Detectando Malicia, en inglés Detecting Malice, es un libro escrito por Robert "RSnake" Hansen (ha.ckers.org) para ayudar a los administradores web, los desarrolladores, el personal de operaciones y los managers de productos de seguridad en la construcción y el mantenimiento de un estado de seguridad elevado.
La comprensión de la intención del usuario es la clave para reducir los ratios de fraude en las aplicaciones web modernas. Desde pymes al gobierno, este libro abarca muchos ámbitos diferentes de fraude y cómo detectarlo en muchas capas diferentes.
Desde DNS y TCP al contenido embebido y el fingerprinting del navegador se utilizan para identificar a los usuarios que tienen más probabilidades de llegar a ser peligrosos antes de que el ataque suceda. Una gran cantidad de técnicas y ejemplos están disponibles en las más de 300 páginas de este interesante libro.
