Securing Your Website: How to Plug Holes in the Web Design

It doesn’t matter anymore whether you have a personal blog or a multimillion dollar eCommerce website, if you have a web presence, it is likely to get hacked at some point or another. While there is no absolute way to plug all security holes forever, here are a few important tips for both web designers and website owners to keep it as secure as possible.

Understanding and Preventing the SQL Injection

SQL (structured query language) injection is a method of gaining illegal access to a website’s database, through injecting malicious codes into the site’s URL. It usually happens on websites that use standard Transact SQL, ending in the hacker gaining access to sensitive information, which they then proceed to change or manipulate otherwise, to suit their needs best.

Utilization of parameterized queries is the best way to counteract the SQL injection threat, and you can find out more about it here.

Use a Digital Forensics Software to Detect Vulnerabilities

Digital forensics is famous for tracing a hack to its roots, detecting the vulnerabilities through which the malware managed to get through and even identify the possible cybercriminals associated with the crime. However, what most businesses do not know or realize, is that they can download a free computer forensics software as a prevention tool to spot design vulnerabilities even before anything happens.

The free computer forensics software from Secure Forensics helps businesses secure their systems and websites in advance, so a visit to their page will clarify any and all questions regarding how to use the free computer forensics software to close gaps ahead of a disaster. In general, you can expect a digital forensics team and their software to help in the following ways:

  • They track cybercriminals and keep the company updated about malware releases before or as soon as they happen
  • Digital forensics software can detect security gaps in the web design, or that of a software utilized by the company, before it can be exploited

Preparing for and Preventing XSS Attacks

XSS attacks, also known as cross-site scripting, is not that dissimilar to SQL injection, but it outs unauthorized JavaScript in the webpage, allowing the hacker to steal information from every user who is logged in, including the cookies that save the login information of your users.

Adopting a Content Security Policy (CSP) works pretty well to defend against XSS threats, as it’s a header that the server can return, instructing the browser regarding JavaScript execution policies and limiting the chances of unauthorized XSS executions in the process.

Reconsider File Upload Permissions for Users

It is common for websites to allow uploading of a profile picture for user accounts, but users can, under no circumstances, be allowed to execute anything that has been uploaded onto your website.

Malicious files can easily be disguised as image files, so the best way would be to restrict all access to any data uploaded by any user. They should only be able to upload and delete.

This isn’t a comprehensive list of course, but it will get you started on making your website more secure, and you will recognize the other requirements along the way.
