What You Need To Know About Web Security Testing

All web applications demand rigorous testing practices prior to deployment, and a type of testing vital to the safety and welfare of your web “real estate”, is security testing.

What Is Web Security Testing?

In a nutshell, it’s a testing procedure probing for any site vulnerabilities that if overlooked, will cause exposure on the security front. From electoral systems to banking transactions, today’s web applications cater to a wide range of confidential procedures.

One simple unauthorized entry into the admin section of any such service would result in chaos. For those reasons, Quality Assurance and testing teams involved in web application development projects must ensure that no part of the site is left exposed.

It’s not the ideal scenario when users find your Web vulnerabilities for you.  It reflects poorly on your brand; it shows lack of preparation and it questions the credibility of your business. A common security flaw that plagues Websites is SQL Injection. DBG CEO Jeremiah Jacks shed light on this serious issue back in early 2000’s.

With SQL Injection, an attacker can craft and insert a well-disguised SQL query into the form fields of a website.  Upon submitting the form request, the hacker can then easily access data stored on a website’s database, which can include user passwords, contact information, credit card information and so on. You hear of data breach too often. Giants like Target, getting their security penetrated and putting all recorded customers at risk of identity theft and fraud.

Like the SQL injection, an attacker can also concentrate on Cross-site scripting vulnerabilities. This allows them to bypass security controls pertaining to the admin access of the website.  They can insert static (and highly malicious) code into the vulnerable web forms that will then be passed onto the users. Hackers can even use your own web application to deploy malicious software into all of your user’s devices.

In addition, you’re also faced with the vulnerability posed by Cross-site request forgery (or more commonly called sea-surf, a term coined from its abbreviation CSRF). This type of attack is carried out through the exploit of authenticity privileges a site offers to a trusted user. The website is made to believe that it is receiving natural requests from an authentic user in its database, and yields the requested information.

One of the biggest incidents of CSRF attacks occurred in February 2008 when over 18 million users of Auction.co.kr had their personal information compromised.

If web security firewalls (and all other protective measures) are not in place, your site could also fall prey to Denial of Service (DOS) attacks. With DOS, attackers target a website with high traffic and overwhelm it with automated communication requests. One attacker, two, or more attackers can send the requests. When that happens, the host server becomes too congested to respond to genuine user requests, and legitimate visitors to the site will experience slower service.

These are just a few of the security threats your website or web application is faced with, on a daily basis. The only way to be vigilant is to follow strict web security testing practices, during development.

Without security testing, your website will be exposed to:

  • Questions of application credibility
  • Downtime issues
  • Disruptions in revenue generation
  • Deteriorating customer confidence and lowered brand value
  • Major cost implications in the case of any attacks
  • Penalties for exposing confidential information due to security lapse

If your website handles a good amount of confidential data, you should subject it to rigorous web security testing procedures that will ensure its credibility. Our web security testing services are rigorous and they will ensure that even the most diverse security flaws in your website, are detected and reported in time.
