Next steps

This guide introduced features available in the Arm architecture which can provide robust defenses for complex software stacks. We have looked at the pointer authentication and branch target identification extensions, which can be used to defend against ROP and JOP attacks. We also looked at how memory tagging can be used to detect and locate potential vulnerabilities before they are exploited.

Next you might want to learn about Arm’s TrustZone technology, another feature available in the Arm architecture.

The knowledge in this guide, and in the TrustZone guide, will be useful to you as you design your own complex systems. Enabling you to decide which combination of technologies you should deploy to protect different assets in the system.
