Term 423
A reverse proxy is a server that sits in front of one or more backend servers, intercepting client requests and forwarding them to the appropriate server, then returning the server's response to the client as if it came from the reverse proxy itself.
Term 424
A reverse shell is a type of remote access attack where the target machine initiates an outbound connection back to the attacker, allowing the attacker to execute commands on the compromised system.
Term 425
RFID uses radio waves to wirelessly identify and track tags attached to objects, enabling automatic data capture without line-of-sight.
Term 426
Risk is the possibility that an event or action will negatively affect an organization's ability to achieve its goals, often measured in terms of likelihood and impact.
Term 427
Risk acceptance is a risk management strategy where an organization acknowledges a potential risk but decides to tolerate it without taking active measures to reduce or eliminate it.
Term 428
Risk appetite is the amount of risk an organization is willing to accept in pursuit of its objectives, defining the boundaries for decision-making.
Term 429
Risk assessment is the process of identifying, analyzing, and evaluating potential threats to an organization's assets to determine the likelihood and impact of those threats, and to decide on appropriate treatment measures.
Term 430
Risk avoidance is a risk management strategy that involves eliminating any activity, process, or technology that introduces a specific risk, rather than trying to reduce or accept it.
Term 431
Risk management is the process of identifying, assessing, and controlling threats to an organization's capital, earnings, and operations, including IT systems and data.
Term 432
Risk mitigation is the process of reducing the likelihood or impact of a potential security threat to an acceptable level through specific controls and actions.
Term 433
A risk register is a formal document that lists and tracks all identified risks to an IT project, system, or organization, including their assessed impact, probability, and planned responses.
Term 434
A risk score is a numerical value that represents the level of risk associated with a given asset, threat, or vulnerability in a security context.
Term 435
Risk tolerance is the amount of risk an organization or individual is willing to accept in pursuit of its objectives, defining the boundary between acceptable and unacceptable losses.
Term 436
Risk transfer is the practice of shifting the financial burden of a potential loss to another party, typically through insurance or contracts.
Term 437
Risk-based access is a security model that dynamically adjusts access permissions based on the assessed risk of each access request, rather than granting a static level of access to all users.
Term 438
Risk-based vulnerability management is a cybersecurity approach that prioritizes the fixing of security weaknesses based on the level of risk they pose to an organization's specific environment, rather than just addressing all vulnerabilities in the order they are found.
Term 439
A rootkit is a type of malware that hides its presence and the presence of other malicious software on a computer, often by modifying the operating system itself.
Term 440
A route is a path that data takes through a network from one device or network to another, determined by routing protocols and configured rules.
Term 441
Route 53 is Amazon Web Services’ cloud-based Domain Name System (DNS) web service that translates human-readable domain names into IP addresses and routes end-user requests to internet applications.
Term 442
Route summarization is a technique that combines multiple network routes into a single, more general route advertisement to reduce the size of routing tables and improve network performance.
Term 443
A route table is a set of rules, called routes, that determine where network traffic from a subnet or virtual network is directed.
Term 444
A router is a networking device that connects different networks together and directs data traffic between them by choosing the best path for data to travel.
Term 445
A Router Advertisement is a message sent by a router on a network to inform devices about the router's presence and provide them with essential configuration information for communication.
Term 446
The Router ID is a unique 32-bit identifier assigned to a router running the OSPF routing protocol, used to distinguish it from other routers in the network.
Term 447
A router-on-a-stick is a network configuration where a single router interface is used to route traffic between multiple VLANs by connecting to a switch through a trunk link.
Term 448
A routing table is a data set stored in a router or host that contains information about network paths and is used to determine where to forward data packets.
Term 449
Recovery Point Objective (RPO) is the maximum acceptable amount of data loss measured in time, defining how recent data must be to resume operations after a disruption.
Term 450
RSA is a cryptographic algorithm that uses a pair of keys—a public key and a private key—to secure data in transit and verify identities.
