After studying networking for some time, I just realize that the Layer 3 and Layer 2 don't care about the content of the packets they forward. All they care is the header, and further processing of the payload is left to higher layers.

I've identified a particular IPv4 /24 subnet that is responsible for a great deal of the unsolicited packets being rejected by my router (and making my log files larger than I'd like them to be). As a traffic mitigation technique - or if ...
I am working on providing wireless infrastructure suggestions to a client like what software, hardware and equipment will be required to a client in order for them to set up the wireless infrastructure. Its a production site that is quite ...
This question is about encryption in data communications, defined broadly to include:
Line scrambling at layer 1
MACsec at layer 2
IPsec at layer 3
TLS at layer 4
etc.
All of these encryption methods require secrets to be installed on th...
I'm not a networking person but am being required to integrate some of my devices into a larger enterprise network. I'm trying to understand firewall lingo, and I'm starting to realize that firewall appliances are pretty complex.
Let's say...
On linux kali. I got an Atheros wireless adapater. I'm trying to capture data packets off the air and decypt them as an excerise. I apologize if this question is silly. The problem is that when I turn on the wifi monitor mode and choose a...
I've been coding and using Linux and networking for two decades now, and I would consider my knowledge in networking mostly advanced. But the danger with knowledge is that we never know what we don't know, yet we can sometimes give ourselv...
I'm a data science student who is working on a machine learning security solution for IoT devices.
I will be using Cooja simulator (under Contiki OS) to deploy the model and test it, I have no idea how to acheive this, couldn't find tutori...
So my question is along these lines:
Configuring a network for 100% isolation (for security)
My goal: plug any device into a switch or router and no other (non-networking-infrastructure) device knows of it's presence or can communicate wi...
I make "embedded" electronics and often they are connected to Wi-Fi. For a battery powered applications, in order to save power, a common strategy is power down as often and for as long as it is possible to do so. In one product ...
