Security Testing for Critical Applications

Security Testing Services has been picking a lot of deserved momentum in the recent years. Organizations are very particular in ensuring applications are tested for non-functional areas too – especially app security, performance, accessibility, before going live. Mostly short test passes, security testing is taken up by a group of subject matter experts who test the application ethically for various vulnerabilities, to ensure the application is mitigated, should security attacks arise.

As an organization that provides specialized security testing services, we have a group of SMEs that focus on both security testing for products as well as take up constant R&D to ensure we stay current with the latest threats in the STRIDE set. While security testing is important across all digital solutions, it is particularly important in domains that deal with critical user data and user assets, including health care, BFSI amongst others. Let’s take testing banking applications for security for example. It deals with sensitive user information and assets, often becoming a target for attacks that makes it a highly regulated industry. While there aren’t specifics that related to security testing specific to domains, there are a few core practices that help:

  1. Look beyond the core OWSAP Top 10 vulnerabilities, as attacks can be much deeper than just a web UI level
  2. Get into security testing at the web services and database layers to catch deeper issues early on
  3. Stay hands on with the functional workflows and prioritize the critical workflows to scrutinize them for security. Herein a paired approach of a security SME with a domain expert will certainly help in case the security tester lacks domain knowledge given his/her breadth of working across products
  4. Learn continuously. Continue to look for security defects that are domain specific to broaden your test scope – herein there is wealth of information online that talks about ongoing attacks, which gives you ideas for what to additionally look for, besides your core tests. For example, this link, talks about severe defects that continue to impact global organizations and users – this includes the testing banking applications too. Herein sometimes, the issue may not be security related to banking, but a functional issue in the banking industry that may very well be extrapolated and be applicable from a security angle
  5. In essence, what is needed is to be hands on, current, creative and out of box, especially when dealing with security testing for critical applications.

Such ongoing evolution, will give users additional confidence to transact online, organizations to venture into digitization of critical paths and regulating bodies to relax bounds making it a win:win situation for one and all. At this niche level, security testers, especially for critical applications need to work closely with developers, designers, stakeholders in ensuring that quality becomes everyone’s responsibility and they are able facilitators in drive this collective ownership.

We, at QA InfoTech, have been helping organizations across domains secure their applications for years now. Some have been backed by federal mandates, some from the organization’s responsibility in releasing vulnerability mitigated applications, some which are a mix. These projects continue to enrich our experience repertoire, wherein we evolve our test suite with every single product that we work on, especially for areas such as security where the learning is endless.
