Application Security AppSec: Threats, Tools, and Techniques

Application security is the process of developing, adding, and testing security features within applications to prevent security vulnerabilities against threats such as unauthorized access and modification. A cloud native application protection platform (CNAPP) provides a centralized control panel for the tools required to protect cloud native applications. It unifies cloud workload protection platform (CWPP) and cloud security posture management (CSPM) with other capabilities. It involves identifying, classifying, prioritizing, and mitigating software vulnerabilities. Vulnerability management tools scan your applications for known vulnerabilities, such as those listed in the Common Vulnerabilities and Exposures (CVE) database.

In this context, a threat is any potential or actual adverse event that can compromise the assets of an enterprise. These include both malicious events, such as a denial-of-service attack, and unplanned events, such as the failure of a storage device. Companies are transitioning from annual product releases to monthly, weekly, or daily releases. To accommodate this change, security testing must be part of the development cycle, not added as an afterthought.

Software security testing best practices

Security misconfiguration flaws occur when an application’s security configuration enables attacks. These flaws involve changes related to applications filtering inbound packets, enabling a default user ID, password or default user authorization. The CWE list focuses on specific issues that can occur in any software context. Its goal is to provide developers with usable guidance on how to secure their code. Firewalls determine how files are executed and how data is handled based on the specific installed program.

You also need the agility to quickly come out with a patch if a user or bug-hunter reports a security flaw. Learn about cross site request forgery (CSRF) attacks which hijack authenticated connections to perform unauthorized actions. You can remediate this issue by implementing strong access mechanisms that ensure each role is clearly defined with isolated privileges.

Why application security is important

Static application security testing (SAST) is used to secure software by reviewing the source code of the software to identify sources of vulnerabilities. A variety of application security testing tools exist to assist teams with securing their software. Deciding which tool is right for you of course depends on the type of tests that need to be conducted.

SAST tools use a white box testing approach, in which testers inspect the inner workings of an application. Today, due to the growing modularity of enterprise software, the huge number of open source components, and the large number of known vulnerabilities and threat vectors, AST must be automated. Application security testing (AST) is the process of making applications more resistant to security threats, by identifying security weaknesses and vulnerabilities in source code.

A router that prevents anyone from viewing a computer’s IP address from the Internet is a form of hardware application security. But security measures at the application level are also typically built into the software, such as an application firewall that strictly defines what activities are allowed and prohibited. Procedures can entail things like an application security routine that includes protocols such as regular testing. A testing methodology that combines the best features of static application security testing (SAST) and DAST, analyzing source code, running applications, configurations, HTTP traffic and more. MAST tools employ various techniques to test the security of mobile applications. It involves using static and dynamic analysis and investigating forensic data collected by mobile applications.

Be proactive about app permissions

Finally, the vulnerabilities are mitigated, often through patch management procedures. Investigate what are the main entry points attackers can use to breach your applications, what security measures are in place, and whether they are adequate. Set reasonable goals, and milestones over time, for the level of security you want to achieve against each type of threat. However, the Open Web Application Security Project (OWASP) Top 10 list compiles the application threats that are most prevalent and severe, and most likely to affect applications in production. Continuous testing in every stage of the development life cycle is crucial, but these additional tips can help developers secure their applications at all times. Forrester found container security to be a priority during application deployment (37%) and design (20%).

  • MAST tools combine static analysis, dynamic analysis and investigation of forensic data generated by mobile applications.
  • In 2015 in the U.S. alone, users spent 54% of their digital media time on mobile devices actively using mobile apps.
  • Application developers perform application security testing as part of the software development process to ensure there are no security vulnerabilities in a new or updated version of a software application.
  • It can affect firewall-protected servers and any network access control list (ACL) that does not validate URLs.
  • DAST focuses on inputs and outputs and how the application reacts to malicious or faulty data.

The goal of an AST program is to reduce the number of vulnerabilities in the organization’s applications before they can be exploited and to mitigate the potential impact of undetected vulnerabilities. Beyond vulnerability detection, AST can also help identify root causes of vulnerabilities, provide insights into the organization’s security posture and help to establish compliance to regulations. MAST tools combine static analysis, dynamic analysis and investigation of forensic data generated by mobile applications. They can test for security vulnerabilities like SAST, DAST and IAST, and in addition address mobile-specific issues like jailbreaking, malicious wifi networks, and data leakage from mobile devices. Application security controls are techniques to enhance the security of an application at the coding level, making it less vulnerable to threats.

Once this is ready, you can roll out patches to keep them secure or remove redundant apps to cut down vulnerabilities at the root. Most organizations require some level of personally identifiable information (PII) or personal health information (PHI) for business operations. Information such as social security number, tax identification number, date of birth, driver’s license number, passport details, medical history, etc. are all considered confidential information. VAPT simulates the real-time systems and helps the user to find out if the system is accessed by an unauthorized user or not. In addition, the report stated that attackers targeted web applications to leverage the benefit of financial and personal information from victims’ devices.

Testing methodology that depends on ethical hackers who use hacking methods to assess security posture and identify possible entry points to an organization’s infrastructure — at the organization’s request. Security professionals use different tactics and strategies for application security, depending on the application being developed and used. Application security measures and countermeasures can be characterized functionally, by how they are used, or tactically, by how they work.

They’ll try various techniques like SQL injection, URL manipulation, spoofing and cross-site scripting (XSS). When they find a weakness they’ll attempt to exploit it to breach the organization’s defenses and perpetrate their attack. Over 80% of breaches involved the use of stolen credentials and a prime target was web servers storing sensitive information. To secure an application, it’s important to use application security testing tools, which scan applications for specific security vulnerabilities to identify and prevent cyberattacks. When a security issue is found, the application security testing tool notifies the developers so they can remediate the issue. Application security testing (AST) is the process of making applications more resilient to security threats.

Given the scale of the task at hand, prioritization is critical for teams that want to keep applications safe. Organizations use SCA tools to find third-party components that may contain security vulnerabilities. APIs usually do not impose restrictions on the number or size of resources a client or user is allowed to request. However, this issue can impact the performance of the API server and result in Denial of Service (DoS). Additionally, it can create authentication flaws that enable brute force attacks. The most severe and common vulnerabilities are documented by the Open Web Application Security Project (OWASP), in the form of the OWASP Top 10.

When it comes to open source vulnerabilities, you need to know whether proprietary code is actually using the vulnerable feature of open source components. If the function of the vulnerable component is never invoked by your product, then its CVSS rating is significant, but there is no impact and no risk. SCA tools create an inventory of third-party open source and commercial components used within software products. It helps learn which components and versions are actively used and identify severe security vulnerabilities affecting these components. Cloud native applications are applications built in a microservices architecture using technologies like virtual machines, containers, and serverless platforms. Cloud native security is a complex challenge, because cloud native applications have a large number of moving parts and components tend to be ephemeral—frequently torn down and replaced by others.
