ºÚÁϺ£½Ç91Èë¿Ú

ºÚÁϺ£½Ç91Èë¿Ú’s automated patch management for Linux lets you configure a delay when performing updates for major and minor Linux versions. Each of these options has its own setting where you can specify the number of deferral days. This setting controls how long before future updates are made available to the device. In addition, you can set a grace period for minor Linux updates. When a minor update becomes available, this setting controls how long users can defer updates. As that grace period approaches its expiration, automatic reminders appear more frequently and eventually users can't dismiss them.

You can save time by using ºÚÁϺ£½Ç91Èë¿Ú’s default patch policies and policy groups that are preconfigured and ready to use. See Create Default Patch Policies and Policy Groups below.

ºÚÁϺ£½Ç91Èë¿Ú also provides a universal browser patch policy that keeps Google Chrome up to date for macOS, Windows, and Linux. See Create a Universal Browser Patch Policy.

Contact your Account Manager if you’re interested in adding patch management to your package or to learn more about the solution. Pricing for patch management is located at /pricing.

Create Default Patch Policies and Policy Groups

If your organization hasn't yet configured any macOS, Windows, or Linux patch management policies or policy groups, you can save time by loading a set of default patch policies and policy groups, enforcing security patches on a large number of managed devices.

A policy group helps you quickly and efficiently roll out preconfigured policies using deployment rings. Deployment rings are configured with sane defaults. The deployment ring names match these policy group names, as well as control how and when an update is applied:

• Vanguard - Deploy automated upgrades inside your IT Department. 
• Early Adoption - Deploy automated upgrades to early adopters outside of IT.
• General Adoption - Deploy automated upgrades to general users in your company.
• Late Adoption - Deploy automated upgrades to remaining users in your company.

To create default Linux patch policies and policy groups:

1. Log in to the .Ìý
2. Go to DEVICE MANAGEMENT > Policy Management.
3. Select Patch Management, then select the OS tab.
4. If you haven’t yet configured a patch policy or patch policy group, click Load Default Policies & Policy Groups to create four out-of-the-box default policy groups. Each policy group contains three preconfigured deployment ring policies that are automatically bound to the group.
5. Review the preconfigured settings for the Linux default policies. 

6. (Optional) Select the policy you just created and select the Device Groups tab.
7. Select one or more device groups where you'll apply this policy. For device groups with multiple OS member types, the policy is applied only to the supported OS.
8. (Optional) Select the Devices tab.
9. Select one or more devices where you'll apply this policy.
10. Click save.
11. After the policy runs, you can view detailed results for a specific device:
    • Go to DEVICE MANAGEMENT > Devices.
    • Select the Devices tab, then select the applicable device.
    • Select the Policy Results tab, and click View to see more details. An Exit Status of 0 means the policy ran successfully.
