With the advancement in technology over the past decades, networks have become increasingly large and complex. In the meantime, cyberattacks have become highly sophisticated making them difficult to detect. These changes make securing a network more challenging than ever before. Hence, it is critical to prepare a comprehensive guide of network security management for students assist them in becoming network security professionals. The objective of this paper is to introduce a variety of techniques related to network security management, such as Simple Network Management Protocol (SNMP), event management, security policy management, risk management, access control, and remote monitoring. With the usage of these techniques, malicious activities from outsiders and misuse by insiders can be effectively monitored and managed. A network learning environment is proposed for students to practice network security management experiments. In addition, hands-on lab exercises are suggested. These activities will help students become familiar with the operations of network security management and allow them to further apply practical skills to protect networks.
