With more than a billion monthly active users, it's easy to imagine that most of the data travelling over Facebook's networks is delivering photos, status updates and "likes" to its end users, but that's far from the case.

The social network moves about 1,000 times as much data between the servers inside its data centers as it does from its servers out to end users, company executives said Wednesday. They talked about the challenges that this creates for Facebook and the network technologies it's developing to overcome them.

NirSoft has announced the public availability of DNSQuerySniffer, a tiny (130KB, including a Help file) network sniffer which detects and displays your DNS traffic.

If you think this sounds just a little technical, then you’re right, but the program does have some interesting applications. Malware will often use DNS traffic to communicate with its operators, for instance, and so taking a closer look at your own system may reveal the signs of an infection (a large number of failed lookups to domains you don’t recognize, say).

We've all heard of a distributed denial of service (DDoS) attack and know what it is: when a person or people attempt to take down a Web site by flooding it with connection requests. These max out the site's bandwidth, making it unable to accept new requests. The attacks are usually automated and can be accomplished in a variety of ways. The loss of traffic during the attack itself, and the recovery afterward, can end up costing Web sites quite a lot.

While digging through the data unearthed in an unprecedented census of nearly the entire Internet, Researchers at Rapid7 Labs have discovered a lot of things they didn't expect to find openly responding to port scans. One of the biggest surprises they discovered was the availability of data that allowed them to track the movements of more than 34,000 ships at sea. The data can pinpoint ships down to their precise geographic location through Automated Identification System receivers connected to the Internet.

Like bring your own device (BYOD) before it, the march of bring your own network (BYON) is happening silently, stealthily and almost completely outside of management control.

Nearly all modern smartphones and 3/4G tablets can be instantly turned into wireless hot spots allowing them and any other wireless-enabled systems within range to be connected to the web, whether out in the field or at the workplace desk.
