Abstract: The present paper describes a methodology that could be employed to establish the commonality of electronic practices in judicial proceedings. Two security practices are then examined: the practice of supporting strong encryption of transactions by banking servers and the practice of denial of service to |weak| clients. The empirical analysis proves that the former practice is customary, whereas the latter could be regarded as custom in statu nascendi or as the best practice. Finally, this paper makes a call to configure web servers so that they deny a service, if a web browser does not support strong encryption of transactions.
