The new software can also send out email alerts whenever some unwanted activity takes place."You can specify any kind of alert you care about," Chiu said. For instance, an administrator can set up an alert for whenever anyone deletes more than 10 VMs.
Typically, administrators rely on SIEM (Security Information Event Management) systems for getting such system alerts, but that software tends not to work well for virtualized environments, Chiu said.
"Trying to configure a SIEM to report on what is happening in a virtual environment is difficult. Our customers told us 'We want that to come from you'," Chiu said.
Drawing from a new security hardening guide for vSphere released by VMware, HyTrust Appliance now has three times as many server configuration security checks and remediation operations than it had before. It can also now work with Intel's Intel Trusted Execution Technology (Intel TXT), so "you can determine whether your hardware platform is trusted, before you move your workload into that environment," Chiu said.
HyTrust Appliance 3.5 is now available. The HyTrust Appliance Enterprise Edition costs US$1,050 per CPU socket for each ESX or EXSi host, as well per $30,000 per appliance. The company also offers a downloadable community edition for no cost, which manages up to three hosts.
