🔐 Secure Your Network Infrastructure

  • Firewall Configuration: Always enable and properly configure firewalls to block unauthorized access. Use tools like iptables or Windows Firewall for granular control.
  • Intrusion Detection Systems (IDS): Deploy IDS to monitor network traffic for suspicious activity. Example: Snort or Suricata.

🚀 Regular Updates and Patch Management

  • Keep Software Updated: Schedule regular updates for OS, applications, and firmware. Use Ansible or Chef for automated patching.
  • Patch Critical Vulnerabilities First: Prioritize patches for high-severity vulnerabilities (e.g., CVE-2023-1234).

🧠 Implement Strong Access Controls

  • Role-Based Access (RBAC): Assign permissions based on user roles to minimize risks. Example: RBAC Configuration Guide.
  • Disable Unused Ports: Close unnecessary network ports (e.g., Port 22) to reduce attack surfaces.

📡 Monitor and Log Network Activity

  • Centralized Logging: Use ELK Stack (Elasticsearch, Logstash, Kibana) for real-time monitoring.
  • Analyze Traffic Patterns: Detect anomalies with tools like Wireshark.
