In this lesson,
we will learn about role-based access control, or RBAC.
Role-based access control manages user access
by assigning permissions based on the user's role
within an organization.
Role-based access control
is implemented by defining roles within an organization
and associating specific permissions With each role.
Users are then assigned to roles
and their access rights are inherited from the role
they are assigned to.
Let's learn more about role-based access control.
Role-based access control, or RBAC
allows administrators to assign users to specific roles,
and those roles determine
what resources the user can access.
So, instead of giving individual permissions to each user,
you create roles that represent job functions
and assign permissions to those roles.
Then users are added to the roles
that match their responsibilities.
This makes managing access simpler and more organized,
especially in larger organizations.
In a Windows enterprise environment
role-based access control is typically implemented
using active directory groups.
You first create groups in active directory
that represent roles within the organization,
such as HR for Human Resources, Finance, or IT support.
Then you assign permissions to those groups
based on the resources they need.
For example, the HR group
might have access to employee records,
while the finance group has access to financial records.
To implement role-based access control,
you would then add each user
to the group that matches their role.
If someone changes roles or leaves the company,
all you need to do is update their group membership
and their access will automatically be adjusted.
In a Linux enterprise environment
role-based access control
can be implemented using Linux user groups.
Just like in Windows, you create groups
that represent roles within the organization.
For example, you might create groups like Admins
or Developers or Sales.
Then you assign permissions to those groups
for specific directories or files using Linux permissions.
For instance, the developer's group might have write access
to the source code directories,
while the sales group has only read access to sales reports.
You would then add users to the appropriate groups
to give them the permissions that they need.
This way, when a user joins the company
or moves to a new role,
you can simply modify their group memberships
to update their access.
So remember,
role-based access control or RBAC
manages access by assigning users to roles
that define their permissions within an organization.
Administrators create roles based on job functions
and link them to specific permissions for resources.
Users are then assigned to these roles,
which simplifies access management and ensures consistency.
This approach makes it easier
to update permissions as roles change,
especially in larger organizations.
