It addresses both the system level issues such as mobility, global naming and security, and the language-level support for agent programming including models and primitives. The Ajanta architecture includes a generic agent server which provides a secure agent execution environment. Agents are isolated within protection domains, created using features of the Java environment. In Ajanta, mobile agent transfer is encrypted and authenticated using the EIGamal and DSA protocols, the resource access are based on capability, and authorization is based on agent's Security Issues in a Mobile Agent System 47 owner.
It is widely used to protect secure-sensitive contents such as passwords, files, mutual communication, etc. When two entities need to talk or exchange some information, the initiator should encrypt the readable plain text into illegible cipher text. Then the cipher text is transmitted over the communication channel, which is most probably unsecured. When the Attacks and Countermeasures of Software System Security 29 receiver gets the cipher text, it decrypts it into readable plain text again. Figure 3 illustrates the cryptography process.
For example, the Next-generation Intrusion Detection Expert System (NIDES) developed by SRI contains a statistical dynamic anomaly detector . Anomaly detection can identify new and previously unseen attacks. But it is difficult to determine the boundary between acceptable and anomalous behavior at some time, so it will have higher false negative and false positive rates. And an experienced intruder could train an anomaly intrusion detection system gradually to accept an intrusion as normal behavior.
