1. SECURITY AS A SERVICE: CHALLENGES AND UNDERSTANDING TELECOM PARIS TECH- FRANCE FOUAD GUENANE 26/02/2015

2. AGENDA  Context  Security As A Service  Hybrid Deployment Architecture  Cloud Based Deployment Architecture  Futur works  Conclusion

3. Context  In 2013, 60% of companies were DDoS-attacked, up from 35% experiencing a disruptive attack in 2012 (Neustar Annual Report 2014)  87% of companies attacked were hit multiple times  In 2013, 74% of companies reported that DDoS attacks lasted less than a day (16% between 1-2 days).  Attacks between 1-5 Gbps represent approximately 20% (One amplification attack this year measured 400 Gbps)

4. Context  DDoS drains manpower: over half of businesses (57%) need 6 or more people to mitigate DDoS attacks  For small and medium businesses (up to 5 Mbps of Internet connectivity):  Deployment and maintenance are estimated to $116,075 for the first year  An annual cost of $108,200  Hence, there is a growing interest in outsourcing security services to a Cloud provider in order to reduce firewall management and deployment costs

5. Security As A Service  Security-as-a-service (SaaS) is an outsourcing model for security management.  Typically, Security as a Service involves applications such as anti-virus software delivered over the Internet  But the term can also refer to security management provided in-house by an external organization. (Cloud Security Alliance)

6. Security As A Service  First line of defense  Expensive costs which include:  Human resources and training  Maintenance, updates and the price of licenses  Deployment costs  Limited resources  High availability  Ability to add or remove firewalls dynamically  Increase in processing capacity (Throughput)  Centralized or distributed management  Provisioning of resources (needs) Physical FirewallVirtual Firewall

7. Hybrid Deployment Architecture

8. We explore two mechanisms:  Secure Forwarding Architecture  Secure Sharing Architecture

11. Cloud Based Deployment Architecture

12. The general model proposed looks like a huge proxy or proxy server and consists of three main components: Front Gateway Instances de Firewall Back Gateway

13. Cloud Based Deployment Architecture

14. Futur Projects  Security and Privacy in Cloud governance  Inter-Cloud (interconnection of Cloud Provider)  RFID Technologies for Tracability  Green Computing  …etc.

15. Conclusion  Innovative architecture to effectively manage the performance and reliability in a cloud-based firewall  Encouraging and promising preliminary results  network administrators could manage their infrastructure with the expertise of their Cloud provider for better exploitation
