ISC2 Certified Secure Software Lifecycle Professional (CSSLP) Practice Question

You are designing a multi-tenant SaaS platform where customer code currently runs as separate processes under the same operating-system account. To better apply the least common mechanism principle, which architecture change most effectively minimizes shared mechanisms between tenants?

  • Set the sticky bit on the shared /tmp directory so tenants cannot delete one another's files.

  • Run each tenant inside an individual container that uses separate namespaces and cgroups.

  • Introduce a load balancer that distributes all tenants' traffic to a shared application pool.

  • Keep a single database but create tenant-specific tables with group-based ACLs.
