28 cards. Read the term and the definition here. The deck at the top of this page is optional.
- dBm
- A logarithmic absolute-power measure referenced to one milliwatt, distinct from a unitless dB ratio or antenna gain relative to an isotropic reference.
- Link budget
- A stated model combining transmit, gain, loss and receiver assumptions to evaluate a communication path, requiring real environmental and regulatory validation.
- Capacity requirement
- A measurable demand and concurrent-user/application condition that a wireless design must support, distinct from received-signal coverage alone.
- Passive survey
- An authorized observation method listening to relevant WLAN transmissions under its stated scope, without itself proving successful client authentication or application use.
- Spectrum observation
- A measurement of relevant RF energy behavior that can support interference hypotheses, distinct from automatic decoding or identification of every transmitting device.
- Fast BSS transition
- A supported802.11r-related method reducing relevant security-transition work, whose actual interruption and compatibility depend on client and deployment conditions.
- Forwarding architecture
- The actual local, tunneled or other supported path carrying client data, which cannot be inferred solely from where the management interface resides.
- SAE
- A password-authenticated key-establishment mechanism associated with WPA3-Personal, distinct from eliminating every later session-key handshake or implementation risk.
- Protected management frames
- Protection for relevant robust802.11 management frames under supported association/security conditions, not a guarantee against every radio or control-frame disruption.
- Monitor-mode coverage
- The actual802.11 traffic visible to a compatible adapter on its selected band/channel and placement, not simultaneous proof of every network event.
- Least Privilege
- The principle that users and systems should be granted only the minimum access rights necessary to perform their tasks, reducing the potential damage from accidents or malicious activity.
- Separation of Duties
- A control that divides critical tasks among different individuals so that no single person can complete a sensitive action alone, helping to prevent fraud and errors.
- Role-Based Access Control (RBAC)
- An access control model where permissions are assigned to roles rather than individual users, and users are assigned to roles based on their job responsibilities.
- Multi-Factor Authentication (MFA)
- An authentication method that requires two or more independent credentials from different categories (something you know, have, or are) to verify a user's identity.
- Authentication
- The process of verifying the identity of a user, device, or system, typically through credentials such as passwords, tokens, or biometrics.
- Authorization
- The process of determining what actions or resources an authenticated entity is permitted to access, often enforced through access control policies.
- Single Sign-On (SSO)
- A mechanism that allows a user to log in once and access multiple applications or systems without re-entering credentials, improving usability and centralizing access control.
- Encryption
- The process of converting plaintext into ciphertext using an algorithm and a key, so that only authorized parties can read the original information.
- Symmetric Encryption
- An encryption method that uses the same secret key for both encryption and decryption, offering speed but requiring secure key distribution.
- Asymmetric Encryption
- Encryption using a suitable public-key scheme and a corresponding private key for decryption. Authenticated key distribution and the specified padding/protocol remain essential; signatures and key agreement are distinct constructions.
- Hash Function
- A digest construction mapping input to an output under its defined algorithm, with cryptographic versions designed for appropriate resistance properties. Password storage needs a suitable salted password-hashing/KDF scheme rather than a bare fast digest.
- Digital Signature
- An electronic signature that uses asymmetric cryptography to verify the authenticity and integrity of a message or document.
- Access control
- The policies and mechanisms that determine who can access which systems, data, or facilities and under what conditions.
- Security Information and Event Management (SIEM)
- A system that collects, aggregates, and analyzes log data from various sources to detect security incidents and support compliance reporting.
- Incident Response
- A structured approach to handling security incidents, typically including preparation, detection, containment, eradication, recovery, and lessons learned.
- Business Continuity Plan (BCP)
- A document that outlines how an organization will continue critical operations during and after a disruption, including strategies for recovery and restoration.
- Disaster Recovery Plan (DRP)
- A plan focused on restoring IT infrastructure and operations after a disaster, including backup restoration and recovery time objectives.
- Backup
- The process of copying data to a secondary location or medium to enable recovery in case of data loss or corruption.
