SMTP relay
SMTP relay: The process of transferring an email from one mail server to another. In this context, the term “relay” describes the act of passing along the email. SMTP (Simple Mail Transfer Protocol) is the protocol used for sending email across the internet. While SMTP relays are essential for email delivery, they can be exploited […]
SOCKS
SOCKS: A protocol that facilitates the routing of network packets between clients and servers through a proxy server. This protocol establishes a TCP connection that can transmit any kind of data securely, providing a layer of protection between the user and the internet. SOCKS is used where more granular control at the application layer of […]
Software-Defined Networking (SDN)
Software-Defined Networking (SDN): A networking architecture that uses software to control and manage network infrastructure rather than relying on hardware-based controls. It is used to improve network agility, scalability, and flexibility. Examples include using software-defined networking controllers, virtualizing network functions, and implementing network automation tools.
Software-Defined Security (SDS or SDSec)
Software-Defined Security (SDS or SDSec): An approach to security that uses software to define and enforce security policies across an organization’s network. It is used to provide centralized, flexible, and scalable security management. Examples of SDS solutions include network security virtualization and software-defined perimeter.
Span Port (Mirror Port)
Span Port (Mirror Port): A feature on network switches that allows the duplication of network packets from one or more ports to a designated monitoring port, enabling network administrators to analyze traffic for various purposes, such as performance monitoring, troubleshooting, and security analysis. Tools like network analyzers or intrusion detection systems are often connected to […]
Spanning Tree Algorithm (STA)
Spanning Tree Algorithm (STA): A mathematical process used in network communications to create a topology of interconnected switches or bridges that is loop-free, ensuring there are no circular paths through which packets can endlessly loop. This is critical for the stability and efficiency of network communications, as it eliminates the risk of broadcast storms and […]
