On a scale of 1 to 10 in importance, security always rates close to a 10 in setting up and managing a vSphere environment. Well, maybe not—but it should. Even though VMware has increased the capabilities and features that come with its products, these same products and features must fit within the security policies applied to other servers. Most of the time, ESXi and vCenter Server fit easily within those security policies, but occasionally the process is a bit of a challenge. This chapter examines the tools and techniques that will help you ensure that your vSphere environment appropriately follows the security policies of your organization.
