What is the Problem?

clock-img1

For servers to be secure, kernels must be up to date. This requires frequent updates and reboots.

  • Unpatched kernels make servers vulnerable to attacks;
  • Enterprises often wait weeks or months until the next scheduled reboot cycle;
  • Delays lead to compliance issues and critical security risks.

Cost Considerations with Traditional Kernel Updates

Operational Costs:

Due to maintenenance windows and admin costs, timely updates and server reboots are difficult. Factors to consider:

  • Number of servers that need to be updated;
  • % of servers that will have restart issues during a reboot;
  • Damage control from issues arising within the framework of discovered vulnerability and a fix;
  • Being non-compliant due to running unpatched software prior to next maintenance window;
  • Number of Admins needed to perform updates;
  • Days/hours spent by Admins performing repetitive maintenance, planning and updates, as opposed to more strategic IT initiatives.

Business Costs:

Various business units are affected by the downtime during the update Factors to consider:

  • Business and opportunity cost of application downtime;
  • Stakeholders are involved in downtime planning;
  • Risk factors related to security issues if they arise.

How KernelCare Works

Our security experts, with a deep knowledge of kernel development, monitor all Linux security lists 24x7x365;

Once they notice a vulnerability that affects the supported kernel, they promptly prepare a security patch;

Patch is compiled in a binary format and is deployed to KernelCare distribution servers;

KernelCare agent checks for new patches every 4 hours and if any found, it downloads it and updates kernels without the reboot.
