We’ve just published a Technical White Paper called KernelCare: Live Kernel Patching for Linux. It covers what KernelCare is, how it works and why you need it. We give an overview of setting up custom patch servers, both within and without firewalls, and we show what the patch management GUI looks like. We explain what delayed and sticky patches are, take a quick look at automating patch monitoring (through Nagios, Zabbix or the REST API) and show how to integrate with Rapid7 Nexpose.
It’s a great overview of KernelCare and a good, compact source of reference information. You can get a copy here.
