What is the SSH agent?Open Keychain Access for me. IвЂ™ll help you reduce your risk when using agent forwarding, and IвЂ™ll share an alternative to agent forwarding that you can use when accessing your internal hosts through bastions. IвЂ™ll also describe agent forwarding and how it works. In this post, IвЂ™ll explain what the agent is, how to use it, and how it works to keep your keys safe.

It holds your keys and certificates in memory, unencrypted, and ready for use by ssh. To override the trust policies, choose new trust settings from the pop-up menus.Ssh-agent is a key manager for SSH. Next to Trust, click the arrow to display the trust policies for the certificate.

It doesnвЂ™t write any key material to disk. With OpenSC you can use many smart cards on Linux, Mac OS X and. 509 certificate based user login. Danberry Last Review: 07 October 2015 Adding these certificates are normally not needed, however, if you are using CITRIX on your Mac or your new CAC has a CA of 27-32, you may need these for your computer to communicate with some websites.The SSH agent keeps private keys safe because of what it doesnвЂ™t do:Compile and install OpenSC smart card reader software 2. In order for your machine to recognize your CAC certificates and DoD websites as trusted, the installer will load the DoD CA certificates on OS X.Adding DoD certificates to your Mac Presented by: Timothy Solberg and Michael J. It runs in the background on your system, separately from ssh, and it usually starts up the first time you run ssh after a reboot.Download and install the OS X Smartcard Services package The OS X Smartcard Services Package allows a Mac to read and communicate with a smart card.

When you run ssh-add without any parameters, it will scan your home directory for some standard keys and add them to your agent. It performs all of these operations except for signing. Lock or unlock the entire agent with a passphraseрџ¤” WhatвЂ™s a constrained key? ItвЂ™s usually a key that either has a limited lifetime or one that demands explicit user confirmation when it is used.The ssh-add command is your gateway to the SSH agent. Sign a message with a key stored in the agent

To store key passphrases in the Keychain, run ssh-add -K. Depending on your Keychain settings, you still may need to unlock the keychain after a reboot. Ssh-agent and the macOS KeychainThe ssh-agent that ships with macOS can store the passphrase for keys in the macOS Keychain, which makes it even easier to re-add keys to the agent after a reboot.

How agent forwarding worksFirst, a little background. With agent forwarding, the SSH client on EC2 can use the keys on your local computer to authenticate to GitHub. Without agent forwarding, youвЂ™d have to store a copy of your GitHub private key on the EC2 host. For example, say you SSH into an EC2 instance, and you want to clone a private GitHub repository from there. What is agent forwarding?SSHвЂ™s agent forwarding feature allows your local SSH agent to reach through an existing SSH connection and transparently authenticate on a more distant server. Ssh-agent will use these stored passphrases automatically as needed.

They can use your keys to impersonate you on other machines on the network.HereвЂ™s an example of how that might look:How to reduce your risk when agent forwardingHere are a few ways to make agent forwarding safer:Many guides on agent forwarding will suggest turning on ForwardAgent using the following configuration: Host example.comWe suggest not doing that. When you connect to a remote host with agent forwarding enabled, SSHD will create a remote Unix domain socket linked to the agent forwarding channel, and export an $SSH_AUTH_SOCK pointing to it.When you forward ssh-agentвЂ™s Unix domain socket to a remote host, it creates a security risk: anyone with root access on the remote host can discreetly access your local SSH agent through the socket. SSH always looks at the $SSH_AUTH_SOCK environment variable to find the Unix domain socket for the agent. When agent forwarding is enabled for a connection (usually using ssh -A), a second channel is opened up in the background to forward any agent requests back to your local machine.From sshвЂ™s perspective, there is no difference between a remote and a local ssh-agent. HereвЂ™s a common example: an interactive connection to a bastion host (jump box) runs on one channel.

If youвЂ™re trying to access internal hosts through a bastion, ProxyJump is a much safer alternative for this use case. Sekey uses Touch ID on macOS to store keys in the MacBook ProвЂ™s security enclave.Or donвЂ™t use agent forwarding at all. When youвЂ™re connected to a remote host with agent forwarding, no one will be able to snake their way into your agent without the password.Or use an alternative SSH agent that prompts you when itвЂ™s being used. Ssh-add -x locks the agent with a password, and ssh-add -X unlocks it. Ssh -A turns on agent forwarding for a single session.Lock your ssh agent when you use agent forwarding.

Cloud.computer.internal is a hostname that can be looked up using DNS lookup on bastion.example.com. Run ssh -J bastion.example.com cloud.computer.internal to connect to cloud.computer.internal via your bastion.example.com bastion host. A better approach is to use the ProxyJump directive.Instead of forwarding the agent through a separate channel, ProxyJump forwards the standard input and output of your local SSH client through the bastion and on to the remote host.
