Updating kernel modules for the
Cloud Workload Protection
Linux agents

Whenever a new Linux kernel update is released, the
Cloud Workload Protection
agent for that platform needs to be updated to support the new kernel. To make the process more efficient, the kernel modules of the
Cloud Workload Protection
agent can now be updated by using Linux repository.
Ensure that the agents can connect to the Symantec repository server (https://linux-repo.us.securitycloud.symantec.com) to download the kernel module updates.
Whenever you run the
yum update
command on a RHEL, Amazon Linux, Oracle Linux, or CentOS system, the command also looks for new
Cloud Workload Protection
agent packages. If an update is available, the latest kernel module is downloaded and the agent is updated automatically. After the kernel module is updated, you must restart the instance for the update to take effect.
Alternatively, you can update the agent kernel module of only the
Cloud Workload Protection
agent by running the following command in the instance. Open a terminal window with root privilege and type:
sudo yum update sdcss-kmod
For the Ubuntu systems, type the following commands:
  • To refresh and update local package database:
    sudo apt-get clean
    sudo apt-get update
  • To upgrade to the latest
    Cloud Workload Protection
    kernel module:
    sudo apt-get install --only-upgrade sdcss-kmod
If you update the operating system kernel modules, you must also update the corresponding kernel module update for the agent. Without the compatible kernel modules, the
Cloud Workload Protection
agent may not work properly and some features may be disabled.
