Hard wire security

Hard wire security

My modem is hardwired to the Router.  The Router is then hardwired to my desktop.  Is/are there any Router added electronics, (chips, relays, etc.) built into the Router that are between the electrons comming into the modem and reaching the desktop?  In other words is the signal from modem to desktop just as secure With the Router as Without the Router?  I have a Model R6900v2  Nighthawk AC1900 Router.       Thanks

Re: Hard wire security

More secure with the router. Your router has a built in firewall to protect you from the outside.

Re: Hard wire security

Its great that the Router has a firewall.  So does the desktop.  The question is "As I pull or push stuff in/out of the internet, from the hardwire between the modem and a box called a Router.  And then have these signals hardwire to the desktop from this box.  Is there any chance that an intruder can get into this electron flow?  In other words does all this wiring make for one secure pipe for the in/out signals?"  Can, via the antennae, an intruder break into this pipeline?

   No. but "electron flow" is not the relevant concept here.

> [...] Can, via the antennae, an intruder break into this pipeline?

   What does "the antennae" mean to you?  The router's wireless-network
antennae?

   Here's an experiment for you: Find an old portable AM radio, and hold
it near your Ethernet cable.  Do you hear any noise (which might vary
with your network activity)?  I'd assume so.  I'd expect your computer
alone, without any network connection, to radiate similar (radio) noise.

   Your wired network is not what I'd call vulnerable to practical
attacks.  Against what kind of threat are you trying to defend, nosy
neighbors, or the NSA?  Is your house wrapped in well-grounded metallic
screening?

   Could the NSA park a truck outside your home with a big parabolic
dish on top, collect this noise, analyze it (using more computers than
you've ever seen), and extract some of your data from it?  I'd bet on
it.  Does this worry you?

Re: Hard wire security

So, to restate.  Lets assume a neighbor cracks my greater than 10 place password and is able to tap into the Router, (through the antenna, just like my phone does).  Is there manufacturer installed circuitry between the antenna access function and the funtionality that is the wire entering the Router from the modem and thence the wire leading from the Router to the desktop?

Re: Hard wire security

Well on further reflection.  I'll assume that there has to be circuitry in the Router that "splits" the incomming signal from the modem into the wired output ports and the wireless function.  So the additional questions become.  1.  Does the router store any information?  e.g. bank login, that passes to/from the hardwired desktop.  If so might this become accessble by a neigboor entering the Router thru the wireless functinality, due to internal circuitry,    and 2. The circuitry of the "split",  does the community know if it is subject to highjacking by the aveage neigboor through the wireless functionality and thus tapping into the data flowing thru the "wired" functionality.?  If "Wireless Routers" get/require periodic secuurity upgrades, what are the true vulneralbities for the average bloke?

   Then he's on your LAN, just like any of your legitimate (wired or
wireless) devices.  (I don't pay much attention to this stuff, but ten
characters sounds a little short to me.)

   Generally, no.  The only wireless-wired isolation which should exist
applies to a "guest" network, and that's optional.


> [...] 1.  Does the router store any information? [...]

   It shouldn't.  It should be too stupid to recognize what's
interesting, and its storage capacity is too limited to store much.

  It's more software than "circuitry", but, as above, anyone who joins
the wireless network could see messages sent to/from other devices on
the LAN.

   I'd say generally, pretty small but you won't a guarantee from me.

Re: Hard wire security

@NewguyPQ, I think you are being a bit paranoid here.

 

First if you have the wireless function turned off, why are you using a router when a plain old switch would do?

 

Short answer, YES, routers can be infected... Google "router infection" and see for yourself.

 

Some tests are on-line, like THIS ONE.

 

Look here, https://lifehacker.com/how-to-protect-your-router-from-the-latest-malware-atta-1826280946, as well. Note that some Netgear routers are LISTED as vulnerable.

   "router" and "switch" are spelled differently for a reason.  A router
and a switch are not equivalent devices.
