A Denial of Service (DoS) attack is an attempt to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the Internet. DoS attacks typically flood a network with excessive requests, overwhelming the network and preventing legitimate users from accessing IT resources or services. This type of attack does not compromise user accounts, hijack privileges, or duplicate user credentials, but it does effectively deny service to legitimate users.

Continuous Data Protection (CDP) is a data protection method that continuously captures or tracks data modifications and stores changes independently of the primary data. A CDP appliance works by intercepting all writes to the production volume. It splits each write operation into two copies: one copy is written to the production volume, and the other is sent to a separate storage location where the changes are logged. This enables recovery to any point in time and helps ensure data integrity.

A software-defined data center (SDDC) is an architecture that extends virtualization concepts such as abstraction, pooling, and automation to all of the data center's resources and services. In an SDDC, IT resource components like computing, networking, storage, and security are all virtualized, except for the commodity hardware used to create resource pools. This virtualized environment enables more efficient resource management and scalability.
