Abstract:
Security has been a major challenge faced by the cloud due to its open and
distributed architecture. Intruders can misuse the cloud resources to achieve
their malicious goals. In this thesis, we propose a unique security scheme
Distributed Intrusion Detection System using Mobile Agents in Cloud Com-
puting (DIDMACC) to detect the distributed intrusions in cloud. We have
used mobile agents to carry intrusion alerts from consumer virtual machines
to the management server where correlation takes place. Our system can de-
tect the intrusions on virtual machines, identify the vulnerable ports, and can
correlate malicious events to detect distributed intrusions in a cloud based
network. Mobile agents are also used to update the signature database at
virtual machines being monitored. Mobile agents, being lightweight and
ex-
ible software programs, reduce the network load by carrying intrusion-related
data and code. DIDMACC provides a scalable and robust intrusion detection
system which is a key requirement for cloud networks. We have validated
the security of our system using Ptybull 2.0. The results show that use of
mobile agents and correlation has improved the detection of DoS attacks.
