Row-Level Security (RLS) and Column-Level Security (CLS) are methods that simplify the design and coding of security in applications by imposing restrictions on data access. CLS allows for specific users to access only certain columns of a table relevant to their department, protecting sensitive data. RLS, on the other hand, restricts users to accessing only data rows pertinent to their role or department. Both methods locate the access restriction logic in the database tier, applying the restrictions every time data access is attempted from any tier, making the security system more reliable and robust.
