Electronic commerce (E-Commerce or EC) is an emerging concept that describes the process of buying and selling or exchanging of products, services, and information via computer networks including the Internet. It is the use of the Internet and the Web to transact business. Doing business online, typically via the Web. It is also called "e-business," "e-tailing" and "I-commerce." Although in most cases e-commerce and e-business are synonymous, e-commerce implies that goods and services can be purchased online, whereas e-business might be used as more of an umbrella term for a total presence on the Web, which would naturally include e-commerce (shopping) component.

E-commerce may also refer to electronic data interchange (EDI), in which one company's computer queries and transmits purchase orders to another company's computer.


E-Business is a revolution that is transforming companies round the world, and it is impacting all the industries. E-business is much more than online purchase and implementation of computer applications by the IT departments; or putting up a company website.

E-business affects the whole business and the value chains in which it operates. It enables a much more integrated level of collaboration between the different components of a value chain than ever before. Adopting e-Business also allows companies to reduce costs and improve customer response time. Organizations that transform their business practices stand to benefit immensely from innumerable new possibilities brought about by technology.

Although it's early days for e-Business in India, we believe there are greater opportunities over the long term for India and Indian businesses. There is urgent need to usher in farsighted policies & practices to become a major economic force in the emerging world of E-Business.

E-business includes

E-business is not just about selling over the Internet. It's a 'catch-all' term for any business done electronically. Amongst other things, it can include:

  • Computers and computer networks, sometimes called IT (Information Technology) or ICT (Information and Communication Technology)
  • Communicating by email
  • Running a website
  • Using the Internet to market your business or service
  • Using databases for contact management, stock control, or to communicate with  suppliers
  • Using business software.

Electronic banking

It is an umbrella term for the process by which a customer may perform banking transactions electronically without visiting a brick-and-mortar institution. The following terms all refer to one form or another of electronic banking: personal computer (PC) banking, Internet banking, virtual banking, online banking, home banking, remote electronic banking, and phone banking. PC banking and Internet or online banking are the most frequently used designations. It should be noted, however, that the terms used to describe the various types of electronic banking are often used interchangeably.

PC banking is a form of online banking that enables customers to execute bank transactions from a PC via a modem. In most PC banking ventures, the bank offers the customer a proprietary financial software program that allows the customer to perform financial transactions from his or her home computer. The customer then dials into the bank with his or her modem, downloads data, and runs the programs that are resident on the customer's computer. Currently, many banks offer PC banking systems that allow customers to obtain account balances and credit card statements, pay bills, and transfer funds between accounts.

Internet banking, sometimes called online banking, is an outgrowth of PC banking. Internet banking uses the Internet as the delivery channel by which to conduct banking activity, for example, transferring funds, paying bills, viewing checking and savings account balances, paying mortgages, and purchasing financial instruments and certificates of deposit. An Internet banking customer accesses his or her accounts from a browser- software that runs Internet banking programs resident on the bank's World Wide Web server, not on the user's PC. NetBanker defines a " true Internet bank" as one that provides account balances and some transactional capabilities to retail customers over the World Wide Web. Internet banks are also known as virtual, cyber, net, interactive, or web banks.

To date, more banks have established an advertising presence on the Internet- primarily in the form of informational or interactive web sites-than have created transactional web sites. However, a number of Banks that do not yet offer transactional Internet banking services have indicated on their web sites that they will offer such banking activities in the future.

Internet banks generally have lower operational and transactional costs than do traditional brick-and-mortar banks, they are often able to offer low-cost checking and high-yield Certificates of deposit. Internet banking is not limited to a physical site; some Internet banks exist without physical branches, for example, Telebank (Arlington, Virginia) and Banknet (UK). Further, in some cases, web banks are not restricted to conducting transactions within national borders and have the ability to make transactions involving large amounts of assets instantaneously. According to industry analysts, electronic banking provides a variety of attractive possibilities for remote account access, including:

  • Availability of inquiry and transaction services around the clock;
  • worldwide connectivity;
  • Easy access to transaction data, both recent and historical; and
  • "Direct customer control of international movement of funds without intermediation of financial institutions in customer's jurisdiction."

Opening an Account

There are several ways to open and fund an electronic banking account in the United States. Customers who have existing accounts at brick-and-mortar banks and want to begin using electronic banking services may simply ask their institution for the software needed for PC banking or obtain a password for Internet banking. Either approach requires minimal paperwork. Once they have joined the system, customers have electronic access to all of their accounts at the bank. New customers can establish an account either by completing a PC banking application form and mailing it to an institution offering such a service or by accessing a bank's web site and applying online for Internet banking. In either instance, the customer can fund the new online account with a check, wire transfer, or other form of remittance. No physical interface between the customer and the institution is required.

Definition of E-Banking

E-banking is defined as the automated delivery of new and traditional banking products and services directly to customers through electronic, interactive communication channels. E-banking includes the systems that enable financial institution customers, individuals or businesses, to access accounts, transact business, or obtain information on financial products and services through a public or private network, including the Internet.

Customers access e-banking services using an intelligent electronic device, such as a personal computer (PC), personal digital assistant (PDA), automated teller machine (ATM), kiosk, or Touch Tone telephone. While the risks and controls are similar for the various e-banking access channels, this booklet focuses specifically on Internet-based services due to the Internet's widely accessible public network. Accordingly, this booklet begins with a discussion of the two primary types of Internet websites: informational and transactional.

Informational Websites

Informational websites provide customers access to general information about the financial institution and its products or services. Risk issues examiners should consider when reviewing informational websites include:

Potential liability and consumer violations for inaccurate or incomplete information about products, services, and pricing presented on the website;

Potential access to confidential financial institution or customer information if the website is not properly isolated from the financial institution's internal network;

Potential liability for spreading viruses and other malicious code to computers communicating with the institution's website; and

Negative public perception if the institution's on-line services are disrupted or if its website is defaced or otherwise presents inappropriate or offensive material.

Transactional Websites

Transactional websites provide customers with the ability to conduct transactions through the financial institution's website by initiating banking transactions or buying products and services. Banking transactions can range from something as basic as a retail account balance inquiry to a large business-to-business funds transfer. E-banking services, like those delivered through other delivery channels, are typically classified based on the type of customer they support. The following table lists some of the common retail and wholesale e-banking services offered by financial institutions.

Table 1: Common E-Banking Services

Retail Services

Wholesale Services

Bill payment and presentment

Cash management

New account opening

Small business loan applications, approvals, or advances

Consumer wire transfers


Investment/Brokerage services

Commercial wire transfers

Business-to-business payments

Account aggregation

Employee benefits/pension administration

Since transactional websites typically enable the electronic exchange of confidential customer information and the transfer of funds, services provided through these websites expose a financial institution to higher risk than basic informational websites. Wholesale e-banking systems typically expose financial institutions to the highest risk per transaction, since commercial transactions usually involve larger dollar amounts. In addition to the risk issues associated with informational websites, examiners reviewing transactional e-banking services should consider the following issues:

Security controls for safeguarding customer information;

Authentication processes necessary to initially verify the identity of new customers and authenticate existing customers who access e-banking services;

Liability for unauthorized transactions;

Losses from fraud if the institution fails to verify the identity of individuals or businesses applying for new accounts or credit on-line;

Possible violations of laws or regulations pertaining to consumer privacy, anti-money laundering, anti-terrorism, or the content, timing, or delivery of required consumer disclosures; and

Negative public perception, customer dissatisfaction, and potential liability resulting from failure to process third-party payments as directed or within specified time frames, lack of availability of on-line services, or unauthorized access to confidential customer information during transmission or storage.

E-Banking Components

E-banking systems can vary significantly in their configuration depending on a number of factors. Financial institutions should choose their e-banking system configuration, including outsourcing relationships, based on four factors:

Strategic objectives for e-banking

Scope, scale, and complexity of equipment, systems, and activities;

Technology expertise; and

Security and internal control requirements.

Financial institutions may choose to support their e-banking services internally. Alternatively, financial institutions can outsource any aspect of their e-banking systems to third parties. The following entities could provide or host (i.e., allow applications to reside on their servers) e-banking-related services for financial institutions:

Another financial institution,

Internet service provider,

Internet banking software vendor or processor,

Core banking vendor or processor,

Managed security service provider,

Bill payment provider,

Credit bureau, and

Credit scoring company.

E-banking systems rely on a number of common components or processes. The following list includes many of the potential components and processes seen in a typical institution:

Website design and hosting,

Firewall configuration and management,

Intrusion detection system or IDS (network and host-based),

Network administration,

Security management,

Internet banking server,

E-commerce applications (e.g., bill payment, lending, brokerage),

Internal network servers,

Core processing system,

Programming support, and

Automated decision support systems.

These components work together to deliver e-banking services. Each component represents a control point to consider.

Through a combination of internal and outsourced solutions, management has many alternatives when determining the overall system configuration for the various components of an e-banking system. However, for the sake of simplicity, this booklet presents only two basic variations. First, one or more technology service providers can host the e-banking application and numerous network components as illustrated in the following diagram. In this configuration, the institution's service provider hosts the institution's website, Internet banking server, firewall, and intrusion detection system. While the institution does not have to manage the daily administration of these component systems, its management and board remain responsible for the content, performance, and security of the e-banking system.

Second, the institution can host all or a large portion of its e-banking systems internally. A typical configuration for in-house hosted, e-banking services is illustrated below. In this case, a provider is not between the Internet access and the financial institution's core processing system. Thus, the institution has day-to-day responsibility for system administration.

E-Banking Support Services

In addition to traditional banking products and services, financial institutions can provide a variety of services that have been designed or adapted to support e-commerce. Management should understand these services and the risks they pose to the institution. This section discusses some of the most common support services: web linking, account aggregation, electronic authentication, website hosting, payments for e-commerce, and wireless banking activities.

Web Linking

A large number of financial institutions maintain sites on the World Wide Web. Some websites are strictly informational, while others also offer customers the ability to perform financial transactions, such as paying bills or transferring funds between accounts.

Virtually every website contains "weblinks." A weblink is a word, phrase, or image on a webpage that contains coding that will transport the viewer to a different part of the website or a completely different website by just clicking the mouse. While weblinks are a convenient and accepted tool in website design, their use can present certain risks. Generally, the primary risk posed by weblinking is that viewers can become confused about whose website they are viewing and who is responsible for the information, products, and services available through that website. There are a variety of risk management techniques institutions should consider using to mitigate these risks. These risk management techniques are for those institutions that develop and maintain their own websites, as well as institutions that use third-party service providers for this function. The agencies have issued guidance on weblinking that provides details on risks and risk management techniques financial institutions should consider.

Account Aggregation

Account aggregation is a service that gathers information from many websites, presents that information to the customer in a consolidated format, and, in some cases, may allow the customer to initiate activity on the aggregated accounts. The information gathered or aggregated can range from publicly available information to personal account information (e.g., credit card, brokerage, and banking data). Aggregation services can improve customer convenience by avoiding multiple log-ins and providing access to tools that help customers analyze and manage their various account portfolios. Some aggregators use the customer-provided user IDs and passwords to sign in as the customer. Once the customer's account is accessed, the aggregator copies the personal account information from the website for representation on the aggregator's site (i.e., "screen scraping"). Other aggregators use direct data-feed arrangements with website operators or other firms to obtain the customer's information. Generally, direct data feeds are thought to provide greater legal protection to the aggregator than does screen scraping.

Financial institutions are involved in account aggregation both as aggregators and as aggregation targets. Risk management issues examiners should consider when reviewing aggregation services include:

Protection of customer passwords and user IDs - both those used to access the institution's aggregation services and those the aggregator uses to retrieve customer information from aggregated third parties - to assure the confidentiality of customer information and to prevent unauthorized activity,

Disclosure of potential customer liability if customers share their authentication information (i.e., IDs and passwords) with third parties, and

Assurance of the accuracy and completeness of information retrieved from the aggregated parties' sites, including required disclosures

Electronic Authentication

Verifying the identities of customers and authorizing e-banking activities are integral parts of e-banking financial services. Since traditional paper-based and in-person identity authentication methods reduce the speed and efficiency of electronic transactions, financial institutions have adopted alternative authentication methods, including:

Passwords and personal identification numbers (PINs),

Digital certificates using a public key infrastructure (PKI),

Microchip-based devices such as smart cards or other types of tokens,

Database comparisons (e.g., fraud-screening applications), and

Biometric identifiers.

The authentication methods listed above vary in the level of security and reliability they provide and in the cost and complexity of their underlying infrastructures. As such, the choice of which technique(s) to use should be commensurate with the risks in the products and services for which they control access. Additional information on customer authentication techniques can be found in this booklet under the heading "Authenticating E-Banking Customers."

The Electronic Signatures in Global and National Commerce (E-Sign) Act establishes some uniform federal rules concerning the legal status of electronic signatures and records in commercial and consumer transactions so as to provide more legal certainty and promote the growth of electronic commerce. The development of secure digital signatures continues to evolve with some financial institutions either acting as the certification authority for digital signatures or providing repository services for digital certificates.

Website Hosting

Some financial institutions host websites for both themselves as well as for other businesses. Financial institutions that host a business customer's website usually store, or arrange for the storage of, the electronic files that make up the website. These files are stored on one or more servers that may be located on the hosting financial institution's premises. Website hosting services require strong skills in networking, security, and programming. The technology and software change rapidly. Institutions developing websites should monitor the need to adopt new interoperability standards and protocols such as Extensible Mark-Up Language (XML) to facilitate data exchange among the diverse population of Internet users.

Risk issues examiners should consider when reviewing website hosting services include damage to reputation, loss of customers, or potential liability resulting from:

Downtime (i.e., times when website is not available) or inability to meet service levels specified in the contract,

Inaccurate website content (e.g., products, pricing) resulting from actions of the institution's staff or unauthorized changes by third parties (e.g., hackers),

Unauthorized disclosure of confidential information stemming from security breaches, and

Damage to computer systems of website visitors due to malicious code (e.g., virus, worm, active content) spread through institution-hosted sites.

Payments for E-Commerce

Many businesses accept various forms of electronic payments for their products and services. Financial institutions play an important role in electronic payment systems by creating and distributing a variety of electronic payment instruments, accepting a similar variety of instruments, processing those payments, and participating in clearing and settlement systems. However, increasingly, financial institutions are competing with third parties to provide support services for e-commerce payment systems. Among the electronic payments mechanisms that financial institutions provide for e-commerce are automated clearing house (ACH) debits and credits through the Internet, electronic bill payment and presentment, electronic checks, e-mail money, and electronic credit card payments..

Most financial institutions permit intrabank transfers between a customer's accounts as part of their basic transactional e-banking services. However, third-party transfers - with their heightened risk for fraud - often require additional security safeguards in the form of additional authentication and payment confirmation.

Bill Payment and Presentment

Bill payment services permit customers to electronically instruct their financial institution to transfer funds to a business's account at some future specified date. Customers can make payments on a one-time or recurring basis, with fees typically assessed as a "per item" or monthly charge. In response to the customer's electronic payment instructions, the financial institution (or its bill payment provider) generates an electronic transaction - usually an automated clearinghouse (ACH) credit - or mails a paper check to the business on the customer's behalf. To allow for the possibility of a paper-based transfer, financial institutions typically advise customers to make payments effective 3-7 days before the bill's due date.

Internet-based cash management is the commercial version of retail bill payment. Business customers use the system to initiate third-party payments or to transfer money between company accounts. Cash management services also include minimum balance maintenance, recurring transfers between accounts and on-line account reconciliation. Businesses typically require stronger controls, including the ability to administer security and transaction controls among several users within the business.

Financial institutions that do not provide bill payment services, but may direct customers to select from several unaffiliated bill payment providers.
Caution customers regarding security and privacy issues through the use of on-line disclosures or, more conservatively, e-banking agreements.

Financial institutions that rely on a third-party bill payment provider including Internet banking providers that subcontract to third parties.
* Set dollar and volume thresholds and review bill payment transactions for suspicious activity
* Gain independent audit assurance over the bill payment provider's processing controls
* Restrict employees' administrative access to ensure that the internal controls limiting their capabilities to originate, modify, or delete bill payment transactions are at least as strong as those applicable to the underlying retail payment system ultimately transmitting the transaction
* Restrict by vendor contract and identify the use of any subcontractors associated with the bill payment application to ensure adequate oversight of underlying bill payment system performance and availability
* Evaluate the adequacy of authentication methods given the higher risk associated with funds transfer capabilities rather than with basic account access
* Consider the additional guidance contained in the IT Handbook's "Information Security," "Retail Payment Systems," and "Outsourcing Technology Services" booklets.

Financial institutions that use third-party software to host a bill payment application internally.
* Determine the extent of any independent assessments or certification of the security of application source code.
* Ensure software is adequately tested prior to installation on the live system.
* Ensure vendor access for software maintenance is controlled and monitored.

Financial institutions that develop, maintain, and host their own bill payment system
Consider additional guidance in the IT Handbook's "Development and Acquisition Booklet."

Financial institutions can offer bill payment as a stand-alone service or in combination with bill presentment. Bill presentment arrangements permit a business to submit a customer's bill in electronic form to the customer's financial institution. Customers can view their bills by clicking on links on their account's e-banking screen or menu. After viewing a bill, the customer can initiate bill payment instructions or elect to pay the bill through a different payment channel.

In addition, some businesses have begun offering electronic bill presentment directly from their own websites rather than through links on the e-banking screens of a financial institution. Under such arrangements, customers can log on to the business's website to view their periodic bills. Then, if so desired, they can electronically authorize the business to "take" the payment from their account. The payment then occurs as an ACH debit originated by the business's financial institution as compared to the ACH credit originated by the customer's financial institution in the bill payment scenario described above. Institutions should ensure proper approval of businesses allowed to use ACH payment technology to initiate payments from customer accounts.

Cash management applications would include the same control considerations described above, but the institution should consider additional controls because of the higher risk associated with commercial transactions. The adequacy of authentication methods becomes a higher priority and requires greater assurance due to the larger average dollar size of transactions. Institutions should also establish additional controls to ensure binding agreements - consistent with any existing ACH or wire transfer agreements - exist with commercial customers. Additionally, cash management systems should provide adequate security administration capabilities to enable the business owners to restrict access rights and dollar limits associated with multiple-user access to their accounts.

Person-to-Person Payments

Electronic person-to-person payments, also known as e-mail money, permit consumers to send "money" to any person or business with an e-mail address. Under this scenario, a consumer electronically instructs the person-to-person payment service to transfer funds to another individual. The payment service then sends an e-mail notifying the individual that the funds are available and informs him or her of the methods available to access the funds including requesting a check, transferring the funds to an account at an insured financial institution, or retransmitting the funds to someone else. Person-to-person payments are typically funded by credit card charges or by an ACH transfer from the consumer's account at a financial institution. Since neither the payee nor the payer in the transaction has to have an account with the payment service, such services may be offered by an insured financial institution, but are frequently offered by other businesses as well.

Some of the risk issues examiners should consider when reviewing bill payment, presentment, and e-mail money services include:

Potential liability for late payments due to service disruptions,

Liability for bill payment instructions originating from someone other than the deposit account holder,

Losses from person-to-person payments funded by transfers from credit cards or deposit accounts over which the payee does not have signature authority,

Losses from employee misappropriation of funds held pending access instructions from the payer, and

Potential liability directing payment availability information to the wrong e-mail or for releasing funds in response to e-mail from someone other than the intended payee.

Wireless E-Banking

Wireless banking is a delivery channel that can extend the reach and enhance the convenience of Internet banking products and services. Wireless banking occurs when customers access a financial institution's network(s) using cellular phones, pagers, and personal digital assistants (or similar devices) through telecommunication companies' wireless networks. Wireless banking services in the United States typically supplement a financial institution's e-banking products and services.

Wireless devices have limitations that increase the security risks of wireless-based transactions and that may adversely affect customer acceptance rates. Device limitations include reduced processing speeds, limited battery life, smaller screen sizes, different data entry formats, and limited capabilities to transfer stored records. These limitations combine to make the most recognized Internet language, Hypertext Markup Language (HTML), ineffective for delivering content to wireless devices. Wireless Markup Language (WML) has emerged as one of a few common language standards for developing wireless device content. Wireless Application Protocol (WAP) has emerged as a data transmission standard to deliver WML content.

Manufacturers of wireless devices are working to improve device usability and to take advantage of enhanced "third-generation" (3G) services. Device improvements are anticipated to include bigger screens, color displays, voice recognition applications, location identification technology (e.g., Federal Communications Commission (FCC) Enhanced 911), and increased battery capacity. These improvements are geared towards increasing customer acceptance and usage. Increased communication speeds and improvements in devices during the next few years should lead to continued increases in wireless subscriptions.

As institutions begin to offer wireless banking services to customers, they should consider the risks and necessary risk management controls to address security, authentication, and compliance issues. Some of the unique risk factors associated with wireless banking that may increase a financial institution's strategic, transaction, reputation, and compliance risks


e-banking creates issues for banks and regulators alike. For our part we will continue our work, both national and international, to identify and remove any unnecessary barriers to e-banking. For their part, banks should:

Have a clear and widely disseminated strategy that is driven from the top and takes into account the effects of e-banking, together with an effective process for measuring performance against it.Take into account the effect that e-provision will have upon their business risk exposures and manage these accordingly.

Undertake market research, adopt systems with adequate capacity and scalability, undertake proportional advertising campaigns and ensure that they have adequate staff coverage and a suitable business continuity plan.Ensure they have adequate management information in a clear and comprehensible format.

Take a strategic and proactive approach to information security, maintaining adequate staff expertise, building in best practice controls and testing and updating these as the market develops. Make active use of system based security management and monitoring tools.Ensure that crisis management processes are able to cope with Internet related incidents.
