Cloud Security on Ulitzer
Safeguarding a cloud infrastructure from unmonitored access, malware and intruder attacks grows more challenging for service providers as their operations evolve. And as a cloud infrastructure grows, so too does the presence of unsecured privileged identities – those so-called super-user accounts that hold elevated permission to access sensitive data, run programs, and change configuration settings on virtually every IT component. Privileged identities exist on all physical and virtual operating systems, on network devices such as routers, switches, and firewalls, and in programs and services including databases, line-of-business applications, Web services, middleware, VM hypervisors and more.
Left unsecured, privileged accounts leave an organization vulnerable to IT staff members who have unmonitored access to sensitive customer data and can change configuration settings on critical components of your infrastructure through anonymous, unaudited access. Unsecured privileged accounts can also lead to financial loss from failed regulatory audits such as PCI-DSS, HIPAA, SOX and other standards that require privileged identity controls.
One of the largest challenges for consumers of cloud services is attaining transparency into how a public cloud provider is securing its infrastructure. For example, how are identities being managed and secured? Many cloud providers won’t give their customers much more of an answer than a SAS 70 certification. How can we trust in the cloud if the vendors of cloud-based infrastructures neglect to implement both the process and technology to assure that segregation of duties are enforced, and customer and vendor identities are secured?
The Cloud Vendor’s Challenge: Accountability
Cloud computing has the potential to transform business technology, but it brings security issues that IT organizations should consider before trusting their sensitive data to the cloud. These issues should cause security experts and auditors to rethink many fundamental assumptions about Privileged Identity Management in terms of who is responsible for managing these powerful privileged accounts, how they manage them, and who exactly is in control.
Historically, IT data centers have always been in secured physical locations. Now, with cloud computing, those locations are no longer maintained directly by the IT organization. So the questions are these: how do you get accountability for management of physical assets that are no longer under your physical control, and exactly what control mechanisms are in place? Can you trust your cloud vendor to secure your most sensitive data? Moreover, if there’s a security breach in the cloud, who is to blame? Is it the cloud vendor that disclaims all legal liability in its contract, or an enterprise that relinquishes control of its sensitive data in the first place?
Cloud computing promises to make IT more efficient and deliver more consistent service levels. However, there’s a paradox that when it comes to security (and control over privileged identities in particular) cloud services are often among the least efficient. Many cloud service providers’ processes – based on ad-hoc techniques like scripting of password changes – are slow, expensive and unreliable. And that’s dangerous.
Fortunately the industry is starting to move beyond paralyzing discussions about the security and compliance problems that arise from cloud computing to address them head on. One example is the Trusted Cloud Initiative, which was launched at RSA Security Conference 2010. The goal of the initiative is “to help cloud providers develop industry-recommended, secure and interoperable identity, access and compliance management configurations, and practices.” However, only time will tell if it will help standardize cloud computing or turn out to be a technology certification of little use.
Several major cloud vendors and ISPs have begun the task of integrating security solutions that are capable of managing the large number of privileged identities that make up their infrastructure (hardware, VM hosts, VM Image OS, application stacks). This has really broken the fundamental model of IT being in control of security and has started to blur the lines between vendor and customer when it comes to the management of security.
Today, some privileged identity management frameworks are capable of managing “from iron to application,” giving cloud customers a full measure of control over credentials used in each physical and virtual layer of the stack and the potential to gain full visibility into who has access. In contrast, scripts and other ad-hoc methods to manage privileged identities can no longer keep pace or meet regulatory requirements in fast-changing and highly virtualized cloud computing environments.
In addition, cloud vendors must move to become identity providers of authentication services, multi-tenancy control, and X.509 certificate issuance for applications, end-points, users, and encrypted sessions. It is inappropriate for cloud vendors to expect their customers to use disconnected and third party providers of certificate services for what should be an inherent and integrated feature of every cloud vendor’s offering.
The End User’s Challenge: Transparency
In my opinion, the cloud is a really good, compelling idea. It can reduce the cost of IT dramatically. Given that cloud computing is available, the idea of building new data centers these days seems like a last-century way of doing things. And since many organizations lack the appropriate personnel to manage the IT resources they have, they’re willing to forego seeing and touching their own systems in their secured data centers – and the corresponding feeling of control – and have turned to outsourcing. Cloud computing is essentially the next generation of outsourcing, so we’re not only reducing manpower but also getting rid of our hard assets entirely. By moving these services to data centers anywhere on the planet we’re offered the potential for service delivery that costs far less than the alternatives. And the idea of outsourcing security and liability is extraordinarily compelling.
However, enterprises should ask the right questions of their cloud providers before taking the leap into the cloud and blindly assuming that their data is safe there. You should ask your cloud service provider to meet every point of compliance that your IT organization is required to meet, and should ask your cloud service provider every question that your IT auditors ask you.
Auditors, too, share a responsibility to verify that client organizations are able to track the usage and control of their data and resources inside the cloud. In keeping with major regulatory mandates, auditors are obligated to confirm segregation of duties and the enforcement of “need to know” and “need to access” policies. And, potential cloud customers should ask what provisions have been made to provide the required trail of access to the user’s auditors on demand – and what provisions are in place to allow the sharing of privileged control between cloud vendor and user for appropriate reporting and verification.
Because today’s cloud vendors offer literally no transparency and little information, don’t be surprised if you don’t like the answers you get. Most cloud vendors would say that for security purposes, it’s on a “need to know” basis and you don’t need to know. Others state that they’re SAS 70 compliant, but that’s really just a self-certification. And because each measure of security adds to cloud vendor costs, it is appropriate for consumers of cloud services to demand to know precisely what measures are in place – and what auditing processes are supported – as part of the service agreement.
Be persistent. What kind of security does the cloud service provider have in place to protect your privileged accounts and most sensitive data? Do they have Privileged Identity Management technology in place? How do they control privileged accounts used in cloud infrastructure to manage sensitive systems and data? How do they manage cloud stacks at the physical layer and application stack layers ? What is your access to audit records?
Whatever regulatory standards your organization must meet, so too must your cloud vendor. So if you think that by venturing into the cloud you’re saving yourself from regulatory headaches, think again.
Security is the greatest barrier towards adoption of the cloud, and it’s no great surprise that cloud security was a major theme at this year’s RSA Conference. Unfortunately, improvements in cloud security won’t be seen as a priority until a major breach has a significant impact on one or more cloud service vendors and their customers. This needs to change. When it comes to cloud security, it is the end-user’s duty to understand what processes and methodologies the cloud vendor is using to protect the customer’s most sensitive assets.

Very good article and very comprehensive view of the assurance issues surrounding identity management in the cloud. One clarification (and I could see what you were getting at so its not as if you misconstrued) but I wanted to clarify that SAS 70 is not a self-certification.
First, SAS 70 is not a certification at all although I agree with you that technology marketers love to issue press releases saying that it is. Second, you are correct in that there are no prescriptive standards and that what is being tested are the control activities and objectives set by the provider.
That said, the two do have to interrelate for a CPA to render an unqualified opinion. For instance, if the (high-level) control objective provides reasonable assurance against unauthorized access and the (detailed) control activities tested by the auditor were only paper-based (policies) with no technical preventive or detective controls, the result would likely be a qualified or adverse opinion on that objective if not the broader controls.
The bottom line is while yes, the cloud provider dictates what the objectives and activities are, you won't get an unqualified (some refer to as clean) opinion if the controls are not suitably designed and/or fairly presented.
