Threat Monitoring and Mitigation

Use: Malware, spam and attack prevention
Eligibility: Requires an Internet connection from MOREnet. This service is free and applied to all connections by default.

MOREnet blocks millions of malicious IP addresses on our backbone in order to protect your network from malware, phishing, spam and other threats. New threats are blocked on a regular basis. If you are connected to the MOREnet network, you can count on us as your first layer of protection.

Good Network Neighbor Service – Microsoft Ports (GNN 1)

Use: Malware/attack prevention
Eligibility: Requires an Internet connection from MOREnet. This service is free, but you must sign up.

Our GNN 1 service blocks the Windows Networking ports known to be prone to exploitation by viruses and other malware. This service also eases the load on your firewall by blocking the nuisance scanning of these ports and reducing the amount of traffic it needs to process.

Good Network Neighbor Service – SMTP (GNN 2)

Use: Prevents unauthorized e-mail from leaving your network.
Eligibility: Requires an Internet connection from MOREnet. This service is free, but you must sign up.

Malware will often install an SMTP server on infected systems in order to send spam. GNN 2 will prevent these infected systems from sending e-mail outside of your network. This could prevent blacklisting of your network, keep systems from sending out infected attachments, and stop inappropriate messages that could tarnish your reputation. This service will not prevent infected systems from sending messages through your authorized e-mail server.

Blackhole DNS (BHDNS)

Use: Malware prevention
Eligibility: Requires MOREnet membership. This service is free, but you must make a configuration change on your network.

Using our Blackhole DNS service is an important layer in preventing malware infections. We blacklist thousands of malicious domains every week and often block newly registered domains before they are used for malicious activity! This free service will help you recover staff time that is being used to clean infected systems.

E-mail Virus and Spam Filtering (EVSF)

Use: Spam and malware prevention
Eligibility: Requires MOREnet membership or a MOREnet connection. Fee-based service for those who manage their own e-mail servers.

E-mail viruses and spam are two of the biggest hassles system administrators have to deal with on today's Internet. This low-cost MOREnet service provides e-mail system protection on the MOREnet backbone, saving local administrators time and money. Because MOREnet removes the large majority of spam before it gets delivered to your local systems, this will reduce processor load and may increase the longevity of the mail server or local spam filtering device.

Internet Content Filtering (ICF)

Use: CIPA compliance, local policy enforcement, and malware prevention.
Eligibility: Requires MOREnet membership.  Fee-based service.

MOREnet offers an Internet filtering solution that can be managed locally or by MOREnet support staff.

Incident Response and Technical Support

Use: Incident management and mitigation, bandwidth analysis, general security questions, and security notifications.
Eligibility: Requires MOREnet membership or a MOREnet connection.  This service is free and applied to all connections by default.

MOREnet’s security team includes trained and experienced personnel. We won’t just tell you that you have a problem; we will assist you with trying to fix it! The security team belongs to several national groups that allow us to be on the cutting edge of threat discovery, mitigation and notification.  We proactively look for malware infections, before the problem becomes much worse for our customers. Contact us as your resource for security research and guidance.
