DAY 5: Learning Objectives

- Understand the concept of authentication and authorization
- Learn how to spot potential opportunities for Insecure Direct Object References (IDORs)
- Exploit IDOR to perform horizontal privilege escalation
- Learn how to turn IDOR into SDOR (Secure Direct Object Reference)

and we have to know the concepts
- **Authentication:** The process by which you verify who you are. For example, supplying your username and password.
- **Authorization:** The process by which the web application verifies your permissions. For example, are you allowed to visit the admin page of a web application, or are you allowed to make a payment using a specific account?

DAY 6:
learning objectives
- The principles of malware analysis
- An introduction to sandboxes
- Static vs. dynamic analysis
- Tools of the trade: PeStudio, ProcMon, Regshot

There are two main branches of malware analysis: **static** and **dynamic**. Static analysis focuses on inspecting a file without executing it, whereas dynamic analysis involves execution. We will come to these shortly.

sandboxes
In cyber security, sandboxes are used to execute potentially dangerous code. Think of this as disposable digital play-pens. These sandboxes are safe, isolated environments where potentially malicious applications can perform their actions without risking sensitive data or impacting other systems.
