Vulnerability management

LILIN are always working on maintaining the highest level of security for our products and customers. LILIN conducts product security maintenance throughout the product’s life cycle. In short, the vulnerability management is described below:

  • Risk analysis and assessment of vulnerabilities with reference to the CVSS 3.0
  • Security guidance throughout development by CIA-AAA (confidentiality, integrity, availability, authentication, authorization & accounting)
  • Secure programming guidance and FIPS 140-2 for sensitive data protection & cryptography
  • Vulnerability and open ports scanning in the testing phase
  • Third-party vulnerability auditing for LILIN products by our security partner Deloitte Taiwan
  • Security controls and checkpoints for software/firmware releasing, loading and storing

  • Based on the risks reported and discovered, we classify the severity of vulnerabilities as either critical or non-critical. The process for identifying a security vulnerability is discover, analyze, prioritize, remediate & track.

    LILIN release firmware updates on a regular basis to address bug fixes and non-critical vulnerabilities that are found in our products. Occasionally, there may be a critical vulnerability discovered that leaves our devices vulnerable to attack. LILIN will focus its priorities to fix this issue immediately outside of the regular schedule and release a firmware fix for the vulnerable device.
