PowerShell+ 2019 - Firewall Evasion and Remote Access with OpenSSH by Anthony Nocentino
0OpenSSH is much more than just remote terminal access to servers, it provides a full suite of remote connectivity methods to your network and its services. In this session, we will look at how to use OpenSSH and its forwarding, tunneling and VPN capabilities so that we can reach securely reach network services that are behind firewalls and other security boundaries. Common use cases for these techniques are cloud jump boxes, secure access into segmented networks and being able to get remote access and move data around in poorly secured networks....these tips are things that will likely get you some extra attention from your security team
* We will look at the following techniques
* Accessing remote application services with SSH Tunneling
* Accessing remote networks with SSH-based VPN
* Building SSH connections for multi-hop remote access using ProxyHosts
* Proxying HTTP/HTTPS connections with SocksProxy
* Using aliases to store these advanced configurations for easy use
* Controlling and preventing TCP tunneling
PowerShell Summit videos are recorded on a "best effort" basis. We use a room mic to capture as much room audio as possible, with an emphasis on capturing the speaker. Our recordings are made in a way that minimizes overhead for our speakers and interruptions to our live audience. These recordings are meant to preserve the presentations' information for posterity, and are not intended to be a substitute for attending the Summit in person. These recordings are not intended as professional video training products. We hope you find these videos useful - the equipment used to record these was purchased using generous donations from members of the PowerShell community.
