Sixteenth Day

Assalamualaikum....hye-hye...

#Today I proceed with IP camera. I suspect the reason of unsuccessful on IP camera because can't enable for auto port forwarding. But I more interest to find the reason why UPnP can't be enable because UPnP is a set of networking protocol that permits networked devices. If UPnP can't be enable, it can't permit IP camera to access on internet.

Problems with UPnP:

1. Lack of authentication
   * UPnP does not implement any authentication,so UPnP device implement the Device Security Service. It also exist a non standard solution called UPnP-UP(Universal Plug and Play-User Profile) that allow user authentication and authorization mechanisms for UPnP devices and applications. Many UPnP device implementations lack authentication mechanisms and by default assume local systems and their users are completely trustworthy. Most notably, routers and firewall running the UPnP IGD protocol are vulnerable to attack since the framers of the IGD implementation omitted a standard autentication method. This allow a router implementing the UPnP IGD protocol to be controlled by a malicious web site when someone with UPnP-enabled router simply visits that website. Not all router can have such things as DNS server setting altered by UPnP because much of the specification (including LAN Host Configuration) is optional for UPnP enable routers.
2. Accepting WAN request
   *Daniel Garcia developed a tool designed to exploit a flaw on some UPnP IGD device stack that allow UPnP request from WAN but the problem is widely propagated around the world, with scan showing at least 500000 vulnerable device at a time.
3. Other problems
   *UPnP does not have a lightweight authentication protocol, while the available security protocols are complex. So, some UPnP devices ships with UPnP turned off by default as a security measure.
   
   #I try to change on setting for port forwarding on router configuration, but there also the problem because the port that used by viewnetcam or IP camera we just know about the default port only. It is 80 for the default. If we use the special port for IP camera, we must set the viewnetcam add the number of the port. For example port is 80, the link should be http://hiis2012.viewnetcam.com:8000.
   
   #I can't solve the problem yet, and it will continue tomorrow. We bring back IP camera and router to test at home.
