More about access control policies

Overview

When working in teams or with external partners, controlling access to your application’s configuration files is just as important as controlling access to your code or your infrastructure.

Skycap Policies give you fine-grained control over both who can access your Stencils and Formations, and what those people can do with their access (e.g. read-only).

Advanced use cases

Apart from the obvious use cases, such as limiting the access of external contractors or junior staff members, Skycap Policies allows you to:

Access control principles

Access and permissions policies in Skycap are additive and positive. In other words they work by granting access and permissions to users, not by excluding access.

So if a user needs access to something, you will grant them access to that component (or set of components) which will not affect their access (or lack thereof) to any other components.

Hierarchy and inheritance

Permissions are hierarchical and have cascading inheritance. For example if you have access to a Formation and there are no permissions set for the Stencils within that Formation, you will by extension also have the same kind of permissions on those Stencils.

In general if there are two or more levels of restriction in place, the “stricter” and more specific rule will be used. For example if you grant someone full access to a Formation but read-only access to the Stencils within that Formation, they will not be able to edit them.

Warning

Unless you specify an access policy for your Formations and/or Stencils, any team members with “Developer” level (or above) access to your application will, by default, have full permissions on all of the Formations for that application.

Levels of access control

Skycap offers several different tiers of access to cater for teams and applications of different sizes and complexities:

Formations

You can control whether users can access an entire Formations at three levels:

  1. Access to a specific (single) Formation within a specific application
  2. Access to all the Formations within a specific application
  3. Access to all Formations across all your applications

Stencils

You can also control whether users can access the Stencils within your Formations. This has four levels:

  1. Access to a specific (single) Stencil within a specific Formation
  2. Access to all the Stencils within a specific Formation
  3. Access to all the Stencils in all your Formations for a specific application
  4. Access to all the Stencils in all your Formations for all your applications

Warning

These access control settings allow for a degree of overlap. For example level 4 access to Stencils is very similar to level 3 access to Formations. Be cautious when assigning higher levels of access.

Assigning Permissions

You can control the permissions per user at any of the levels described above. You can allow users to perform any combination of the following actions within the specified Formation:

The available permissions within Stencils are:
