Web Application Security Risks & 9 Best Practice Tips

White-box testing will give you a list of clear gaps, ambiguous vulnerabilities, and code that might lead to an attack somewhere down the line. Start by creating a comprehensive list of these issues that make it shareable within the organization. Developers are often aware of flaws when they are building a product but compromise for the sake of functionality and time management. The collective intelligence of your organization will lead to a detailed list that is closed to being exhaustive.

Get rid of ones that don’t actually make any difference to your app and update everything that remains. At the very least, build an update strategy, as updating libraries sounds easier than it actually is. Many developers hesitate to update third-party services for their software because newer versions may lack backwards compatibility and mess up the whole system. Finally, remember to regularize web application security as part of your larger compliance plan.

These tools help us effectively prioritize the API risks that present the most danger to the organization. A WAF is a security tool that monitors and filters incoming traffic to a web application. It helps protect against common web attacks, such as SQL injection, cross-site scripting , and cross-site request forgery , by inspecting the incoming traffic and blocking malicious requests.

Web application developers can use Snyk within their existing workflows to scan code and open source components for vulnerabilities or misconfigurations. Our comprehensive vulnerability intelligence database is curated by Snyk’s security experts and is the most comprehensive on the market. Static application security testing tools such as Snyk Code scan code against predetermined best practices to identify problematic code patterns. Web application security tools like firewalls and scanners are effective in detecting cyber threats. But sometimes, they are unable to pick up threats until they become significant. If you are aware of your cybersecurity needs, there’s a chance that you have implemented some cybersecurity measures.

It occurs when binding happens without using properties filtering based on an allowlist. It enables attackers to guess object properties, read the documentation, explore other API endpoints, or provide additional object properties to request payloads. Instead, you should check object level authorization in every function that can access a data source through user inputs. Installing software updates and patches is one of the most effective ways to keep your software secure. Why try to solve problems yourself if something has already been remedied?


Additionally, Perimeter 81 also encrypts all stored information and filters out outbound traffic. A web application security solution seeks to protect businesses from all attempts to exploit a code vulnerability in an application. In order to ensure that your web application has 24/7 protection, you need more than just a security audit to identify and fix all of its vulnerabilities. If the web application executes the file, it may expose sensitive data or even execute malicious code.

A third-party professional will not only test your web app but conduct a full security audit of it while performing penetration testing. Implement SSL encryption for all user data you send to and receive from the server. While HTTPS is great and makes man-in-the-middle attacks nearly impossible, it’s not enough if somebody has access to your server.

An example of an XSS attack is when a hacker exploits an input field’s vulnerability and uses it to inject malicious code into another website. Learn about the software development lifecycle and how to integrate security into all stages of the SDLC. If insiders go bad, it is important to ensure that they never have more privileges than they should—limiting the damage they can do. Hackers might compromise less privileged accounts, and it is important to ensure that they cannot gain access to sensitive systems.

Why You Need an Effective Web Application Security

The OWASP Top 10 ranking outlines the most critical security threats to modern online applications, organized by perceived significance. This is the first revision to the list in five years, with the last one being published in 2017. The OWASP Top 10 is designed to help businesses avoid these security risks and protect their online applications.

Additionally, scanning tools like Snyk IaC can detect and remediate misconfigurations before they reach production environments. They use malicious techniques to gain unauthorized access to the information that users input in a web application. It suffices to say that if you are using web 2.0, you have to prioritize your cybersecurity. With comprehensive in-app encryption, it’ll provide the highest level of security for both managed and unmanaged apps.

You can remediate this issue by implementing strong access mechanisms that ensure each role is clearly defined with isolated privileges. DevSecOps is DevOps but with security as an additional integral part of the automated CI/CD processes. “Companies should try to enforce that — so not just hope that the developers would use that, but also implement DevSecOps,” Sotnikov said. WhiteSource, said companies these days rely on countless dependencies, and that can cause problems if even a couple have security flaws or are not current with the latest patch. That can be especially dangerous, because once the security flaw prompting the patch is made public, anyone can target older versions of the tool that still have the flaw. Applications that have not upgraded to the latest version could be more at risk than before.

Scan for Vulnerabilities – With the right tools in place, this is one of the most effective ways to ensure the security of web applications. Performing continuous scans makes it easier for organizations to identify the vulnerabilities they’re exposed to. Orca’s vulnerability management tool, which covers every layer of your cloud, including cloud workloads and configurations. It combines all this information into a unified data model to prioritize risks and recognize when seemingly unrelated issues can be combined to create dangerous attack paths. This is a simple step that doesn’t require complex web application security tools but is often overlooked by organizations. Attackers will take advantage of any unencrypted HTTP requests and mislead users.


Citrix Workspace app is the easy-to-install client software that provides seamless secure access to everything you need to get work done. Implement an x-xss-protection security header to defend your web app from cross-site scripting. Your plan should contain a classification of attacks, and for each type it should have a list of actions and a time frame within which they should be completed. Not only should you have an emergency plan, you should also test it regularly to make sure your systems work properly and your employees react quickly and effectively.

The WAF serves as a shield that stands in front of a web application and protects it from the Internet—clients pass through the WAF before they can reach the server. Use security systems such as firewalls, web application firewalls , and intrusion prevention systems . However, it is always worth being more protected than the rest and doing your utmost to minimize the number of errors in your applications in order to make you a more challenging target to exploit.

  • With comprehensive in-app encryption, it’ll provide the highest level of security for both managed and unmanaged apps.
  • By using a WAF, you can enhance your web security protection and performance, and complement your other web security standards and frameworks.
  • Normal modules – Normal modules don’t have direct access to sensitive information in your app but also require attention and constant checkups.
  • Web application vulnerabilities allow bad actors to gain unauthorized control over the source code, manipulate private information, or disrupt the application’s regular operation.
  • By using this form you agree that your personal data would be processed in accordance with our Privacy Policy.

This makes it difficult to gain visibility over a cloud native environment and ensure all components are secure. While automated tests manage to catch most security issues prior to release, there may still be potential gaps that have gone unnoticed. To minimize this risk, it is worth employing an experienced pentester to test the application. This type of ethical hacker attempts to break into the application in order to detect vulnerabilities and find potential attack vectors with the aim of protecting the system from a real attack. It is important that the pentester be an external expert who is not involved in the project. Developers working on applications should be trained on the Open Web Application Security Project’sOWASP Top 10 and the SANS Institute’sSANS web application security checklist.

If security is reactive, not proactive, there are more issues for the security team to handle. Snyk scans your code for quality and security issues and get fix advice right in your IDE. Identification and Authentication Failures – Slid from the second position in the 2017 Top 10 list but remain a common vector for attacks. Sometimes, an honest mistake by you or someone on your team could compromise your network. The high engagement on web 2.0 means that visitors to your website can enter their personal information for their browsing needs. It’s your responsibility to secure your visitors’ confidential information from attackers who would want to access it.

What is application security testing?

If your database stores information about your users, that’s reason enough to protect your software and eliminate any security issues. According to Security Magazine, a cyber attack takes place somewhere in the world every 39 seconds. As hackers become hungrier for people’s sensitive data and the number of cyberattacks increases, it’s vital to ensure reliable protection of your web app. – We included Detectify on this list for its dedicated tool for small businesses. Today, every small business must have an online presence, but they often lack the internal teams to maintain a secure web presence. Detectify scans web applications for 2,000+ security test cases, including and beyond OWASP.

In this article, I’ll be talking about application security best practices. I’ll talk about overall cybersecurity strategies and small things that make a difference. According to Corero, a single DDoS attack can cost a company around $50,000 in lost revenue. Losses in the case of a security breach include not only the personal data of your users but, more importantly, users’ trust in your business. And lost trust leads to even more significant financial and reputational losses. Learn how to prevent sophisticated attacks such as SQL injections, broken authentication, server attacks, cross-site scripting, session management, and other hidden threats in this whitepaper.

It is important to measure and report the success of your application security program. Identify the metrics that are most important to your key decision makers and present them in an easy-to-understand and actionable way to get buy-in for your program. 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. This way, security testing doesn’t get in the way when you release your product. CNAPP technology often incorporates identity entitlement management, API discovery and protection, and automation and orchestration security for container orchestration platforms like Kubernetes.

Changing passwords frequently, locking devices, and keeping software up-to-date are all common security practices. However, an application’s security can often be an ignored and vulnerable element. Learn about security testing techniques and best practices for modern applications and microservices. Vulnerabilities are growing, and developers find it difficult to address remediation for all issues. Given the scale of the task at hand, prioritization is critical for teams that want to keep applications safe.

Great Companies Need Great People. That’s Where We Come In.

Web apps are also vulnerable to cyber threats if developers don’t know versions of used components in the back-end and front-end. Besides, this defect arises when components are unsupported, outdated, misconfigured, or irregularly examined for vulnerabilities. This failure should be distinguished from development-related flaws which arise during the project development process. Even no matter how the development process is perfect, products with insecure designs are prone to attacks. This is because developers are not well-instructed to build essential security controls. Follow these eleven web development security best practices if you want to keep your business and reputation free of malicious hacker attacks.

It enables attackers to exploit an implementation flaw or compromise authentication tokens. Once it occurs, attackers can assume a legitimate user identity permanently or temporarily. As a result, the system’s ability to identify a client or user is compromised, which threatens the overall API security of the application. Security logging and monitoring failures (previously referred to as “insufficient logging and monitoring”) occur when application weaknesses cannot properly detect and respond to security risks. When these mechanisms do not work, it hinders the application’s visibility and compromises alerting and forensics.

Web Application Security Explained: Risks & Nine Best Practices

Insecure Design – Consists of poor or absent control design, such as generating error messages that contain sensitive data. If you aren’t the only one on your team, how the others engage with your web application can either make or mar its security. As the owner or project manager, it’s your responsibility to bring everyone up to speed on healthy web application practices. Encrypting your web application secures the information shared from the user’s browser to your server. Make sure that the data is not only encrypted at rest but also in transit. You can use SSL/TLS encryption to secure interactions of your web application through the HTTPS protocol.
