7 Practical Tips to Improve Your Web Application Security

    Web applications are one of the most important parts of an organization, and they need to be secured. Everything from a website to an API is a web application, so it's very necessary for you to secure your websites. The problem with most companies is that they don't consider web applications as critical as their other systems, but they're wrong. They must realize that if they want to protect their company from cyber threats then they should pay attention to all aspects of technology including web apps. This article will discuss some practical tips on how you can improve your web application security nowadays.

    Application Security

    Identify What Information Is Critical to Your Business and Protect It

    The first step to improving web application security is identifying what information is critical to your business and protecting it. Protecting sensitive data includes encrypting it at rest and in transit. This can be done by using encryption, or encoding, algorithms that use an access key (password) or another secret key to unlock the data.

    The next step is choosing an algorithm that uses a strong password so that no one can decrypt your encrypted data without knowing the key. The stronger your encryption algorithm and password are, the harder it will be for hackers to break through them. You should also make sure you have strong passwords for every user account created on your site so that if one person's login credentials do get stolen by hackers, they won't be able to access other accounts as well.

    Use Custom Web Application Development

    Custom web application development is a better option than off-the-shelf software. Off-the-shelf products might not provide all the necessary features, or they may not be flexible enough to adapt to your business needs as it grows over time. A custom web application development approach allows you to use the right tools and technologies that are best suited for your business and ensure that you have an integrated solution that will work well together.

    Customized solutions also allow for more secure, scalable, and cost-effective solutions when compared with off-the-shelf products. They can ensure better security by incorporating security-by-design methodologies into the development process, rather than having it added later on after development is complete (which can sometimes be too late).

    Adopt a Risk-Based Development Process

    Define the problem. Before you start, it's important to define what your goal is. By taking the time to clearly define your goals, you can avoid getting lost in the minutiae of implementing a solution and instead focus on getting right to work on what really matters: solving problems and achieving results.

    Set clear goals with deadlines. Having a clear sense of what needs solving will help inform your development process, but without setting specific deadlines for each goal, it's easy for development cycles to stretch out over months or even years without any real progress being made beyond initial conception. Make sure that everyone involved with implementing security measures has an understanding of how long each step will take (and when they're due). Then set firm dates by which they need to be completed so that everyone knows when they have reached their objectives and can move on from there if necessary.

    Build Firewalls Between Critical and Non-Critical Systems

    It is imperative to keep critical systems separate from non-critical systems. This can be done through the use of firewalls and VLANs to protect critical systems. Although it may seem like a good idea to have all of your system resources on a single network, this will only increase your risk of compromise by one system being breached leading to the compromise of many other systems. It is wise to create separate networks for each type of data (e.g., intranet vs extranet) so that if someone were able to hack into one network they would not have access to all other networks in the same way that having an HR database on its own server means that it won't be affected when there's an issue with production servers since they're completely separated from each other.

    Don't Trust Anything That Comes From the Outside World

    Don't trust user input. Never assume the user has provided you with valid data, and don't trust what they've typed in. This applies to all types of data, but it's especially important when dealing with financial transactions or other sensitive information like passwords or credit card numbers. You can try to validate the input manually first (e.g., by comparing it against a whitelist), but if there's no way of doing so automatically, don't pass it on to your application without further inspection.

    Don't trust the client. This seems obvious at first glance who wants to rely on devices full of malware? But even if your users' computers aren’t infected yet, there may be other reasons not to blindly trust what comes from their browsers/mobile apps: many users will use an unencrypted network connection when browsing through public Wi-Fi networks; some people might have outdated versions installed which are vulnerable; and there are also phishing attacks where malicious actors try convincing others that they're accessing their bank accounts securely (by showing them fake login pages), thus tricking them into entering their credentials into these fake websites instead of their actual ones. In short, always verify everything twice before using any sort of input received from external sources.

    Don't trust the network. Networking technologies are constantly evolving at a very fast pace (think about how much things changed over just one decade). Therefore you must assume that any code written today might become obsolete within weeks/months due new discoveries made by hackers who keep finding new ways around our security measures.

    Build Application Firewalls

    You’re probably familiar with the concept of a firewall, which can be used to protect your network from attacks coming in over ports. But did you know that application firewalls can also help protect web applications? In addition to network firewalls, build application firewalls: they can detect and block attacks before they reach your database or web server.

    Application firewalls are software programs that sit between your users and the services behind them (i.e., databases and web servers). They examine all traffic passing through them and look for signs of suspicious activity. If anything looks dodgy, the application firewall will stop it from getting through. This means that an attacker’s attempt at SQL injection or cross-site scripting is stopped before any damage is done, instead of being allowed into your system where it might wreak havoc on its own accord.

    Ensure Website Security by Keeping Your Website and Web Apps Up-to-Date with the Latest Patches

    To ensure website security and prevent hackers from exploiting a flaw in your website, make sure to keep it up-to-date with the latest patches. Patching is the process of fixing software security vulnerabilities. Patches correct problems and prevent future problems by providing new code that fixes the vulnerability. A patch is released by the software developer when they become aware of the vulnerability in their software or are notified by someone else who has found one (the latter happens more often than you might think).

    Once you receive an alert about this new patch or update, you can download it from wherever you purchased your copy of WordPress (for example, or from where you bought other applications such as Adobe Flash Player, Microsoft Windows 10/8/7, etc.


    This article has discussed how to improve your web application security. Emphasized the importance of keeping your website and app up-to-date with the latest patches, keeping critical information secure (and not allowing it to be accessed by unauthorized parties), and working with a third party that has been vetted by trusted organizations. These 7 tips will help you build websites and apps that are more resistant to attacks and better protect sensitive data from external threats.
