Additional Security for Dial-Up, Out-of-Band Access to Console Servers

Monday, January 9th, 2012

Although there are plenty of different security and authentication options available for IP communication with a console server, security and authentication options are much more limited for those who need to establish a dial-up out-of-band connection with a console server. Popular authentication protocols such as LDAP, Kerberos and TACACS+ work fine when communicating via IP, but at present, there are few alternatives for authenticating dial-up out-of-band communication.


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.


Effective Security for Dial-Up Out of Band Management Applications

Wednesday, December 21st, 2011

Security and authentication are two vital elements for any out of band management strategy. The reason for this is simple: given the powerful remote access capabilities provided by an out of band management solution, it’s extremely important that access to console port command functions on remote network elements is adequately protected from unauthorized users. While it’s relatively easy to implement effective security and authentication measures when out of band management is accessed via a secondary maintenance network connection, the task of authenticating each user can prove to be much more of a challenge when the out of band management solution is accessed via dial-up connection.


Effective Security for Remote Power Control Applications

Friday, November 25th, 2011

A remote power control solution is a critical element in any network application that involves communication with network elements located at remote equipment sites. The reason for this is fairly simple; without some sort of remote power control solution, the only way to reboot or power On/Off devices at the remote site is an expensive, time consuming trip to the remote site merely to flip a power switch Off and On. But in spite of the obvious value of a remote power control solution, the capabilities provided by a switched PDU can actually do more harm than good if the remote power control solution does not include adequate security and authentication measures.


Out of Band Management via Console Server

Wednesday, November 9th, 2011

Out of band management is a vital capability for any network application that includes communication with remote network equipment, such as is often found at off-site data centers and in distant network equipment racks. When normal network communication with remote network devices is interrupted or not available, an out of band management solution provides an alternative avenue by which network administrators can communicate with remote network equipment in order to restore normal network communication.


Security and Authentication Considerations for Network Power Switch Products

Friday, November 4th, 2011

A network power switch can provide network administrators and tech support personnel with an incredibly convenient tool for controlling power and reboot functions at off-site data centers and remote network equipment cabinets. In many cases, the remote reboot and power control functions provided by a network power switch can allow you to deal with power related problems with remote network elements without the expense and lost time of traveling to the network equipment site in person.


Ensuring Adequate Security for Console Terminal Server Applications

Wednesday, November 2nd, 2011

A console terminal server can provide network administrators with a convenient tool for out-of-band access to console port command functions on vital network elements located at remote network equipment sites. Although this capability can prove to be extremely helpful when dealing with network outages caused by malfunctioning network devices at remote sites, it can also sometimes create a bit of a worry, security-wise, due to the very nature of out-of-band management capabilities.


Remote Power Management Units – Faster and More Economical than a Service Call

Wednesday, August 31st, 2011

When a critical network element at an offsite data center or remote network equipment site suddenly locks up and disrupts communication, the last thing you want to do is send a tech team out to the site to deal with the troublesome device in person. Sure, a service call is often the most obvious solution, but service calls are also time consuming and expensive. A much better solution for dealing with unresponsive devices at distant network equipment sites, is to install a remote power management unit at the site, that allows you to reboot locked up devices without the expense of a service call or the time that is wasted while waiting for the service team to travel to that offsite data center or remote equipment rack.


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.


Callback Security – Effective Authentication for Dial-up Out of Band Communication

Thursday, July 21st, 2011

An out of band management ( solution can provide network administrators with a convenient, reliable means to communicate with remote network devices when communication via network is not available. Although out of band communication is a vital element in many remote network equipment management applications, in most cases, out of band management solutions rely on a dial-up modem connection between the administrator and the out of band management unit.
