IoT Security Compliance
Many security regulations require encryption, authentication, and monitoring mechanisms, but do not prescribe how these are verified.
The validation methods used here map to requirements in common IoT security frameworks by confirming actual device behavior.
Applicable Standards & Regulations
EU Radio Equipment Directive (RED)
Requires protection against unauthorized access, personal data protection, and fraud prevention for radio equipment placed on the EU market.
Who this affects: Manufacturers, importers, and distributors of wireless devices sold in the EU.
Effective: August 2025 for cybersecurity requirements.
ETSI EN 303 645
Security baseline for consumer IoT covering secure communication, authenticated updates, access controls, and personal data protection.
Who this affects: Consumer IoT manufacturers seeking to demonstrate security best practices.
Common use: Referenced for RED compliance and voluntary security assessments.
NIST IR 8259 Series
Foundational cybersecurity activities for IoT device manufacturers, including secure development, updates, and incident response.
Who this affects: US-focused IoT manufacturers and federal suppliers.
IEC 62443
Framework covering access control, system integrity, and data confidentiality for industrial automation and control systems.
Who this affects: Industrial IoT and embedded systems in critical infrastructure.
What Validation Confirms
| Requirement Area | What is Tested |
|---|---|
| Secure Communication | Encryption presence, protocol strength, key exchange validation |
| Access Control | Authentication mechanisms, default credentials, unauthorized access prevention |
| Network Security | Service exposure, unnecessary ports, attack surface |
| Monitoring & Logging | Event capture, log accessibility, detection capability |
Common IoT Security Vulnerabilities
Unencrypted Wireless Communication
BLE, WiFi, and Zigbee traffic transmitted in plaintext, exposing device commands and user information.
Detection: Packet capture during normal operation
Weak or Default Credentials
Factory default passwords or hardcoded credentials allowing unauthorized device access.
Detection: Credential testing and brute force resistance
Exposed Network Services
Unnecessary open ports, debug interfaces, or unprotected management interfaces.
Detection: Port scanning and service enumeration
Missing Security Event Logging
Failed authentication attempts or suspicious behavior goes undetected and unlogged.
Detection: Exploitation testing and log inspection
EU RED Compliance Timeline - August 2025
After August 1, 2025, all radio equipment (WiFi, Bluetooth, cellular) sold in the EU must comply with cybersecurity requirements under Article 3(3)(d), (e), and (f).
Recommended timeline for manufacturers:
- • 12-18 months before launch: Initial security assessment and validation
- • 6-12 months before launch: Implement fixes and re-validate
- • 3-6 months before launch: Final compliance verification and documentation
- • Before August 2025: Complete conformity assessment and prepare technical file
Frequently Asked Questions
Is this a certification or formal compliance audit?
No. This is independent technical validation that produces evidence you can use for regulatory submissions, audits, or internal security assessments. We document what your device actually does, which supports your compliance efforts but does not replace formal certification where required.
How long does validation take?
Depends on device complexity. A simple BLE device might take 1-2 weeks. An embedded Linux gateway with multiple protocols might take 4-6 weeks. We'll scope the timeline during initial consultation.
What if you find security issues?
We document findings with evidence, explain the security impact, and provide remediation guidance. If needed, we can re-test after fixes are implemented to verify the issues are resolved.
Do you need physical device access?
Yes, for most testing. We need at least one device to perform packet capture, network scanning, and other hands-on validation. In some cases, remote testing may be possible if network access can be provided.
Can validation evidence be shared with regulators or auditors?
Yes. All evidence is documented professionally and can be included in technical files, compliance submissions, or provided to third-party auditors. We can also clarify findings or methodology if follow-up questions arise.
