Introduction

The goal of this document is to create high level guideline for secure coding practices. The goal is to keep the overall size of the document condensed and easy to digest. Individuals seeking addition information on the specific areas should refer to the included links to learn more.

How To Use This Document

The information listed below are generally acceptable secure coding practices; however, it is recommend that organizations consider this a base template and update individual sections with secure coding recommendations specific to the organization's policies and risk tolerance.

Secure Coding Policy

Always maintain a secure coding policy. List down the activities that are related to maintenance of secure coding standards (would these standards be technology specific or technology agnostic), feedback of code review output to training, input data validation, output data validation etc

Why should you be having a secure coding policy? It helps in maintaining consistency across organisation and helps in vertical and horizontal scaling of usage of standards for web development projects.
