# FAQ: What Is Set In Network Security?

Secure Electronic Transaction or SET is a system that ensures the security and integrity of electronic transactions done using credit cards in a scenario. It uses different encryption and hashing techniques to secure payments over the internet done through credit cards.

## What is set in computer network security?

Secure electronic transaction (SET) was an early communications protocol used by e-commerce websites to secure electronic debit and credit card payments. Secure electronic transaction was used to facilitate the secure transmission of consumer card information via electronic portals on the internet.

## What is set in networking?

Secure Electronic Transaction (SET) is a communications protocol standard for securing credit card transactions over networks, specifically, the Internet.

## What is the SSL and set?

SSL is a protocol for general purpose secure message exchange. SET protocol is a complex and more secure protocol. SET protocol was jointly developed by MasterCard and visa with the goal of securing web browsers for bank card transaction.

## Who are set participants?

SET involves interaction among credit card holders, merchants, issuing banks, payment processing organizations, and public-key certificate authorities. SET is a complex specification defined in three “books” issued in May 1997, and running to nearly 1,000 pages.

## What is set with example?

A set is a collection of elements or numbers or objects, represented within the curly brackets { }. For example: {1,2,3,4} is a set of numbers.

## What is set in Computer?

In computer science, a set is an abstract data type that can store unique values, without any particular order. It is a computer implementation of the mathematical concept of a finite set. Other variants, called dynamic or mutable sets, allow also the insertion and deletion of elements from the set.

## What is in a set?

In mathematics, a set is a collection of elements. The elements that make up a set can be any kind of mathematical objects: numbers, symbols, points in space, lines, other geometrical shapes, variables, or even other sets. Two sets are equal if and only if they have precisely the same elements.

## What is set and its types?

In Mathematics, sets are defined as the collection of objects whose elements are fixed and can not be changed. The Empty set, finite set, equivalent set, subset, universal set, superset, infinite set are some types of set. Each type of set has its own importance during calculations.

## Why do we use sets?

The purpose of sets is to house a collection of related objects. They are important everywhere in mathematics because every field of mathematics uses or refers to sets in some way. They are important for building more complex mathematical structure.

## What are set protocols?

Secure Electronic Transaction or SET is a system that ensures the security and integrity of electronic transactions done using credit cards in a scenario. SET is not some system that enables payment but it is a security protocol applied to those payments.

## What is HTTPS port?

HTTPS (Hypertext Transfer Protocol Secure) is a secured HTTP version where all traffic is bind with strong encryption that passes through 443. This port is also connected with TCP protocol and creates a secure connection between the webpages and browser.

## Is HTTPS TLS or SSL?

In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS) or, formerly, Secure Sockets Layer (SSL). The protocol is therefore also referred to as HTTP over TLS, or HTTP over SSL.

Secure Electronic Transaction works as follows:

• Step 1: Customer Open an Account.
• Step 2: Customer Receive a Certificate.
• Step 3: Merchant Receives a Certificate.
• Step 4: Customer Place an Order.
• Step 5: Merchant is Verified.
• Step 6: The Order and Payment Details Are Sent.
• Step 7: Merchant Requests Payment Authorization.

## Who is merchant in set architecture?

A number of participants are involved in the SET process: Cardholder/customer: The authorized holder of the payment card (Visa or Mastercard) E-commerce merchant: The seller. Card issuer: A financial organization (e.g., bank) that issues the payment card.

## What is called virtual terminal?

A virtual terminal is a software application (often a web application) for merchants which allows them to accept payment with a payment card, specifically a credit card, without requiring the physical presence of the card (“card not present transaction”).
