ISECOM, the renowned research organization for security, has again “made sense” of securing a Linux network against attacks. The book is a thorough guide to understanding how to “separate the asset from the threat” and block hackers from playing in the ultimate playground of Linux.  The authors take you from the elements of security, to hacking the system, to hacking the users. 

What is particularly helpful are the case studies. If you or your company’s employees need to travel and access your company’s website via wireless connection, you’ll be especially interested in the case study in Chapter Eight, where a hacker tracks a signal to a hotel’s access point and creates legit-looking error pages in order to obtain the account information of the user. Also helpful are their usual attack and countermeasure icons, which further define how to pinpoint areas of risk.

Security teams looking to evaluate their areas of vulnerability within Linux will be forearmed with the powerful arsenal of preventative approaches covered in this edition. All of the material is new, based upon the most recent and thorough security research. The hacking and countermeasure are based on the OSSTMM, the security testing standard, and cover all known attacks on Linux as well as how to prepare the system to repel unknown attacks. A pretty good buy for the $49.95 cost.
