Install the Traps Agent for Linux

Traps for Linux is designed to protect Linux servers and operates transparently in the background as a system process. After you install Traps for Linux, it is typically not necessary to interact with the Traps agent; however, to perform common actions, such as initiating a manual check in with the Traps management service, you can use the command-line utility (also available for Mac and Windows) named Cytool. Cytool is available in the /opt/traps/bin/cytool directory and must be run as root or with root permissions.
Before installing Traps on a Linux server, verify that the system meets the requirements described in Traps for Linux Requirements.
If you intend to use SELinux, make sure to enable it before you proceed with the Traps installation. This ensures that Traps disables any injection-based modules which cause compatibility issues. If you later enable SELinux, you must reinstall Traps to avoid any compatibility issues.
You can then install Traps using software distribution tools that support Linux such as Satellite or Chef, or you can manually install Traps using the following workflow:
  1. Download the Traps installation script from the Traps management service.
    The Traps management service saves the installation script using the name you provided to identify the package.
  2. Copy the installation package to the Linux server on which you want to install the Traps software.
    For example, to copy the file securely from a local machine to the Linux server:
    user@local ~
    $ scp                                100%   21MB   1.2MB/s   00:18
  3. Log on to the Linux server and install the Traps software.
    1. Run the install script as root or with root permissions.
      For example:
      user@local ~
      $ ssh

      [*] Starting Traps security services (systemd)
      The script installs the files for the Traps app for Linux in the /opt/traps folder with the Cytool utility available at /opt/traps/bin/cytool.
      After the Traps agent successfully connects to the server for the first time and retrieves a valid license, the agent begins protecting the Linux server.
  4. Use the Traps Agent for Linux.
    For a list of available options, enter the cytool command without any arguments or with -h or --help.
