IPv4 Headers Investigated

Posted by CmdrTaco on from the that-makes-a-lot-of-sense dept.

An anonymous reader writes "New security measures are being suggested (see RFC 3514) for the IPv4 header. The measures include a bit that can be set and unset according to whether the packet is secure or not. Due to the important security implications, anyone coding client/server internet applications might want to take a look."

    I'm employing a Full Software Development Life Cycle Methodology (FSDLCM) with Extreme Programming to modify my TCP stack for an Evil Bit Payload Control System(EBPCS). Using the latest Rational Tools I've already made several lengthy iterations on a UML modeling with advanced design patterns including the Inactive Observer and Simpleton Factory. The enabling features of Rational Rose groupware has empowered everyone from marketing to sales and janitorial staff to participate and pool their synergism in the IT architectural process. ~
