Virtual desktop infrastructure (VDI) is a technology that hosts desktop operating systems on a central server, allowing users to access a full desktop environment remotely from any device over a network.
Term 907
Virtual Extensible LAN (VXLAN) is a network virtualization technology that uses encapsulation to create isolated, scalable, Layer 2 networks across a Layer 3 infrastructure.
Term 908
A virtual machine (VM) is a software-based emulation of a physical computer that runs an operating system and applications just like a real machine, but is isolated and managed by a hypervisor on a host system.
Term 909
A virtual network is a software-based network that connects computers, servers, and devices over the internet or within a cloud environment, simulating a physical network without requiring dedicated hardware.
Term 910
A Virtual Private Cloud (VPC) is a logically isolated section of a public cloud where you can run resources in a private, customizable network environment.
Term 911
Virtualization security is the practice of protecting virtualized environments including virtual machines, hypervisors, virtual networks, and related infrastructure from threats and vulnerabilities.
Term 912
A virus is a malicious software program that attaches itself to legitimate files or programs and spreads to other systems, often causing damage or stealing information.
Term 913
A VLAN (Virtual Local Area Network) is a logical grouping of network devices that behave as if they are on the same physical network segment, regardless of their actual physical location.
Term 914
A Virtual Private Cloud (VPC) is a logically isolated section of a cloud provider's network where you can launch and manage resources like servers and databases with complete control over IP addressing, subnets, route tables, and security.
Term 915
A VPC endpoint is a private connection that allows resources inside a Virtual Private Cloud to access supported AWS services or external networks without going over the public internet.
Term 916
VPC peering is a direct network connection between two virtual private clouds that allows them to communicate using private IP addresses as if they were part of the same network.
Term 917
A VPN (Virtual Private Network) creates a secure, encrypted tunnel between your device and a remote server, protecting your data and hiding your online activity.
Term 918
A VPN creates an encrypted tunnel over a public network to securely connect remote users or sites to a private network.
Term 919
A vulnerability is a weakness in a system, network, or software that could be exploited by a threat to cause harm or unauthorized access.
Term 920
A vulnerability assessment is a systematic review of security weaknesses in an information system, evaluating if the system is susceptible to any known vulnerabilities, assigning severity levels, and recommending remediation or mitigation.
Term 921
Vulnerability management is the continuous process of identifying, classifying, prioritizing, and remediating security weaknesses in an organization's IT environment.
Term 922
Vulnerability scanning is an automated process that identifies security weaknesses in systems, networks, and applications by comparing them against known vulnerability databases.
Term 923
A Web Application Firewall (WAF) is a security tool that filters, monitors, and blocks HTTP traffic to and from a web application to protect it from common attacks.
Term 924
A Wavelength Zone is a small, physically separate data center location within a metropolitan area that provides ultra-low latency for edge computing and 5G applications.
Term 925
Weighted routing is a traffic management technique that distributes network requests across multiple servers or paths according to assigned numerical weights, allowing for controlled, uneven load distribution.
Term 926
A set of best practices and design principles for building secure, high-performing, resilient, and efficient cloud infrastructure.
Term 927
WEP (Wired Equivalent Privacy) is an outdated wireless security protocol that encrypts data using the RC4 cipher and a static key, but is easily broken.
Term 928
Wi-Fi Protected Access (WPA) is a security standard designed to secure wireless networks by encrypting data and controlling access, replacing the older and less secure WEP standard.
Term 929
A network security feature designed to simplify the process of connecting devices to a Wi-Fi network by using a push button or PIN instead of entering the full password.
Term 930
A wildcard mask is a sequence of 32 bits used alongside an IP address to define which bits must match and which are ignored for routing, access control, or network matching purposes.
