Summary What Network and Computer Systems Administrators Do Network and computer systems administrators are responsible for the day-to-day operation of computer networks.

Work Environment Network and computer systems administrators work with the physical computer networks of a variety of organizations and therefore are employed in many industries. Along with most of the other SysAdmin responsibilities, this is to ensure security from external attacks as well as ensuring appropriate, easy access to files for employees. By showing employees how to use systems in a secure, productive way, SysAdmins are able to completely change the way work is conducted within an organization.

If there are any errors with new updates or interdependencies between new versions of systems, the SysAdmin should be able to detect these issues and fix them. SysAdmins should have active, updated plans for redundancies, rollovers and incident recovery. Through effective monitoring, alerting and cross-functional communication , the system administrator should be able to quickly detect any failures and remediate IT incidents.

Security should be top-of-mind across everything a system administrator works on. As they set up networks, policies and servers, the SysAdmin will know how to do it in a technically sound, secure way. SysAdmins are often tasked with maintaining documentation and keeping runbooks up-to-date. System administrators need to know how they can leverage automation to keep runbooks and documentation accurate and updated without slowing the development lifecycle.

They need to build it with visibility and speed in mind. How can you set up a system to allow for rapid incident detection, response and remediation in case an issue does pop up? What kind of monitoring and alerting needs to be in place? SysAdmins should be on top of all of these questions in order to make the most of their incident management practices.

Many times, system administrators will be in charge of conducting post-incident reviews for their affected systems. How long did it take to identify the issue? How long did it take to actually remediate the incident? Keeping up with post-incident reviews, collaborating with other affected teams and taking detailed post-incident notes can help improve IT and software developer relationships — leading to better feedback loops and more reliable deployments.

Use post-incident reviews as a way to learn from your past mistakes and improve people, processes and technology for the future. At the core, a good system administrator will be an excellent problem solver who can find ways to prepare for unknowns. They have the IT know-how to troubleshoot any glitches that interrupt system performance.

Systems administrators handle all of the critical components in business IT infrastructure. They advise senior managers on the best practices to optimize computer networks. Systems administrators suggest new software and upgrades to keep infrastructure current.

They frequently have the purchasing power to buy IT equipment on a set budget. Most play a leadership role in supervising lower-level IT technicians and staff. They oversee the work of computer support specialists and systems analysts.

Systems administrators train other employees on how to access the network and connect devices too. They wear many hats to ensure all computer-related activities run smoothly and efficiently. Succeeding in systems administration requires both hard IT and soft skills. Technical skills are foremost to ensure computer networks are arranged precisely.

Systems administrators are innovative problem-solvers who think outside the box to fix issues creatively. They need critical thinking skills to quickly diagnose IT troubles and develop action plans. Analytical skills help systems administrators run network tests and identify inefficiencies and security vulnerabilities. Leadership skills are needed to communicate policies and enforce protocols for IT department staff.

Speaking skills are critical in order to be able to describe how computer networks work to managers without technical jargon. Systems administrators are savvy with multitasking to make certain all network components work at once.
