Glossary of Terms

  • Network TAPs: Hardware tools that allow you to access and monitor your network traffic by copying data packets and sending them to monitoring devices for analysis.
  • OT Environment: Stands for Operational Technology environment. It refers to the hardware and software used to change, monitor or control physical devices, processes, and events in the enterprise.
  • IT Environment: Refers to the composite of hardware, software, network resources, and services required for the existence, operation, and management of an enterprise IT infrastructure.
  • Cybersecurity: The practice of protecting systems, networks, and programs from digital attacks.
  • Packet: A small amount of data sent over a network, such as a LAN or the Internet. Similar to a real-life package, each packet includes a source and destination as well as the content (or data) being transferred.
  • Network Interface Card: A hardware component that connects a computer to a network.
  • Zero Trust Frameworks: A security concept centered on the belief that organizations should not automatically trust anything inside or outside its perimeters and instead must verify anything and everything trying to connect to its systems before granting access.
  • Inline Blocking Devices: Security devices that are placed directly in the flow of network traffic and have the ability to stop, divert or alter traffic.
  • Out-of-band Devices: Security devices that operate separately from the main network data path and are used for network management and security tasks.
  • Bypass TAP: A network TAP that can redirect network traffic in the event of a device failure, ensuring network availability even during device maintenance or downtime.
  • Wiretapping Technology: A method of monitoring and recording communication passing over a network, often used for security and surveillance purposes.
  • Data Diodes: A network appliance or device that allows data to travel in only one direction, used in guaranteeing the flow of information in one direction only, ensuring network segment isolation.
  • Aggregators: Devices that combine several network connections into a single channel, increasing bandwidth and redundancy.
  • Intrusion Prevention Systems (IPS): Network security appliances that monitor network and/or system activities for malicious activity and can prevent or block such activities.
  • Denial of Service (DDoS) Solution: A security solution designed to protect networks or servers from denial-of-service (DoS) or distributed denial-of-service (DDoS) attacks, where the servers are overloaded with requests, causing them to slow down or crash.
  • Network Detection Response (NDR): A security solution that uses artificial intelligence (AI) to detect and respond to threats across the network.
  • Firewall: A network security device that monitors and filters incoming and outgoing network traffic based on an organization's previously established security policies.
  • Network Uptime: The time during which a network is operational and available to users.
  • Packet-level Data: Detailed information about each individual packet that travels over a network, including its source, destination, and the data it contains.
  • Managed Service Providers (MSPs): Companies that remotely manage a customer's IT infrastructure and/or end-user systems, typically on a proactive basis and under a subscription model.
