By impersonating legitimate users, intruders can use the abundant resources of cloud computing environments. This paper develops a framework for "CIDS" a cloud based intrusion detection system, to solve the deficiencies of current IDSs. CIDS also provides a component to summarize the alerts and inform the cloud administrator. CIDS architecture is scalable(More)
Cloud computing is an attractive model that provides the delivery of on-demand computing resources over the Internet and on a pay-for-use basis. However, while intruders may exploit clouds for their advantage, most IDS solutions are not suitable for cloud environments. This paper presents a hierarchical and autonomous cloud based intrusion detection system,(More)
A masquerade attacker impersonates a legal user to utilize the user services and privileges. The semi-global alignment algorithm (SGA) is one of the most effective and efficient techniques to detect these attacks but it has not reached yet the accuracy and performance required by large scale, multiuser systems. To improve both the effectiveness and the(More)
Security and availability are critical for cloud environments because their massive amount of resources simplifies several attacks to cloud services. This paper introduces a distributed deployment and a centralized one for our Cloud intrusion detection framework, CIDS-VERT. After describing the architectures and the components of the two deployments it(More)
Masquerade attacks pose a serious threat for cloud system due to the massive amount of resource of these systems. Lack of datasets for cloud computing hinders the building of efficient intrusion detection of these attacks. Current dataset cannot be used due to the heterogeneity of user requirements, the distinct operating systems installed in the VMs, and(More)
Cloud computing is a type of distributed computing approach for IT Sector that leverages in efficient pooling of on-demand, self-managed virtual Infrastructures consuming them as a service by applications/organizations which would save thousands of dollars on CapEx and OpEx. To adopt this new cloud technology main concern for the consumers is the cloud(More)
Security problems arise in software systems are very challenging. Using program analysis techniques and some language based security rules can help in enforcing application-level security through control access to program resources and verification of control flow of the information inside the program based on some security properties. This paper presents a(More)
The extensive use of virtualization in implementing cloud infrastructure brings unrivaled security concerns for cloud tenants or customers and introduces an additional layer that itself must be completely configured and secured. Intruders can exploit the large amount of cloud resources for their attacks. Most of the current security technologies do not(More)
