LAN Security

	The Challenge: Keeping Dangerous Systems Out

Corporate firewalls and remote authentication were once enough to secure a network, but mobile systems connecting to the core network have made this model vulnerable to attack. As a growing number of systems cross between trusted and untrusted networks each day, network security on the LAN lags behind perimeter defenses.

A system on an untrusted network can become infected with a Trojan or virus. When the system attaches to a trusted network, the malware spreads to other systems. Even if operating systems, antivirus and security software are updated, the constant changes to desktop configurations makes this process prone to failure when scaled to hundreds or thousands of systems.

	Solutions

Dynamic NAC for Windows is a software version of network access control that supports Dynamic NAC. Dynamic NAC is easy to install and maintain, requiring no network reconfiguration or equipment upgrades.

CyberGatekeeper Server keeps unhealthy PCs and rogue devices off the network. Unhealthy PCs are remediated before granted access to the network. CyberGatekeeper monitors and controls access to the network regardless of its configuration, quarantining unauthorized endpoints on the network, even when they are not running DNAC software.

• CyberGatekeeper Server audits all local systems and only grants access to those in compliance. This ensures a secure network regardless of user type and system configuration.
  
  
• If no audit is performed on the system, the system remains quarantined, unlike other systems, which permit access when no software is installed.

• The Desktop Agent can participate in an audit session with the CyberGatekeeper server. Systems without a desktop agent, such as those owned by business partners and consultants, can use the Web Agent to establish an audit session.
