I wrote earlier that having cameras on a VLAN does not solve or reduce the threat potential of allowing a plugin to infect a PC. They are completely different.
And, for Teken's post, I do have a hole in my network security. Someone could smash one of my exterior cameras, and plug a laptop into the ethernet cable. How does that, in any way, relate to whether a plugin attempting to modify my PC is safe to execute or not?
I appreciate participating in this forum and learned some things. But, as many can see, my concerns over network security differ from the assurances presented by others. I am very much out of step compared to other comments posted. No worries- I will cease poking the beast ....
If you take the time to search all of the (Best Practices) as it relates to infrastructure and network security.
You would have quickly found out that port security management is one of several methods and solutions used to restrict, detect, deny, and track a physical Ethernet port from being used.
As you stated and asked what would happen if someone was able to remove a camera and plug in their own device whether it be a compromised video camera or a computer / network device?!?
To the attacker - nothing . . .
Their device would not be allowed on the network and the port would be summarily disabled.
From the security administration team lots of things would happen and be known the instant the camera was disconnected.
They would know immediately the device was tampered with and disconnected. Followed by your scenario of a new (unknown) device was on the network.
How???
All of the security elements I stated up above and many more not listed for brevity.
As it relates to the (Plugin) I’ll ask you to read my reply as it relates to how and why. There isn’t anything I have stated that can’t be done in a properly setup network.
It simply requires time, resources, and finances to make it so. Keeping in mind if we just ignore all the fancy software elements I have stated.
How would Bob achieve the same on a shoestring budget???
- Separate, dedicated computer
- Isolated physical network from the main
- No physical Internet access / wireless
A person can literally buy a $20 router, $45 POEswitch, $50 computer and have an isolated and dedicated video security system. If their means are higher than they can buy whatever their hearts desires!
It doesn’t matter what potential virus / malware is present. It can’t infect, communicate, or impact anything else.
It’s literally impossible . . .
