10 Tips to Avoid Such Threats in the Future:
- Regular Software Updates – Keep all ICS software and firmware up to date to ensure known vulnerabilities are patched promptly.
- Use Strong Authentication Mechanisms – Implement multi-factor authentication and strong password policies to prevent unauthorized access.
- Network Segmentation – Isolate ICS from business networks and the internet to minimize the attack surface.
- Monitor Network Traffic – Use intrusion detection systems (IDS) and network monitoring tools to detect abnormal activity.
- Employee Training – Conduct regular cybersecurity training to help employees recognize phishing attacks and social engineering tactics.
- Incident Response Plan – Establish a clear incident response plan to handle cyberattacks and minimize damage quickly.
- Implement Firewalls and VPNs – Use firewalls to block unauthorized traffic and VPNs for secure remote access.
- Perform Regular Security Audits – Conduct security audits to identify and mitigate vulnerabilities in ICS networks.
- Limit Privileged Access – Restrict admin rights to only essential personnel and enforce the principle of least privilege.
- Deploy Security Patches Immediately – Apply security patches as soon as they become available, especially for critical vulnerabilities.
