The campus network is an important channel for students to access information and learn, but also faces security risks: account misappropriation, identity fraud, breaking speech, cyberattacks, etc. As a university, it not only provides easy access to the Internet for students, but also assumes responsibility for managing the network by implementing requirements for real name management, log retention, content auditing, etc. The campus network Authentication & Billing has a central role in safeguarding physical names and security compliance.
The mandatory certification is the first line of security.
The first line of defense for network security is access control. For campus networks, the Authentication & Billing system ensures that all users must have access to the Internet before they can be certified, and non-certified users only have access to certified Portal pages and limited resources within the school, without direct access to the extranet. The mandatory certification has blocked unauthorized access from the mechanism and ensured that every user on the Internet has a clear identity record. For campus networks, compulsory authentication is not an option but rather a basic requirement for safety compliance: both educational authorities and public security departments require that campus web sites implement a real name system, and all users on the Internet must register their names. The strictness of mandatory certification directly determines the effectiveness of all subsequent security measures——If the portal is not controlled, there can be no subsequent logs, audits, and retrospectives. The campus network NATSHEL_AUTH_BILLING system needs to support multiple forms of authentication, but either way it must ensure that certification is mandatory and non-extractable.
Authentication and security of identity
After the entrance is under control, the next step is confirmation."Who's the guy on the Internet?"The campus network NATHELL_AUTH_BILLING ensures that every Internet account corresponds to the true student identity through its interface with the system of study workers: school numbers, names, professional and grade information is consistent with the system of study workers; students are automatically open accounts when they enter school, and their graduations are automatically closed, avoiding anonymous or ghost accounts. For visitors and temporary users, the system supports real name authentication for mobile phones, ensuring that each temporary user also has a true identity record. It is important to note that the real name certification involves the privacy of students, and that systems should follow compliance requirements in collecting and using student information, protect data, and do not ignore students’ privacy because of authenticated names. Schools should develop clear systems for managing student network information and regulate the process of gathering, using, storing and destroying information.
Retention of logs and audit of online practices
The campus network Authentication & Billing records the authentication time, down-to-line time, access location (AP/exchange/port), IP address, MAC address, online duration and traffic usage information for a complete web log. Whether the logs are able to be personal, account number, terminal, time-by-time, location-by-place, and location-by-location is an important criterion for measuring system security management capacity. The campus network Authentication & Billing requires support for long-term storage and quick search of logs, which can be quickly located to specific users, times and behaviours when cybersecurity incidents occur or public security requests collaboration. For scenarios requiring in-depth content audits, the system can also interface with third-party online behaviour management devices or audit platforms to achieve audit and record content on the Internet.
Account security and anti-piracy
The campus network accounts are important assets for students, and their misappropriation may result in leaking information from students, loss of Internet fees or even legal liability. The campus network NATSHEL_AUTH_BILLING requires a well-developed account security protection capability: one is a password strategy that forces students to set up passwords with sufficient complexity to regularly remind them to change the code to prevent weak passwords; two is access protection, which supports unusual login detection (e.g. very frequent place login, very expensive equipment login, multiple login failure at short notice), prompt warning or request secondary validation; three is simultaneous control, limiting the number of items that are online on the same account and preventing multiple users from sharing the account numbers; The system should also support students in their self-help functions such as password recovery, password modification, and access login to enable them to manage their own account security proactively. Account security is an important component of the safety of the campus network, and the system needs to balance safety with ease, neither by too complex a security measure to affect students’ experiences nor by ignoring safety because it seeks to be easy.
NATHHEL_ANTI_SHARING Anti-agent and network resource protection
The common problem in the operation of campus networks is private sharing: a student account that allows multiple devices to be shared online through routers or software, amounts to a disguised bypassing of certification and billing, which not only harms school operating income but also poses security risks. The campus network Authentication & Billing system supports part of Anti-Sharing, anti-agent functions, through deep detection by DPI, identifying shared behaviour with end characteristics and user identification, and implementing disruption or speed containment strategies. Such functions effectively protect school operating revenues and network resources, which are commonly used as controls for fee-for-school campus networks. Besides NATSHEL_ANTI_SHARING, the system can support pro-advisor functions, VPNs, and flip walls, which are selected for use in accordance with school management requirements. It should be noted that these functions are used in conformity with relevant laws and regulations and school administration systems, and cannot over-monitoring students’ Internet behaviour and infringe on their privacy.
Security compliance management and system-building
Technical means are only part of security compliance, and systems development is equally important. Schools should establish a well-developed system for cybersecurity management, including user real-name registration systems, account management systems, log management systems, emergency response systems, information security training systems, etc., with clear responsibilities for the safety of departments and personnel. The campus network NATSHEL_AUTH_BILLING should be able to provide technical tools and managerial functions that fit into school security management systems. For example, the system can support electronic signing of user access protocols, and students must read and agree on the School Network Use Management System when accessing the Internet for the first time; The system supports the flexible configuration of security strategies, adapting certification methods, access control and log retention strategies to school management requirements; it can support the generation of safety audit reports, providing data support for security checks and compliance assessments in schools.
The campus network Authentication & Billing system builds a full line of physical name and security compliance with the campus network through technical means such as mandatory certification, real name authentication, log retention, account security, Anti-Sharing proxies. It protects both online resources against misuse and student accounts from being used, and also meets the requirements for educational authorities and public security. For schools, the security capabilities of the campus network Authentication & Billing system are truly operational and are coupled with a well-developed security management system to ensure that the real name and safety compliance requirements of the campus network are implemented, creating a safe, credible and controlled online environment for students and also protecting the school ' s informationization infrastructure.
