Harmon at the 2013 Annual Meeting introduces the fundamentals of virtualization and cloud computing, emphasizing both their transformative potential and the security considerations they entail.</p> <h2 id="cloud-technology">Cloud Technology</h2> <p>First, Harmon unpacks virtualization basics like defining hypervisors (Type 1 and Type 2), guests, and core virtualization architecturesand maps these concepts onto cloud service models such as Software-as-a-Service (SaaS), Infrastructure-as-a-Service (IaaS), and Anything-as-a-Service. He highlights key benefits including server consolidation, rapid provisioning and decommissioning of resources, auto-patching and silent upgrades, reduced operational overhead, and the ability to harvest processing power on demand. This framing positions cloud computing as a natural extension of traditional virtualization that delivers scale, flexibility, and cost efficiency.</p> <h2 id="security-and-privacy-risks">Security and Privacy Risks</h2> <p>Second, the presentation shifts to the security and privacy risks inherent in cloud environments. Harmon details confidentiality challenges in multi-tenant platformswhere co-located data often lacks provider-managed encryption and availability threats stemming from service outages, contractual lock-in, or disputes with providers. He also addresses integrity risks due to limited transparency into vendor operations and the potential for insider threats. To mitigate these issues, he advocates a trust but verify approach: enforce end-to-end encryption (in transit, processing, and at rest), conduct rigorous vendor audits, codify security requirements in contracts, and maintain continuous risk assessments to ensure that cloud-hosted assets remain under organizational control and resilient against data breaches.</p> <h2 id="presentation">Presentation</h2> <p><a href="/attachments/56461_2013-06-18_CloudSecurity-ISC2TC.pdf">Cloud Security</a></p>
