Virtual Desktop Infrastructure

Virtual Desktop Infrastructure (VDI) is a technology that allows users to access and interact with a virtualized desktop environment hosted on remote servers or data centers, rather than on local physical devices such as desktop computers or laptops. VDI enables users to access their desktop environments from any device with an internet connection, providing flexibility, […]

Virtual Patching

Virtual patching refers to a security practice where temporary security controls or mitigations are applied to vulnerable systems or applications to protect them from known or zero-day vulnerabilities before a permanent patch is available or applied. Virtual patching is typically implemented through security technologies such as web application firewalls (WAFs), intrusion detection/prevention systems (IDS/IPS), or

Virtual Private Network

A VPN, or Virtual Private Network, is a technology that enables users to create a secure and encrypted connection over a less secure network, typically the internet. By using a VPN, users can establish a private and encrypted connection to a remote server, which then acts as a proxy, encrypting all data transmitted between the

Virtual Private Server

A Virtual Private Server (VPS) is a virtualized server environment created within a larger physical server infrastructure, which allows users to have dedicated resources and control over their own virtualized server instance. Unlike shared hosting, where multiple users share resources on the same physical server, a VPS provides users with greater autonomy, flexibility, and control

Voice Phishing

Voice Phishing, also known as Vishing, is a type of social engineering attack that uses voice communication channels, such as phone calls or VoIP (Voice over Internet Protocol) systems, to deceive individuals into divulging sensitive information, such as personal identification numbers (PINs), passwords, credit card numbers, or other confidential data. In a voice phishing attack,

Vulnerability

A vulnerability, in the context of cybersecurity, refers to a weakness or flaw in a computer system, network, software application, or hardware device that could be exploited by attackers to compromise the security of the system or to cause unintended consequences. Vulnerabilities can exist at various levels of the technology stack, including the operating system,

Vulnerability Assessment

Vulnerability Assessment is a systematic process of identifying, quantifying, and prioritizing vulnerabilities in software, hardware, networks, systems, and applications. The goal of vulnerability assessment is to assess the security posture of an organization’s IT infrastructure, identify weaknesses that could be exploited by attackers, and recommend remediation measures to mitigate or eliminate security risks. Key aspects

Vulnerability Scan

A vulnerability scan is a systematic examination of a computer system, network, or application to identify security weaknesses, potential vulnerabilities, and misconfigurations that could be exploited by attackers. Vulnerability scanning is an essential part of proactive cybersecurity practices and helps organizations assess their overall security posture. Here’s how vulnerability scanning typically works: Discovery: The scanning

Vulnerability Scanning

Vulnerability scanning is a security practice used to identify and assess security vulnerabilities and weaknesses within computer systems, networks, applications, and infrastructure. It involves automated or manual scans of systems and networks to detect known security flaws, misconfigurations, and potential points of exploitation that could be targeted by attackers. Key aspects of vulnerability scanning include:
