The SANS Institute
The SANS (Systems Administration, Networking, and Security) Institute sponsors the Global Information Assurance Certification (GIAC) program, a series of security certifications that have a more technical, hands-on focus than the CISSP certification. GIAC is an excellent complement to CISSP certification, and SANS offers a 40-percent discount on its GSEC (GIAC Security Essentials Certification) certification for those who have CISSP certification.
This website also includes SANS conference schedules, an extremely helpful “Internet Storm Center” and security digest, the SANS online bookstore, various projects, resources, security links, sample security policies, white papers, GIAC student practicals, and security tools.
The site also features the SANS/FBI Top Twenty Vulnerabilities list. This list, co-sponsored by the FBI, helps organizations prioritize security efforts by listing and describing the top 20 Internet security vulnerabilities in three categories: General Vulnerabilities, Windows Vulnerabilities, and UNIX Vulnerabilities.
