Introduction to Post Mortem Analysis In the dynamic field of cybersecurity, understanding and mitigating risks is a continuous endeavor. One of the most critical processes for this is the post mortem analysis. After a security breach, this structured review serves as an indispensable tool to dissect the incident thoroughly. It aims to illuminate the root…

Understanding User and Entity Behavior Analytics The importance of advanced analytical tools cannot be overstated. User and Entity Behavior Analytics (UEBA) is emerging as a cornerstone in contemporary network security strategies, offering a nuanced method to monitor and understand the actions of both users and devices within a network. UEBA’s strength lies in its ability…

What is a CVE Score? A CVE score refers to the severity rating assigned to a Common Vulnerabilities and Exposures (CVE) entry using the Common Vulnerability Scoring System (CVSS). This score helps security professionals assess the risk level of a vulnerability and prioritize remediation efforts. How CVE Scoring Works (CVSS) The CVSS (Common Vulnerability Scoring…

What is the MITRE Attack Matrix? The MITRE ATT&CK Matrix is a structured framework that categorizes cyber adversary tactics, techniques, and procedures (TTPs) used in real-world attacks. Developed by MITRE Corporation, it helps cybersecurity professionals understand how attackers operate and improve their threat detection, response, and defense strategies. The matrix format visually organizes: Tactics (Columns):…

What is the MITRE ATTACK Framework? The MITRE ATT&CK (Adversarial Tactics, Techniques, and Common Knowledge) Framework is a publicly available knowledge base that documents adversary tactics and techniques based on real-world observations. Developed by MITRE Corporation, ATT&CK helps cybersecurity professionals understand and defend against cyber threats by mapping out the various steps attackers take to…

What is a Security Operations Center (SOC)? A Security Operations Center (SOC) is a centralized unit within an organization responsible for continuously monitoring, detecting, analyzing, and responding to cybersecurity threats. The SOC functions as the nerve center for an organization’s cybersecurity efforts, ensuring that security incidents are identified and managed before they can cause significant…

What is a content security policy? A Content Security Policy (CSP) is a security feature implemented by web developers to prevent a variety of attacks, like Cross-Site Scripting (XSS) and data injection attacks. It works by specifying which sources of content are allowed to load on a website. Think of it as a set of…

What is address resolution protocol (ARP)? Address Resolution Protocol (ARP) is a network protocol used to map an IP address (logical address) to a device’s MAC address (physical address) within a local network. It operates at the Data Link Layer (Layer 2) of the OSI model and is essential for enabling communication between devices in…

What is a keylogger? A keylogger (short for keystroke logger) is a type of surveillance or malicious software (or hardware device) that records every keystroke made on a computer or mobile device. Keyloggers are often used to capture sensitive information like usernames, passwords, credit card numbers, and personal messages, typically without the user’s knowledge. Types…

What is ethical hacking? Ethical hacking, also known as penetration testing or white-hat hacking, refers to the practice of intentionally probing computer systems, networks, or applications for vulnerabilities to identify and fix security flaws. Ethical hackers use the same methods and tools as malicious hackers but do so with the permission and authorization of the…

What is SIEM? SIEM (Security Information and Event Management) is a cybersecurity solution that provides organizations with the ability to monitor, detect, analyze, and respond to security incidents in real time. It combines Security Information Management (SIM) and Security Event Management (SEM) capabilities into a single platform to provide a comprehensive view of an organization’s…

What is an intrusion detection system (IDS)? Intrusion Detection refers to the process and technology used to identify unauthorized access, misuse, or anomalies in a computer system or network. Intrusion Detection Systems (IDS) play a critical role in cybersecurity by monitoring and analyzing network traffic or system activities to detect suspicious behavior and potential security…
