Security
- Since the customer is usually required to enter personal details, the entire communication of 'Submit Order' page (i.e. customer - payment gateway) is often carried out through HTTPS protocol.
- To validate the request of the payment page result, signed request is often used - which is the result of the hash function in which the parameters of an application confirmed by a «secret word», known only to the merchant and payment gateway.
- To validate the request of the payment page result, sometimes IP of the requesting server has to be verified.
- There is a growing support by acquirers, issuers and subsequently by payment gateways for Virtual Payer Authentication (VPA), implemented as 3-D Secure protocol - branded as Verified by VISA, MasterCard SecureCode and J/Secure by JCB along with Card_Verification_Value, which adds additional layer of security for online payments. 3-D Secure promises to alleviate some of the problems facing online merchants, like the inherent distance between the seller and the buyer, and the inability of the first to easily confirm the identity of the second.
- Payment Gateway provider also follow PCI DSS, Payment Card Industry Data Security Standard PCI_DSS, which ensure safety of the cardholder's data

Famous quotes containing the word security:
“... most Southerners of my parents’ era were raised to feel that it wasn’t respectable to be rich. We felt that all patriotic Southerners had lost everything in defense of the South, and sufficient time hadn’t elapsed for respectable rebuilding of financial security in a war- impoverished region.”
—Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 1, ch. 1 (1962)
“It seems to me that our three basic needs, for food and security and love, are so mixed and mingled and entwined that we cannot straightly think of one without the others. So it happens that when I write of hunger, I am really writing about love and the hunger for it, and warmth and the love of it and the hunger for it ... and then the warmth and richness and fine reality of hunger satisfied ... and it is all one.”
—M.F.K. Fisher (b. 1908)
“To have in general but little feeling, seems to be the only security against feeling too much on any particular occasion.”
—George Eliot [Mary Ann (or Marian)
