re: Report: Unauthorized Apps Run Rampant on Many Enterprise Networks
Regarding Tor in the workplace: -Good luck with that! -:)

Usage scenario: -Tunnelier Portable (SSH tunneler application) configured with port forwarding. -

1. user configures SSH profile.
2. user configures Client-to-Server port forwarding rules allowing connections to services they run on the remote network so that they don't have to run them locally where they'll inevitably be detected.
3. user configures Firefox Portable, KVirc Portable, and a few other portable apps to connect via HTTP/HTTPS proxy on 127.0.0.1:8118 (which is forwarded to a Privoxy + TOR + I2P proxy construct at the remote location).
4. user accesses darknet domains freely, and IT has no (or limited) ability to block or circumvent this activity.

In an alternate scenario, the user utilizes a similar construct via a Linux PC configured with GSTM (Gnome Secure Tunnel Manager) to do basically the same thing.

Personally, I've explored this option very heavily and it works fantastically to circumvent any and all network traffic filtering put in place on the corporate network, effectively allowing the user to do as they please... albeit at a reduced speed due to the overhead of the SSH-to-Privoxy-to-Tor-Tunnel... but with broadband availability being what it is today, the speed of Tor is increasing all the time, making it a much more attractive option to those that are in the know. -Since Tunnelier only makes a single connection, which it keeps alive and wraps in AES256 encryption via SSH2 protocol, and OpenSSH can be configured to listen on literally any TCP port, it's *nearly* impossible to detect and block, since it can simply be tunneled in turn over HTTPS.

What many security articles overlook, although this one hints at, is the fact that many savvy corporate network users are using hacking skills themselves, but not to hack in.... rather, to hack *out*, essentially giving them freedom of movement to external networks and resources.

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.
