SEC524: Cloud Security Fundamentals

Many organizations today are feeling pressure to reduce IT costs and optimize IT operations. Cloud computing is rapidly emerging as a viable means to create dynamic, rapidly provisioned resources for operating platforms, applications, development environments, storage and backup capabilities, and many more IT functions. A staggering number of security considerations exist that information security professionals need to consider when evaluating the risks of cloud computing.

The first fundamental issue is the loss of hands-on control of system, application, and data security. Many of the existing best practice security controls that infosec professionals have come to rely on are not available in cloud environments, stripped down in many ways, or not able to be controlled by security teams. Security professionals must become heavily involved in the development of contract language and Service Level Agreements (SLAs) when doing business with Cloud Service Providers (CSPs). Compliance and auditing concerns are compounded. Control verification and audit reporting within CSP environments may be less in-depth and frequent as audit and security teams require.

The SANS Cloud Security Fundamentals course starts out with a detailed introduction to the various delivery models of cloud computing ranging from Software as a Service (SaaS) to Infrastructure as a Service (IaaS) and everything in between. Each of these delivery models represents an entirely separate set of security conditions to consider, especially when coupled with various cloud types including: public, private, and hybrid. An overview of security issues within each of these models will be covered with in-depth discussions of risks to consider. Attendees will go in-depth on architecture and infrastructure fundamentals for private, public, and hybrid clouds. A wide range of topics will be covered including: patch and configuration management, virtualization security, application security, and change management. Policy, risk assessment, and governance within cloud environments will be covered with recommendations for both internal policies and contract provisions to consider. This path leads to a discussion of compliance and legal concerns. The first day will wrap-up with several fundamental scenarios for students to evaluate.

Attendees will start off the second day with coverage of audits and assessments for cloud environments. The day will include hands-on exercises for students to learn about new models and approaches for performing assessments, as well as evaluating audit and monitoring controls. Next the class will turn to protecting the data itself! New approaches for data encryption, network encryption, key management, and data lifecycle concerns will be covered in-depth. The challenges of identity and access management in cloud environments will be covered. The course will move into disaster recovery and business continuity planning using cloud models and architecture. Intrusion detection and incident response in cloud environments will be covered along with how best to manage these critical security processes and technologies that support them given that most controls are managed by the CSP.

Author Statement

The cloud is everywhere! Well, that's what the marketing folks would have us believe, anyway. For security professionals, migrating systems, applications, and data to the cloud presents a new set of challenges to tackle. What kind of policies do we need, and how can we work with legal teams to incorporate language into contracts? How can we protect sensitive data with encryption, intrusion detection and prevention, and host and network access controls? Can we extend identity and access management tools and processes into the cloud?

Fundamentally, the cloud represents a move into environments where security teams are giving up some measure of control over how data and applications are protected. Due to capital and operational cost savings, cloud-based services are becoming more attractive to business and organization leaders, and security teams will need to understand their options when presenting the risks to management. In Cloud Security Fundamentals, our goal is to arm security teams with the knowledge they need to assess risks in moving to the cloud. Managers, auditors, and systems and network administrators will also benefit, as we'll delve into the technologies available for securing cloud-based assets while covering all the policies, processes, and compliance considerations that go along with this major technology shift, as well.
