Identity and access issues rarely begin as security failures. They usually begin as
convenience decisions that were never revisited.
Temporary access becomes permanent. Service accounts outlive the services they were
created for. Users change roles, but their permissions follow them indefinitely.
Over time, access models reflect historical accidents rather than current needs. This
is especially visible in Linux environments that have grown organically, where local
accounts coexist with directory-backed identities and SSH keys are copied forward
without clear ownership.
The result is not usually a dramatic breach, but a persistent lack of confidence. Teams
cannot say with certainty who has access, from where, or for what purpose. That
uncertainty is itself a security risk.
Improving access control often means revisiting old assumptions and being willing to
remove privileges that once made sense. Identity work is less about introducing new
tools and more about untangling the past.
