🔐 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.
