1. I was told a certified ISO 27001 LA can train and certify other people?
For ISO 27001 compliance purposes, a certified ISO 27001 Lead Auditor has recognized knowledge and skills that allow him to train other people.
Regarding certification, in theory, everyone can issue a certificate, but for the certificate to be recognized it should be issued by a trustworthy organization.
A certification issued by a certified ISO 27001 Lead Auditor has limited recognition (normally it is recognized only by the organization he works for).
On the other hand, a certificate issued by an accredited training provider is often worldwide recognized.
In short, if your need for certification is only for internal purposes, a certified ISO 27001 Lead Auditor can issue that for you. In case you need a certification wildly recognized, you should look for an accredited training provider.
2. If true? is there a special certificate/training to be able to do this?
To become a certified ISO 27001 Lead Auditor you need to attend an ISO 27001 Lead Auditor course from an accredited training provider and be approved in its final exam.
