Second Life Security Flow through QuickTime
Wed, 09 Jan 2008 10:30:39 +0000
Adobe recently announced the third version of the company’s Flash Media Servers: Flash Media Streaming Server 3 and Flash Media Interactive Server 3. The two servers come with a lot of improvement but the one thing that really catches the eye stands in the built-in support for H.264 and, of course, a huge price drop in the Interactive Server that comes with intelligent caching. What is really special is that this price cut comes from $45,000 to just $4,500. This has to be one of the most incredible price cuts in some time now and it is quite interesting that it comes from Apple.
Sting as it could mark a significant change when it comes to running a streaming media servers, as this might not be a link necessarily done with Brightcove, YouTube or various other companies like Disney or CNN. Besides taking off $40,000 from the original price, we also have to say that the assembly of an Adobe based Flash media server in such a way that it can service thousands of connected clients at the same time can be done a lot better and faster than in the past. To put it simple, for the price a company had to pay for one Flash Media server, we can now purchase 10, making one an origin server ant the rest edge servers. The new media servers from Adobe run on AMD or Intel based machines that come equipped with Windows Server or Red Hat Linux. The real problem is no longer the price of the equipment thanks to Apple, but the price paid on high-bandwidth storage and networking infrastructure. The next step is taking a look if there will be any company that will be bold enough to try a streaming server similar to that of YouTube and if so, if there will be some sort of success.
Which Wireless Security Is Best?
Sat, 21 Apr 2007 06:49:46 +0000
When using Wi-Fi wireless networking, security can be a
problem. By default, these sytems will often have no security applied, allowing any station to logon and access the network resources. Obviously this is less then ideal! We explore some of the wireless security mechanisms below and explain their protective value.
Changing the SSID
The service set identifier is a name used to identify each wireless network. While changing this from default is absolutely essential, this act doesn’t improve the security of the wireless network. Any wireless adapter nearby will be contacted by an unsecured
base station and transmit the SSID automatically alowing them to connect.
MAC Address Filtering
Mac stands for Media Access Control. Limiting access to your wireless network via MAC address control reasonably good method for very small networks. You can find the MAC address in your network adapter’s configurations settings. However this is far from the strongest form of wireless protection. MAC addresses of wireless adapter’s can be changed in software, and the MAC address it’s self is transmitted in the clear.
Wired Equivalent Privacy was one of the first encryption methods with wireless networking, but it was shown to have fundamental flaws.. If your serious about wireless networking security, do not use this standard.
Wi-Fi Protected Access, Pre-Shared Key is reliable system for securing a small wireless network of less then ten users. each user is supplied the same SSID and passphrase to utilize the strong traffic encryption of this system. The drawback of this is approach is that every user of the network must use a new password every time the user is removed from the network.
802.1X and RADIUS Authentication
While small Wi-Fi networks are manageable with a single access password for all users, for larger networks it is essential to roll out a sever that authenticate multiple user and allow and allow you you to ad and remover users as needed. This requires 802.1X standards for Network Access Control and establishment of a RADIUS server (Remote Authentication Dial In User Service), which allows maintenance of users and individual passwords.
WEP Has Been Cracked Again
Thu, 05 Apr 2007 06:33:24 +0000
Well the cat has been out of the bag for a while now that WEP encryption has been very easy to crack.�
Guess what? It just got even easier.
It is no secret that WEP is still widely used by many home network admin’s� and this just proves once again why it shouldn’t be. When WEP was first cracked back in 2001 it took roughly 4 million packs of data to retrieve the security key. Not long after more hacks where discovered that could do it in a lot less time, well hours instead of days.
Now at the Darmstadt University of Technology in Germany they have managed to extract a 104-bit WEP key in a matter of seconds. This means that you could crack a WEP wireless network within the time it takes you to drive out of range.
This should be a message all people that have a wireless network and are still using WEP encryption. WPA- pre shared key is just as easy if not easer to use then WEP and is 1000% more secure. There is no excuse anymore for running WEP. WPA has been around long enough that almost all equipment will support.
For my wireless network I use WPA and I get my keys from . It will give you a one off cryptographic strength password which is 100% uncrackable at this point in time.�
For added security the page that you get the key from is also encrypted so you can feel safe that no one will ever know you new password.
