CYBER SECURITY IN MODERN WORLD

      Cybersecurity is the practice of protecting computers, networks, data, and digital systems from cyber threats such 
      hacking, malware, phishing, and data breaches. 
      In today's interconnected world, cybersecurity is essential for safeguarding personal information, business operations,   
      financial transactions, and critical infrastructure. 
      As technology advances, cyber attacks are becoming more sophisticated, making strong security measures increasingly 
      important.

      Transition to Quantum Security

     With the development of quantum computing, traditional encryption methods may become vulnerable because powerful 
     quantum computers could potentially break current cryptographic algorithms much faster than classical computers.
     Quantum security, also known as post-quantum cryptography, focuses on developing new encryption techniques that can
     resist attacks from both classical and quantum computers.
     This emerging field aims to ensure long-term data protection and secure communication in the future quantum era.

Insights and tips on protecting your digital life every day.

Building a Home SASE Lab with EVE-NG

Step 1: Installing EVE-NG on VMware

  • Installed EVE-NG Community Edition using ISO on VMware
  • Configured hostname and root password
  • Ensured VM network adapter was set to NAT
  • Verified IP address assigned to the VM

Step 2: Accessing EVE-NG Web Interface

  • Accessed EVE via browser using:http://<EVE-IP>
  • Encountered login issues → resolved by resetting admin credentials in database
  • Successfully logged in with:username: admin
  • password: …

Step 3: Adding First Node (VPCS)

  • Downloaded VPCS image on Windows
  • Uploaded it to:/opt/unetlab/addons/qemu/vpcs/
  • Fixed permissions:/opt/unetlab/wrappers/unl_wrapper -a fixpermissions
  • Added VPCS node via:Add Object → Node

Step 4: Connecting and Testing Nodes

  • Added two VPCS nodes
  • Connected them using network links
  • Assigned IP addresses:ip 192.168.1.2/24 ip 192.168.1.3/24
  • Verified connectivity using:ping

Step 5: Adding a Cisco Router

  • Uploaded Cisco router image to:/opt/unetlab/addons/dynamips/c3725/
  • Fixed permissions
  • Added router node to lab
  • Accessed CLI and configured basic settings

Final Result

  • Fully working EVE-NG lab environment
  • Successfully deployed:
    • Virtual PCs (VPCS)
    • Cisco Router
  • Verified network connectivity

Conclusion

This setup provides a powerful and flexible environment for hands-on practice in networking and cybersecurity. By combining virtualization and real network images, EVE-NG enables building enterprise-level labs directly on a personal machine.
