Some sites track the appearance of certain criteria in job advertisements, and this can be a good guide as to what employers are looking for in terms of qualifications.
 So which are the most popular certifications for IT Security?

Let's look at some data from www.itjobswatch.co.uk and compare 7 IT Security qualifications, and 7 generic IT qualifications:
