Network

/ˌaɪ-piː-ˈɛsɛk/

n. “The armored lanes of your network traffic.”

IPSec, or Internet Protocol Security, is a suite of protocols designed to secure IP communications by authenticating and encrypting each IP packet in a data stream. It operates at the network layer, meaning it can protect all traffic crossing an IP network, from simple emails to complex enterprise applications. Its primary goals are confidentiality, integrity, and authenticity of the data in transit.

/ˌviː-piː-ˈɛn/

n. “Your private highway across the public internet.”

A VPN, or Virtual Private Network, is a technology that creates a secure, encrypted tunnel between your device and a remote server, allowing data to travel safely over untrusted networks like the internet. By masking your IP address and encrypting your traffic, VPNs protect your online identity, prevent eavesdropping, and can bypass geographic restrictions on content.

/ˈvɔɪp/

n. “Your phone, but over the internet instead of wires.”

VoIP, or Voice over Internet Protocol, is a technology that allows voice communications and multimedia sessions to be transmitted over IP networks, such as the internet, rather than traditional circuit-switched telephone lines. It converts analog audio signals into digital data packets, sends them over a network, and then reassembles them into sound at the receiving end, enabling phone calls, video calls, and conferencing entirely online.

/ˌsiː-diː-ˈɛn/

n. “A network that delivers content at the speed of thought.”

CDN, or Content Delivery Network, is a distributed network of servers strategically placed across the globe to deliver web content—such as HTML pages, images, videos, and scripts—quickly and reliably to users, regardless of their location. Instead of all requests going to a single origin server, a CDN caches content at edge locations, reducing latency, load times, and the chance of downtime.

/ˌdiː-diː-ˈoʊ-ɛs/

n. “When too many people knock at once and the door falls off.”

DDoS, short for Distributed Denial of Service, is a type of cyber attack where multiple systems—often compromised computers, IoT devices, or botnets—flood a target server, network, or service with massive amounts of traffic. The goal isn’t necessarily to steal data or break encryption; it’s to overwhelm resources, disrupt normal operation, and make services unavailable to legitimate users.
