Overview

Days 29-42 of the 90 Days of Cybersecurity challenge focus on Python programming. Python is the most popular programming language in cybersecurity, used for automation, security tool development, data analysis, and exploit development.
While learning Python fundamentals, keep cybersecurity applications in mind. Think about how you can use Python to automate security tasks, parse log files, interact with APIs, and build security tools.

Essential Python Skills for Cybersecurity

Focus on these Python concepts that are critical for security work:

Core Programming

  • Data Structures: Lists, dictionaries, sets, tuples
  • String Manipulation: Parsing, regex, encoding/decoding
  • File Operations: Reading logs, parsing configurations
  • Error Handling: Try/except blocks for robust scripts

Security-Focused Libraries

  • Networking: socket, requests, scapy
  • System Interaction: os, sys, subprocess
  • Data Processing: json, csv, re (regex)
  • Cryptography: hashlib, cryptography, pycrypto

Practical Applications

  • Port Scanners: Network reconnaissance tools
  • Log Parsers: Analyzing security logs
  • API Interaction: Working with security APIs
  • Automation Scripts: Repetitive security tasks
  • Data Analysis: Processing security data

Study Tips

Practice Daily: Consistency is key. Write Python code every day, even if it’s just a small script.Build Security Tools: Don’t just do tutorials - build practical security tools like:
  • Simple port scanner
  • Password strength checker
  • Log file analyzer
  • Network packet sniffer
  • Basic vulnerability scanner
Read Other People’s Code: Study open-source security tools written in Python to learn best practices and common patterns.

Next Steps

After completing the Python section (Days 29-42), you’ll move on to Traffic Analysis (Days 43-56), where you’ll use tools like Wireshark and potentially write Python scripts to analyze network traffic.
