By automating scheduled reboots during off-peak hours using remote desktop software, system administrators can avoid interrupting users’ productivity while ensuring that systems benefit from regular restarts to maintain optimal performance.
6. Restarting services
Certain services may encounter issues or become unresponsive over time. To check and restart these services manually can be a tedious task, especially in a distributed system.
Automating the restart of specific services can quickly resolve minor issues without manual intervention. Configuration management tools like Puppet or Ansible can handle service restarts across multiple servers, thereby ensuring continuous service availability and minimizing service disruptions, resulting in an improved system.
7. Remote shutdowns
In cases of emergencies or system failures, remotely shutting down servers or devices can prevent further damage. Automating remote shutdowns using remote management tools like PowerShell’s Invoke-Command or third-party solutions like TeamViewer or GoTo gives administrators a powerful tool to respond swiftly to critical situations.
In the event of a security breach, an automated shutdown of the affected servers can isolate the threat and safeguard other portions of the network from any possible damage.
8. Log rotation
System log files provide valuable insights for troubleshooting and analysis, but they can grow exponentially, consuming disk space and affecting system performance. Automating log rotation using tools like logrotate on Unix/Linux or Windows EventLog Forwarding on Windows ensures that log files are efficiently managed and do not consume excessive disk space.
Regularly archiving and purging logs maintain system performance and make troubleshooting easier by maintaining a manageable set of log files.
9. Malware scans
Security is paramount in system administration, and malware scans are a fundamental aspect of it. Automating regular malware scans enhances system protection and minimizes the risk of security breaches.
To prevent significant damage, system administrators can schedule scans across servers and workstations using antivirus and anti-malware software with automatic scanning features. Cisco Umbrella, Avast Business Hub, and BitDefender GravityZone are good options for this purpose. These programs can detect and mitigate potential threats.
10. User provisioning and deprovisioning
Onboarding and offboarding employees require multiple steps, from creating user accounts to granting access permissions. Automating this process streamlines user management and reduces the risk of errors or security gaps associated with manual procedures. User provisioning automation can include creating user accounts, setting access privileges, and assigning roles based on predefined templates or user attributes.
Tools like Active Directory PowerShell modules or cloud-based identity management solutions like Microsoft Entra simplify user provisioning and deprovisioning tasks.
