Tips to prevent application vulnerabilities

App or application vulnerabilities are one of the most common targets for malicious activities. This poses a huge threat to both businesses and citizens, potentially resulting in leaks of sensitive information, financial losses, and other consequences. Therefore, whether you are developing an app or simply using it, you should always take the necessary precautions to prevent all possible application vulnerabilities. This article will guide you through some of the most common ways to do this.

Detecting vulnerabilities: the first step to security

Before we can dive into the prevention of app vulnerabilities, it is crucial to understand how to detect vulnerabilities in applications.

Security audits play an important role for businesses in this phase, serving as the first line of defence in identifying weaknesses within applications before they can be exploited by malicious actors. For app users, there are also ways to perform mobile security tests, although using malware detection software is a common choice.

Vulnerabilities can range in severity, and their early detection will be key in avoiding any major harm before it’s too late. Keep in mind that, while automated detection tools can be helpful, they don’t necessarily replace a manual check done by an expert, especially in the more complex security issues. Therefore, performing regular audits is always recommended, particularly for businesses with sensitive user and financial data concerns.

Best practices for app vulnerability prevention in businesses

While detecting vulnerabilities is a critical step, prevention is the ultimate goal. There are several tips on how you can significantly reduce your risk of application vulnerabilities:

  • Secure coding practices: Implementing secure coding guidelines (such as input validation, error handling, etc.) for your developers is fundamental. There are lots of resources available online, which can act as a roadmap to minimise vulnerabilities in coding.
  • Comprehensive security of application components: It is essential not just to focus on the application but also on its underlying components, including the infrastructure (servers, databases, etc.) and third-party libraries, to guard against supply chain attacks.
  • Continuous update and review process: Applications are dynamic, with new updates potentially introducing vulnerabilities. Integrating security reviews into the software development lifecycle can help catch these vulnerabilities early.

Application vulnerability prevention tips for users

Individuals can also take measures to safeguard their personal information from application vulnerabilities. Here are the best practices for users:

  • Regularly update applications: Ensure that all your applications are updated to the latest version. Developers often release updates to patch security vulnerabilities, so these should not be ignored.
  • Use strong, unique passwords: As tempting as it is to have your birthday as a password, you will be much safer creating more unique passwords. Ideally these will be different for different applications too.
  • Use two-factor authentication: If possible, use two-factor authentication on your accounts (e.g. you must type a one-time SMS or email passcode to access the app). This adds an extra layer of security beyond just the initial password.
  • Be wary of suspicious links and downloads: Always avoid clicking on suspicious links or downloading attachments from unknown sources, as these can introduce malware into your devices. Educate yourself on the various scamming and phishing methods, so you can recognise them easily while browsing the internet.
  • Monitor account activity: Regularly check your account activity for any unauthorised actions, or have a notification on for when an unusual login attempt is made. The majority of applications provide logs of recent activities, which can help you spot something suspicious.
  • Secure your devices: Keep your devices secure with antivirus software and ensure that your operating system is up-to-date. A properly secured device is less vulnerable to attacks that could exploit application vulnerabilities.

Managing detected vulnerabilities

If a potential vulnerability has been detected in your app, dealing with it swiftly will be the next important step. Here’s what the process includes:

  • Assessing the vulnerabilities: First and foremost, you need to understand the severity of the detected vulnerabilities and know which one to prioritise if multiple have been found. There are various tools and indicators you can use for this, helping you figure out how likely the vulnerability is to be exploited by hackers.
  • Developing a remediation plan: Once you know what to prioritise, create a plan on how you will approach it. Try and be strategic about it, addressing the most important areas first, considering the potential business impact.
  • Fixing the issues: Using your plan as a guide, fix the vulnerabilities using the most suitable methods. If you are not completely sure how to deal with them, get in touch with a security expert to help you.
  • Continuous monitoring and assessment: After the vulnerability has been fixed, test and audit the application again to ensure that everything is working as expected. Regularly re-evaluate the application’s security to adapt to new threats and vulnerabilities as they emerge.


Effective detection and prevention of application vulnerabilities are vital to maintaining the security and integrity of digital platforms. With these measures in place, you should be able to safeguard your apps from malicious activity.
