Physical Domain in Software

Mitigation Efforts

• Physical hardware cannot be changed in the field
• Vendors build in “Survivability features”
• Microcode is the most common used tool for mitigations
• Other firmware is also used
• “Chicken bits” to disable / change behavior
• Some issues are best mitigated in software
• Mitigations are not always possible/reasonable and almost difficult and time-consuming to engineer

Prevention

Pre-silicon

Post-silicon
