NFV - ✔️ ✔️ Aims to replace hardware-based network appliances NFV - ✔️ ✔️ Virtualizes network functions and running them on standard servers, reducing the need for dedicated hardware appliances. NFV - ✔️ ✔️ Functions deployed as Virtual Network Functions (VNF's) and can be dynamically deployed and scaled NFV - ✔️ ✔️ Optimize network infrastructure, reduce hardware dependence, and streamline network service deployment NFV - ✔️ ✔️ Useful for service providers, telecom operators, and orgs with complex network requirements Southbound API - ✔️ ✔️ Used to communicate between the control plane and data plane Northbound API - ✔️ ✔️ Communicate between control plane and application/management systems Southbound API - ✔️ ✔️ OpenFlow, NETCONF, and gRPC Northbound API - ✔️ ✔️ RESTful APIs, WebSockets, and custom appliaction-specific APIs Southbound API - ✔️ ✔️ Control plane instructs the data plane on how to handle network traffic Northbound API - ✔️ ✔️ Provide way for external applications, services, or orchestrators to request network services, retrieve network status, and manipulate network behavior. Southbound API - ✔️ ✔️ Used to communicate with physical or virtual network devices. Can configure, manage, and monitor Chef - ✔️ ✔️ Uses code written in Ruby and a specialized Domain-Specific Language (DSL) Ansible - ✔️ ✔️ Uses YAML-based playbooks, while also using JSON for data serialization during task execution and communication. Nova (Compute) - ✔️ ✔️ Provides foundation for handling the compute resources of a cloud. Enables creation, scheduling, and management of VM instances across a cluster of nodes. Neutron (networking) - ✔️ ✔️ Manages network resources in an OpenStack cloud. Provides the ability to create and manage virtual networks, routers, load balancers, and other network services.

NIST SP 800-125B Virtualization Components - ✔️ ✔️ Covers various components such as host systems, guest systems, management interfaces, and virtual networks NIST SP 800-53 Control Baselines - ✔️ ✔️ Guidelines for tailored security measures based on the organization risk profile and the sensitivity of the information being protected. (low, medium, and high) NIST SP 800-125B Isolation and Segmentation - ✔️ ✔️ Importance of maintaining strong isolation between VMs to prevent unauthorized information disclosure or unauthorized access. NIST SP 800-53 Continuous Monitoring - ✔️ ✔️ Monitoring of security controls to ensure ongoing compliance and effectiveness NIST SP 800-125B Configuration Management - ✔️ ✔️ Emphasizes the need for secure configuration of hypervisor and virtual machine settings, including parameters related to memory allocation, CPU scheduling, and network configurations. NIST SP 800-53 Risk Management Framework (RMF) - ✔️ ✔️ Provides a structured approach for managing and mitigating information security risks. NIST SP 800-125B Secure Deployment - ✔️ ✔️ Provides recommendations for practices involving patch management, secure boot processes and hardware-based security features NIST SP 800-53 Security and Privacy Overlay - ✔️ ✔️ Provides controls and guidance to help organizations address privacy requirements alongside security requirements. NIST SP 800-125B Virtualization Vulnerabilities - ✔️ ✔️ Discusses issues that may arise due to virtualization, such as side-channel attacks and "VM escape" attacks.
