Security and Authentication for Remote Power Switch Applications

Monday, January 2nd, 2012

A remote power switch can provide a network administrators with a valuable tool for switching, metering and rebooting power to remote network equipment; often allowing administrators to deal with problems at remote equipment sites without the need to travel to the site in person. But in order for a remote power switch to be truly useful, it must also support adequate security and authentication measures in order to protect power control and reboot functions from unauthorized use.


IP Address Filtering – A Versatile Security Feature for Console Servers

Thursday, September 1st, 2011

When used properly, a console server can provide network administrators with a broad array of powerful tools that can be used to manage remote network elements, monitor conditions and events at remote network equipment sites and access console port command functions on remote network equipment. As is often the case though, these powerful tools also have a harmful potential if they are available for access by the wrong people. With this in mind, it’s easy to see how important security and authentication measures are to any console server product, and that in many cases, the more layers of security that are available to protect the console server, the better.


Why Are Security and Authentication So Important for Console Access Servers?

Wednesday, August 17th, 2011

A console access server provides network administrators with a convenient “back door” for out-of-band access to console port command functions on remote network elements. Although this function can prove extremely valuable when troubleshooting communication problems at remote sites, it’s also a good idea to keep in mind that without proper security and authentication features, a console access server can also present a potential weak spot in your network security.


Secure Out of Band Access to Console Port Command Functions on Remote Network Elements

Monday, June 13th, 2011

It’s pretty hard to imagine how difficult it must have been to maintain and service remote network devices before the advent of out of band management. Not too long ago, before the concept of out of band management was widely embraced, the only way to deal with a troublesome network element at a remote equipment site was to travel to the equipment site in person and initiate a power reboot or invoke a few quick console port commands in order to get a troublesome network element up and running again. For a large part, out of band management has almost completely eliminated the need for IT support personnel to be constantly on the road traveling from remote site to remote site, just to reboot misbehaving devices or change a few configuration parameters.


A Multi-Layered Approach to Console Terminal Server Security

When deploying a console terminal server ( in an out of band management application, one of the most important considerations is adequate security. Ideally, console terminal servers should be protected by multiple layers of security and authentication features, and generally speaking, the more layers the better. In addition to more common security features such as password protection and authentication protocols such as LDAP or RADIUS, some console terminal servers include an IP address filter, which enables the console terminal server to accept or reject potential users based on their IP address.


Direct Connect – A Useful Feature for Out of Band Management Applications

In addition to providing out of band access to console port command functions on remote network elements, a full-featured out of band management ( unit should also include functions that allow the unit to easily adapt to the requirements of a wide range of different network based applications. For example, if the out of band management unit will be deployed in a remote network management application that requires automated access to console ports on various network elements, then direct connect capability can often prove to be very useful.


Out of Band Management – A Secure, Reliable Way to Deal with Problems at Remote Network Equipment Sites

Monday, May 2nd, 2011

When a network element at a remote installations site malfunctions, the last thing you want to do is send your IT support team off on an expensive, time consuming trip to visit the site in person. Not only are truck rolls and service calls often a waste of time and money, but if your remote network equipment site includes an out of band management solution with adequate security and authentication measures, then a service call is often completely unnecessary.


An IP Address Filter Provides an Additional Layer of Security for Console Server Applications

Friday, April 15th, 2011

When deploying a console server ( as a part of an out of band management solution, it’s always best to take a multi-layered approach to system security. In addition to basic password protection, a console server should also support authentication protocols such as LDAP, Kerberos and TACACS+, as well as other secondary measures such as call-back security for modem based applications and alarm features to let administrators know when security might potentially be threatened. If the IP addresses of all potential console server users is known, then an IP Address Filter can also help to improve security and prevent unauthorized access.


IP Address Filtering – A Very Useful Feature for Console Terminal Server Applications

Thursday, March 17th, 2011

When network administrators need to establish an out of band connection to a console port on a remote network device, they often rely on a console terminal server ( When normal network communication is down or unavailable, a console terminal server provides a reliable, secure means to communicate with remote network elements without relying on normal network communication. Given this powerful ability to communicate with vital network elements, it’s extremely important that console terminal server units include a multi-layered approach to system security. An IP address filter provides yet another layer of security to protect console terminal server functions from access by unauthorized users.


The IP Address Filter – An Important Element in Console Terminal Server Security

Thursday, February 17th, 2011

A console terminal server is a vital part of any out of band management application. In addition to environmental and event monitoring and alarm functions, a console terminal server can also provide out of band access to command functions on remote network equipment, even when your main network is down. Obviously though, it’s also very important that a console terminal server includes adequate security measures in order to prevent unauthorized access to the same command functions that make it so useful.
