If you’ve heard of PowerVS, you’re probably aware of the top-notch cybersecurity offered by security managed service providers like CloudFirst. But there are a few main aspects of PowerVS cybersecurity you should understand before choosing it for your foundation. CloudFirst has the answers.
IBM PowerVS (Power Virtual Server) has many great qualities and is in itself secure. But there is one key aspect it does not cover: the security of your applications running on top of it.
- It offers no protection for your system beyond the foundation.
- You’re responsible for monitoring, managing, and updating.
- Your house doesn’t have any doors, walls, or windows.
Would you want to live in a house that didn’t have any walls? Our best guess would be no.
But let’s back up a minute and discuss what security PowerVS does offer before digging any further into what it’s missing.
Understanding PowerVS Security
The short answer? Very secure. The long answer? You’re going to want some help from a trusted provider like CloudFirst. Read on.
IBM explains that PowerVS security “combines the immutable nature of snapshots and Cloud Object Storage’s ability to find the last known good copy.”
PowerVS provides protection from ransomware and other cyber threats without the need for expensive security products and services. “Immutable object storage is an IBM Cloud Object Storage feature that preserves records and maintains data integrity in a write-once-read-many (WORM), non-erasable and non-rewritable manner,” says IBM.
This feature protects against deletion or modification until the end of retention periods and the removal of any legal holds.
In basic terms, that means immutable files (in a WORM context) cannot be modified or deleted without explicit permission, which means the integrity of those files is maintained by design, preventing them from being infected by ransomware.
IBM PowerVS also includes an Activity Tracker integration that enables compliance with regulatory and internal audit requirements. “The Activity Tracker records user-initiated activities that change the state of a service in IBM Cloud and identifies security incidents, including unauthorized access,” explains Eapen Valakuzhy for IBM.
PowerVS also integrates with IBM Cloud’s Hyper Protect Crypto Services, which offer technical assurance that even IBM administrators can’t access the client’s keys.
Remember, all of this only applies to PowerVS IBM Cloud itself. PowerVS is automatically secure, while whatever apps or services you put on top of it are not. You’re responsible for maintaining the security of any applications attached to PowerVS.
This is common for shared responsibility models such as the one you’d be entering into with PowerVS.
The Shared Responsibility Model in PowerVS Cybersecurity
The shared responsibility model is a security and compliance framework that outlines which parties are responsible for which aspects of a system’s security. That includes hardware, infrastructure, endpoints, data, configurations, settings, operating system, network controls, and access rights.
In the case of IBM Cloud PowerVS, the responsibilities for managing the lifecycle of, operating, and securing products are shared between IBM and the customer. Having a clear delegation of responsibilities across these areas is critical for keeping everything running efficiently and effectively, without running the risk of any sections falling through the cracks.
What are you responsible for when using PowerVS?
End users of PowerVS (which is part of the IBM Hybrid Cloud product family) are responsible for incident and operations management, change management, identity and access management, security and regulation compliance, and disaster recovery across:
- data
- applications
- operating systems
- physical networks and devices (datacenter core)
- facilities and data centers
PowerVS and the end user share the responsibility of:
- virtual and bare metal servers
- virtual storage
- virtual networks
- identity and access management and security and regulation compliance of physical servers and memory
IBM handles the management of:
- physical storage
- hypervisor (software that can run multiple virtual machines on a single physical machine)
- physical networks and devices, top of rack and spine
- incident and operations management, change management, and disaster recovery for physical servers and memory
The way all these responsibilities shake out can leave you with a lot of maintenance to handle on your own in terms of cyber security for PowerVS, even with the support of IBM.
And on top of that, there are so many options for how to go about securing your data and applications. The research, the trial and error, the countless products clamoring to call themselves the best solution. And in the meantime, your system is vulnerable and your team is stressed trying to operate without the tools they need.
We don’t want that chaos for you and we’re sure you don’t, either. Luckily, there is another way.

Block out those drafts with the right reinforcements
You don’t have to live in a house with no walls, and you shouldn’t have to worry about the maintenance of those walls, either.
To recap, today we walked through:
- PowerVS security, which offers foundational security but not application security
- the implications of entering into a shared responsibility model, where there are lots of balls to juggle
- how you can avoid dropping any of those balls and improve your PowerVS security using CloudFirst services
