One of the main reasons that practitioners use automated scripts is to save time by avoiding manual configurations. Describe additional benefits of using automated scripts for configuring systems in a secure manner for organizations.
Automated scripts offer significant benefits beyond time savings by ensuring consistency, scalability, and enhanced security in system configurations. By automating processes, organizations achieve standardized configurations across all machines, reducing the risk of human error and security vulnerabilities caused by misconfigurations. This consistency is particularly valuable in large-scale environments, allowing systems to be set up identically and securely in a fraction of the time it would take manually (Leiritie, 2023). Additionally, automation supports scalability by enabling the rapid configuration of large numbers of systems, especially in dynamic environments like cloud infrastructures or DevOps pipelines.
From a security perspective, automation helps maintain a strong and proactive security posture. By embedding security policies, encryption standards, and access controls into scripts, organizations can ensure that security configurations are consistently enforced, reducing the likelihood of oversights. Automated scripts also enable rapid response to vulnerabilities, such as applying patches system-wide in response to newly discovered threats (Leiritie, 2023). Moreover, these scripts can be
