Abstract
The advancement of computers produce computing infrastructures which handle resources in a more efficient way, and a business model for selling computing resources and services. On the other hand, such complex and distributed architectures becomes an attractive target for intruders. Cloud and distributed computing offers great potential to improve productivity and reduce costs, but at the same time it possesses many new security risks. Some Intrusion Detection Systems (IDS) have been used widely to detect malicious behaviors in network communication and hosts, but these traditional intrusion detection system are not flexible in providing guaranteed security especially in distributed computing because of the architecture of the computing. This paper presents the use of RSA (Rivest–Shamir–Adleman) cryptosystem to effectively detect and prevent intrusion in a computer system. In this cryptosystem, the encryption key is public and it is different from the decryption key which is kept secret (private). This ensures maximum security.
