How does CMTS MIC work- what is md5'd?

[megadork]

Open your config file in a hex editor, the MD5 MIC hash is always between "07 10" and "FF" towards the bottom.

Thanks for your replies gentlemen.

Is there any system in place that tries to prevent the modem from simply saying "here's how I'm configured, exactly as you told me CMTS" and then proceeding to configure itself differently using a config file stored locally? I'm new to this scene and just trying to understand the security model a bit better as it relates to CMs modifying / using a config other than intended.

Thanks again.
