How has the US Supreme Court upheld a restriction on family visitation of a sentenced prisoner for "security reasons"?

The Government also cites cases where interference with the right to family integrity was upheld in furtherance of identified safety or other penological interests. See, e.g., Overton v. Bazzetta , 539 U.S. 126, 133, 123 S.Ct. 2162, 156 L.Ed.2d 162 (2003) (upholding restrictions on family visitation of sentenced prisoners for security reasons and "to protect[ ] child visitors from exposure to sexual or other misconduct[.]"). However, Plaintiffs argue the Government is acting without determining parentage, fitness or danger to the child (or any other legitimate reason), let alone for a stated security reason.
