What security setting should they implement to achieve this?

An organization using Slack needs to ensure that their workspace can only be accessed from their office premises for security reasons.

What security setting should they implement to achieve this?
A . Two-factor authentication for all user logins
B . IP whitelisting to restrict access to the office network
C . Requiring all communications to be in private channels
D . Frequent mandatory password changes for all users

Answer: B

Explanation:

IP whitelisting to restrict access to the office network IP whitelisting is the most effective measure to ensure that Slack can only be accessed from the organization’s office premises, as it allows access only from specific, pre-approved IP addresses.

Option A is incorrect because two-factor authentication, while providing additional security, does not restrict access based on location.

Option C is incorrect as communicating in private channels does not restrict the physical location from which Slack can be accessed.

Option D is incorrect because frequent password changes enhance account security but do not control the location of access.
