After all, a breach at Slack, a phished co-worker, or a rogue insider can't hurt you with words you never typed in the first place. Think about what you're typing, where you're typing it, and the permanent nature of your words. "If you're a client of mine," Lyons says, "I can give you a guest account to one channel and you can't see anything else, and it will expire in one month or two months or whatever I set it for."Įncryption is great for securing messages but it can't fix human nature. Use guest accounts for contractors or users who need limited access for a shorter period of time. Don't set the session to be too short, though, Lyons warns, as users will find this very annoying, especially on mobile. Setting automatic session logouts, instead of the infinite login sessions Slack allows, can help weed out inactive accounts. Five hundred employees on an internal Slack channel might as well be writ large in the clouds for all the world to see. The fewer people who have access to sensitive information, the less likely it is to leak. Disenroll inactive members or employees after a set period of time. Be selective about who you allow to join Slack channels. The human element: Choose Slack participants wisely Keep Slack and email separate whenever possible.
One of the big advantages of Slack is that it's far more usable than CC'ing dozens of people in an email.

Users can turn off this default, and admins can enforce this setting in higher paid tiers. Every mention of a user in a Slack channel goes to the user's email inbox or appears as a push notification by default. If you're worried about the confidentiality of your Slack workspaces, turn off Slack email notifications. Organizations that choose to accept the elevated risk to their Slack workspaces to gain a slight productivity advantange should do so with eyes open, aware of the risks. The network effects of integrating multiple work tools means that a flaw in any of them affects the security of all of them. "If I'm talking to you and you have a bunch of crazy integrations, then that's affecting my conversation with you," Lyons says.

"Such tokens can provide access to chats, files, private messages, and other sensitive data shared inside the Slack teams where those developers or bots are members," our colleague at PC World reported at the time.
In 2016, more than 1500 Slack access tokens, hard-coded into open source projects, were discovered on GitHub. Remove them unless you absolutely must have them. Although Slack reviews all third-party apps for appropriate permissions and data access, every additional integration increases the overall attack surface to your organization.
