The internet has become a small trading universal market where several transactions take place on credit and debit cards. Sensitive data is not only transferred but also stored online. In the event such sensitive information falls into the hands of cyber criminals, this could result into serious financial repercussions both to traders as well as consumers. Payment Card Industry(PCI) compliance is a security checklist that aims to protect financial data and to help distinguish reliable enterprises from those that only have the aim of scheming money out of people’s pockets. Some of the ways and measures to securing website applications and databases are discussed below;


  1. Develop and Maintain Systems and Applications That are Secure

This one is all about putting into place control measures that minimize the existence of security vulnerabilities both in systems as well as software. It particularly gives the necessary requirements for software patching, attack protection, identification of vulnerability, change controls and secure software development. The reason as to why so much emphasis is put on web applications is because this is the entry point for cyber criminals to access backend databases with credit card data. The implementation of secure coding practices and open web application project can extensively help to reduce vulnerabilities in new web software.

  1. Protect Web Applications and Databases Against Known Attacks

Vulnerabilities and risks will be reduced when all web applications and databases are reviewed against common vulnerabilities. This is always done by a security specialist. The installation of web application firewalls help to block attacks from getting to credit card data.

  1. Track and Monitor all Access to Network Resources and Cardholder Data

This one aims at putting across an audit log of all access to network resources and card holder data. The performance and storage of databases requires that an audit trail that logs individual access to cardholder data be established.

The protection of databases saves organisations lots of damages. For instance, leaving web applications and databases exposed to the cyber criminal community might even lead to law suits. Preventive measures will do good to businesses and their customers as well.
