Execute Disable Bit for Intel® Processors
The Execute Disable Bit is a hardware-based security feature that can reduce exposure to viruses and malicious-code attacks, and prevent harmful software from executing and propagating on the server or network.
The bit is located in the processor specification page (ARK), under the security and reliability.
- Go to Intel Product Information.
- Enter the processor number in the search box. To get the number of the processors, refer to How to Identify my Intel® Processor.
- In the product page of the processor, go to Security and Reliability section and find the Execute Disable Bit field as shown below.
|Note||Newer processors such as 11th Generation Intel® Core™ Processors consider the Execute Disable Bit feature to be Legacy and thus it may not be listed in the processor specification page (ARK). However, it is still supported.|
