This chapter covers the importance of software updates. It may seem like a boring topic, but keeping software up to date is essential to good security. We also talk about how a provider can implement updates without interrupting your service. You'll understand how those updates have prevented issues in the past and where to look for new SAP notes, which detail fixes. You should be able to ask intelligent questions about their update policy to make sure it's as aggressive as you need it to be.
Here we start talking about the actual threats a data center will face and security controls they can implement to lower their risk. This chapter covers the physical servers, network cables, and buildings that make cloud computing possible. We discuss how they prevent damage that would interrupt your service and unauthorized access that could compromise your data. You'll come away with knowledge about how data centers should work, the questions you should ask, and how you can secure your own premises so your access points are as secure as your cloud environment.
