The power of cyber resiliency at your core

At Dell Technologies, we often talk about how security is ingrained into our product DNA. What we mean is that security is never an afterthought — it’s never something that we build on after the product itself is complete.
Instead — and our Secure Development Lifecycle (SDL) is a key part of this — we continually design our products with past, current and future security threats in mind. And we supplement secure product development with external audits and continuous testing and evaluation to find and remedy vulnerabilities that do occur.
Dell’s commitment to customers
Attacks on the infrastructure layer, especially the firmware, are on rise. According to a Microsoft Security Signals report, more than 83% of enterprises have experienced at least one firmware attack in the past two years.
At Dell, we understand that securing the infrastructure layer is fundamental to protecting any IT environment against modern threats. Our cyber-resilient infrastructure has security built into every phase starting from the supply chain to the operation and eventual retirement of products. We are also committed to making sure any vulnerabilities or exposures found in the field, that could impact our products, get mitigated through rapid response on our end.
Let’s talk about how we secure our PowerEdge servers.
Cyber resiliency is key
Modern server platforms are highly complex, with hundreds of components — a lot of which require firmware for configuration and management of the component during the boot process and operation of the server.
Given the complexity of today’s platforms and the level of sophistication of cyberattacks, we recognize that it is not possible to prevent 100% of attacks. Some breaches are inevitable, especially when it comes to new devices and firmware, for example. Cyber resiliency — the ability to anticipate, withstand and recover from attacks — is therefore fundamental to surviving in this threat landscape.
At Dell, we use the NIST framework of Protect, Detect and Recover to guide our resiliency efforts. At the same time, the process of identifying and designing these capabilities is done through the zero-trust approach — with a focus on increasing the granularity of controls and checks in the systems — and by anticipating how our customers will want to use these capabilities while they are setting up their zero-trust IT environments and deployments.
Cyber resiliency built into PowerEdge
Dell PowerEdge servers offer cyber-resilient infrastructure by anchoring platform integrity to a silicon-based Root of Trust and using automated features to continuously protect the system during its operation.
Root of Trust: PowerEdge offers end-to-end boot resilience by enabling UEFI secure boot, which is anchored in our silicon-based platform Root of Trust. This immutable Root of Trust is the starting point of the chain of trust used to cryptographically authenticate the different pieces of firmware that get loaded on PowerEdge servers. Our secure boot helps to make sure that the firmware is coming from a trusted source and has not been tampered with in any way.
UEFI certificate customization: PowerEdge servers provide capabilities for complete customization of UEFI secure boot, giving system owners an option to avoid relying on third-party industry keys and industry certificate authorities. The NSA has recognized that fully customized UEFI secure boot offers the highest level of security and provides the best protection against threats. And it’s important to note that Dell was the first server vendor to provide these capabilities to customers.
CPU security
In addition to fully customizable UEFI secure boot, PowerEdge servers offer a complementary layer of protection against things like sleep attacks by enabling Intel Boot Guard and AMD Platform Secure Boot features. These features add robustness to the chain of trust process by verifying the firmware before it gets executed on the processor and eliminating attacks between time of check by UEFI secure boot and time of use of the firmware on the processor.
Drift detection: Beyond assuring boot integrity, PowerEdge can also lock down the system configuration and automatically detect drift in firmware versions and the configuration of the system. If drift is detected, PowerEdge can respond by automatically initiating rollback of the firmware and OS to a “known good” version.
Through these features, PowerEdge servers offer end-to-end boot resilience by protecting against attacks on the firmware, detecting any ongoing attack on firmware and/or system configuration, and automatically recovering from attacks by rolling the system configuration and firmware back to a safe, verified version. What’s also important to note is that this happens with no manual intervention at machine speed, which is critical for minimizing system downtime.
But Dell goes even further
When it comes to the firmware, it's important to reiterate that Dell is committed to providing rapid response and mitigation to CVEs. What you might not know is that the majority of attacks occur because known vulnerabilities are not being patched in the field.
We don’t want to leave our customers vulnerable, which is why we’re always working to improve our service-level agreements (SLA) for updates and patches that help mitigate new threats as quickly as possible.
Resiliency is just one small facet of Dell’s overall security stance. Take time to learn more about what we’re doing to protect your devices, your data, and your business. PowerEdge, like the rest of the Dell fleet of products, has a broad feature set that goes beyond resiliency — and is capable of meeting your risk tolerance requirements and regulatory and compliance needs.
