IT Security Gumbo: Cloud Security Technology

Explore how denial-of-service traffic floods overwhelm networks from many sources using TCP/IP, HTTP, and HTTPS, distinguishing legitimate traffic from attacks, with ports 80 and 443 and TLS/SSL protection.

Explore the OSI reference model and its seven-layer architecture, including how layers, data flow, and protocols enable secure, structured communication and troubleshooting across networks.

Define cloud computing per NIST as on-demand, network-accessible resources pooled for rapid provisioning with minimal management, covering SaaS, PaaS, IaaS, and deployment models public, private, hybrid, community.

cloud systems meter resources like storage, bandwidth, and active user accounts, providing transparency for providers and consumers; elasticity, virtualization, and pay-per-use models drive scalable, simple, cost-efficient expansion.

Mitigate malicious insider risks by enforcing independent third-party audits, clear ownership, handling and labeling policies, background checks, and strict access controls across cloud and on-premises environments.

Create policies, set scan targets, launch scans, and read results with vulnerability severities from critical to low, then apply patches in the nessus simulation.

Observe dynamic mac address table entries and ARP behavior, examine who has requests, and learn the three-way handshake while generating traffic and capturing packets with a tcap dump.
