in this article should taken very seriously.

1.) Update Your Applications and Scripts

Running outdated web applications and code on your site is liking giving hackers an open invite.  So if you have older versions of WordPress or Joomla installed, it is advisable that you immediately check for and perform the necessary updates.  This goes for any application or programming languages used for your site.  For a knowledgeable hacker, compromising Joomla 1.0 is as easy as uploading a shell script to an insecure form.  If successful, they could end up with complete control of your account.

2.) Create Strong Passwords

A password can be a simple but effective security mechanism.  However, this is only the case when following a strict set of rules.  When securing login sessions and other areas of your site, never apply a password that can be easily guessed by others or is used for other accounts.  If someone knows just one of your passwords, they can keep trying it for each of your accounts until they are successful.  This could not only lead them to the control panel login of your hosting account, but also the financial institution you do your online banking with.

3.) Mask Your Folders

It is always wise to cloak your website files and folders that are stored on the server.  Many security experts suggest keeping a blank index.html file in each of the folders stored in your public directory.  Doing this will ensure that the contents cannot easily be viewed by internet users.  This process is made simple with the cPanel control panel and its Index Manager function.  You can take this one step further by password protecting the administrator folder that contains the scripts you are running.  This is highly recommended as it provides an added layer of security that will make an intruder have to work that much harder.

What If I Still Get Hacked?

As we eluded to earlier, there is a possibility that even after adhering to all of these tips and more, your website can still be compromised by a hacker.  Should your site be successfully exploited, there are a couple of things you should do right away to minimize the damage.  The first step that needs to be taken involves changing all of the passwords associated with your website.  This goes from your control panel and administrative areas to everything else in between.  Next, go through your hosting account to find and update all old applications and plugins as they could easily be the culprits that led to exposure.  Any website can be compromised and if it happens to you, your sensitive information can be used for criminal gain in one way or another.  Prevention is the key so employ all the measures you can to ensure you are protected against the existing and emerging threats.
