According to FindLaw UK, the major threats to e-commerce can be grouped into two categories, malicious and accidental threats. Some malicious threats include hackers attempting to penetrate a system and steal sensitive data, burglars stealing a laptop that has sensitive data on it and impostors posing as legitimate users and then copying website information. Another threat involves attackers breaching an e-commerce website to steal payment card information.
According to Dell SecureWorks, e-commerce security threats vary from intellectual property theft and business disruption to brand and image damage. Hackers attempt to breach e-commerce systems and networks to steal proprietary information on products and manufacturing processes. They then sell this information to cyber criminals, governments and competitors, or they use the information directly. The core of direct e-commerce threats affects the servers, which might suffer malicious code attacks where malicious programming code is introduced into the server in order to gain access to the system resources.
Examples of malicious code attacks include viruses, worms, Trojan horses and logic bombs. There are several ways to secure sites and transactions, such as through crypto building blocks that include encryption using symmetric and asymmetric-based key systems. Key management is crucial, and sometimes simpler can be better.
