Network telemetry data is considered a gold mine for researchers for performing traffic analysis, QoS, security forensics, malware spread etc. Cloud Consumers could benefit from variety of Cloud based security services if such telemetry data is made available. But there is a compelling need for ensuring privacy of sensitive fields before data is shared with any Cloud provider. In this paper we provide...
Consider a cloud deployment where the organizational network pertaining to a tenant having routers, switches sharing network telemetry data on regular basis. Among different ways of managing networks flow-based network monitoring is most sought after approach because of accuracy and economies of scale. In the event of host compromise the device credentials are revoked thereby disabling its ability...
We consider the scenario where a consumer can securely outsource their network telemetry data to a Cloud Service Provider and enable a third party to audit such telemetry for any security forensics. Especially we consider the use case of privacy preserving search in network log audits. In this paper we experiment with advances in Identity Based Encryption and Attribute-Based encryption schemes for...
Cloud computing works on various service models like SaaS, PaaS, IaaS. The enterprises outsource data and computation to cloud and benefit from cloud computing unique attributes like abundant storage, network and compute. This paradigm also brings forth many challenges for data security and access control. Many organizations are choosing Cloud platforms for software development/testing, particularly...
