What does a Cyber Security System Administrator do?

A Cyber Security System Administrator is responsible for managing, maintaining, and protecting an organization's computer systems and networks. They ensure that security protocols are in place, monitor for threats, respond to security breaches, and regularly update software to safeguard sensitive information. Their role often includes configuring firewalls, managing user permissions, and conducting audits to identify potential vulnerabilities. By implementing best practices and staying updated on emerging threats, they help prevent unauthorized access and data loss.

What are some common challenges faced by Cyber Security System Administrators, and how can they prepare for them?

Cyber Security System Administrators often face challenges such as staying updated with rapidly evolving threats, managing complex security configurations, and responding to potential security incidents. They must balance maintaining robust security protocols while ensuring system usability and minimal downtime. To prepare, administrators should engage in continuous learning, leverage automation tools, and collaborate closely with IT and security teams to implement best practices and coordinate incident response effectively.

  • Perform regular system backups and disaster recovery testing.
  • Perform shift work as required to support N63 operations and exercise and contingency requirements.
  • Proficiency in administering Windows 10 / 11 and Red Hat Linux System operating systems.
  • Understanding of core network protocols (TCP/IP), LANs/WANs, routers, switches, firewalls, and load balancers.
  • Implement and enforce system and security policies based on DoD standards, including STIGS and Risk Management Framework (RMF).

  • Knowledge in MOC, DFC Ops, Joint Range Application C/Link 16 Protocols.
  • Administer and maintain VMware virtual environments, including vCenter Server Appliances and ESXi hosts, to ensure stable operations.
  • Manage NetApp storage arrays, providing high-performance NFS services and efficient volume management to meet data-intensive needs.
  • Deploy and maintain Gigamon V-Series virtual taps to support comprehensive traffic monitoring and visibility within the virtual environment.
  • Maintain high availability through strategic VM migrations to mitigate maintenance impacts and ensure maximum system uptime.
  • Execute software life-cycle management by staying current with the latest versions of ONTAP, ESXi, Center, and VMware Tools.
  • Enforce cybersecurity compliance by applying DoD STIGs and ensuring successful weekly vulnerability scans across all managed systems.
