Another great resource is the Global Information Assurance Certification (GIAC) Security Expert designation, offered by the SANS Institute. The institute is widely recognised as an industry resource for security professionals not only for their certifications but also training, research, education and books.
While there are numerous niche security certifications including malware analysis and firewalls and host security, the SANS GIAC certifications are impressive. Each GIAC holder must study five areas: security administration, forensics, management, auditing, and software security. Most exams are open book and have a time limit of two to five hours, and the candidate must complete the certification within four months of attempting the exams.
The most popular GIAC exams are GIAC Information Security Professional, GIAC Certified Incident Handler, and GIAC Reverse Engineering Malware. All GIAC certification exams must be renewed every four years.
