How are object and field permissions enforced in apex?
Apex generally runs in system context; that is, the current user’s permissions and field-level security aren’t taken into account during code execution. Sharing rules, however, are not always bypassed: the class must be declared with the without sharing keyword in order to ensure that sharing rules are not enforced.
What does it mean to have access to all objects in apex?
In this mode, Apex code has access to all objects and fields, and the sharing rules are not applied for the current user. This guarantees that the code will work regardless of the fact whether a user that executes Apex code has access to the objects and their fields.
How to find out if a user has edit access to a record?
To find out if a particular user has Edit access to a record, use the UserRecordAccess object. This object is available in API version 24.0 and later. You can use SOQL to query this object to find out if the user has edit access to the record in question. But make sure that allRecordIds is a LIST of IDs.
Can you set an apex class to run?
However, to make sure that confidential data is not accessible for users that are not supposed to have access to it, you can set an Apex class to be run considering the privileges, sharing rules, levels of access to the fields by the user, under whose name the class was launched. This can impact SOQL, SOSL, and DML expressions.
Why is apex not using with sharing keywords?
Apex code is mostly run in system context so it is not considering current user’s permission. It is creating data integrity issue. Using with sharing keywords when declaring a class enforces Sharing Rules, but not object and field-level permissions.
When to use with security enforced in apex?
Use the WITH SECURITY_ENFORCED clause to enable field- and object-level security permissions checking for SOQL SELECT queries in Apex code, including subqueries and cross-object relationships. Apex generally runs in system context; that is, the current user’s permissions and field-level security aren’t taken into account during code execution.
How to enforce object and field level permissions?
Using with sharing keywords when declaring a class enforces Sharing Rules, but not object and field-level permissions. In Spring 20 release some security enhancements are added to enforce object and field-level permissions. We can now use Schema.DescribeFieldResult to check current user has read, create, or update access for a field.
