eCommerce security refers to the principles which guide safe electronic transactions, allowing the buying and selling of goods and services through the Internet, but with protocols in place to provide safety for those involved. Successful business online depends on the customers’ trust that a company has eCommerce security basics in place.


One of the most obvious eCommerce security basics is privacy, which in this situation means not sharing information with unauthorized parties. When you shop online, your personal details or account information should not be accessible to anyone except the seller you have chosen to share it with. Any disclosure of that information by the merchant would be a breach of confidentiality. The business is responsible to provide at least the minimum in encryption, virus protection, and a firewall so that bank details and credit card information remain private.


A second concept which is crucial within secure eCommerce is the idea of integrity—that none of the information shared online by the customer will be altered in any way. This principle states that a secure transaction includes unchanged data—that the business is only using exactly what was entered into the Internet site by the buyer. Any tampering with information is breaking the confidence of the buyer in the security of the transaction and the integrity of the company in general.



For eCommerce to take place, both seller and buyer have to be who they say they are. A business cannot sell unless it’s real, the products are real, and the sale will go through as described online. The buyer must also provide proof of identification so that the merchant can feel secure about the sale. In eCommerce, fraudulent identification and authentication are possible, and many businesses hire an expert to make sure these kinds of eCommerce security basics are in place. Common solutions include technological solutions—customer logins and passwords or additional credit card PINs.


Repudiation is denial, and good business depends on both buyers and sellers following through on the part of the transaction which originated with them—not denying those actions. Since eCommerce happens in cyberspace, usually without any live video, it can feel less safe and sure. The legal principle of non-repudiation adds another level of security by confirming that the information which was sent between parties was indeed received and that a purchase or email or signature cannot be denied by the person who completed the transaction.  

Customers who don’t feel transactions are secure won’t buy. Hesitation on the part of the buyer will destroy eCommerce potential. Any breach will cost a business in lost revenues and consumer trust. These eCommerce security basics can guide any business owner regarding safe online transaction protocol.
