As security systems become more connected, they also become targets for cyberattacks. Understanding and mitigating these threats is critical for security professionals.

Common Threat Vectors

• Default Credentials: Unchanged passwords on cameras and NVRs
• Firmware Vulnerabilities: Unpatched security flaws
• Network Exposure: Devices accessible from internet
• Supply Chain: Compromised hardware or software
• Insider Threats: Malicious or negligent users

Real-World Incidents

Recent attacks have compromised thousands of cameras, demonstrated ransomware targeting NVRs, and shown access control system exploits.

Mitigation Best Practices

• Change all default credentials immediately
• Implement network segmentation (VLANs)
• Regular firmware updates and patches
• Enable encrypted communications (HTTPS, TLS)
• Conduct regular security audits

Compliance Requirements

NDAA Section 889 compliance, GDPR considerations for video data, and industry-specific regulations (HIPAA, PCI-DSS) must be addressed.
