Term 331
OAuth is an open standard for access delegation that allows users to grant third-party applications limited access to their resources without sharing their credentials.
Term 332
OCSP (Online Certificate Status Protocol) is a method used to check whether a digital certificate is still valid or has been revoked in real time.
Term 333
A one-time password is a temporary, single-use code that authenticates a user for one login session or transaction.
Term 334
OpenID Connect is an identity layer on top of OAuth 2.0 that allows applications to verify a user's identity and obtain basic profile information in a standardized way.
Term 335
Operational Technology (OT) refers to the hardware and software systems that monitor, control, and manage physical devices, processes, and infrastructure in industries like manufacturing, energy, and utilities.
Term 336
Origin access control is a security mechanism that restricts access to a network, system, or resource based on the verified identity or attributes of the requesting entity.
Term 337
OSPF is a link-state routing protocol used to find the best path for data packets to travel across IP networks, like a smart GPS that recalculates routes when traffic changes.
Term 338
An OSPF adjacency is a logical neighbor relationship formed between two OSPF routers that have completed a series of hello and database exchange processes, enabling them to share routing information and maintain a consistent view of the network topology.
Term 339
An OSPF area is a logical grouping of routers and networks within an OSPF routing domain, used to control routing traffic and improve scalability.
Term 340
OSPF authentication is a security mechanism that verifies the identity of routers exchanging routing information within an OSPF network, preventing unauthorized or malicious routing updates.
Term 341
OSPF cost is a metric used by the Open Shortest Path First routing protocol to determine the best path for data packets to travel through a network, based on the characteristics of each link.
Term 342
OSPF metric is a cost value assigned to each route in an Open Shortest Path First network, used to determine the best path for data packets.
Term 343
An OSPF neighbor is another router that has been directly discovered through OSPF Hello packets and is willing to exchange routing information to build a network topology map.
Term 344
OSPF network type defines how the Open Shortest Path First routing protocol operates on a given interface, determining neighbor discovery, adjacency formation, and the election of designated routers.
Term 345
Operational Technology (OT) is hardware and software that monitors and controls physical devices, processes, and infrastructure in industrial environments.
Term 346
An Outbound ACL is a set of rules applied to traffic leaving a network interface that decides which packets are allowed to exit and which are blocked.
Term 347
Privileged Access Management (PAM) is a security framework that controls, monitors, and audits access to critical systems and accounts with elevated permissions.
Term 348
Pass-the-hash is a cyberattack where an attacker captures the hash of a user's password and uses it to authenticate to other systems without ever knowing the actual password.
Term 349
Passive reconnaissance is the process of gathering information about a target system or network without directly interacting with it, using publicly available sources and stealthy observation.
Term 350
A set of rules designed to enhance computer security by encouraging users to create strong, secure passwords and store them properly.
Term 351
Password spraying is a type of brute-force attack where an attacker tries a few commonly used passwords against many different accounts to avoid account lockouts.
Term 352
Passwordless authentication is a method of verifying a user's identity without requiring them to enter a password, using alternative factors like biometrics, hardware tokens, or one-time codes.
Term 353
Patch management is the process of identifying, acquiring, testing, and deploying software updates (patches) to fix vulnerabilities, bugs, or improve performance in IT systems.
Term 354
A set of security rules that any company that handles credit card payments must follow to protect cardholder data from theft and fraud.
Term 355
The Payment Card Industry Data Security Standard is a set of security requirements designed to protect credit card data during storage, processing, and transmission.
Term 356
A penetration test is a simulated cyberattack against a computer system, network, or application to identify security weaknesses that an attacker could exploit.
Term 357
Penetration testing is a simulated cyberattack on a computer system, network, or application to find security weaknesses before real attackers can exploit them.
Term 358
Perfect forward secrecy is a property of secure communication protocols that ensures that even if a long-term private key is compromised, past session keys and the messages they encrypted remain safe from decryption.
Term 359
Persistence is the set of techniques attackers use to maintain long-term access to a compromised system even after reboots or credential changes.
Term 360
A Personal Identification Number (PIN) is a short numeric code used to verify a user's identity before granting access to a system, device, or account.
