  • Verify you've met all the deployment requirements
  • Verify your Linux system meets all the hardware and software requirements
  • Have experience working with Linux systems
  • Have root or admin permissions to install the sensor
  • Have necessary permissions in CertCentral

See Discovery workflow and permissions and Sensor installation requirements.

Instruction summary:
Extract the .tar.gz file to a specified folder, run ./start.sh, then follow the prompts to activate the sensor.

Install sensor

Download the sensor from your CertCentral account

  1. In the sidebar menu, click Discovery > Manage Discovery.

  2. On the Scan page, click Add sensor.

  3. On the Set up a sensor page, under step 1 Download a discovery sensor in the Linux section, click Download.

Create the installation directory and install the sensor

  1. As a root user, log on to your Linux server.

    For example:

    $ su
    Password: *****************
    #

  2. Create the installation directory

    For example:

    mkdir ccsensor

  3. Go to the installation directory and extract the sensor .tar.gz file.

    For example:

    cd ccsensor
    tar -xzvf
    <sensor-file>.tar.gz

    Where ccsensor is the installation directory and <sensor-file> is the name of the file.

Sensor activation note:
You can activate the sensor now or later. However, you must activate the sensor before you can use it to set up a scan. If you choose to activate the sensor later, see Linux: Activate a sensor.

Activate the sensor

  1. Go to the installation directory and run start.sh.

    For example:

    cd ccsensor
    ./start.sh

    Where ccsensor is the installation directory.

  3. Select the division you want to assign the sensor to.

    If you don't have divisions, we return the name of the organization for your account.

  4. When asked, enter a sensor name.

You're ready to set up and run a scan using this sensor. See Set up and run a scan.

If you're using multiple sensors, you may want to rename the sensors to make tracking/identifying them easier. See Rename the sensor.
