Java Runtime Application Self Protection means Java application self-protection system, which is called 'jrasp' for short.

jrasp-agent is the core part of jrasp project.

jrasp-agent based on Java Agent technology, modifies Java bytecode, adds security detection logic, detects and blocks vulnerability attacks in real time.

• Security plug-in can be customized
• Detection logic low delay
• Plug in Hot Update
• Java Process Identification and Automatic Injection
• Support native method hooks such as command execution to completely prevent bypassing;
• Compatible with Windows, Mac and Linux
• Small size, core jar package 600KB

• Increase CPU by 5% (test under normal request)
• Memory consumption below 200MB

• Plug in and daemon HASH verification
• Agent and Daemon socket customized communication protocol and RSA asymmetric encryption;
• The core functions are loaded by custom class loaders and isolated from business classes, which improves the difficulty of attacking RASP from within the JVM;
• Reflection reinforcement: RASP core methods (such as unloading, degradation, etc.) reflect reinforcement to prevent malicious reflection;
• Do not use third-party frameworks, such as servlet, json, sl4j2, apache common, etc

how to install

Due to the high number of installations of this product, based on product safety considerations, no longer open source code, partners can provide jrasp basic framework source code
