Introduction

 

Our project aims at providing a semi-dynamic template of a fully fledged highly responsive webpage for small scale organizational usage. With improved security considerations and better organization this project integrates google sheets services as a database for a website. Google sheets being easy to deploy and use makes content updation easier and a lot more user friendly. Several other functionalities like Google scripting engine along with google forms can be very easily integrated with google sheets thus, can be used for real time and secure updation of website content. Furthermore, it separates developer and non-developer roles thus defining user privileges.

 

Several formatting and scripting languages like HTML, JQuery, PHP and CSS were used for complete frontend and backend development. Necessary security measures has been incorporated to provide introductory and necessary protection against various unwanted attacks like XSS.
Additionally, important measures were taken for making website responsive on various viewports, and platforms to provide best user experience.

 

Purpose Behind

 

There were two main objectives for our design:
  • Security Consideration
  • Separation of developer and non-developer parts

 

  1. Security Considerations:

 

Heavy websites are mostly build on packages like wordpress, drupal etc. These rely heavily on local  dynamic databases like MySQL, MongoDB etc. During a successful DDOS attack, large chunks of firewall logs gets collected in server, thus there’s no space left for dynamic services to store their data and they  usually terminate, causing website to fail.
Apart from this, using local database also makes a website prone to attacks like, SQL Injection, Privilege abuse, Database protocol vulnerabilities etc.

 

  2. Separation of developer and non-developer roles

 

Websites requires both developer roles, like maintaining, designing and debugging the site and non-developer role like content preparation and regular content updation.
Storing both the segments in a single file might lead to unwanted distribution of privileges, by mistake changes in the code etc.  This also increases website maintenance costs.

Proposed design
Front End Overview
Complete front end design can be divided into 5 different sectors,namely
  • NAVIGATIONAL BAR
    • used for linking different pages together with the main page.
    • Ensures easy navigation for users.
  • HEADER
    • Contains title of the page along with organization logo.
    • Contains About us link.

  • CAROUSAL
    • For impressive display of work done by the organization.
    • Should be mobile compatible.
  • EVENTS
    • For display of recent events organized by the organization, along with their link and description.
  • ABOUT US
    • For team introduction, along with initial motto of the organization.

Backend Overview

 

Backend sections integrates database, google sheets in our case with the main website template. It’s main purpose is to:
  • FETCH DATA
    • In our model, data is fetched from google sheets in CSV format.
  • VERIFY DATA
    • After extracting data, it needs to be checked for removal of malicious code snippets to improve code reliability and security. Thus, avoiding XSS attacks.
  • PUBLISH CONTENT
    • In our template data is published by php’s ‘ECHO’ command embedded in the their respective locations.
