Reino: Security Features
La seguridad de un software no es un software de seguridad. Nos preocupamos de cuestiones como la autenticación, el control de acceso, la confidencialidad, la criptografía y la gestión de privilegios.
Privilege Management: Overly Broad Access Specifier
Abstract
El código privilegiado de los métodos
public se pueden llamar desde cualquier parte del JVM.Explanation
Los principios de codificación segura abogan por hacer que los especificadores de acceso sean tan restrictivos como sea posible. Un método con un especificador de acceso
Ejemplo 1: en el código siguiente,
public indica que todo el código externo tiene permiso para llamarlo. Los métodos públicos que realizan acciones privilegiadas pueden ser peligrosos cuando el código se comparte en bibliotecas o en entornos donde el código puede entrar de forma dinámica en el sistema (por ejemplo, inserción de código, inclusión de archivos peligrosos, carga de archivos, etc.).Ejemplo 1: en el código siguiente,
doPrivilegedOpenFile() se declara public y realiza una operación privilegiada.
public static void doPrivilegedOpenFile(final String filePath) {
final BadFileNamePrivilegedAction pa = new BadFileNamePrivilegedAction(filePath);
FileInputStream fis = null;
...
fis = (FileInputStream)AccessController.doPrivileged(pa);
...
}
