CLI

The Command Line Interface (CLI) is the means used to administer and configure the GCap. It is the set of commands in text mode.

FQDN

The Fully Qualified Domain Name (FQDN) refers to the host.domain name.

GCap

The GCap is the detection probe of the Trackwatch solution. It recovers the network flow from the TAP, reconstructing the files that it sends to the GCenter.

GCenter

GCenter is the component administering the GCap and performing the analysis of the files sent by the GCap.

gview

Account name intended for an operator.

gviewadm

Account name intended for a manager.

MTU

The Maximum Transfer Unit (MTU) is the largest packet size that can be transmitted at one time, without fragmentation, over a network interface.

OTP

The One Time Password (OTP) is a single-use password defined on the GCenter.

RAID1

RAID 1 consists of using n redundant disks. Each disk in the cluster contains exactly the same data at all times, hence the use of the word "mirroring".

RAID5

RAID 5 uses several hard disks (at least 3) grouped together in a cluster to form a single logical unit. The data is duplicated and allocated to two different disks.

setup

Account name intended for a system administrator.

SIGFLOW

The detection engine, also called Sigflow, is responsible for rebuilding the files and is also one of the engines for intrusion detection.

TAP

The Test Access Point (TAP) is a passive device enabling a network flow to be duplicated.
