Q.6 Explain the security measures implemented in online payment systems.

Solution :- 

• Online payment systems handle sensitive financial transactions, making security a top priority.

• Various measures are implemented to protect users from fraud, data breaches, and cyber threats.

1. Encryption

• What it does: Converts data into an unreadable format to prevent unauthorized access.

• Example: Secure Socket Layer (SSL) and Transport Layer Security (TLS) encrypt data during transmission.

2. Two-Factor Authentication (2FA)

• What it does: Adds an extra layer of security by requiring a second verification step.

• Example: OTP (One-Time Password) sent via SMS or email.

3. Secure Payment Gateways

• What it does: Acts as an intermediary between buyers, sellers, and banks, ensuring safe transactions.

• Example: PayPal, Razorpay, Stripe.

4. Tokenization

• What it does: Replaces sensitive card details with a unique token to prevent fraud.

• Example: Instead of storing actual card numbers, a random token is used for processing payments.

5. Fraud Detection Systems

• What it does: Monitors transactions for unusual patterns and flags suspicious activities.

• Example: AI-based fraud detection identifies abnormal spending behavior.

6. PCI DSS Compliance

• What it does: Ensures that payment systems follow global security standards.

• Example: Merchants must comply with PCI DSS (Payment Card Industry Data Security Standard) to protect cardholder data.

7. Biometric Authentication

• What it does: Uses fingerprints, facial recognition, or voice recognition for secure payments.

• Example: Apple Pay and Google Pay use biometric verification.

8. Firewalls and Anti-Malware Protection

• What it does: Blocks unauthorized access and prevents malware attacks.

• Example: Banks and e-commerce platforms use firewalls to secure online payment systems.
