What are two main security best practices in Sitecore?

The correct answer highlights two important practices in Sitecore security management. Setting security on every user can lead to complications in permissions and necessary maintenance as user roles and responsibilities change frequently. By avoiding explicit denies, you ensure that a user does not inadvertently lose access to necessary content, which could happen if rights are misconfigured.

Managing security primarily through roles rather than individual users simplifies the process of permission management. Roles offer a way to group users and apply permissions collectively, which is easier to maintain and scalable as the organization grows.

On the other hand, using default rights without custom roles might limit the flexibility required for specific user access scenarios. While it’s often easier to apply standard configurations, custom roles can address unique operational needs that default settings cannot fulfill. Therefore, focusing on users instead of roles for security can lead to unnecessary complexity and oversight.
