Most large organizations and enterprises at least try to take security pretty seriously. This means that the front door is not only usually locked, it is fortified and reinforced. This makes it hard for the bad guys to get in. So, do they give up? Of course not! What they do instead is look around back and start rattling the door knobs on the shed and cellar and the servants entrance and try to work their way in that way.
High value targets are usually locked down and secured pretty well, but this is not always the case for lower value targets. Once compromised, these lower value targets can provide a useful platform from which to attack other systems. For example, while traffic from the internet to internal hosts may be tightly limited, in many cases traffic between machines in the DMZ may not be as well regulated. Thus if you can own one machine in the DMZ, it can be easier to compromise other systems.
A collaboration of four senior members of the Cisco IPS signature team recently culminated in the public release of a guide on writing custom signatures for Cisco IPS, the #1 IPS platform of the Internet. The idea behind this move is to give our customers an easier way to develop their own signatures, allowing them to more easily discover and block unwanted traffic in their networks. At the same time it helps in understanding existing signatures written by members of the IPS signature team.
You can protect your small business wireless network from intruders with a few simple tweaks
A wireless network makes sense for small businesses. It enables you to connect wired and wireless devices, allowing you to expand your network operations and keep employees productive. Also, a wireless LAN (WLAN) is easier and less expensive to set up than a wired network, and gives employees and guest users quick, convenient access to the Internet from anywhere in your office.
Deploying a wireless network is easy in part because the networking equipment, including wireless routers and wireless access points, ships with important configuration settings preconfigured. However, these preset passwords, along with other improperly set configurations, can lead to catastrophic breaches in network security. To ensure your wireless network is secure, the devices must be configured to block intruders and protect users.
Here are five changes you can make to your WLAN configuration settings to lock down your wireless network and provide business-class security:
I read an article recently discussing the advantages and disadvantages of smartcards. I know that there have been quite a few distributed, but it seems to me that the adoption rate and the length of time they have been available are a bit out of sync. I would have thought that we would have many more smartcards, used in more places, being as they werer actually invented in 1968, and were widely used in French pay phones starting in 1983.
Stealing a quote from Arthur C. Clarke: “Any technology, sufficiently developed, is indistinguishable from magic”. Some people would certainly consider security these days as magic. Okay, so much for that reference, but what does Star Trek have to do with government and security, my typical topics. Star Trek, although mostly about exploration sure seemed to have a bit of a “Space Military” characteristic to it. Isn’t that what the Star Fleet was all about? (no offense intended, Capt. Kirk.)
Lately, I’ve been doing some research for a paper on the integration of physical and logical security (I did an initial paper that you can see here: Click on “The Necessity of Security”) and it dawned on me how very similar the technology of today is to the science fiction of the 1960’s, or in Mr. Clarke’s case, magic. So here is a synopsis of some of my observations. I’m sure there are more; please feel free to reply with what I’ve missed or your own favorites.
