 How to Secure Sensitive Data in a Network (in English)

Securing sensitive data in a network is essential to protect it from unauthorized access, data breaches, or cyberattacks. This involves using a combination of technical controls, best practices, and security policies.

🔒 1. Encryption

a. Data in Transit

  • Use TLS (Transport Layer Security) or HTTPS to encrypt data when it's moving between systems.

  • Protects data from being intercepted or altered during transmission.

b. Data at Rest

  • Encrypt stored data using technologies like:

    • AES-256 encryption

    • AWS KMS, Azure Key Vault, etc.

  • Apply encryption to databases, file systems, and backups.

🔑 2. Access Control

  • Use strong authentication (e.g., passwords + MFA).

  • Apply the principle of least privilege (give users only the access they need).

  • Use Role-Based Access Control (RBAC) or Attribute-Based Access Control (ABAC).

🛡️ 3. Firewalls and Network Segmentation

  • Use firewalls to block unauthorized traffic.

  • Segment the network into zones (e.g., public, private, admin) to isolate sensitive systems.

  • Restrict access to databases and internal APIs.

🧪 4. Regular Security Testing

  • Perform vulnerability scans, penetration testing, and code reviews.

  • Test for common threats like SQL injection, XSS, and buffer overflows.

👁️ 5. Monitoring and Logging

  • Monitor network traffic for unusual behavior using tools like:

    • Intrusion Detection Systems (IDS)

    • SIEM (e.g., Splunk, AWS CloudTrail)

  • Log all access and actions, especially on sensitive data, for auditing.

🗝️ 6. Secure Authentication Methods

  • Use multi-factor authentication (MFA) for all critical systems.

  • Prefer OAuth2, OpenID Connect, or SAML for secure single sign-on.

📦 7. Data Masking and Tokenization

  • Use data masking to hide sensitive fields (e.g., hide credit card numbers).

  • Use tokenization to replace sensitive data with non-sensitive equivalents in non-secure environments.

🔁 8. Patch Management

  • Regularly update systems and applications to fix known security vulnerabilities.

  • Automate patch deployment where possible.

📚 9. Security Policies and Training

  • Educate employees about phishing, social engineering, and safe data handling.
