Applying Security Patches
All software has bugs that must be patched to prevent bad things from happening. When new bugs are discovered, the details are often published or leaked to the media. People with less than wholesome intentions can use this information to craft exploits by taking advantage of these bugs with the knowledge that most systems are out-of-date and not protected.
With this in mind, it is important to keep on top of the security landscape and have a planned approach to patch management. This section will focus on the subject of securing your cloud fleet of servers and services as it relates to keeping your systems up-to-date.
As part of a shared security model, the cloud provider will secure the infrastructure, and the cloud customer will be required to address security concerns based on the service model they are operating under. A complete patch management approach must be developed, implemented, and adhered to in order to prevent a security breach.
