Infosecurity 2013 saw a panel of respected CISOs reveal the skills they've needed to be successful in their roles, together with advice on what was needed to take on such a role for an organisation.
"We deal in what is a very technical discipline in information security," said John Meakin, head of security and technology risk, markets and international banking at RBS. "And yet we're liaising with people, 99.9 per cent who don't speak the same language."
"The key challenge for a CISO, not just for himself but also for the team, is to speak convincingly in a language that mere mortals can understand."
Avtar Sehmbi, head of information security at Centrica, added that a business was there to make money foremost, so any discussions around security risk always needed to have that in mind.
He said, "It's taken me years and years to work out the business perspective first and then look at the risk perspective, although they intertwine."
"You do need some kind of engagement strategy. You're selling what you're doing, your initiatives and your views on risk. It's really crucial."
Sehmbi believed that anybody could become a CISO, but many years grounding in different information security disciplines really helped, and that having a good team and hiring the right people was vital.
He said, "You're expected to know all the intricate details, as well a holistic picture. Having that 10, 15, 20 years of grounding is really quite useful."
On the other hand, Simon Riggs, SVP, regional ISO EMEA at Bank of America Merrill Lynch, did not think you necessarily needed to have lots of experience in the security industry for a CISO role.
"You can take transferable skills from any discipline and bring them to the role. That general managing perspective, marshalling the right people and focusing on the right things, doesn't require 25 years in the industry."
