Protecting Credentials and Privileged Accounts in the Cloud

Privileged accounts, such as the root administrator of a cloud account, concentrate a disproportionate capacity for damage compared with any other identity, because compromising them can mean full control of the entire infrastructure, including backups and audit logs. Protecting them requires stricter measures than other accounts: multi-factor authentication with physical hardware, restricted use only for tasks that really require it, special monitoring of every action they perform, and storing credentials in dedicated vaults instead of configuration files or accessible environment variables. This matters because attackers with limited initial access invest much of their effort in escalating privileges precisely toward this type of account. A frequent and avoidable example is finding an administrative account's access keys written directly into an application's source code, visible to anyone with access to the repository.
