Functions in Python
Here I discuss functions in Python through code and problem statements as practiced in the Course 7: Automate Cybersecurity Tasks with Python. This lab is done in the Jupyter notebook.
1. Basic Alert Function:
Calling the alert() function that was defined earlier, that is how the statements inside the function are printed as an output.
2. Repeating Alerts with a Loop:
Using for loop inside the function and then calling it, as long as the iteration remains, the same line will get printed as an output.
3. Reading a List of Usernames:
Using a for loop inside a function to go through all the elements of the username_list and then print them.
4. Combining Names into One Line:
Displaying the same list using the string concatenation using the + sign.
5. Sorting Login Attempts:
Use of the built-in sorted() function to print the elements of the list in an ascending order.

6. Finding the Worst-Case Number:
Use of the built-in max() function to print the maximum number of failed login attempts in a month.
7. Passing Info into Functions:
Calling a function with parameters and arguments.
8. Adding Baseline Averages:
Calculating an average of a user’s daily logins into a system.
9. Doing Math with return:
Using the return statement instead can also be efficient.
10. Triggering Conditional Alerts:
Creating an alert if number of logins from the same user is more than or equal to 3 because this demands an investigation.
So, this was all about the functions in Python. I will see you in the next lab where I explore and learn more about the Python programming language and how to implement this logic into day-to-day SOC analyst tasks.
