Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.
With enough magnification, a chip's physical structure reveals its secrets. CWE-1278 covers designs that do nothing to resist imaging based reverse engineering.
If a device cannot be patched, every bug found after shipping stays open for the device's whole life. CWE-1277 is the weakness behind many botnet recruits.
A hardware IP block can work perfectly and still be wired to its parent in a way that breaks security, such as a reset tied to the wrong source.
A session cookie without SameSite, or with SameSite=None, rides along on cross-site requests. Without other defenses, that opens the door to CSRF.
Secure boot checks the bootloader, then parks it in RAM. If that RAM is writable by others, the check proves nothing.
The key that unlocks a chip's debug features gets handed to every company in the supply chain. Each handoff is another place it can leak.
Sleep, hibernate and debug states change who may see what. If secrets are not wiped on the way in, they leak across the transition.
If security critical registers are not set to a known value at reset, the device has a window where its protections are in an unknown, insecure state.
SoC security tokens tell the chip what each agent may do. If they are generated wrongly, access control decisions are made on bad information.
