M2M follows a layered, defense-in-depth network security model using U.S. National Security Agency guidelines, knowledgeable, experienced IT professionals, and industry networking best practices to secure M2M solutions.

• Availability: System up time is maintained at the highest levels through physical security, redundancy, network protection (firewall, IDS, etc.), hardened OS, and ongoing security audits.
  
  
• Integrity: M2M ensures data is not modified or corrupted through use of encrypted data signatures, authentication, reliable storage (RAID5), reliable network (redundancy), CRC, and physical and logical restricted access.
  
  
• Confidentiality M2M ensures restricted access to data through use of encryption (SSL - RSA 1024/3DES/MD5, VPN - LPTP, or IPsec), login/password, PKI & biometrics (optional).
