© 2012 CloudPassage Inc. 48 Cloud Security Challenges Inconsistent Control (you don’t own everything) –The only thing you can count on is guest VM ownership Elasticity (not all servers are steady-state) –Cloud-bursting, stale servers, dynamic provisioning Scalability (handle variable workloads) –May have one dev server or 1,000 number-crunchers Portability (same controls must work anywhere) –Nobody wants multiple tools or IaaS provider lock-in

© 2012 CloudPassage Inc. 71 Other Cool Halo/API Tricks Set password reset requirements for a server user account. Find server accounts that don't have passwords (it happens) Find those spooky root-owned setuid files. Generate alerts if PID files go missing. Generate an alert if someone is in a group they shouldn't be in (like wheel). Generate massively detailed reports of server configuration status for auditors (keep 'em busy for weeks). Get a report of every server that a user *does not* have an account on. Get a report of every server that a user has an account on. Get alerted if a new cloud server gets created. Learn what process that TCP/IP port is bound to. Make sure that init.d startup scripts can't be tampered with by non-root users. Make sure that services are not running with excessive privileges. Monitor servers to detect old user accounts that should have been cleaned up, but might have gotten missed. Many, many more at community.cloudpassage.com
