There has been a move towards building web applications given the rising cost of mobile applications. However, one thing has remained unchanged – of according low priority to web application security testing. The consequences are quick and dire with cybercriminals targeting such applications confidently. Companies like Monsanto, Ebay, and Target, among many others bore the brunt of security breaches. The situation is not getting under control but rather worsening with each passing day.
It appears the hackers are finding it easy to break into applications and databases at will and decamping with the stolen data. If analysed properly, part of the problem seems to lie with the enterprises themselves. Their obsession with releasing web applications quickly and get ahead of the block is leaving vulnerabilities and glitches go unchecked. In fact, software application security testing is often overlooked in favor of app management, code development, and visual design.
So, as an enterprise if your priority is to be commercial with web applications, then web application security testing needs to be the priority and not ...
... an afterthought. Let us first understand the consequences of not making dynamic application security testing an integral part of the SDLC.
• Resident vulnerabilities can remain unchecked, which are exploited by hackers
• Breaches occur leading to a loss of sensitive customer and business data and information
• Enterprises may fall foul of regulatory bodies by not complying with mandatory protocols/regulations
• Enterprises may face lawsuits from affected parties (customers and clients) and served penalties causing huge financial outgo
• Brand name takes a hit, sometimes irretrievably
To pre-empt your organization from being at the receiving end of such attacks, you should strengthen the security of web applications or for that matter any software during development. Let us understand how by applying a robust application security testing methodology the security of web applications can be strengthened.
Strengthening web application security with software testing
The importance of testing cannot be glossed over any further and should be applied in letter and spirit. This can strengthen your application’ security mechanism and make it impervious to cyber-attacks.
• Penetration testing to identify the loopholes: You must know how hackers can attack your web application. This will provide you with insights on the ways to strengthen security. So, conduct penetration testing wherein professional QA testers shall attack the application to identify its loopholes or vulnerabilities. However, conduct such a testing in an isolated environment. The security penetration testing can help you learn more about the following:
o Cross-site scripting
o Cross-site request forgery attacks
o SQL injection attacks
o Broken authentication
o Insecure deserialization
• Keep a backup: It is always a good idea to keep a backup of your data. So, post any cyber-attack scenario when you need to have your website go live once again, the backup data will come in handy. No need to describe the scenario where there is no backup and a malware attack strips everything clean leaving the organization tottering on the brink.
• Implement DevSecOps: With DevOps implementation, enterprises aim at building a CI/CD pipeline where both Development (along with QA) and Operations work in close coordination and collaboration. This can be further strengthened with DevSecOps where ‘Sec or Security’ is made part of the whole system. Enterprises need to mandatorily follow a culture wherein security becomes everyone’s responsibility and not just of the QA team. As an application security testing strategy employees should scrupulously follow the Risk and Compliance manual and do not inadvertently divulge password or other details.
• Encryption is a must: Any web application has several APIs connecting various modules to third-party applications. These can be the entry points for hackers to get into the application and siphon off sensitive business and customer information. So, all conduits for data transmission within and outside the application should be encrypted. The same can be verified through software application security testing.
• Use SSL Encryption or HTTPS: Use SSL (Secure Sockets Layer) or TSL (Transport Layer Security) protocol to encrypt information in your login pages. These can protect sensitive information such as debit/credit card numbers, login details, or social security numbers, among others from falling into the hands of hackers. In addition, many browsers flag certain websites or web applications without HTTPS as insecure thereby preventing potential users from accessing them.

Conclusion
The security testing of web applications is of prime importance, like any other software, as it will help enterprises to secure their deliverables and earn trust from the end customers. In the competitive world of business, it is trust that will keep any company in good stead vis-à-vis its equation with customers and competitors.
