Placing Lindy Kvm Ip Alongside The Firewall - Lindy Switch User Manual

Placing LINDY KVM IP alongside the firewall

LINDY KVM IP is built from the ground-up to be secure. It employs a
sophisticated 128bit public/private key system that has been rigorously analysed
and found to be highly secure (a security white paper is available upon request).
Therefore, you can position the LINDY KVM IP alongside the firewall and control
hosts that are also IP connected within the local network.
IMPORTANT: If you make the LINDY KVM IP accessible from the public Internet
or from a modem, care should be taken to ensure that the maximum security
available is activated. You are strongly advised to enable encryption and use
a strong password. Security may be further improved by restricting client IP
addresses, using a non-standard port number for access or limiting remote
access to dial up connections only.
Ensuring sufficient security
The security capabilities offered by the LINDY KVM IP are only truly effective
when they are correctly used. An open or weak password or unencrypted link
can cause security loopholes and opportunities for potential intruders. For
network links in general and direct Internet connections in particular, you should
carefully consider and implement the following:
• Ensure that encryption is enabled.
By local configuration or by remote
• Ensure that you have selected secure passwords with at least 8 characters
and a mixture of upper and lower case and numeric characters.
By remote configuration.
• Reserve the admin password for administration use only and use a non-
admin user profile for day-to-day access.

• Add a further level of inherent security by restricting access only via modem

Security can be further improved by using the following suggestions:
• Use a KVM switch with On-Screen-Display driven security access and an auto-
logout (after inactivity) feature to provide a second level of security.
• Place the LINDY KVM IP behind a firewall and use port the numbers to route
the VNC network traffic to an internal IP address.
• Review the activity log from time to time to check for unauthorized use.
• Lock your server consoles after they have been used.
A security white paper that gives further details is available upon request.
Ports
In this configuration there should be no constraints on the port numbers
because the LINDY KVM IP will probably be the only device at that IP address.
Therefore, maintain the HTTP port as 80 and the VNC port as 5900.
Addressing
When the LINDY KVM IP is situated alongside the firewall, it will require a public
static IP address (i.e. one provided by your Internet service provider).
