Requirements for Using Intel SGX
The BIOS must have an option to enable SGX. The Intel SGX option must be set to Enabled or Software Controlled in BIOS, depending on the system. PhoenixNAP BMC servers have this option already enabled. You must Install the Intel SGX Platform Software package.
What is BIOS SGX?
Intel® Software Guard Extensions (SGX) is a security technology built into Intel processors that helps protect data in use via unique application isolation technology. Selected code and data are protected from modification using hardened enclaves.
How do I know if SGX is compatible?
Find out if a specific processor supports Intel® SGX:
- Go to product specifications (ARK).
- Enter the processor number in the search specifications box in the top-right corner.
- On the product specification page of the processor, click Security & Reliability and look for Intel® Software Guard Extensions (Intel® SGX).
Do I need Intel SGX drivers?
Intel SGX software is required if SGX security is enabled in BIOS. See the release notes for installation instructions, supported hardware, what is new, bug fixes, and known issues.
How do I fix SGX disabled by BIOS?
Enabling the Intel Software Guard Extensions (SGX)
- From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > System Options > Processor Options > Intel Software Guard Extensions (SGX) and press Enter.
- Select a setting and press Enter. Enabled.
- Press F10.
What is Intel SGX used for?
Intel® SGX allows user-level code to allocate private regions of memory, called enclaves, which are designed to be protected from processes running at higher privilege levels. Only Intel® SGX offers such a granular level of control and protection.
Should I enable or disable SGX?
Generally, you shouldn’t disable Intel SGX under any circumstances. If you plan to use Intel SGX to help secure your applications and sensitive data, disablement should be completely avoided, as disablement offers no application or data protection whatsoever.
What is SGX motherboard?
Intel Software Guard Extensions (SGX) is a set of security-related instruction codes that are built into some Intel central processing units (CPUs).
Is Intel SGX safe?
SGX ensures that data is secure even if a computer’s operating system has been tampered with or is under attack. “For normal functioning, the SGX design allows the OS to interrupt the enclave execution through configurable hardware exceptions at any point,” the researchers outlined.
Does Intel still support SGX?
The Intel SGX feature has been removed from Intel 11th generation (or newer) CPUs, and support for SGX may be removed at some point on the new versions of Intel drivers or utility programs (e.g., the Intel SGX and Intel Management Engine driver and firmware).
Does AMD support Intel SGX?
Intel SGX does not exist on AMD platforms. AMD has their own version of it but PowerDVD does not support it. It is easier and cheaper to rip and play, or to get a standalone player.
What is Intel BIOS Guard support?
Intel BIOS Guard protects the BIOS flash from modification without platform manufacturer authorization, which helps defend the platform against low-level DOS (denial of service) attacks, and restores BIOS to a known good state after an attack.
Does Intel SGX affect performance?
(5) SGX imposes a heavy performance penalty upon switching between the application and the enclave, ranging from 10,000 to 18,000 cycles per call depending on the call mechanism used. This penalty affects server applications using SGX, as discussed in [3, 45].
What is Intel management engine driver?
It is a feature of the Intel Management Engine Interface (IMEI) driver that is compatible with your OS and the IME firmware on your device. The driver enables your PC to be controlled remotely through some specialized/specialized settings on the motherboard.
What is SGX ESXI?
SGX allows an application to “conspire” with the CPU to keep secrets from the guest OS and the hypervisor, thereby reducing risk. Some applications are starting to explore this functionality, and in vSphere 7 we expose it to VMs running virtual hardware version 17. We call it “vSGX.”
What is CFG lock?
CFG Lock is a BIOS setting that allows writing to a specific register, in this case MSR E2 (MSR = Model Specific Register). An MSR consists of one or more registers in blocks of instructions used to do certain tasks on a CPU. MTRs are also used to control CPU’s access to memory ranges.
What is enclave memory size?
Enclave Memory Size. This option sets SGX Enclave Reserve Memory Size. Click one of the following options: 32 MB. 64 MB.
Is Intel secure?
Intel is focused on ensuring the security of our customers computing environments. We are committed to rapidly addressing issues as they arise, and providing recommendations through security advisories and security notices. Security advisories are fixes or workarounds for vulnerabilities identified with Intel products.
What is SGX enclave size?
The size of the SGX enclave is fixed but is different depending on the processor model. Sizes range from 8 GB to 512 GB per processor. For a 2-socket ThinkSystem server, if enough DDR memory is installed, the system BIOS can reserve between 16GB and 1TB based on processor model installed.
What is TrustZone in arm?
Arm TrustZone technology offers an efficient, system-wide approach to security with hardware-enforced isolation built into the CPU. It provides the perfect starting point to establish a device root of trust based on PSA guidelines.
