2023-06-13 · 4 min read · System Design

MIT 6.033 (Computer System Engineering) covers 4 parts: Operating Systems, Networking, Distributed Systems, and Security.

This is the course note for Part IV: Security. And in this section, we mainly focus on common pitfalls in the security of computer systems, and how to combat them.

To build a secure system, we need to be clear about two aspects:

security policy (goal)
threat model (assumptions on adversaries)

MIT 6.033 (Computer System Engineering) covers 4 parts: Operating Systems, Networking, Distributed Systems, and Security.

This is the course note for Part I: Operating Systems. And in this section, we mainly focus on:

How common design patterns in computer system — such as abstraction and modularity — are used to limit complexity.
How operating systems use virtualization and abstraction to enforce modularity.
