Este es uno de los últimos libros que acabo de consultar, su tema principal es la seguridad y está dirigido a lectores con un nivel básico (por ejemplo presenta una explicación sencilla de como funcionan servicios como DNS, LDAP o tecnologías como Cliente/Servidor) pero al mismo tiempo es bastante completo cubriendo muchos aspectos.

El libro está dividido en cinco partes:
1.Principos de seguridad
2. Sistemas operativos y aplicaciones
3. Fundamentos de la seguridad en redes.
4. Comunicaciones
5. Amenazas de seguridad y respuestas

Uno de sus mayores inconvenientes es que en algunas ocasiones (aunque no muchas) se centra en la normativa de los Estados Unidos. Presenta sin embargo algunos conceptos interesantes por ejemplo, aquí están alguna de las notas que he tomado:

1. Las diferencias entre el plan de contingencias, el plan de recuperación ante desastres, el plan de continuidad de operaciones y el plan de continuidad del negocio:

• Contingency plan — The documented, organized plan for emergency response, backup operations, and recovery maintained by an activity as part of its security program that will ensure the availability of critical resources and facilitates the continuity of operations in an emergency situation.
• Disaster recovery plan — The plan and procedures that have been developed to recover from a disaster that has interfered with the network and other information system operations.
• Continuity of operations plan — The plans and procedures documented to ensure continued critical operations during any period where normal operations are impossible.
• Business continuity plan — The plan and procedures developed that identify and prioritize the critical business functions that must be preserved and the associated procedures for continued operations of those critical business functions.

2. Las diferencias entre un cold site, un warm site y un hot site cuando hablamos de bakups.

3. Al hablar de biométrica distingue los conceptos de :

• False rejection rate (FRR) — The percentage of valid subjects that are falsely rejected
• False acceptance rate (FAR) — The percentage of invalid subjects that are falsely accepted
• Crossover error rate (CER) — The percent in which the FRR equals the FAR

4. Una lista de los servicios no tan habituales en linux como:

• anacron — This service is an enhanced cron replacement It can run jobs that were scheduled for execution while the computer was turned off.
• atd — This service runs scheduled batch jobs.
• autofs — This service auto mounts file systems on demand.
• arpwatch — This service is used to construct and monitor an ARP table, which keeps track of IP address-to-MAC address pairings.
• apmd — This is the advanced power management daemon, primarily used on laptops and other battery-backed devices. The apmd daemon senses the hardware and suspends or shuts down the workstation or laptop.
• crond — This service is used to schedule jobs for later execution. Many sytem administrator tasks can be run with cron. If this can’t be disabled, autho rization to run cron jobs should be limited to a few users.
• gpm — This service is the text-mode cut-and-paste daemon. This service has been a source of security concerns and performance problems in the past.
• innd — This service is the INternet News System (INN) news server. Normally this is run on a server and not a workstation.
• nscd — This service provides password and group lookup services for use with network authentication such as that used in Lightweight Directory Access Protocol (LDAP)

También ofrece algunas tablas resumen muy interesantes sobre el ancho de banda de las tecnologías celulares e inalámbricas.
