GTT Explains: Networking, Security & Cloud Glossary

Agentic Artificial Intelligence (AI) is the name given to AI systems that can act autonomously by making decisions and pursuing goals with minimal human intervention.

Internet of Things (IoT) refers to the network of physical objects embedded with sensors and connectivity, enabling them to collect, exchange and act on data over the internet without human intervention.

A cyber attack is a deliberate attempt by criminals to break into a computer system to steal data, disrupt business operations for profit or cause general harm.

A Distributed Denial of Service (DDoS) attack is a targeted cyberattack designed to overwhelm a digital service, such as a website, application, or network, by flooding it with a massive volume of traffic.

Firewalls are hardware or mixed hardware/software systems that filter out untrustworthy network traffic before it can cause problems within your network.

A Virtual Private Network (VPN) is a service that creates a secure connection between your device and the wider internet or your office network.

API security reduces the risk of unauthorized access to your company’s data by protecting Application Programming Interfaces (APIs), which connect software applications and the data they need to function.

Cloud infrastructure includes the hardware and software that power cloud services across public, private, or hybrid environments.

Dynamic Host Configuration Protocol (DHCP) helps networks stay efficient by automatically assigning IP addresses to connected devices.

Dedicated internet access can be explained as your organization has a private, exclusive connection to the broader internet.

A Google VPP is a pre-vetted internet service provider (ISP) that meets strict criteria set by Google.

Identity and access management (IAM) is a comprehensive framework that combines policies, processes and technologies to ensure the right people have access to the right digital resources at the right times and for the right reasons.

Internet protocol transit (IP transit) is a commercial service that enables a network to exchange global internet traffic by routing data through an Internet Service Provider’s (ISP) backbone.

Network security protects your business network from cyberattacks and intrusions by malicious actors, forming a cornerstone of modern business practice and protection.

Secure Access Service Edge (SASE) is a modern approach to networking and security that unifies cloud-based protection, connectivity and user access in a framework that integrates SD-WAN and SSE solutions.

Software-Defined Wide Area Networking (SD-WAN) is a cloud-first approach to manage and optimize wide area networks using intelligent software.

SIP trunking is the modern way enterprises deliver voice, video, and messaging across a secure, high-performance data network—replacing traditional fixed telephone circuits with virtual “trunks” that ride over IP.

VoIP technology is transforming business communications by cutting costs while adding advanced features not found in traditional analog phone systems.
