In the context of cybersecurity, alert fatigue means the diminished capacity of a security team to effectively distinguish, prioritise and act on meaningful security alerts because the volume, repetition or noise of alerts has desensitised the analysts.
-
Anomaly is any data point or behaviour that deviates from the norm or usual pattern. Anomaly detection, or outlier detection, is a method to identify these abnormalities in an efficient way. This helps organizations and security team to catch errors, threats, or attack attempts at the earliest to enhance overall protection.
-
An apex predator is like a lion or shark—top of the food chain. In cybersecurity, it means the most powerful and dangerous attackers.
-
An organization’s attack surface is made up of different kinds of weaknesses. These are usually grouped into three main categories: Digital Attack Surface, Physical Attack Surface, and Social Engineering Attack Surface.
-
Cloud Infrastructure Entitlement Management, or CIEM, is a way to help you manage and control who has access to what in your cloud environments. It makes sure that the right people and services can reach the right resources — and nothing more.
-
Command and Control, commonly known as C2, is the infrastructure and mechanisms used by attackers to remotely control compromised systems inside a target network.
-
Common Vulnerabilities and Exposures is referred to as CVE. This open-access database lists known cybersecurity vulnerabilities in network, hardware, and software systems.
-
Cyber extortion is essentially online blackmail of businesses. Here, the attackers break into systems and gain access to data or accounts without permission.
-
A cyber threat can be any malicious activity executed or initiated by criminals to: Damage data, Steal confidential information, or Disrupt digital operations.
-
Cyber warfare can affect government networks, power grids, financial systems, or military communications, and create effects similar to a situation that has devolved into armed conflict.
-
Cyberterrorism is when attackers use digital weapons to cause real-world chaos. We’re not talking about stealing credit cards or holding files for ransom – that’s regular cybercrime.
-
Cyberwarfare is when a country attacks another digitally to disrupt systems, steal data, or cause harm. Instead of soldiers, the fight uses malware, phishing, and hacking. It’s quiet but can be as damaging as regular war.
-
Data at rest sits idle in storage systems like hard drives, databases, backup tapes, cloud buckets, archived files.
-
A data breach is a security incident in which unauthorized individuals or entities gain access to confidential or sensitive data held by your organization.
-
Learn what data exfiltration means in cybersecurity, the signs of data exfiltration, and the difference between data exfiltration and a data breach.
-
Data in motion is exactly what it sounds like information on the move. It’s those emails flying across the internet, files uploading to cloud drives, video calls streaming, databases syncing, apps talking to each other.
-
Data in use is data that’s actively being worked on, whether it’s loaded into RAM, crunched by the CPU, pulled from a database, edited in a document, or used by an app.
-
Data Masking ensures that the original data, like personal details or financial records, stays safe while still allowing systems and applications to work normally.
-
Understand what data protection is, why it matters, key regulations, and best practices to safeguard personal and business data from misuse.
-
Learn what data security is, why it matters, key types, and how organizations protect sensitive data from breaches, loss, and cyber threats.
-
Deception decoys are, by definition, a subset of deception technology. Decoys pretend to be any legitimate system, network, application, or data asset to attract cyber attackers.
-
DevSecOps is a software development methodology that incorporates security into every stage of the DevOps process – from planning and development, to deployment and maintenance.
-
DFIR, short for Digital Forensics and Incident Response, is the process of investigating and responding to cybersecurity incidents. It helps you understand how an attack happened, what systems were affected, and how to recover safely.
-
A digital footprint refers to the data trail you leave behind when using the internet—such as the websites you visit, emails you send, or information you submit online.
-
Digital forensics is a dedicated branch of forensic science that focuses on finding, preserving, and presenting digital evidence. Digital forensics is important for solving cyber crimes such as hacking, data leaks, and identity theft.
-
DLP systems detect policy violations by inspecting content (file types, keywords, metadata) and context (user behavior) across endpoints, networks, and cloud services.
-
Learn what dwell time means in cybersecurity, why attackers stay hidden, and how reducing this risk window improves threat detection and response.
-
A false negative occurs when a security control overlooks genuine malicious activity and labels it as benign. The threat slips through unchallenged, so no alert fires and no defensive action is taken.
-
A false positive arises when a security control mistakes normal, harmless activity for malicious behavior. The tool raises an alert, analysts investigate, yet no real threat exists.
-
Encryption method that protects individual files rather than entire drives. Works by applying cryptographic algorithms to specific documents based on how sensitive they are.
-
Digital forensics involves examining electronic evidence after security breaches occur. Investigators look at compromised systems to understand what happened and which information attackers accessed.
-
Full-Disk Encryption is a process that encrypts all data on your storage drive, not just selected files. This includes: Operating system files, Application data, User documents, and Temporary files and caches.
-
SCADA stands for Supervisory Control and Data Acquisition. Learn what it means and how it monitors and controls industrial processes.
-
A Secure Web Gateway (SWG) filters web traffic to block threats, enforce policies, and protect users. Learn its definition and how it works.
-
In enterprise security, sensitive data encompasses a broad spectrum of information types, including sensitive personal data, personally identifiable information (PII), regulated data, and critical corporate data.
-
SIEM (Security Information and Event Management) is a system that collects, analyzes, and correlates security data from across networks to detect threats and respond faster.
-
A signature is a unique identifier derived from known malicious code or behavior—such as a specific sequence of bytes, file hash, or pattern of network activity.
-
Learn what SMTP is, how it works for email delivery, and why it’s essential for sending and receiving emails securely across the internet.
-
SOAR is a cybersecurity approach and technology platform designed to help security teams manage and respond to security incidents more efficiently.
-
Discover what TCP/IP means in cybersecurity, its role in secure data transfer, and why it’s vital for protecting networks from cyber threats.
