Web Application Security Best Practices

As mentioned previously, it is preferred to plan on failure and use multiple least privilege accounts to limit the blast radius for when a failure does occur. Whenever privileged access is required, ensure that very strong authentication controls are established (e.g, multi-factor authentication only from internal network) and thorough auditing is in place. In this post, we will list seven of the most important web application security best practices that you should follow to protect your apps from threats.

Suffering a cyber incident often means compromised user accounts, derailed customer trust, damaged brand reputation, loss of sensitive data, loss of revenue, and a whole lot more. A recent IBM report indicates that the average costs of a data breach in 2021 stood at an astounding $4.24 million, which for smaller businesses can threaten their very existence. Most mainstream content management systems and open-source applications offer these notifications natively or through plugins.

Web Application Security Practices to Protect Data

Without comprehensive logging and monitoring of applications, attackers can perform reconnaissance of applications, attempt intrusion, and eventually find a way to bypass security controls. Monitoring enables security teams to detect these activities and mitigate the threat. Security misconfiguration—some web applications have security controls in place, but do not properly configure them. Failure to ensure secure configuration can expose the application to attack. It’s common knowledge that a large part of your web application security relies on your hosting service provider and its security practices.

ASTO not only coordinates and automates tools, but also makes it possible to manage their data and insights in one place. This allows organizations to track all potential risks more easily and resolve them more quickly, without needing to switch between multiple consoles and dashboards. Injection—a common threat vector is the injection of malicious SQL statements, operating system commands, LDAP configurations, etc.

Do not store your backups on the same server as your website; they are as vulnerable to attacks too. If you are a business owner or CMS manager, ensure all employees change their passwords frequently. Updates often contain security enhancements and vulnerability repairs. Some platforms allow automatic updates, which is another option to ensure website security. A 2019 report by Google Registry and The Harris Poll showed that even though more people are creating websites, the majority of Americans have a significant knowledge gap in regards to online security safety.

Api Security Management

XML External Entities —improper processing of XML documents, which allow attackers to create malicious references to external entities. XXE attacks can result in exposure of sensitive data on servers, internal port scanning, and denial of service . At Liquid Web, we have over 24 years of experience helping customers resolve web security problems and prevent further attacks. Our dedicated server hosting and cloud servers come pre-configured with basic security measures, and more advanced protections are also available.

How can the security measures be maintained along with good customer experience? To test for this vulnerability, you should try all the common HTTP methods as well as a few uncommon ones. TRY sending an API https://globalcloudteam.com/ request with the HEAD verb instead of GET, for example, or a request with an arbitrary method like FOO. You should get an error code, but if you get a 200 OK response, then your API has a vulnerability.

You can also use our dedicated security advisory services and tools to maintain app security on an ongoing basis. Automated Dynamic Application Security Testing and Static Application Security Testing tools should be used throughout the development lifecycle. Each has their own strengths and weaknesses but by combining their use, you get early issue identification that allows for rapid and cheaper fixes. By integrating these into your lifecycle, you get the additional benefit of maintaining a higher level of security awareness. You may use either approach and sometimes it is helpful to use both to get different perspectives on the application’s threats.

This needs to be over and above an already securely-designed web application. (Percentages represent prevalence in the applications tested.) The rate of occurrence for all the above flaws has increased since Veracode began tracking them 10 years ago. Another area seeing more vulnerabilities emerge according to the Imperva report is in content management systems, WordPress in particular.


You absolutely cannot rely on your ability to judge character to protect yourself from these attacks. Liquid Web’s Server Secure Plus includes remediation support for our customers to help determine the root cause, find website malware, and perform cleanup or restoration. A data breach occurs whenever an unauthorized user gains access to your private data. They may not have a copy of the data or control it, but they can view it and possibly make changes. High Performance Multi-server hosting solutions to reduce latency and prevent downtime.

Web Application Security Practices to Protect Data

By running on same server as the application, RASP solutions provide continuous security for the application during runtime. For example, while developing an online banking application or an online shopping website, a tight hold on the security measures from the very beginning is necessary. Like you might unintentionally let a secret slip when telling a story to a friend, it’s possible for an API response to expose information hackers can use.

User Authentication Test

There are several web application security best practices that you can follow to achieve this. These web application security best practices ensure that there are multiple layers of security incorporated in your app and development and testing processes. RASP provides deep inspection and protection, which many argue reduces the importance of SAST, DAST, and IAST. Instead of having to modify Web Application Security Practices to Protect Data applications to remediate security vulnerabilities, which is complex and time consuming, RASP can protect applications and prevent exploitation of those vulnerabilities. However, RASP cannot substitute for a comprehensive DevSecOps process and early detection of security vulnerabilities. Web application firewalls work like a proxy server between the application server and its users.

Cross-site scripting is another type of injection attack enabling attackers to inject client-side scripts into web pages that are being viewed by other users. XSS is used by the attackers to breach access controls such as the same-origin policy. In Injection attacks, untrusted data is supplied to a code interpreter through form submission or any other input source to a web application.

Viega & McGraw, OWASP , NIST , NCSC , Cliff Berg’s set are the few names comprising the collection of security design fundamentals. That means the security of REST API’s depends on the design of the API itself or an API gateway. Software developers may follow different architectures to build an API.

Critical Application Security Risks

If attackers know the tool’s default, they could easily get into the application. Existing tools and libraries are only secure as long as they are kept up to date. Maintainers of those tools may be diligent about patching new security vulnerabilities, but that won’t help if developers are still using older versions. XE can result in a denial-of-service attack by injecting entities within entities, which affects the server‘s utilization and a server shutdown.

Web Application Security Practices to Protect Data

Allows a hacker to bypass the authentication or authorization of the web application. Every three years, the Open Web Application Security Project releases its report on the Top 10 web application vulnerabilities. Organizations are encouraged to submit data to the project until July 20, 2016.

So, let’s take a look at these app security best practices and why they are important. Application security is the process of making apps more secure by finding, fixing, and enhancing the security of apps. Much of this happens during the development phase, but it includes tools and methods to protect apps once they are deployed.

Some companies hire penetration testers to test an application’s security robustness. Password manager tools give companies finer control over who has access to which passwords, and also prevent sensitive passwords from getting out by being forwarded in an email or on a slip of paper. Setting up authentication for web applications, for example, requires many customizations and configurations. An example of this type of mistake is forgetting to change the default account that a security tool comes with, Martin said.

However, remember that at the root of this work is a duty to protect your users — this extends to those who entrust you with their data, plus developers utilizing your API. With an API management platform, you can secure all your APIs and endpoints across environments and vendors in one place. An API request is only processed once its contents pass a thorough validation check — otherwise, the request should never reach the application data layer. Software development and security are constantly changing — ultimately, the best protection against security vulnerabilities is educating oneself and keeping up with changes in the field. Sometimes it can be helpful to get fresh eyes on a company’s security practices.

Api Security Best Practices

If your website is not secure, it can become low-hanging fruit for cybercriminals. For instance, an IT-focused website published an article about 90 of the biggest hacks and data breaches in 2020 a lot of which could have been prevented if they had better security in place. You need to view website security holistically and approach it with a defense-in-depth strategy. The benefit of such apps is that intrusions or malicious actions are detected in real-time, which allows you to take immediate action.

Remove Old Applications

This script is intended to expose or delete data, plant false information, and/or harm the application’s internals. You’ll also see the term “SQL injection” used — this is a code injection performed on a SQL database. API security is the practice of protecting APIs from cyberattacks and misuse. It contains features for managing authentication, authorization, data protection, HTTPS enforcement, XSRF/CSRF attack protection, and CORS management. These security features help to build robust and secure web applications.

Aqua’s full lifecycle security approach provides coverage for all clouds and platforms, integrating with enterprises’ existing infrastructure and the cloud native ecosystem. Use the principle of least privilege to ensure that each user has access to only the data and systems that are absolutely necessary for them to complete the task. Ensure CI/CD tooling uses multi-factor authentication and is closely monitored to detect anomalous behavior.

Ways To Address Security Concerns

For this, you need to develop attack-aware apps that can detect intrusions or unusual activity immediately and either notify the security operations center or take automated action. Many times developers are more knowledgeable of what standard behavior is and have more capabilities to detect malicious behavior. A standard user story for teams should be to detect malicious behavior.

Even in the online world, owners must keep customer information safe. There are at least ten essential steps you can take to improve website safety before it is too late. No method can guarantee your site will forever be “hacker-free.” The use of preventative methods will reduce your site’s vulnerability. There are many ways to assure yourself, employees, and customers that your website is safe.

If someone claims to be from your bank, you should be able to reach that person by calling your bank’s publicly listed phone number and being routed by an operator. Malware scanning and intrusion detection tools like ThreatStack are available, as well as tools to monitor for any file modifications or additions. Take care when selecting CMS plugins or server applications to install. Run applications with non-administrative privileges wherever possible.
