Practical Ways to Integrate Linux Security Automation With Ansible

1.Penguin Landscape Esm W350

Linus Torvalds and his colleagues created Linux in 1991 to manage several services in a computer system. This open-source system has proven helpful to cybersecurity professionals for its safety functions and customizability. Ansible, on the other hand, was developed to automate IT processes. We are happy to announce that when Linux’s defensive features combine with Ansible’s automation abilities, the result is a digital stronghold. Thus, we discuss essential methods for integrating Ansible with Linux security administration to address everything from workflow optimization to security improvements.
