ONE vulnerability can take a router. How can consumer grade routers protect consumers?
~But how can normal consumers who don't have any network knowledge use them properly without any problems? I see so many users who have issues with AiProtection and 2 way IPS something whether they have knowledge or not. Also I see so many users who have a lot of issues with Software Firewall such as Internet Security things. There are a lot of users who are still using old Firmwares. Most of them don't care about Firmware upgrading. Some of them are using old Firmwares because of stability. Are they safe?~
I have read, watched, heard over the years that what happens often times is that people who don't know how to properly network often have a "knowlegable" family member, friend, co-worker help them. It is a sticky issue. So many are on the internet on multiple devices and don't understand what the potential risks and helpful mitigations are (nothing being 100% certain). I do think that, in the current environment, businesses try to configure their systems to be easy to use for the "average" user with options for additional features for those inclined to put in that effort.
regarding firmware (and software) updates. I think it's only become a serious concern in the recent past, how those issues could be leveraged by criminal elements and others for serious harm. That's why automatic firmware/software updates haven't been the industry norms. Also, sometimes those updates, improperly applied can cause more problems. (Think some recent Microsoft updates) That is why when you have a piece of HW or Software, have it registered/put on an e-mail list.
Case in point:
https://www.win-rar.com/singlenewsv...s]=116&cHash=ab1dd0ca4b801016fba0a9562a5b8e40
the ACE archive was fairly popular in its day, closed source, and not used very often anymore. But clever individuals discovered a way to leverage the way ACE archives are decrypted by file decryption software to open a serious security hole. Current versions of Winrar (and many other decompression programs) will no longer support ACE decompression as a result. People who registered their winrar programs got the immediate heads up to update/upgrade the program. I'm under the impression that there are 500 million users of winrar out there. How many updated? Not the fault of business, consumers need to care and be responsible.
That is why I run one HW security device behind another (whether they be routers, firewalls etc), my current basic configuration. So that vulnerable IoT devices can't(or shouldn't be able to) get further into my home network. At least in theory, as I understand NAT and packet routing.
