A Linux script that Automate log checking to identify attempted unauthorized logins to the server, identify the most egregious offenders, and add them to the server’s firewall

I am looking for a freelancer to develop a Linux script that will automate log checking on my server. The script should be written in Bash.

Functionality:
- The script should identify attempted unauthorized logins to the server.
- It should also identify the most egregious offenders.
- Finally, it should add the identified offenders to the server's firewall.

This is for a project. It is not a business solution. This needs to be completed by 11:59pm EST. Very important to my grade, lost all my data after dropping my computer

Preferred Method for Handling Offenders:
- The client did not specify their preferred method for handling identified offenders.

Desired Frequency for Log Checking and Offender Identification:
- The client did not specify their desired frequency for log checking and offender identification.

Ideal Skills and Experience:
- Strong knowledge and experience in Linux scripting, specifically with Bash.
- Understanding of server logs and log analysis.
- Familiarity with server firewalls and how to add IP addresses to them.

Please note that the client did not provide complete information regarding their preferred method for handling offenders and the desired frequency for log checking. These details can be discussed further with the client to ensure the project meets their specific requirements.
