Fine-grained memory protection
November 2, 2023
In previous blog posts we have considered the damage, costs and underlying causes of memory unsafety. Having looked at conventional approaches to protecting processor systems we concluded that standard approaches such as MPUs, MMUs and privilege modes while having some value are limited in effectiveness.
We also noted that while languages like C/C++ give tremendous control to programmers there is also a lot of room for errors because of the use of pointers. Pointers are variables containing memory addresses.
