# Baseline
|
|
|
|
A baseline consists of taking a snapshot of certain parts of a system to **compare it with a future status to highlight changes**.
|
|
|
|
For example, you can calculate and store the hash of each file of the filesystem to be able to find out which files were modified.\
|
|
This can also be done with the user accounts created, processes running, services running and any other thing that shouldn't change much, or at all.

## File Integrity Monitoring
|
|
|
|
File Integrity Monitoring (FIM) is a critical security technique that protects IT environments and data by tracking changes in files. It involves two key steps:
|
|
|
|
1. **Baseline Comparison:** Establish a baseline using file attributes or cryptographic checksums (like MD5 or SHA-2) for future comparisons to detect modifications.
|
|
2. **Real-Time Change Notification:** Get instant alerts when files are accessed or altered, typically through OS kernel extensions.
