2©2012 Check Point Software Technologies Ltd. Security as a Service  Not the topic of this presentation  Many types of security services: –Mail Security (Postini) –Web Security (ZScaler) –DDoS (Prolexic) –Anti-Virus (VirusTotal)  Many security offerings rely on Cloud Services (e.g. signature updates, reputation services etc.)

3©2012 Check Point Software Technologies Ltd.  Cloud can mean many things: –IaaS (AWS EC2, Google Compute Engine) –PaaS (Facebook Apps, AWS BeanStalk) –SaaS (SalesForce, Facebook) –Private / Public / Community clouds –Enterprise / Consumer

4©2012 Check Point Software Technologies Ltd. Public cloud - new Security concerns  Physical security  Data lifecycle  Foreign governments  Multi-tenants: –Hypervisor attacks –Network attacks: –Sniffing –Spoofing –DDoS

5©2012 Check Point Software Technologies Ltd. Security Built-in?  The big cloud providers are taking security into consideration: – center/security/ center/security/ – –  Seems like economies of scale play in favor of both parties: –The cloud provider is likely to have better security knowhow –Improved resiliency under attacks (DDoS & DR)

6©2012 Check Point Software Technologies Ltd. Separation of Responsibilities

7©2012 Check Point Software Technologies Ltd. Separation of Responsibilities  Customers can only manage security at the tiers they are responsible for  Customers must manage security at the tiers they are responsible for  Example: –In a PaaS Enviornment: –The cloud provider is responsible for patching the OS layer –The customer needs to make sure there are no vulnerabilities in his application code

8©2012 Check Point Software Technologies Ltd. S3  A “Simple Storage Service”  Upload and download of data objects  Data in motion: –SSL/TLS  Data at rest: –Client side encryption + key management –Server side encryption  A simple service with little security implications

9©2012 Check Point Software Technologies Ltd. SalesForce  The de-facto standard in CRM (customer relationship management)  Enjoy a big corporates install base  Stores very sensitive corporate data (list of customers, potential deals etc.)  Security concerns: –Authorization and access control –Data Loss Prevention

10©2012 Check Point Software Technologies Ltd. Authentication to cloud Apps  Requirements (enterprise) –Strong authentication –Single sign on –Automatic User de-provisioning –Support office, remote and mobile users –Support multiple SaaS providers  Solutions: –SAML- for corporate –OpenID- mostly for consumer –OAuth - “machine to machine”

12©2012 Check Point Software Technologies Ltd. Data at rest – SalesForce (and others)  Solution: –A proxy + tokenization/encryption service (e.g. CipherCloud) –Difficulty around ‘search’ functionality: –compromise security –Homomorphic encryption? –Fragile and limited

13©2012 Check Point Software Technologies Ltd. Network architecture  Network architectures: –Blurred perimeter: –Limited network topologies –Multiple cloud providers - similar but different –Limited or no control over tiers managed by the cloud provider –SDN  Overlay of security management: – –Cross vendor / region –Dynamically close/open ACLs –Dynamically close/open host FWs
