You've managed to get your Slack team off the ground and
are happy with the team's communication flow. Then, one of your colleagues
decides to share a sensitive document containing information about their
research project on Slack.
Judging by how quickly Slack has become an integral part of
some workplace conversations, it would be easy to assume that sharing sensitive
documents on this platform is nothing out of the ordinary.
Still, there are quite a few Slack data security concerns you should keep
an eye out for. That's why we're diving into these concerns as well as how you
can handle them.
Employee and Guest User Onboarding
One of the biggest security concerns any Slack account user
has to deal with is how to effectively onboard employees and guest users on
Slack.
What we mean by this is how do you best ensure that you've
got full control of your company's Slack account without the risk of opening it
up to the wrong people?
The answer here lies within your Slack account's access
controls.
For instance, if you want to allow multiple team members to
have access to a shared channel, but only if they're contributing to a
particular project, then you'll want to make sure that only those people can
access that channel.
Fortunately, if you've got your team members or users
hooked up to your Slack authentication app, you don't have to worry about
onboarding as long as you've got a Slack admin (or administrator) who can take
care of the rest.
Onboarding a guest user at this point is just a matter of
adding them to the guest list and delegating them with specific permissions. As
far as those people go, you can't do anything about them accessing Slack until
now.
Interestingly enough, this is also one of the most
overlooked aspects when it comes to Slack data security, particularly from the
guest's side. It doesn't matter how good your guest user onboarding app is if
you aren't doing a good job in protecting the sensitive data you're sharing
with your guest users on Slack.
To make sure guests and user don't overstay their welcome,
cut off access immediately after they're no longer needed. Also, you can always
review the access logs to make sure no one is overstaying their welcome.
Owner and Admin Access Rights
Another Slack data security concern any company should be
aware of is the issue of accessing shared channels.
Take, for instance, giving an admin ultimate access to
creating, sharing, and deleting groups or users from your workspace. This has
its benefits, but it also has its risks, particularly when the wrong person
gets ahold of these admin rights.
To mitigate this risk, you'll want to be careful in
assigning permissions. For example, instead of giving one person access to all
your Slack account's shared channels, you should just give them access to the
specific channel(s) they need to get the job done.
The best part about regular reviews is that you'll be able
to keep track of how much access each team member needs or doesn't need. You'll
just have to keep tabs on these changes so that you don't end up sharing
sensitive data with the wrong people.
On top of these, there are also small tweaks you can do to
help prevent Slack data security issues such as installing the Two-Factor Authentication for Slack and
disabling direct messages from certain guests and users.
Third-Party Integrations
Despite its versatility, Slack is still a platform that has
a lot of room for third-party integration. Unfortunately, this also makes Slack
one of the top places for cybercriminals to target.
For instance, if you're not careful about making sure
you're installing the right apps—or any apps at
all—onto your Slack account and workspace, you could be putting your company's
security at risk.
We recommend doing a thorough security audit of all
third-party apps you add to your Slack account and workspace. This will ensure
that you're only trusting and installing safe apps.
You should also be cautious about who has access to these
integrations as well. For instance, instead of giving every two-factor
authentication app or password manager access to your entire Slack account,
it'll be a good idea to give them only the permissions they need on their own
accounts.
Improving Your Slack Security
There are a few more things you can do to keep your Slack
account and workspace secure. For instance, we recommend mounting a two-factor
authentication app on Slack as this gives you extra security for accessing your
account.
Similarly, you should also limit how much of your sensitive data is shared with external users
or guest users. You can do this by limiting the number of external and guest
users you invite to Slack or by removing their access to shared channels as
soon as they're no longer needed.
Either Way, Slack is still a great platform for organizing
team conversations and a great place for you to communicate with your
employees, colleagues, and partners.
However, there are still ways you can improve your security
settings so that Slack is nothing but a fun place for you and your colleagues
to talk about the latest game of ping pong.
