The java.security File

The java.security file contains configuration data used to initialize the security framework, and security properties for keeping the JDK environment secure. The file itself has extensive information about how to use it.

Its location depends on your operating system:

Linux / Solaris / macOS:

• JDK 11 and later: [JDK_HOME]/jdk-11.[VERSION]/conf/security/java.security
• JDK 7 and 8: [JDK_HOME]/jre/lib/security/java.security

Windows:

• JDK 11 and later: [JDK_HOME]\jdk-11.[VERSION]\conf\security\java.security
• JDK 8: C:\Program Files\Java\jdk1.8.0_[VERSION]\jre\lib\security\java.security
