SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are cryptographic protocols designed to secure internet communications by encrypting data between users and servers. TLS is the modern, more secure version of SSL, providing stronger encryption and authentication mechanisms. How SSL/TLS Works 1. Handshake Process - The client and

Two-Factor Authentication (2FA) is a security process that requires users to verify their identity using two different authentication factors before accessing an account or system. These factors typically tend to fall into three categories: * Something You Know - Passwords or PINs. * Something You Have - A mobile device, security key,

User and Entity Behavior Analytics (UEBA) is a cybersecurity approach that leverages machine learning and advanced analytics to detect anomalous behavior in users and systems. Instead of relying on predefined security rules, UEBA identifies suspicious activities by analyzing patterns, behaviors, and deviations from normal operations. How UEBA Works * Behavioral Baselines

Vishing, also known as voice phishing, is a social engineering attack where cybercriminals use phone calls or voice messages to deceive individuals into sharing sensitive information, such as login credentials, financial details, or personal data. Unlike traditional phishing, which relies on email or text messages, vishing exploits human trust by

A cybersecurity vulnerability is a weakness or flaw in a system, software, or network that can be exploited by cybercriminals to gain unauthorized access, disrupt operations, or steal sensitive data. These vulnerabilities can stem from software bugs, misconfigurations, outdated systems, weak passwords, or human error. Common Types of Cybersecurity Vulnerabilities

Zero Trust is a cybersecurity framework that eliminates implicit trust within an organization’s network. Instead of assuming that users or devices inside the network are safe, Zero Trust requires continuous verification, strict access controls, and least privilege principles to prevent unauthorized access and cyber threats. Key Principles of Zero

The Defence Cyber Certification (DCC) is a cybersecurity scheme developed to raise the standards for digital protection across the UK defence supply chain. Introduced by the Ministry of Defence (MOD) in collaboration with IASME (the team behind Cyber Essentials), it’s part of a broader push to make cyber risk

Shadow SaaS (Software-as-a-Service) is a specific and high-velocity subset of Shadow IT where cloud-based applications are adopted by employees or departments without formal approval from IT, Security, or Procurement. While classic Shadow IT might include unauthorized hardware or local software, Shadow SaaS lives entirely in the browser and the cloud.

Shadow AI is the unauthorized adoption and deployment of Artificial Intelligence tools, Large Language Models (LLMs), and autonomous agents within an organization without explicit approval or oversight from IT and Security departments. While Shadow IT typically involves unmanaged applications (like Dropbox or Trello), Shadow AI is fundamentally different because the

Shadow Data refers to any corporate data that is created, stored, or shared outside of an organization’s central visibility and security controls. Unlike Shadow IT, which focuses on the unauthorized applications being used, Shadow Data focuses on the content itself—where it lives, who has access to it, and
