Website security risks are getting greater and greater with advanced websites. You need to check for common security problems that could leave your website vulnerable to a preventable attack. Websites now don’t consist of simple pages. People want a dynamic and interactive online experience but this comes with a number of potential security issues.
Errors on a website
When a website is built, a detailed error message shows the reason why things haven’t worked out as planned. The detailed message is allowed to be displayed on your website, can be a huge security risk. They could give away important information that an attacker could use to break into your web server.
Make sure you tidy up all error messages before you launch your site. Any errors that may appear should mean something to the people using your website, without giving away any sensitive information.
Most people know that when a green padlock appears in their web browser, it indicates that the connection is secure. Secure padlock generated by a secure sockets layer (SSL) certificate, which you have to install on the server hosting your website. All traffic sent between your web server and a user’s computer is encrypted to prevent people from reading any sensitive information.
If you don’t use SSL this could leave you vulnerable to attack. This will, in turn, lose customers due to a lack of trust. People visiting your website over a free wireless network connection is a particular problem. The information that has been sent across your network, would have been read.
Most websites have a database at their core containing information about the site, such as its content or details of registered users.
SQL injection is a method used by attackers to add extra code to a database query. This allows the hacker to access parts of the database and compromising your website. SQL injection can happen when the server doesn’t properly check information that is passed to it from the outside world.
You can use ‘prepared statements’, or a suitable alternative, to separate the data users enter from the actual structure of your database query.
Your web server should never trust information sent to it over the internet. Make sure your website runs checks on the server to ensure data isn’t malicious. Remember to consider the less-obvious sources of data that are not immediately apparent. These will be the first place a malicious user will try and break in.
There are a number of other devious methods that malicious users may employ, such as cross-site request forgery (CSRF) and clickjacking, so it’s important to take a good all-around approach to website security. Your website may be the main way you communicate with your customers. If it fails due to a malicious attack, it can be a costly experience. Even worse, if sensitive data is compromised, both your reputation and business can be irreparably damaged.
