When you forget to bring mobile phone, you can’t login the system. But I think such the situation is unusual. It may become mainstream in the future.
I guess that it is difficult to impersonate telephone number. However, one-time password has high security level, but I doubt safety because check code is only 6 numbers.
On the other hand, I guess it isn’t big problem because banks security code is 4 numbers. Also, your account is going to be locked if you misstype several times.
Over 60% Japanese companies which have over 300 employees appointed CISO according to this report. It’s good trend.
Large number of them is given technical work, but the management view or the other departments involvement is still a few. I predict that the people who has high technical skill and low position were appointed CISO. These companies should give CISO more authority.
After you calculated how much does it cost when an security incident occurs, you should think the investment for managing security. In that sense, I think that certainly it’s important that CISO has high technical skills, but the skills which is telling with numbers or adjusting with people including other department is more important.
