Site Security Planning

Nonrepudiation

There will always be customers who try to repudiate actions they have taken, such as claiming they did not make an online purchase. To discourage nonrepudiation, provide not only strong authentication and authorization for your site, but sufficient auditing for it as well. Without these measures, in combination with a strong liaison with law enforcement authorities, those who want to engage in nonrepudiation of business transactions will have ample opportunity.
