What is a botnet?
A botnet is a network of compromised computers controlled remotely by an attacker, often used to launch large-scale cyberattacks such as DDoS assaults, spam campaigns, and credential stuffing.
What is a CDN (Content Delivery Network)?
A Content Delivery Network (CDN) is a geographically distributed network of servers that caches and delivers web content from locations closest to users, improving performance, reliability, and security.
What is a Man-in-the-Middle (MITM) Attack?
A Man-in-the-Middle (MITM) attack is a cyberattack where an attacker secretly intercepts and potentially alters communications between two parties who believe they are communicating directly with each other.
What is ICMP?
ICMP (Internet Control Message Protocol) is a network-layer protocol used by network devices to send error messages and operational information, most commonly known for powering the ping and traceroute utilities.
What is IP spoofing?
IP spoofing is a technique where an attacker forges the source IP address in packet headers to disguise their identity, impersonate another system, or bypass network security controls.
What is OSI Model?
The OSI (Open Systems Interconnection) model is a conceptual framework that standardises how different networking protocols and technologies communicate across seven distinct layers.
What is TCP/IP?
TCP/IP (Transmission Control Protocol/Internet Protocol) is the foundational suite of communication protocols that powers the internet, governing how data is addressed, transmitted, routed, and received across networks.
What is UDP?
UDP (User Datagram Protocol) is a lightweight, connectionless transport-layer protocol that sends data packets called datagrams without establishing a prior connection or guaranteeing delivery.
What is WordPress Multisite?
WordPress Multisite is a feature that allows administrators to run a network of multiple WordPress sites from a single WordPress installation, sharing the same codebase and database while introducing unique security considerations.
