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.

ELK Stack Setup (Windows + Winlogbeat + Kibana)

A complete solution for log management, security monitoring, and real-time analytics

1. Start Elasticsearch

  • Open PowerShell
  • Navigate to Elasticsearch:
  • cd C:\elasticsearch\elasticsearch-9.3.2\bin.\elasticsearch.bat

Verify:

👉 http://localhost:9200

2. Start Kibana

  • Go to Kibana folder:

cd C:\kibana-9.3.2\bin

.\kibana.bat

3. Fix Kibana Authentication

  • Do NOT use elastic user
  • Use service account instead:

In kibana.yml:

elasticsearch.hosts: [“http://localhost:9200”]

elasticsearch.username: “kibana_system”

elasticsearch.password: “<your-password>”

4. Configure Winlogbeat

Edit winlogbeat.yml:

winlogbeat.event_logs:

– name: Application

– name: System

– name: Security

output.elasticsearch:

hosts: [“http://localhost:9200”]

username: “elastic”

password: “<your-password>”

5. Test Winlogbeat

.\winlogbeat.exe test config

.\winlogbeat.exe test output

Expected:

Config OK

connection… OK

6. Start Winlogbeat

.\winlogbeat.exe -e

7. Create Data View (Index Pattern)

In Kibana:

  • Go to Stack Management → Data Views
  • Create:
  • winlogbeat-*
  • Select @timestamp

8. Verify Logs (Discover)

  • Go to Discover
  • Select winlogbeat-*

Test filters:

event.code: 4624

event.code: 4625

✔ 4624 → Successful login

❌ 4625 → Failed login

9. Create Dashboard

  • Go to Dashboard → Create
  • Add visualization (e.g. bar chart)
  • Use:
    • X-axis: @timestamp
    • Breakdown: event.code

Common Issues

❌ Kibana not loading

  • Check Elasticsearch is running

❌ Permission error

  • Don’t use elastic in Kibana

❌ No logs

  • Ensure Security log is enabled in Winlogbeat

Final Result

  • Logs visible in Discover
  • Data view created
  • Dashboard working
  • Ready for alerts & monitoring
