The security of networks (especially wireless networks) has become more and more popular due to the growing popularity of networked devices using protocols such as machine-to-machine (M2M). The world outside is dangerous everywhere, and there are still many who want to undermine the social and critical infrastructure needed to build these connections.
For embedded wireless or wired M2M systems based on MCU, MPU or FPGA, especially in today's generally networked but vulnerable world, good security requires the following measures that all use standard encryption algorithms:
Network communication security using TLS
Virtual Private Network Security (VPN) using IPSec
Secure login and system interaction using SSH
Secure file transfer using SFTP
Secure email - encrypted email and secure mail server links
Secure website server - https
Secure management - SNMP v3
Secure boot with encrypted and checked images
This article briefly discusses the application of the above security measures to M2M and the overall system level considerations. M2M systems require a high degree of security to protect information and systems. Without such seamless integration and testing, there will be security holes, the system is vulnerable to attack, and terrible consequences can occur.
