This includes tasks such as setting up and configuring network hardware and software, monitoring network performance, maintaining network infrastructure, troubleshooting issues, and implementing security measures to protect the network from threats. Network administrators are responsible for ensuring that the network remains reliable and available to users, and they often work to optimize network performance and plan for future network growth. Network Administration Goals Goals Maintaining Resiliency: Ensuring network resilience and consistent functionality and availability. Capacity Planning: Planning and enhancing capacity to ensure smooth access and operations. Automated Management: Utilizing networking tools for automated management and improved control. Change Tracking: Monitoring and recording essential changes. Risk Management: Assessing potential risks and implementing effective mitigation strategies. Security Prevention: Preventing actions that could compromise the network or turn it into an attack vector. Intrusion Detection: Detecting and addressing intrusions to prevent security breaches that could jeopardize data. Key Areas Key Areas Fault Management This area is dedicated to overseeing the entire infrastructure, aiming to detect and resolve issues that might impact it. Fault management employs standard network protocols like Simple Network Management Protocol (SNMP) to monitor the infrastructure. Configuration management Configuration management involves tracking and managing changes to network components, such as switches, firewalls, hubs, and routers. Unexpected changes can significantly impact the network, potentially causing downtime. Therefore, it is crucial to efficiently streamline, monitor, and control configuration changes. Key Areas Account management Network usage can greatly impact various components. Account management helps track this usage, allowing organizations to estimate, plan for, and possibly bill different departments accordingly. While smaller organizations might not prioritize account management and billing, monitoring network utilization is crucial for all networks, as it can reveal trends and inefficiencies. Performance management To ensure efficient operations, administrators must prioritize maintaining service levels, which is where performance management becomes essential. Performance management involves gathering metrics and analytical data to continuously evaluate network performance, such as response times and packet loss. Key Areas Security management Security management, a critical aspect of network administration, focuses on ensuring that only authorized activities, devices, and users have access to the network. This involves employing various strategies, such as threat management, intrusion detection, and firewall management, to keep the network secure. Security management includes gathering and analyzing network data to identify and prevent malicious or suspicious activities. What is a Network Administrator? Network Administrator A network administrator is an IT professional responsible for overseeing an organization's network. This role requires extensive technical expertise, and the network administrator is typically the top technical authority within the organization. Their duties include ensuring the network remains operational, monitoring its functions, and managing its operations. Additionally, network administrators are responsible for installing, maintaining, and upgrading the software and hardware necessary for the efficient operation of the network, which may include local area networks (LANs), wide area networks (WANs), the Internet, and intranets. Roles and Responsibilities of a Network Administrator Roles and Responsibilities Assess the organization’s network and system needs. Research and evaluate network devices, protocols, services, and standards to support network functions. Install and maintain network servers and operating systems, ensuring that backup copies of all files are securely stored in a designated location. Troubleshoot issues with network devices and perform updates as needed. Install, configure, and manage multi-user software on servers. Oversee and maintain end-user accounts, authentication processes, and permission settings. Install, configure, and manage network communication devices, such as hubs, switches, and UPS systems. Roles and Responsibilities Ensure the proper functioning and maintenance of all network-connected devices. Manage security measures, including antivirus software, firewalls, and intrusion detection systems. Install and configure software, hardware, and other devices to meet the organization’s network requirements. Network Documentation Network Documentation Network documentation is the process of recording detailed information about a computer network's configuration, components, and operations. This includes documenting network diagrams, hardware and software inventories, IP addresses, network configurations, and procedures for setup and maintenance. Network documentation helps ensure that network administrators and IT staff have a clear understanding of the network’s structure and can efficiently manage, troubleshoot, and upgrade the network. It also aids in compliance, security, and disaster recovery planning. Benefits and Importance Benefits and Importance Visualization Creating a diagram that includes all hardware, cables, servers, and cloud connections provides a visual representation of your network. This layout helps you identify potential weaknesses and understand how traffic congestion might be impacting the flow of information. Troubleshooting Troubleshooting becomes much simpler when you can pinpoint the exact location of a problem. Consider the time saved during a system failure or unexpected issue with crucial devices. Having a virtual infrastructure map can enable you to restore your company’s operations in a fraction of the time. Benefits and Importance Standard Operating Procedures Relying on only one or two people to understand how your network operates can be problematic if they're unavailable when needed. A network documentation tool allows any IT-savvy individual to step in and continue where the previous person left off. Budgeting and Forecasting Documenting your network assists with capacity planning as your organization grows, helps identify and update non-functional devices, and allows you to transition to network documentation software for improved efficiency. Benefits and Importance Saving Money The more familiar you are with your computer network devices, the better you can manage them. This increased efficiency can lead to cost savings, ultimately benefiting your bottom line. QUESTIONS? Network Simulation Continuation of MOOC  Asian SEED Academy of Technology Network Administration Week 2 09309786098 [email protected]
