But it may be worth it to contact Cisco TAC and ask them about security updates and see what happens. If you are not the original licensed owner of the router then TAC may hang up on that. Their rationale is that while hardware can be sold and transferred to a new owner, that the software is sold to the original owner and software is not transferable. 2) Officially Cisco says that it will do software replacement for original licensed purchaser of the router.

But if your router is still an officially supported model then there is some possibility that you could get an update from TAC. So what model of router do you have and has it reached its End Of Support Date? If your router is past its End Of Support Date then there will be no security updates. So let us consider a couple matters of practicality: 1) Is your router eligible for support updates? For every router model Cisco establishes a date after which that model is no longer sold and then a date after which it will not support the software. In many of the vulnerability announcements that Cisco releases there is a provision for routers not under maintenance contract to obtain a software update that addresses the vulnerability directly from Cisco TAC and without charge. Refer to thé Cisco 3900 Series, 2900 Series, and 1900 Series Software Configuration Guide for detailed information about using Cisco IOS software for configuring the router. You make an interesting point about security flaws and software updates. The software shouId be configuréd with the foIlowing parameters: 9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control.
