Cloud Monitoring And Forensic Using Security Metrics

  1. 1. CLOUD MONITORING AND FORENSIC USING SECURITY METRICS Presented By: Sandeep Saxena Co-Author: Goutam Sanyal Galgotias college of Engineering & Technology, Greater Noida, India
  3. 3. IntroductionCloud computing is a new emerging technology in the era of science. This immediately brings up several important questions like- Why we use cloud computing? Is it real, or just another catchphrase? How does it affect us?Cloud Computing : Cloud paradigm is used to enable expedient, on-demand network (cloud) access to a public pool of configurable computing resources ( e.g. networks, services, storage, application and services) that can be fast stipulated and released with minimal management effort or service provider interaction.
  4. 4. 2 types of cloud:1. Public Cloud2. Private cloud Figure 1 : Public cloud ( Service Provider) and Private Cloud ( On- Premises)
  5. 5. Analysis of Previous ResearchValidation security design is based on model and methodology approaches. For example NIST Security made presents telecommunication architecture as combination of 3 layers:a. Infrastructure level: The set of hardware and software components that provide telecommunication functionality.b. Service level: Billed customer traffic flows.c. Application level: It motivates users to pay for the control layer services.
  6. 6.  Security Issues : Confidentiality , Integrity , Availability For such issues , we need to monitor the user’s activity as prevention measure to provide security to other users on network. Monitoring and Forensic is major concern of security for taking appropriate action against intruder or attackers. Architectural services of cloud computing:a) Software-as-a-Service (SaaS):, GoogleApps etc.b) Platform-as-a-Service(PaaS):Google Apps Enginec) Infrastructure-as-a-service(IaaS): Amazon web services
  7. 7.  According to Jennifer Bayuk : Iaas service provides secure network and storage services and Saas provides secure application service. According to D.Zissis and D.Lekkas : Trusted third part implemented to provide strong authentication for financial transaction, authorization, data confidentiality and non repudiation. According to Gary C. Kessler: Find root cause of forensics. According to M. Tayor: Forensic experts install packet sniffers and monitoring tools on targeted machine to collect information. In private cloud it would be easy but in a public cloud it will be more difficult.
  8. 8. Proposed Methodology Monitor Consumer Activity and Save Session log Records Find any Malicious activity Match with Signature Automated Forensic System will be activated to Store All Activities and Data in Metrics Stop Remote Access OR outside the cloud services ( at the same time massage send to consumer on phone and Email ) Administrator check security metrics and collect Data then send to higher authority for legal ProcessingFigure 2 : Monitoring and Forensic Methodology
  9. 9. Proposed Generic Model for Cloud Computing and Forensics Here we proposed an complete architecture to provide service to our consumer included secure monitoring and forensic system. Service level agreement ( SLA ) : Signed by Consumer. In our architecture , we used Host- based IDS for monitoring of incoming and outgoing network communication on consumer system. IDS includes both anomaly detection and misuse detection techniques for identifying activities on host system. It includes 6 steps which are shows in figure 2.

  11. 11. Conclusion and Future work We proposed a forensic methodology to assure the confidentiality of user of cloud. Create security matrix and audit trail for investigation. Establish service level agreement (SLA) with customer. In future, focus on rule base security matrix and integrity of user’s data.
