How to Keep Your Java Applications Secure - DZone Security

How to Keep Your Java Applications Secure - DZone Security

The solution to keeping your Java applications secure is simple: make sure they stay up to date. Check out the details within.

A little over a year ago, in April 2019, the way most Java users accessed updates for the JDK changed. The reason for this was a combination of changes made by Oracle to how the JDK is developed and the licensing terms of the Oracle JDK.

The Oracle JDK 11 and Oracle JDK 8 (from update 211) now use the Oracle Technology Network License Agreement. This limits free use to only four cases:

  1. Personal use (laptop or desktop for personal applications)
  2. Development use
  3. Oracle approved product use
  4. Oracle cloud infrastructure use

For all other cases, a Java SE subscription must be purchased from Oracle.

This has required users to make decisions about their JDK deployment strategy. One such approach is "Well, it works fine on the JDK we have now; let's just stick with that."

There is an obvious flaw to this, which is the effect this decision will have on the security of applications.

Ever since people started developing software, other people have been trying to find ways to use it in ways not originally intended. This is often for malicious goals such as stealing credit card numbers or user's identities. We use the term to describe someone who is able to subvert computer security. There are a myriad of ways that hackers use to achieve their goals; from fooling people into revealing confidential information (phishing) to sophisticated manipulation of software through techniques like buffer overruns.
