UNDERSTANDING THE BASICS OF ACCESS CONTROL

TYPES OF ACCESS CONTROL

1) Discretionary Access Control (DAC) : This type allows the owner of the information or any object to regulate who can access specific resources. For instance, a project manager could have the discretion to determine which team members can access certain project documents.

2) Mandatory Access Control (MAC) : Under MAC, access permissions are assigned based on regulations or policies. This is often seen in organizations with highly classified or sensitive information.

3) Role-based Access Control (RBAC) : Here, access permissions are granted according to roles within the organization. 

For example, a Sales executive might have access to sales records but not to financial data.

PRINCIPLES OF ACCESS CONTROL

1) Least Privilege : This principle suggests granting only the bare minimum permissions necessary for users to accomplish their tasks. It helps in minimizing potential damage in case of accidental mishaps or intentional malfeasance.

2) Separation of Duties : By dividing tasks and privileges among multiple people or systems, this principle helps prevent fraud and errors.

3) Need to Know : Access to information should be granted only if it’s necessary for individuals to perform their duties.

EXPLORING USER GROUPS

BENEFITS OF USER GROUPS

1) Streamline Permission Management : By organizing users into groups, administrators can manage permissions efficiently, reducing the overhead of managing permissions individually.

2) Enhanced Security : Groups provide a way to easily update access rights for multiple users at once, which is especially useful in case of role changes or departures.

3) Consistent Permissions : Ensures that all users with similar roles have the same access rights, promoting consistency across the organization.

CREATING AND MANAGING USER GROUPS 

• Navigate to Settings > Users > Groups in Odoo 17.
• Click on the “Create” button to create a new user group.
• Enter a name for the group and under the ‘Access Rights’ tab, you can specify the access rights for this group.
• Click on the “Save” button to save this group.

DELVING INTO ACCESS RIGHTS 

TYPES OF ACCESS RIGHTS

• Read : This allows users to view the information but not make any changes.
• Write : Users can modify the information.
• Create : Users have the privilege to create new entries or objects.
• Delete : This allows users to remove entries or objects.

ASSIGNING ACCESS RIGHTS

• Navigate to the user group’s form, select the “Access Rights” tab.
• Here, you can tick the checkboxes next to the respective access rights you wish to grant to this group.
• Click on the “Save” button to apply these rights.

UNDERSTANDING RECORD RULES

PURPOSE OF RECORD RULES

Record rules provide a mechanism to define access control at a record level, allowing for a fine-grained control.

These rules can be used to restrict access to specific records based on certain criteria, ensuring that only authorized personnel can access or modify them.

CREATING AND MANAGING RECORD RULES

• Navigate to Settings > Technical > Record Rules.
• Click on the “Create” button, select the model for which you want to create a record rule.
• Enter a domain expression to define the criteria for access and save your settings.

Example :

python
model = ‘sale.order’
domain = [(‘amount_total’, ‘>’, 10000)]
groups = [(‘ref’, ‘=’, ‘sales.group_sale_manager’)]

In this example, only members of the “Sales Manager” group can access sales orders with a total amount greater than $10,000.

UTILIZING SECURITY GROUPS

BENEFITS OF SECURITY GROUPS

Additional Security Layer : Security Groups add an extra layer of security by allowing restrictions based on various criteria like IP addresses.

Prevent Unauthorized Access : They help in preventing unauthorized access to sensitive information by ensuring only authorized personnel can access certain data based on predefined criteria.

CREATING AND MANAGING SECURITY GROUPS

• Navigate to Settings > Technical > Security Groups.
• Click on the “Create” button, enter a name for the security group, define the criteria for membership, and save your settings.
