Do you feel that computer science and information systems programs should also require professors to have professional certifications in addition to the normal publishing requirements for tenure or job acceptance?
I have the CISSP, CSSLP and the CFE currently active. From my perspective they measure how much one knows of the theory. These would be good as part of continuing education for professors. However I would suggest other certifications such as SANS, CCE or other hands-on type certifications which prove that professors know how to apply the knowledge as opposed to just the theory.
Certifications are just a measure of some knowledge according to some standard. In the same way a PhD, MSc or a BSc provide a measure of capability and in what field. All merits are always good to have. Further in order to teach students a knowledge about the required standard knowledge necessary is indeed good to have.
I find those professional certifications e.g. CISSP, CCSK, PMP, ITIL Mgr / Expert etc. demonstrate a person have minimum knowledge on some domain knowledge related to industrial work environment. If you are working in industrial / professional environment like commercial & consulting, then those certification might carry weight (or serve as "passport" to get a job). However, I also came across some people without those certifications but know more than those certified as they had learned the hard ways from the work environment for many years & without ceasing to learn from Internet & YouTube - but some of them might not get the job or same pay because they lack the "passport" (professional certification).
I think holding some industrial / professional certifications are also beneficial to those academicians in universities / research institutes as they can broaden their horizon of knowledge from industrial work environment. This can bridge the gaps / eliminate some disconnects between the academicians and industrial subject mater experts during their interaction / interlock.
