Re: Assessment Tools
It does, thanks!

What would you recommend for something where you have little control such as the unencrypted smart tv? What are the mitigation options?

Re: Assessment Tools
Ryan, thank you for your comment.

 

I did not really use any tools in that way. The only "tools" i used where nmap, telnet, netcat, perl, python and my web browser with the "Live HTTP headers" extension installed.

During the audit i developed my own tools on a regular basis to automate some of the tests i wanted to perform. I personally do not have strong faith in the open source "hacking" tools. When you want to audit large networks, they might be useful. but when you only have a handful of devices, its much better with a minimalistic approach.

I am pretty sure any vulnerabiluty scanner would jum pof the roof when it comes to missing security patches, but remember, all the vulnerabilities i discovered were new, and had not been discovered before. Then these tools such as Nessus, does not really work.

 

I hope this helps:)

Re: Assessment Tools & Lock down
Hi Marilyn,


Thank you for your comments... Well what do you mean with "lock down" my home network. Once one of the devices which were on my local network, i could have performed various attacks to make the network unaccessible, such as DoS attacks.


I could also have deleted all the data on the storage device, and i mean ALL data, i could have crashed the entire device, probably same thing for the other devices such as TV. Due to the cost of the device, i did not want to do that :) And i did not want to explain for the kids why the TV was broken :)

Re: Assessment Tools & Lock down
David , were you able to lock down your home network -- or any part of it? Also please keep us posted on what you hear back from vendors about their efforts on developing patches .

Assessment Tools
Interesting article.

What tools did you use to discover the vulnerabilities. (Kismet, nessus, etc) And when performing the tests, did you take the mindset of an attacker? Meaning treating this as if you had no inner intel or did you do this as a how am I vulnerable from each vector that is already known to the home owner?

I think these are important tests for anyone to run. Also, we need to ingrain security from the development stage. This comment is directed at the non-encrypted data transit from the smart tv. If we don't make this a priority as the consumer than organizations may be reluctant to change.

Improving Enterprise Cybersecurity With XDR
Enterprises are looking at eXtended Detection and Response technologies to improve their abilities to detect, and respond to, threats. While endpoint detection and response is not new to enterprise security, organizations have to improve network visibility, expand data collection and expand threat hunting capabilites if they want their XDR deployments to succeed. This issue of Tech Insights also includes: a market overview for XDR from Omdia, questions to ask before deploying XDR, and an XDR primer.
