10 Important things to check regularly for application security


Application security is more important than ever. Over the years, IT has evolved at a record pace while the potential consequences have increased even more rapidly. For many, application security is critical that you keep up the pace and secure your apps or you may face potential disasters because of compromises — from leaking your data and huge monetary losses to your organisation’s name being ruined overnight. The most worrisome part is that cybercriminals become increasingly inclined to leverage any security vulnerability they discover. As a result, your data breach enforcement, intellectual property theft, and customer trust can all be compromised.

1. Don’t let outdated software put your app at risk

Arguably the most basic measure to ensure application security is updating the software you use. This is because software producers release new updates to fix security weaknesses, bugs, and improve performance. If one does not update the software, some of the weaknesses may be easily targeted leading to a security breach. It is advisable to always check for new updates for the various software components such as the operating system, web servers, databases, libraries, and web applications. In addition, one can also configure automatic software updates or check manually frequently.

2. Scan for vulnerabilities, prevent security calamities

The newest software update may have you covered for new vulnerabilities, but even new ones may emerge at any minute. As a result, you must continuously conduct a vulnerability scan of your applications and infrastructure. With the recruiting between out-of-date components, misconfiguration, and coding flaws, it’s merely a matter of time before a cybercriminal takes advantage of a security vulnerability. Using Your Vulnerability Scanning Tools or Services Scan your applications consistently with dependable vulnerability scanning tools and services to unearth known vulnerabilities.Surveil the issue identified and eliminated.

3.  Access controls: The gatekeepers of your app’s security

Access controls play a significant role in restricting who accesses your application and the activities they engage with while using the application. Strong access controls reduce the potential for malicious access to the application while only allowing identified users with the necessary privileges to use it. Regularly review and moderate user access permissions while observing the principle of least privilege. Disable or delete redundant accounts and set up strong password policies. MFA may also be implemented, particularly for special user accounts.

4. Your app’s security breadcrumbs

Logs are invaluable sources of information that can help you perceive your application’s security state. Logs are usually used to record events, activities, and, as a result, possible security breaches that you can manage promptly. Keep regular monitoring and analysis of your application’s logs. Pay attention to some kind of unusualness, e.g., abnormal login requests, sign-up activities, and irrelevant usages — all outside the rules. Also, use log management solutions to centralise logs to corral data for easy analysis and correlation.

5.  Data security: Safeguarding your app’s precious cargo

Data is a universal building block of practically all applications, and data security is by far and away essential to the integrity of any IT solution. The diversity of applications does not matter: you may work with sensitive user data, financial details, proprietary information, or all of the above. Therefore, data encryption underlies industry-standard encryption algorithms and key management solutions at a minimum to provide you with visibility, control, and constraints over who may access your data and what they are doing with it. Preferably you should pick a solution that allows you to set your data retention and deletion specifications, which you must periodically verify to make sure it is consistent with the protocol and even better, the best practices.

6. Input validation and output encoding: Guarding against malicious attacks

In cases where you do not carry out enough input validation and output encoding, your application will almost certainly be prone to SQL injection and cross-site scripting, as well as other code injection dangers. As a result, you must verify the input while you clean the input and verify user input prior to processing . The output should also be encoded to prevent unauthorised code insertion into the application responses.

7. Secure communication: The key to keeping your data safe in transit

Today’s world is interconnected, and data is almost being teleported from one system to another, or from a device to a system. All communication channels should be secured, or there might be eavesdropping, tampering, or a man in the middle. In Chrome Healthcare, websites use secure protocols for web-based ones, such as HTTPS/TLS, and an encrypted VPN connection is utilised for internal communication.

8. Security awareness training: Empowering your team to defend against threats

No matter how critical technical security countermeasures are, the human factor frequently stands as the weakest area of application security. Training your staff in security basics and sharing knowledge of possible threats is an important part of security hygiene. Regular security training events for all employees should include topics like awareness of phishing, password practices, types of social engineering, and responses for possible attacks reporting.

9. Secure development: Building security into your app from the ground up

Integrate security throughout the SDLC: secure development from scratch is the best practice, so it is extremely important to integrate security throughout software development. The process helps identify vulnerabilities early in the procedure and removes the enemy areas. Security coding is also required, including input validation, output encoding, and secure authentication and authorization. Conduct the code testing, therefore, it is possible and static code analysis, to define and remove any defects.

10. Security policies: Your app’s roadmap to a secure future

Security is a rapidly growing field, and your security policies should keep up with the most current hazards, greatest methods, and legislative mandates. To ensure that your security policies are effective and appropriate, you must review and update them regularly. Implement a procedure for periodic policy updates that is suitable for each stakeholder, including security, IT, and legal and compliance teams. Impose disciplinary action on all aspects of how your policies are documented, communicated, and applied throughout your company.


Application security is not a final state; it is a constant commitment that has no end. Regularly monitoring the ten aspects mentioned in this article, updating, and fixing them will make your mobile application security more secure and protect your organisational assets from potential cyber threats. Be aware that security is everyone’s responsibility and educate your teams, from developers to executives, on safe security practices. Finally, always stay up-to-date and refreshed on the most recent security trends and subjects and alter your security strategy.
