  6. Cybersecurity is crucial because it protects sensitive data, systems, and networks from cyber threats like hacking, malware, ransomware, and data breaches.

Social engineering in security refers to the manipulation of people into performing actions or divulging confidential information, often by exploiting human emotions such as trust, fear, or urgency. Instead of attacking a computer system directly, social engineering targets the human element of security, making it one of the most effective and dangerous forms of cyberattack.\Phishing is a type of cyberattack where attackers try to trick you into giving up sensitive information—like usernames, passwords, credit card numbers, or personal data—by pretending to be a trustworthy entity. It often happens via email, but can also occur through text messages (smashing), phone calls (vishing), or fake websites.

 Securing a network from attacks involves a layered, defense-in-depth strategy. No single tool or method is enough — it’s about combining technologies, policies, and practices to reduce risk and detect threats early.

Here’s a step-by-step guide to securing a network:

🛡️ 1. Perimeter Security

🔸 Firewalls

  • Control incoming and outgoing traffic using rules.

  • Use next-gen firewalls (NGFW) to inspect deeper into packets.

🔸 Intrusion Detection & Prevention Systems (IDS/IPS)

  • IDS detects suspicious activity and alerts.

  • IPS can actively block or drop malicious traffic.

🔒 2. Network Segmentation

  • Split the network into smaller zones (e.g. internal, guest, IoT).

  • Use VLANs and subnets to isolate sensitive data or critical systems.

  • Prevent lateral movement in case of a breach.

🔍 3. Endpoint Security

  • Install antivirus/EDR (Endpoint Detection & Response) on all devices.

  • Apply mobile device management (MDM) for phones/laptops.

  • Keep OS and applications updated with security patches.

🔐 4. Authentication & Access Control

  • Use strong, unique passwords and multi-factor authentication (MFA).

  • Apply least privilege: only give users access to what they need.

  • Implement role-based access control (RBAC) or zero trust policies.

📜 5. Security Policies and User Training

  • Enforce policies for:

    • Acceptable use

    • Remote access

    • Incident response

  • Conduct regular security awareness training to defend against phishing/social engineering.

🧰 6. Monitoring and Logging

  • Use a SIEM (Security Information and Event Management) system to collect logs and detect anomalies.

  • Monitor:

    • Login attempts

    • File access

    • Network traffic

  • Set alerts for suspicious behavior (e.g., brute-force login attempts, data exfiltration).

🔄 7. Patch Management

  • Regularly apply patches to:

    • Operating systems

    • Routers/switches/firewalls

    • Third-party apps (e.g., browsers, Java, Adobe)

  • Automate where possible using tools like WSUS, SCCM, or third-party patch managers.

☁️ 8. Secure Remote Access

  • Use VPNs or Zero Trust Network Access (ZTNA).

  • Disable direct access (like RDP) from the internet unless absolutely necessary and protected.

  • Monitor VPN usage and flag suspicious activity.

🧱 9. DDoS Protection

  • Use services like Cloudflare, AWS Shield, or Akamai to absorb and filter large-scale attacks.

  • Rate-limit access to critical services.

📦 10. Backups & Incident Response

  • Perform regular, encrypted backups — both onsite and offsite.

  • Test restoration processes.

  • Maintain an incident response plan: know how to isolate, contain, and recover from attacks.

🧬 Bonus: Advanced Tools

  • Network Access Control (NAC): only allow approved devices.

  • Deception technologies: fake services that trap attackers.

  • Threat hunting: proactively search for undetected threats inside the network.
