# 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 is one of the most powerful techniques used to secure IT infrastructures and business data against a wide variety of both known and unknown threats.\
|
|
The goal is to generate a **baseline of all the files** that you want to monitor and then **periodically** **check** those files for possible **changes** (in the content, attribute, metadata, etc.).
|
|
|
|
1\. **Baseline comparison,** wherein one or more file attributes will be captured or calculated and stored as a baseline that can be compared against in the future. This can be as simple as the time and date of the file, however, since this data can be easily spoofed, a more trustworthy approach is typically used. This may include periodically assessing the cryptographic checksum for a monitored file, (e.g. using the MD5 or SHA-2 hashing algorithm) and then comparing the result to the previously calculated checksum.
|
|
|
|
2\. **Real-time change notification**, which is typically implemented within or as an extension to the kernel of the operating system that will flag when a file is accessed or modified.
