E-commerce and the security problems of e-business

Meaning of e-commerce

E-commerce (electronic commerce) is the buying and selling of goods and services, and the transfer of money and data, over electronic networks, chiefly the internet. E-business is wider: it covers all business activities conducted electronically: not only selling but also procurement, supply-chain management, customer service, internal communication and dealings with government.

E-commerce takes several forms:

• B2B (business to business), such as a manufacturer ordering components online from suppliers;
• B2C (business to consumer), such as online retail and food delivery;
• C2C (consumer to consumer), such as resale marketplaces;
• C2B dealings, in which the consumer starts the exchange with the business: placing an order, raising an enquiry or making a complaint online; the term is also used for individuals, such as freelancers, selling their services to firms;
• beyond the study text's classification, B2G dealings, such as firms bidding in online government procurement.

Its benefits include wider reach, 24-hour availability, lower costs, quick transactions and easy comparison for customers.

Security problems related to e-business

Because the parties deal at a distance and often never meet, it is harder to know who is on the other side of a transaction and whether data and money are safe in transit, so security is a central concern of e-business.

1. Payment and credit-card fraud. Stolen card details, fake payment requests, phishing links and unauthorised digital-wallet transactions.
2. Data theft and breach of privacy. Hackers may steal customers' personal and financial data from a firm's servers; firms may also misuse customer data.
3. Hacking and unauthorised access. Intruders may alter prices, place false orders or deface websites.
4. Malware, viruses and ransomware. Malicious software can corrupt data, disrupt systems or lock files until a ransom is paid.
5. Denial-of-service attacks. Flooding a website with traffic makes it unavailable to genuine customers.
6. Identity and impersonation risks. Fake websites and sellers impersonating genuine brands cheat customers.
7. Authentication and non-repudiation problems. It may be hard to prove who sent a message or placed an order, and a party may deny a transaction.
8. Insider threats. Employees with access may leak or misuse data.
9. Disputes over the deal itself. A buyer may say an order was never placed, a seller that payment never came, or goods may arrive wrong or damaged; with no face-to-face record, such disputes are harder to settle.

Measures to deal with them

Encryption of data and secure (HTTPS) connections; digital signatures and certificates for authentication; two-factor authentication and one-time passwords for payments; firewalls, antivirus and regular security audits; secure payment gateways and cash-on-delivery or escrow arrangements; clear return and refund policies; data-protection practices and staff training; and prompt reporting of fraud to the bank and the police so that losses can be limited.

Example. An online grocery start-up adds one-time-password verification for payments, stores card data only with a certified payment gateway, and runs quarterly security audits after a phishing attack on its customers.

Conclusion

E-commerce offers great opportunities, but trust is its foundation. Firms that invest in security and fair practices protect both their customers and their own reputation.
