Web application security refers to practices associated with preventing malicious attacks against online apps. Free vulnerability scans provide a starting point; however, sophisticated online criminals have learned to stay ahead of the databases on which these free tools rely.
Some paid scanning software relies on a frequently updated database of known attacks and artificial intelligence that can send alerts based on suspicious behaviors. However, a full penetration test can uncover web app vulnerabilities by combining high-tech vulnerability scans and the insights of trained security professionals who will mimic today's hackers' actions and strategies. These insights reveal hidden vulnerabilities, providing an action plan to remediate your web app security weaknesses before digital criminals can exploit them.
As the name implies, web application vulnerabilities refer to security flaws in online applications. Web applications may be prone to security weaknesses because they provide sensitive data and are developed for multiple users across various platforms. Also, even though web apps may require login credentials to access, hackers can typically find the login pages and information about the app on the open internet.
According to recent research from Verizon, attacks on web applications made up 39% of all breaches, making it a top attack pattern for organizations operating their business functions in the cloud. With the rise of remote work and the increased popularity of conducting business online, malicious users' number of opportunities to breach digital apps also increased. Some common examples of web application security threats include:
Penetration testing uses application-specific vulnerability scans and highly trained people who can emulate the actions of hackers. These tests will uncover existing security issues and provide an action plan to address them, allowing organizations to remediate existing problems and develop policies to prevent new ones.
Web application security testing particularly matters in light of Edgescan categorizing almost thirty-five percent of all internet-facing security vulnerabilities as high risk. Internal, intranet applications fared even worse. Over 40 percent of security issues for internal software earned a high-risk classification. If a malicious hacker can exploit these vulnerabilities, they can steal sensitive data, take down critical systems and, almost always, damage a company's reputation.
Besides choosing methods and tools for testing web app security, organizations should consider including these suggestions in their testing plans:
Secure organizations use these kinds of web application security testing to uncover vulnerabilities:
Often called DAST, dynamic application security testing looks for security weaknesses that attackers might exploit. Because DAST tools don't need to examine source code, this method offers a good solution for frequent, fast testing.
SAST methods and tools must comb through source code to take longer than DAST methods. On the other hand, SAST can pinpoint security issues down to the exact lines of code. As a result, organizations might use SAST with new development on systems that have never been scanned before and after modifying existing apps. However, no tool is perfect, and manual review is always recommended.
Although some scanning software utilizes machine intelligence to pick up on novel threats, these tools rely on a database of known threats and typical attack behavior. With web application penetration testing, a skilled security professional will approach an application the same way a sophisticated hacker would. These pen testers can uncover potential exploits that scanners miss. They can also provide action plans to remediate problems.

According to a recent Forrester Research survey, 42 percent of organizations blamed discovered security holes on insecure applications. Of these, hackers most commonly targeted web applications. The survey respondents said that flawed environments or buggy source code accounted for more external security problems than any other single issue.
To protect themselves from these threats, organizations develop application security testing programs. These programs provide a process that businesses can use to assess and address threats continually. They also help companies acquire the necessary information to balance risk levels against resources and prioritize tasks to remediate problems.
Security teams must work with user departments and third-party providers to develop, implement, and maintain their security testing program. Everybody involved needs to prioritize security as a non-negotiable functional requirement at the start of a project. Just as important, stakeholders must ensure they maintain vigilance throughout the project's lifetime. A business that has already relied upon an application for years doesn't offer assurance against new security threats.
An effective testing program will help spot security weaknesses and provide the information needed to reduce the risk of exposure to threats before they occur. A practical application security testing program should:
The many benefits of web apps have attracted businesses' attention; however, these apps' vulnerabilities have also gained hackers' eyes. No company wants to take unreasonable risks with their business security. Attackers can exploit security issues to steal valuable information, take over essential systems, and cause irreparable, reputational damage. By testing web applications, organizations can significantly reduce risks and preserve the value of their online assets.
