These Are The Ways For Developing Highly Secure Java Applications



One of the most widely used and oldest development platforms Java has a lot of built-in security features. Furthermore, its security package is meticulously tested and periodically upgraded. The dangers associated with cloud and micro-services architectures are sought with each and every new update. Often, business owners want to have the best security practices of a Java development company before deciding to hire it for Java development services.

Security is one of the broadest, most critical and complex aspects of software development. More often, security is also overlooked or even simplified to just  little minor adjustments at the end of the development cycle. The annual list of major security breaches strengthened this. Last year, security breaches amounted to more than 3 billion exposed records with Capital One.

The great thing, however,  is that Java has a newer security API, and the ecosystem includes a huge range of tools to profile and report security concerns.

Nonetheless, even with a robust platform, it’s important to remain vigilant. App development is a complex task and vulnerabilities could hide in the background noise. It’s always wiser to follow the best practices when it comes to development.


  1. Keep codes clean and robust: Cluttered and complex coding is a breeding ground for vulnerabilities in terms of security. It is thus wiser and safer to always keep codes simple and clean, minus compromising on quality. Adoption of practices such as avoiding redundancy makes for cleaner and more secure codes. Disperse as little information as possible in the codes.                                                                        Hiding the implementation details means to protect codes from a ranges of vulnerabilities. Leverage the access modifiers of Java by learning to define various access levels for elements such as methods and classes. Define the smallest API possible as well as enable components to interact across the smallest places to ensure that even if one area is breached, others would remain safe.
  1. Avoid coding serialization: An easy yet extremely effective way to ensure Java security. Serialization codes create a remote input and convert code to a completely endowed object. Serialization enables the flow of incognito data to become codes in the JVM or the Java Virtual Machine. Serialization constitutes profound threats to security in programming. Oracle and other software giants already are planning to entirely remove serialization.
  2. Use only genuine and tested Java libraries: Various kinds of support libraries should be used when writing Java apps codes. Although it’s tempting to use the most easily accessible library, it comes with huge risks. Use Java libraries that are tried-and-tested, reliable and with a good reputation all the time.
  3. Never expose unencrypted credentials: Encrypt passwords with a one-way cipher before you incorporate it into the database. Repeat the step when needing to compare it against that value. This measure should be practiced when dealing with information that’s personally identifiable, including bank account details, credit card details, social security number and more.
  4. Always be updated with security releases: A software developer is supposed to be abreast with every security update. Updates should be applied to the Java runtime environment and Java development kit right away. Remain alert on what update is released by Oracle for Java.
  5. Avoid revealing implementation through error messages: A common source of crucial data for hackers is the error messages. Messages such as stack traces could divulge vital information such as the kind of technology used and the development process. Never reveal to end-users the stack races. Other error messages, such as a failed login alert come under this security risk category as well. In case of a failed login, provide minimal information.
  6. Monitor user activity closely: Keeping tabs of the activity of an app is critical to avoid simple and sophisticated attacks. Using the activity monitoring and logging tools could protect the app from various attacks. The tools keep a close tab on app activities and send alerts to the administration in the event of any abnormal activity. An assembly of enterprise-grade and open-source monitoring solutions are available for developing Java solutions.
  7. Be on the lookout for DoS or Denial of Service attacks: Protect the app from runaway resource use each time you process possibly costly resources. Oracle provides a list of potential threats that are related to DoS attacks. When executing operations such as the unzipping of a compressed file, observe the exploding resource use with caution. To ensure security, only trust on-disk or in-memory consumption. Furthermore, look for unexpected forever loops as well. If there’s a suspected loop found, add a guard to ensure loop progress. Finally, it’s important to stay updated on new DoS attacks incidents all over the world.
  8. Track vulnerabilities in dependency: It’s also critical to search for dependency risks when it comes to securing Java web development. The codebase should be scanned for such vulnerabilities. The good news, however, is that a lot of tools could automatically scan dependency and codebase vulnerabilities.

There are so many cyber threats these days and could get worse in the near future. Already, many countries have programs for monitoring and collecting data on cyber sabotage. Governments that don’t have such active programs more or less are likely to implement them in the future. The software industry has long since capitalized on the vastness of Java development. The Java framework covers an entire software development spectrum, which range from mobile applications to enterprise solutions development.

Today’s reality is that you cannot secure each and every code line. Thus, it’s important to always stay on guard and try to avoid vulnerabilities as much as possible. The solution would be to examine the work of the team on a regular basis to make certain that they adhere to the best practices.

Moreover, help developers understand why specific security processes are important. Invest in security management solutions to alert the team in real-time in case something goes amiss. Securing Java apps is something you must do each and every single day to make it right. There is no magic formula to it, it required putting a lot of work.
