Exam Certification Objectives & Outcome Statements

  • Control Structures and Iteration
    The candidate will be able to create and analyze simple control structures, including conditionals (if/else/elif) and for/while loops using Python.
  • Creation of Executables
    The candidate will have a basic understanding of creating a Python executable for Windows clients with a focus on penetration testing. This includes an understanding of backdoor functionality, the conversion of a Python program to an executable file, and using Python to create an executable that will evade most modern anti-virus signatures.
  • Data Analysis with Python
    The candidate will demonstrate the ability to use Python for various data analysis techniques including parsing binary data with the struct module, common file formats, log analysis and statistics with, counters and sets, long tail and short-tail analysis.
  • Data Structures
    The candidate will be able to create and manipulate variable types and data structures, including bytes, byte arrays, byte encoded unicode characters using UTF-8 and Latin-1, integers, Python 3 strings, sets and sequential data structures, including dictionaries, lists, and tuples.
  • Database Interaction
    The candidate will understand how to create a Python program to query databases using SQL libraries.
  • Exception Handling
    The candidate will have a basic understanding of Python exception handling capabilities, and how to build these into a program.
  • Functions, Classes and Objects
    The candidate will be able to demonstrate an understanding of Python functions, classes, and object oriented programming.
  • Network Interfaces
    The candidate will be able to implement TCP and UDP network based communications using Pythons socket module.
  • Packet Analysis with Python
    The candidate will understand how to use extended functionality of Python and Scapy to create, read, analyze, and manipulate captured network traffic.
  • Python Basics
    The candidate will be able to implement the more fundamental elements of Python, including creating, debugging and executing a program, and user/file input and output.
  • Regular Expressions
    The candidate will have a basic understanding of regular expressions, and how to implement them in searches with Python.
  • Website Interaction
    The candidate will understand how to use Python as a "browser" to interact with URLs and websites, handle cookies, and manipulate or capture traffic.

Other Resources

  • Training is available in a variety of modalities including live conference training and OnDemand
  • Practical work experience can help ensure that you have mastered the skills necessary for certification
  • College level courses or self paced study through another program or materials may meet the needs for mastery.

Practice Tests

  • These tests are a simulation of the real exam allowing you to become familiar with the test engine and style of questions.
  • Practice exams are a gauge to determine if your preparation methods are sufficient.
  • The practice bank questions are limited so you may encounter the same question on practice tests when multiple practice tests are purchased.
  • Practice exams never include actual exam questions.
  • Purchase a GPYC practice test here.
  • GIAC recommends leveraging additional study methods for test preparation.
