Los tres pilares (La Tr\u00edada CIA)<\/span><\/h3><p data-path-to-node=\"5\">Para que una red sea segura, debe cumplir con tres cosas:<\/p><ul data-path-to-node=\"6\"><li><p data-path-to-node=\"6,0,0\"><b data-path-to-node=\"6,0,0\" data-index-in-node=\"0\">Confidencialidad:<\/b> Que solo las personas autorizadas vean la informaci\u00f3n (que nadie \u00abesp\u00ede\u00bb).<\/p><\/li><li><p data-path-to-node=\"6,1,0\"><b data-path-to-node=\"6,1,0\" data-index-in-node=\"0\">Integridad:<\/b> Que la informaci\u00f3n no sea alterada en el camino (que el mensaje llegue tal cual se envi\u00f3).<\/p><\/li><li><p data-path-to-node=\"6,2,0\"><b data-path-to-node=\"6,2,0\" data-index-in-node=\"0\">Disponibilidad:<\/b> Que la red y los datos est\u00e9n listos para usarse cuando se necesiten (que no se caiga el sistema).<\/p><\/li><\/ul><h3 data-path-to-node=\"7\"><span style=\"color: #00ccff;\">2. Herramientas b\u00e1sicas de defensa<\/span><\/h3><p data-path-to-node=\"8\">Imagina que tu red tiene diferentes capas de protecci\u00f3n:<\/p><p data-path-to-node=\"9\">El Firewall (Cortafuegos)<\/p><p data-path-to-node=\"10\">Es el \u00abguardia de seguridad\u00bb en la entrada. Revisa qui\u00e9n entra y qui\u00e9n sale de la red bas\u00e1ndose en un libro de reglas. Si algo parece sospechoso, le niega el paso.<\/p><p data-path-to-node=\"11\">El Cifrado (Encriptaci\u00f3n)<\/p><p data-path-to-node=\"12\">Es como escribir un mensaje en un c\u00f3digo secreto. Si un hacker intercepta tus datos, solo ver\u00e1 s\u00edmbolos sin sentido. Solo el destinatario tiene la \u00abllave\u00bb para traducir el c\u00f3digo y leer el mensaje original.<\/p><p data-path-to-node=\"13\">VPN (Red Privada Virtual)<\/p><p data-path-to-node=\"14\">Crea un \u00abt\u00fanel privado\u00bb y seguro dentro de la selva p\u00fablica que es Internet. Es ideal para cuando te conectas desde un caf\u00e9 o un aeropuerto, ya que oculta tu actividad.<\/p><hr data-path-to-node=\"15\" \/><h3 data-path-to-node=\"16\"><span style=\"color: #00ccff;\">3.
