ERROR_NO_SECURITY_ON_OBJECT - 1350 (0x546)
Unable to perform a security operation on an object that has no associated security.
Updated: Feb 21, 2026
Technical Meaning
The ERROR_NO_SECURITY_ON_OBJECT error, with the numeric code 1350 and hexadecimal representation 0x546, signifies that a security-related operation was attempted on an object that does not have any associated security information. This typically means that the object lacks necessary permissions or access control lists (ACLs) required for performing certain operations.
Error Details
This error is returned when a function or API call requires security context to be established, but the target object does not possess such context. Common scenarios where this might occur include attempts to modify ACLs, set ownership, or perform other security-sensitive actions on an object that has no defined security descriptor.
Usage Context
The error is relevant in contexts where security operations are expected, such as modifying file permissions, changing directory access controls, or setting ownership. It indicates that the operation cannot proceed without a valid security context for the target object.
Developer Interpretation
When encountering this error, developers should ensure that the objects being manipulated have appropriate security descriptors and that the necessary privileges are available to perform the required operations. This might involve verifying the existence of ACLs or ensuring that the process has sufficient permissions to modify the object's security settings.

A: It indicates that a security operation cannot be performed on an object because it lacks associated security information.
Q: How can I resolve this issue?
A: Ensure that the target object has appropriate security descriptors and verify that the process has sufficient privileges to modify its security settings.
Summary
The ERROR_NO_SECURITY_ON_OBJECT error is a generic indication of an attempt to perform a security operation on an object without proper security context. Developers should ensure that objects have valid security descriptors and that processes possess necessary permissions to avoid this issue.
