    Study Notes

    E-commerce Security Issues

    • Integrity: Safeguarding against unauthorized changes to data.
    • Nonrepudiation: Ensuring parties cannot deny their actions after transactions.
    • Authenticity: Verifying the source of data and identity.
    • Confidentiality: Preventing unauthorized access to sensitive information.
    • Privacy: Maintaining control over personal data and its disclosure.
    • Availability: Ensuring data is accessible and not delayed or removed.

    Data Interception Points

    • Data can be intercepted in three main areas:
      • In the browser: Users input sensitive information which can be accessed if the device is left unattended.
      • Between the browser and the server: Data in transit may be intercepted, even if encrypted.
      • In the server: Vulnerable to external attacks and unauthorized access.

    Security Measures

    • Encryption: Converts plaintext to ciphertext, protecting data during transmission.

      • Symmetric key cryptography: Same key for encryption and decryption.
      • Public key cryptography: Different keys for encryption (public) and decryption (private).

    • Digital Signature: E-signature that verifies the authenticity of information through encryption.

    • Security Certificates: Unique digital IDs for website identity verification.

    Common Security Threats

    • Hacking and Cyber Vandalism: Includes website defacement and malware creation.
    • Credit Card Fraud: Unauthorized use of credit card information for purchases.
    • Spoofing: Impersonating trusted entities to steal sensitive data.
    • Malicious Code: Includes viruses, worms, and Trojans that harm systems.
    • Denial of Service Attack: Overloading systems to restrict access for authorized users.
    • Sniffing: Eavesdropping on network traffic to capture sensitive information.

    E-commerce Security Solutions

    • Implement HTTPS and SSL Certificates: Encrypt data transfer, improving security and search ranking.
    • Use Anti-Malware and Anti-Virus Software: Protect systems from various malware infections.
    • Secure Admin Panel and Server: Use strong, frequently changed passwords and restrict access based on roles.
    • Safeguard Payment Gateways: Avoid storing credit card data; use third-party processors.
    • Deploy Firewalls: Block unauthorized access and mitigate cyber-attacks.
    • Educate Employees and Clients: Provide training on secure data handling and update access rights for former employees.
    • Perform Regular Security Scans: Identify malware and ensure data backups.
    • Conduct Risk Assessments: Catalog information assets and their importance to the organization.
    • Develop a Security Policy: Define protection protocols and roles.
    • Create an Implementation Plan: Outline actionable steps for achieving security goals.
    • Establish a Security Organization: Dedicated team to manage security policies and guidelines.

    Drawbacks of Symmetric Key Encryption

    • Vulnerability to Key Theft: Same key must be shared over potentially insecure channels.
    • Management Complexity: Requires a vast number of keys for millions of users.

    Public Key Encryption

    • Utilizes a pair of keys for secure messaging: one public (shared) and one private (kept secret).
    • Digital certificates link public keys to identities, authenticated by trusted Certification Authorities (CAs).
    • Digital Certificate Details: Includes subject's name, public key, serial number, expiration date, issuing authority’s signature, and more.
