There are answers that automate the governance of misconfigurations and people targeted on remediation. Exploring these choices profit your group and must be thought of when designing your cloud technique.

In abstract, cloud adaption doesn’t take away the requirement for a safety chief nor a safety staff. It requires that staff to evolve and adapt if it’s not already an skilled cloud safety supporter.
