Implemented A Secure WLAN Authentication Process For Schools

Implemented a secure WLAN authentication process for schools with

Design and document a secure wireless local area network (WLAN) authentication process.

Assignment Requirements

Other than the Internet, probably no aspect of technology will have more impact on the classroom than the wireless local area network (WLAN), which may soon become as indispensable to the educational mission as chalkboards and textbooks. In the 21st century, technological literacy will be a primary determinant of whether a student succeeds or fails later in life. The ability to access and work with a wide range of information technology (IT) applications will be critical to ensuring this literacy.

The benefits of a pervasive wireless fidelity (Wi-Fi) deployment in primary and secondary education include: Infrastructure Flexibility: School districts’ learning technology needs can be as unpredictable as class sizes. A WLAN can be quickly rolled out virtually anywhere, without the need for extensive retrofitting of existing infrastructure. Speed: Classroom productivity is measured in terms of how much can be taught in a short period. Students can access a WLAN-enabled learning environment in a matter of seconds, without special connections, transmission control protocol/Internet protocol (TCP/IP) changes, or a tangle of cables. Teachers can focus on teaching and students can focus on learning.

Resource Mobility: A WLAN allows technology-learning tools such as laptops to be moved to wherever students are, rather than vice-versa. This makes the concentration of mobile computing resources possible in a single classroom while maximizing hardware utilization and a return on the investment. Deploying WLAN in the classroom can bring enormous benefits, but there are some unique challenges to this environment. For a start, school IT staff is often stretched thin by the support demands of large numbers of users, so the WLAN solution cannot require time-intensive configuration and administration. Schools also pose wireless coverage challenges because of the conflict between their sprawling layouts and the need to provide connectivity to multiple users in the confined area of a classroom.

In addition, given the uncertainties of the school budget process, WLAN deployment costs must be kept low, leveraging existing infrastructure where possible, and offering advantages in terms of scale and price. After reading the given information on the requirements of a school’s WLAN, your task for this assignment is to prepare a professional report. The report should focus on the following: Identify the potential user groups and users of WLAN in a school environment. Assess the WLAN for probable risks in a school environment. Specify security requirements by user class or type.

Mock-up a simplified data classification plan. List and justify particular applications and protocols that should be allowed on the WLAN. Determine whether personal digital assistants (PDAs) should be allowed to access the WLAN.

Introduction

The integration of Wireless Local Area Networks (WLANs) in educational environments has revolutionized access to information, fostering greater flexibility, mobility, and resource sharing among students and staff. A well-designed authentication process is critical to provide secure access while maintaining ease of use, especially given the diverse range of users and devices involved. This paper aims to develop a comprehensive security framework centered on authentication procedures that address the unique needs and constraints of a school setting.

Identification of User Groups

The primary user groups within a school's WLAN environment include students, teachers, administrative staff, IT support personnel, and visitors. Each group has distinct access requirements and security considerations:

  • Students: Require access to educational resources, learning management systems, and communication tools. Their access should be restricted to prevent access to administrative data or unauthorized network areas.
  • Teachers: Need broader access to teaching resources, student data, and administrative platforms. Authentication should verify their identity to distinguish them from other user groups.
  • Administrative Staff: Access to personnel records, financial systems, and other sensitive data necessitates stringent authentication measures.
  • IT Support Staff: Require access to network management tools and configurations, necessitating elevated privileges with secure authentication routines.
  • Visitors: Limited, temporary access to the WLAN should be provisioned, possibly through guest networks with restricted permissions.

Risk Assessment in School WLANs

While WLAN deployment offers significant benefits, it also presents several security risks. These include unauthorized access, data interception, device spoofing, and potential network intrusion by malicious actors. Specific threats relevant to schools encompass:

  • Unsanctioned Device Access: Unauthorized devices connecting to the network can compromise security and interfere with legitimate operations.
  • Data Privacy Breaches: Sensitive student and staff information stored or transmitted over the WLAN is vulnerable to interception or theft.
  • Network Attacks: Denial-of-Service (DoS) attacks, malware, and other cyber threats can disrupt network availability.
  • Physical Security: The expansive nature of school campus LANs necessitates careful physical security to prevent tampering with wireless access points or network equipment.

Security Requirements by User Class

Based on the risk profile and user groups, the following security requirements are recommended:

  • Students: Utilization of WPA3 encryption, device authentication via RADIUS, and application-level security to restrict access to sensitive data.
  • Teachers and Administrative Staff: Strong authentication mechanisms, including multi-factor authentication (MFA), supplemented by role-based access controls (RBAC).
  • IT Support: Elevated privileges secured through MFA, with strict audit logs and access controls.
  • Visitors: Access through a secured guest network with restricted bandwidth and networking privileges, isolated from the internal network.

Data Classification Plan

A simplified data classification plan should categorize all data into levels such as public, internal, confidential, and restricted. For instance:

  • Public Data: School website content, general announcements.
  • Internal Data: Class schedules, curriculum materials.
  • Confidential Data: Student records, staff personal information.
  • Restricted Data: Financial data, health records, administrative reports.

Protocols and Applications Allowed

The WLAN should support only essential protocols to minimize attack surface. Recommended protocols include WPA3 encryption, HTTPS for web applications, and TLS for data in transit. Applications such as email, web browsing, and learning management systems should be permitted, while peer-to-peer file sharing, unsecured protocols, and remote desktop services should be disallowed to maintain security.

Allowing Personal Digital Assistants (PDAs)

Considering the proliferation of mobile devices, allowing PDAs can enhance learning and administrative efficiency. However, their inclusion warrants robust security controls, such as device registration, continuous authentication, and encryption. PDAs with outdated or insecure operating systems should be restricted to prevent vulnerabilities. Ultimately, allowing PDAs can be beneficial if managed appropriately, but strict policies are essential to mitigate risks.

Conclusion

Designing a secure WLAN for schools requires a balanced approach that ensures accessibility, resource mobility, and ease of management while safeguarding sensitive information. Clear identification of user groups, comprehensive risk assessment, role-based security requirements, and rigorous authentication procedures are critical to achieving this balance. Implementing encryption protocols, data classification, and controlled application access are foundational elements of an effective security strategy. Allowing managed access for personal devices like PDAs can further support a dynamic educational environment, provided security measures are enforced actively.
