Corporate official websites can set access restrictions to prevent black market intrusion through several technical measures. Here’s how:

  1. IP Whitelisting/Blacklisting: Restrict access by allowing only trusted IP addresses (whitelisting) or blocking known malicious IPs (blacklisting). For example, if a company identifies suspicious traffic from specific regions, it can block those IP ranges.
    Example: A financial institution allows access only to its employees' office IP addresses and blocks all others.

  2. Geolocation Filtering: Block traffic from high-risk countries or regions where black market activities are prevalent.
    Example: An e-commerce site restricts access to users in countries with a history of fraudulent transactions.

  3. Rate Limiting & CAPTCHA: Prevent automated bots from scraping data or launching attacks by limiting request rates and requiring CAPTCHA verification.
    Example: A ticketing website uses CAPTCHA to block bot registrations and rate limits API calls to prevent scraping.

  4. Web Application Firewall (WAF): Deploy a WAF to filter malicious traffic, such as SQL injection or DDoS attacks, before it reaches the website.
    Example: Tencent Cloud’s Web Application Firewall (WAF) helps block common web exploits and provides real-time threat detection.

  5. Authentication & Access Control: Require strong user authentication (e.g., multi-factor authentication) for sensitive areas of the website.
    Example: A corporate portal restricts access to financial data by requiring employees to log in with MFA.

  6. Monitoring & Logging: Continuously monitor traffic patterns and log suspicious activities for analysis.
    Example: Tencent Cloud’s Cloud Monitor and Log Service help track abnormal access attempts and generate alerts.

  7. HTTPS & Encryption: Enforce HTTPS to encrypt data in transit, preventing man-in-the-middle attacks.
    Example: A healthcare website uses TLS 1.3 to secure patient data transmission.

For enhanced security, Tencent Cloud’s DDoS Protection and Security Center can further safeguard websites from large-scale attacks and vulnerabilities.
