FileZilla Server/FZPES Common Terminology

2FA
In a second factor authentication method users are granted access to a service or an application after successfully presenting two or more pieces of information. Such factors usually are based on something you know, have or are.
Certificate chain
The certificate chain is a series of certificates, including the TLS certificate, intermediate certificates, and
root certificates. It forms a hierarchical chain of trust, ensuring the authenticity of the TLS certificate.
CIDR Notation
Classless Inter-Domain Routing (CIDR) is a representation of an IP address and its associated network
mask.
Client
client is a computer application that you use to connect your local computer to FileZilla Server/FileZilla Pro Enterprise Server. FileZilla, FileZilla Pro and FileZilla Pro Command Line are clients. Using it, you can add, delete, or edit files and/or directories on FileZilla Pro Enterprise Server.
Distinguished Name
A structured, textual representation used to uniquely identify the entity associated with a digital certificate. It consists of a comma-separated sequence of Relative Distinguished Names (RDNs). Each RDN is a plus-separated set of attribute-value pairs, where each attribute is separated from its value by an equal sign. Example: CN=example.com, OU=IT, O=Example Corp, L=New York, ST=NY, C=US
Download
When files are transferred from FileZilla Server/ FileZilla Pro Enterprise Server to a local machine.
FTP
File Transfer Protocol is a basic method for moving files between local and remote computers.
See FTP for more information.
FTPS
File Transfer Protocol with TLS is a secure version of File Transfer Protocol (standard FTP).
File transfers are encrypted between a client and FileZilla Pro Enterprise Server. See FTPS for
more information.
NAT
Network Address Translation. It is a method that modifies IP header information in transit, mapping an
internal IP address space to an external one, commonly implemented in routers.
PEM
Privacy Enhanced Mail. PEM is a file format commonly used for storing certificates, certificate chains,
and private keys. PEM-encoded files are base64-encoded ASCII, and they often have extensions like
.pem, .crt, .cer, and .key.
PKCS#11:
A Public-Key Cryptography Standard, also known as “Cryptoki”. It is an API used to communicate with
cryptographic security tokens such as smart cards, USB keys, and Hardware Security Modules (HSMs)
Port
A port is a logical construct that identifies a specific process or a type of network service.
Private key
The private key is a cryptographic key used to secure communications. It works in conjunction with the
certificate chain, which includes the TLS certificate, to establish secure connections.
Recursive
In terms of FileZilla Server/ FileZilla Pro Enterprise Server, a recursive action on a directory affects all of its
subdirectories and files in them and so on.
Service
It is a background process executed by the operating system.
SFTP
SSH File Transfer Protocol is a method that FileZilla Server/ FileZilla Pro Enterprise Server can use to access
and transfer files on a server. It is based on Secure Socket Shell protocol, and it uses a server’s
SSH port.
SSH
Or Secure Shell, is a cryptographic network protocol used for secure data communication.
TLS
Transport Layer Security (TLS) encrypts communications between a client and FileZilla Server/ FileZilla Pro En-
terprise Server. This keeps the files that you’re transferring secure from eavesdroppers while
they’re in transit between your local computer and the server. TLS is used in FTPS connections.
UNC
Universal Naming Convention. A path format for identify resources in a network. On Windows the
format is \\server-name\resource-name.
Upload
When files are transferred from a local machine to FileZilla Server/ FileZilla Pro Enterprise Server.
URI
Universal Resource Identifiers: strings containing names or addresses identifying a resource
on the internet.
User ID
Also sometimes referred to as a User Name or User Identification. This is the string of text
that an application, server, or website recognize as belonging to a particular person. Some-
times your user ID will be your email address; sometimes just a string of characters, for exam-
ple janesmith98352.
X.509
A standard defining the format of a digital certificate containing an identity (a hostname, or an organization, or an individual) and a public key. It might be signed by a certificate authority or self-signed, and it
is used for securing communication over a network.

Windows Service
A Windows Service is an executable application that the operating system runs in background.
