Do you need to install security updates on SharePoint?
Although it is supported to install only those packages which include the security updates it is recommended to keep SharePoint Server fully updated by installing the latest SharePoint updates regardless of whether they’re security or non-security updates.
To ensure that after the installation, the SharePoint server is kept always updated, we must ensure that both the Windows Updates and specially the SharePoint Cumulative Updates are properly installed. To install the latest SharePoint Cumulative Updates in your farm, follow the following steps: Install the Cumulative Updates in the SharePoint Farm
SharePoint patching consists of two steps: applying the binaries on each server and running the SharePoint Products Configuration Wizard on each machine in the farm to finalize the installation by upgrading the SharePoint databases and other administrative tasks.
Which is the second update for SharePoint farm?
The second update is the language-dependent WSSLOC patch and covers all language packs, including English installations. Both updates are required to fully update the farm, although the language-dependent WSSLOC patch may not be released every month. KB 4011645 KB 4011112 KB 3203433
