Are you known for your meticulous attention to detail and knack for navigating complex network infrastructure and computer security tasks? If so, then the role of a network systems administrator might be the ideal career path for you. But what exactly does a network systems administrator do?
What Does a Network Systems Administrator Do?
A network systems administrator (NSA) is responsible for installing, configuring, and maintaining a company’s network infrastructure. The myriad of tasks they focus on includes:
Identifying Network Needs
NSAs determine and implement the appropriate network configuration by installing the necessary hardware and software.
- LAN (Local Area Networks): Connects groups of computers over short distances to facilitate resource sharing.
- WAN (Wide Area Networks): Connects computers over longer physical distances than a LAN.
- WLAN (Wireless Network): Utilizes Wi-Fi, eliminating the need for physical cables.
Upgrading and Repairing
They identify opportunities to upgrade and repair the network to maximize uptime, as lost network uptime results in lost employee productivity.
Maintaining Security
NSAs implement robust security protocols, including:
- Firewalls: Monitors network traffic and decides whether to allow or block based on security rules.
- Gateway: Hardware separating two networks, often equipped with a firewall to manage traffic.
- Zero Trust Network Access: Ensuring users have only the necessary access and permissions for their role.
- Intrusion Detection Systems: Watches for suspicious network traffic and reports it.
- VPN (Virtual Private Network): Protects data transmitted over the Internet.
- SSL (Secure Sockets Layer): Secures internet connections through encryption.
Email Security
They protect email accounts and content from outside threats, including attachment opening protocols to prevent virus infections.
Intrusion Prevention System
They prevent network attacks such as brute force attacks, Denial of Service (DoS), and known exploits.
Sandboxing
NSAs run code or files in a safe, isolated environment to identify potential threats to the network.
Anti-Virus Software
They identify and block viruses before they infect the computer or network.
Improve System Performance
They evaluate and optimize the network to ensure peak performance.
Give User Security Permissions
NSAs act as a liaison between the network and users by assigning security permissions to network functionality and software suites.
Train Users on Proper Protocols
They train users on essential protocols for password protection, attachment issues, software upgrades, and other critical information to maintain network safety and security.
