Refering to the following topic: http://arstechnica.com/security/2016/11/notorious-iot-botnets-weaponize-new-flaw-found-in-millions-of-home-routers/?utm_content=buffer8f018&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer
There is a Mirai malware attacks related to the TR-069. which use the TR-069 opened port 7547 to make attack.
Is it a classic port attack?
I think to fix that attack I have:
- to use a random port for each device instead of the known port 7547
- to add a firewall rule in my iptable. The firewall rulle will allow to accept connection request of the opened port from only a know IP address
Are my suggestion is sufficient to protect my devices against this attack?
