Explore cloud computing security in this 53-minute lecture by Dr. James Walden. Delve into the emerging paradigm of cloud computing for large-scale web application deployment, examining its potential to reduce complexity and costs while introducing new risks. Understand why traditional security approaches like firewalls and network intrusion detection may be ineffective in cloud environments. Investigate key risks such as loss of governance, regulatory compliance challenges, expanded attack surfaces, and hypervisor vulnerabilities. Learn about mitigation strategies for these cloud-specific security concerns. Cover topics including cloud service architectures, deployment models, data loss prevention, virtualization security features, inter-VM attacks, and the complexities of maintaining security in scalable, transient cloud environments. Gain insights into public key cryptography, homomorphic encryption, and their applications in securing cloud data.
