Microsoft Releases Out-of-Band Critical Security Patch MS14-068 Today

Tuesday, November 18th, 2014

It sounds like this is more of a problem on the server side than it is on the client side, but either way, it’s a good argument for keeping one’s PC up-to-date, patch-wise.

Microsoft released fourteen security bulletins last week on this month’s patch day. If you read the patch notes or our summary, you may have noticed that two bulletins were mentioned but not released on that day. It is unclear why the two bulletins were listed by Microsoft but not released on the day. One explanation for this is that the company needed more time to create patches for affected systems.


Why Should a Console Manager Support More than One Authentication Protocol?

Wednesday, January 4th, 2012

When you consider the powerful network management capabilities provided by a console manager, it quickly becomes clear that security and authentication are both vital elements for any truly effective console manager application. In order to protect remote access to console port command functions, an effective console manager must provide adequate security and authentication measures to ensure that only valid users are able to access the console manager, and also support a variety of different remote authentication protocols in order to ensure compatibility with the needs of different types of authorized users.


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 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.


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.


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.


Authentication Protocols Provide Additional Security for Console Server Management Applications

Wednesday, May 11th, 2011

When implementing an out of band management solution, it’s important to make certain that remote access to console port command functions is adequately protected. Obviously, this means that your console server management ( unit should include basic security features such as password protection. But in order to properly ensure that sensitive command functions are protected from unauthorized access, your console server management device should also support one or more of the popular remote authentication protocols.


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.
