Study Notes

SecureBank's Network Access Control Implementation

SecureBank faced challenges managing its network access with a diverse mix of employees, vendors, and devices.
Key issues included lack of visibility and control over device connections, unauthorized access, and no enforcement of security policies.
SecureBank chose Cisco Identity Services Engine (ISE) as their NAC solution due to its compatibility with their existing Cisco infrastructure and comprehensive features.
The implementation involved defining access policies for employees, personal devices (BYOD), third-party vendors, and guest users, with varying levels of access and security requirements.
Authentication methods including 802.1X, MAC Authentication Bypass (MAB), and a web-based guest portal were implemented to secure network access.
Device posture assessment ensured device compliance by checking for antivirus status, operating system patches, and firewall status.
Non-compliant devices were quarantined or denied access, with users directed to instructions for regaining access.
The network was segmented into VLANs for employees, vendors, guests, and quarantined devices.
A pilot test was conducted before full deployment, identifying and resolving issues.
The successful implementation of NAC resulted in enhanced security, improved visibility, seamless user experience, automated compliance enforcement, and role-based access control.
SecureBank's case study highlights the benefits of NAC in securing a network by controlling access, enforcing compliance, and improving overall security posture.
