Enabling and Disabling the Java Security Manager

A Java security manager prevents code from calling System.exit. When a security manager is enabled, the node process by accidentally or by calling System.exit. However, a security manager may lead to a performance degradation if code is written to perform most system API calls in a privileged block according to Java best practices for security. Therefore, although a security manager is available for a node, by default the security manager is disabled. You can set a node configuration property to enable the security manager in scenarios where the safety measure is more important than the performance or for diagnostic purposes.
