TRYHACKME’S ADVENT OF CYBER 2023 (Day 7)

 Day 7 - “‘Tis the season for log chopping!”

The primary objectives of this challenge were :

• Revisiting log files and their importance
• what is a proxy and breaking down the contents of a proxy log
• Building Linux command-line skills to parse log entries manually
• Analysing a proxy log based on typical use cases.

In this task we were given a proxylog and asked to asked certain questions, which required us to use some commands like cut, sort, uniq, grep, head, tail, base64

A proxy server is an intermediary between your computer or device and the internet. When you request information or access a web page, your device connects to the proxy server instead of connecting directly to the target server. The proxy server then forwards your request to the internet, receives the response, and sends it back to your device.

The cut command allows you to extract specific sections of lines from a file or input stream by "cutting" the line into columns based on a delimiter and selecting which columns to display.

Grep is a command in Linux that is used for searching text within files or input streams

Sort is a Linux command used to sort the lines of text files or input streams in ascending or descending order, while the uniq command allows you to filter out and display unique lines from a sorted file or input stream.

Here is the walkthrough of Day 7.
