Hello Everyone
So I was thinking to apply for one of the leading B schools in my country(Top 30 B school in the world) for its executive MBA program over the weekends. Currently working as IT Security controls testing lead with one of the IT service companies. Now I have 8.5 years of experience excluding a 1 yr break which I took because of personal reasons. By the time I reach 12 years of experience I want to be at Associate Director/Director levels at Pwc, Deloitte ,EY etc... I would like to be involved in Sales/ Account management.
My experience in Info sec is in the Assurance and controls testing arena for the past 3 years. Prior to my current stint in the Controls testing arena I was involved as a VoIP Test engineer for 5 years I have certifications like CCNA, CEH, ISO 27001 LA and ISO 27001 LI. Though I could not clear the CISSP(failed with 66

I got a broad view of IT security and lot of useful knowledge.
My question is would an
Executive MBA help me land such roles as mentioned above or should I study more security certifications like CISSP(reattempt), CISA, OSCP , GPEN, GCIH ? Thing is I am relatively new to infosec, so I was wondering whether I should join exec MBA now or postpone this idea until I have a firm technical base.
Another way to think is that I can do these courses like GPEN and GCIH even after or during the MBA (as its over weekends only).

Any advice would be appreciated.
