Proud of your Drupal Website?
Well, I’m sure you are. But what about the security aspect? Are you sure it will not be compromised? Many times it is seen that site owners remain oblivious of the threat perception to their Drupal website on the assumption that there is nothing ‘worthy’ in the site for hackers to attack.
However, this is utter ignorance as hackers follow no rules. Most security intrusions happen not just with the intent to steal data or ruin your website, but instead as an attempt to use your server as an email transmit for spam; or to setup a temporary web server – usually to serve files engaged in unlawful activities.
Here in this article, we will be discussing the security measures that can be adapted to secure your Drupal websites from hackers.
Tip #1. Always Keep Your Software Updated
Keeping your software updated is one of the simplest yet assured way to secure your website from being hacked. And this applies to both the server operating system as well as any software you may be running on your website such as a CMS or forum. Remembers, hackers are on the lookout for security breaches in your software, so as to attempt a hack.
Solution: Always ensure that the software for your Drupal website is updated.
Tip #2. Beware of SQL injection
Beware of SQL injection attacks as this is one of the most treaded path that hackers use via a web form field or URL parameter so as to gain access to or manipulate your database. This mostly happens when you use standard Transact SQL whereby you unsuspectingly insert rogue code into your query. These are actually used by hackers to change tables, get information and delete data.
Solution: This situation can be easily averted by making sure that you always use parameterized queries. Most web languages have this feature and it is also easy to implement.
Tip #3. Be Wary of Sharing information in Error messages
In case you have a login form on your website, be careful about the language you use while communicating failure when attempting logins. Using generic answers for error messages is a preventive option to ensure site security so that the hacker is clueless about whether they have managed to get a section of the query in a field right.
Solution: Use generic messages and make sure to keep your error messages vague.
Tip #4. Beware of Cross Site Scripting
Solution: Always ensure when creating a form, to check the data being submitted and encode or strip out any HTML.
Tip #5. Monitor File Uploads
File uploads by users (even if as simple as changing avatars) can pose to be a big risk on security of your Drupal website because, there remains risk of (rogue) files containing a certain script, which when executed on your server holds the risk of opening up of your website completely.
Solution: You will have to ensure that users are not able to execute any file they upload. Even though it is generally believed that web servers (by default) will not attempt to execute files with image extensions, you cannot rely solely on this assumption because a file with the name image.jpg.php can create a problem.
