, , No Comments

The security in e-commerce is becoming more topical the ongoing success and
growth. However, Internet is an open communications network and anyone can exploit
its vulnerabilities for fraudulent gain. If the Internet is to succeed as a business and
communications tool, then the security is the most fundamental issue that needs to be
taken care of. The following are some of the security features that can be implemented
for success of e-commerce:

• Identification or Authenticator : The persons/entities with whom we are
communicating are really they arc.

• Confidentiality: The content of the message or transaction is kept
confidential. It should only be read and understood by the intended sender
and receiver.

• Integrity: The content of the message or transaction is not tampered
accidentally or deliberately.

• Non-Repudiation: The sender and receiver cannot deny sending and
receiving of the message or transaction respectively.

Access Control: Access to the protected information is only realized by the
intended person or entity

There are two levels for securing information over the Internet:

• The first level is issue of a Digital certificate. Digital certificates provide a
means of proving your identity in electronic transactions; much like a
driving license or a passport. With a Digital certificate, you can assure
friends, business associates, and online services that the electronic
information they receive from you is authentic.

• The second level is SSL (Secure Sockets Layer). SSL is a standard security
technology that helps in establishing an encrypted link between the server
and the client - typically a web server (e-commerce website) and a browser
(consumer side). SSL allows client/server apil1icationsto exchange sensitive
information such as credit card numbers and login credentials securely
preventing others from eavesdropping, tampering or forging the information.
