2 Cloud transformation happens in phases and will take 5+ years Steps into the cloud Now Network cloud Operator IT OSS/ BSS enterprise cloud Radio Network Cloud OSS/ BSS IT & enterprise Carrier grade clouds typically in silos following operator units Distributing and connecting across the datacenter architecture Logically integrated cloud infrastructure, cloud-scaled and optimized network services Telco Cloud Secure, Five 9 s, low latency, colossal data 2 Source: IDC, Nokia analysis

3 Cloud security is different Nightmare or next hope? John Chambers former CIO of Cisco "You'll have no idea what's in the data center. That is exciting to me as a network player But it is a security nightmare and it can't be handled in traditional ways." Vivek Kundra, Executive Vice President, Industries, Salesforce.com, Cloud computing is far more secure than traditional computing, because (cloud) companies can attract and retain cyber-security personnel of a higher quality than many governmental agencies. 3

4 Top 3 Security Risks in Cloud Environments Virtualization Weakness Dynamicity and Site motion Trust Gap How to preserve Isolation? How to cope with constant and automated changes? How to guarantee Trust and integrity? 4

5 The threats are real Hypervisors are becoming the cloud's security Achilles heel 5

6 Analysts predict it will get much worse... The vulnerabilities are there. It will happen, it s just a matter of time hackers are quite aware that a successful attack at hypervisor layer represents an opportunity to penetrate the entire machine regardless of the security controls within each host. Labs Report 2015 Beyond application sandboxing, McAfee Labs predicts that 2015 will bring malware that can successfully exploit hypervisor vulnerabilities to break out of some security vendors' standalone sandbox systems. 6

7 Business agility requires a re-thinking of the way how security gets implemented Systems and services are launched and retired faster than security teams can identify, analyze, and track Physical boundaries between trusted and untrusted security domains do not exist anymore Security policies are enforced primarily by manually configuration and executed audits and processes Classical perimeter security systems in front of the cloud: Are missing topology and network information of the cloud Cannot cope with the scaling requirements of the cloud Do not see inter-vm traffic Are usually not integrated in the cloud based orchestration processes 7

8 Data and software integrity protection MME Core Cloud IMS HLR GW BSC Data protection: Cloud provider are seen as being responsible for data protection and privacy Shared data layer / bock storage systems need to consider service specific requirements for data privacy Number of open interfaces for data exchange increase significantly Autonomous VNF/service inter-communication requires a new way to authenticate and authorize data-access Radio Cloud SDN Networks OSS Cloud Software integrity protection: software integrity takes on greater significance. Software integrity comprises the whole lifecycle of virtualized applications, which can be roughly divided into the supply chain, the boot/launch and the runtime phase Software integrity must be maintained across different operating systems, software versions and patch levels 8
