System hacking involves gaining unauthorized access to computer systems and data by bypassing authentication procedures and security policies. This process is often carried out by adversaries aiming to establish persistence, extract data, escalate privileges, and scan networks for further exploitation.
Key Points
- Definition: System hacking is the process of obtaining unauthorized access to computer systems and data.
- Adversary Objectives: Establish persistence, extract relevant data, escalate privileges, and scan for lateral movement within the network.
Evolution of System Hacking
Changes Over Time
- Past: Two decades ago, IT networks primarily consisted of workstations, servers, and mainframes.
- Present: Today's IT landscape includes a variety of new systems, such as IoT devices.
Current Challenges
| Challenge | Description |
|---|---|
| IoT Security | Limited security due to rapid innovation. |
| Cloud Migration | Increased risks of data leaks and intellectual property theft. |
| OT Interconnection | Enhanced security needed for operational technology devices connected to IT networks. |
Role of the Ethical Hacker
Adapting to New Threats
- Continuous Learning: Constant skill development to identify and mitigate vulnerabilities.
- Tools: Utilization of frameworks like
Metasploitfor system exploitation.
Tools and Techniques
- Metasploit: A penetration testing framework with a vast collection of exploits and payloads.
- Post-Exploitation Tools:
Empire,PowerSploit,PowerViewfor Windows environments. - Scripting:
Pythonfor automating exploitation tasks.
Security Measures
Configuration and Management
- Centralized Management: Use a centralized configuration management solution to ensure consistent system configurations.
- Strict Security Policies: Implement strict security policies during the configuration of new systems.
Preventive Measures
- Regular Updates: Strict and frequent update policy.
- Strong Authentication: Complex passwords and two-factor authentication.
- Security Tools: Deploy antivirus, exploit mitigation frameworks, and firewalls.
- Network Segmentation: Disable unnecessary services and segment the network to isolate systems.
Conclusion
Continuous Vigilance
- Network Monitoring: Regularly search for unauthorized or unused devices in the network.
- Documentation: Document every system and network asset.
