Defense in Depth
Defense in Depth is a cybersecurity strategy that involves deploying multiple layers of security controls and measures to protect against different types of threats and attacks, often including network segmentation, access controls, intrusion detection, and incident response.
Digital Forensics
Digital Forensics is the process of collecting, analyzing, and preserving digital evidence from computers, mobile devices, or other electronic media for investigative or legal purposes, often involving specialized tools and techniques for data recovery and analysis.
Denial of Service (DoS)
Denial of Service (DoS) is a type of cyber attack that involves flooding a network or website with traffic or requests, often causing the system to crash or become unavailable to users.
Distributed Denial of Service (DDoS)
Distributed Denial of Service (DDoS) is a type of cyber attack that involves using multiple compromised devices or systems to flood a network or website with traffic or requests, often causing the system to become unavailable or unusable.
Digital Signature
A Digital Signature is a type of electronic signature that provides proof of the authenticity and integrity of a digital document or message, often using cryptographic techniques to ensure non-repudiation.
Dumpster Diving
Dumpster Diving is a type of physical security breach that involves rummaging through an organization’s garbage or recycling bins to find sensitive or confidential information, often used for identity theft or fraud.
Data Classification
Data Classification is the process of categorizing data based on its sensitivity or importance to an organization, often used to determine appropriate security controls and handling procedures.
Digital Certificate
A Digital Certificate is a type of electronic document that verifies the identity of the owner of a public key, often used to secure online transactions and communications.
DNS Spoofing
DNS Spoofing is a type of cyber attack that involves redirecting or manipulating the Domain Name System (DNS) to redirect users to fake or malicious websites or to intercept communications.
Domain Name System (DNS)
The Domain Name System (DNS) is a protocol used to translate human-readable domain names (such as google.com) into IP addresses (such as 172.217.6.14) used by computers to communicate over a network.
Disaster Recovery
Disaster Recovery is the process of restoring and recovering IT systems and data after a disruptive event or disaster, often involving backup and recovery solutions, redundancy, and business continuity planning.
Data Masking
Data Masking is a technique used to hide or obscure sensitive or confidential data by replacing or obscuring the original data with a substitute, often used to protect data privacy and security.
Digital Rights Management (DRM)
Digital Rights Management (DRM) is a set of technologies and policies used to protect and manage digital content, often including access controls, encryption, and licensing agreements.
Data Encryption
Data Encryption is the process of converting plain text or data into a code or cipher that can only be deciphered with a key or password, often used to protect data confidentiality and privacy.
Digital Identity
Digital Identity is the representation of an individual or entity’s online or digital identity, often including personal information, user accounts, credentials, and online activity.
Device Management
Device Management is the process of managing and securing mobile devices, such as smartphones or tablets, used in an organization, often involving policies, controls, and mobile device management (MDM) software.
Digital Watermarking
Digital Watermarking is a technique used to embed a unique and invisible digital signature or identifier into digital media, such as images or videos, for copyright or authentication purposes.
Deep Packet Inspection (DPI)
Deep Packet Inspection (DPI) is a technique used to inspect and analyze network traffic at the packet level to detect and prevent security threats, often used by firewalls, intrusion detection and prevention systems, and network analytics tools.
Dark Web
The Dark Web is a hidden part of the internet that is not indexed by search engines and is only accessible through special software, such as Tor or I2P, often used for illegal activities, such as buying and selling illegal goods or services, or sharing sensitive or confidential information.
Data Leakage
Data Leakage is the unauthorized or accidental release of sensitive or confidential data to unauthorized parties, often caused by human error, negligence, or cyber attacks, such as data breaches or phishing.
Database Security
Database Security is the process of protecting and securing databases and their contents from unauthorized access, modification, or destruction, often involving access controls, encryption, and database activity monitoring.
Denial of Service (DoS)
Denial of Service (DoS) is a type of cyber attack that involves flooding a network or system with traffic or requests to overload and disrupt its normal operations, often resulting in service disruption or downtime.
Digital Forensics
Digital Forensics is the process of collecting, analyzing, and preserving digital evidence from computers, networks, or other digital devices, often used in criminal investigations, litigation, or incident response.
Data Loss Prevention (DLP)
Data Loss Prevention (DLP) is a set of policies, procedures, and technologies used to prevent or detect the unauthorized access, use, or transmission of sensitive or confidential data, often involving data classification, access controls, and data encryption.
Dual Factor Authentication (2FA)
Dual Factor Authentication (2FA) is a security process that requires users to provide two different types of authentication factors, such as a password and a biometric, to access a system or application, often used to enhance security and prevent unauthorized access.
Deception Technology
Deception Technology is a set of techniques and technologies used to deceive and mislead attackers and prevent or delay their progress in a network or system, often involving honeypots, decoys, or fake data.
Distributed Denial of Service (DDoS)
Distributed Denial of Service (DDoS) is a type of cyber attack that involves multiple computers or devices, often compromised by a botnet, to flood a network or system with traffic or requests and cause service disruption or downtime.
Decryption
Decryption is the process of transforming encrypted data back into its original, readable form, often requiring a decryption key or password to unlock the encrypted data.
Data Encryption
Data Encryption is the process of transforming data into a coded form using cryptographic algorithms, often used to protect sensitive or confidential data from unauthorized access or exposure, and to ensure data confidentiality and integrity.
Disaster Recovery Plan (DRP)
A Disaster Recovery Plan (DRP) is a set of policies, procedures, and strategies used to recover and restore normal business operations after a disruptive event, often including backup and recovery strategies, contingency plans, and incident response procedures.
Digital Identity
A Digital Identity is the unique representation of an individual or organization in the digital realm, often including personal or business information, credentials, and authentication factors, such as passwords, biometrics, or tokens.
