Bayesian Spam Filters - How Do They Work?

Bayesian spam filters, which are a type of scoring content-based spam filters, analyze the contents of the mail, and calculate the probability of the message being spam.
Bayesian spam filters, which are a type of scoring content-based spam filters, analyze the contents of the mail, and calculate the probability of the message being spam. It builds up a list of characteristics of elements that are typically spam as well as good emails. The advantage of the Bayesian spam filters is that they build up the list of characteristics themselves, and do not depend on the manually built list.
Bayesian spam filters more or less try to emulate how you personally identify your spam emails. One look at an email tells you whether the email is genuine or spam. The probability that you will characterize a good mail as spam is zero . Ideally, it would be great if spam filters do work in the same way. At least, the Bayesian spam filters are trying in this direction.
Spam Filtering
Suppose that the word textile often appears in your legitimate mails, but never in your spam mails, then there is zero probability of the word textile indicating spam. On the other hand, the words Nigeria and lottery quite often and at times most exclusively, appear as spam - made famous by the 419 scams out of Nigeria and elsewhere in Africa.
For Bayesian spam filters, these two words Nigeria and lottery have every probability of being found in spam emails - as much as 100 percent.
Whenever you receive a new message, the Bayesian spam filter analyzes it, and calculates, by using the individual characteristics, the probability of it being a spam. If it so happens that your message contains both words, textiles and Nigeria or lottery , the Bayesian spam filter cannot ascertain whether the message is a genuine one or a spam. It will further analyze other characteristics that will allow it to assess the probability of classifying the message as either, spam or legitimate.
Bayesian Spam Filters - Adapting Automatically
Once you have classified the message, as shown above, it can be used to further train the spam filter. This is how it works. In the above scenario:
If the message is analyzed as being spam, then the probability of the word textile indicating legitimate mail is lessened. If the message is analyzed as being legitimate mail, then the probability of the words, Nigeria or lottery - whichever was used - needs to be re-analyzed and re-considered as spam.
The advantage of Bayesian spam filters is that they self adapt by learning from their own decisions, as well as the user s decisions - if made manually. This automatic adaptability of the Bayesian spam filters is excellent for individual email users. Most spam emails have very similar and at times identical characteristics, whereas the characteristics of legitimate mails are different for each individual.

Extending The Capabilities Of Performance Testing Tools

Introduction:
Performance testing has become an integral part of Client/Server and Web environments today. With performance engineering comprising performance testing tools, the testing cycle time can be reduced significantly. The capacity of existing performance testing tools has limitations in supporting various protocols. This white paper indicates that Performance testing tools offering wider coverage without much investment are the need of the hour.
The SituationA performance testing tool can simulate internet user behavior only on http protocol and can be enabled for multi protocols as well by plugging-in an ActiveX Component or a Java Class programming language code establishing a TCP/IP Connection within the script of the tool. Common Protocol Support:
http
https
Telnet
FTP
While with licenses for the http protocol, the compact version of existing performance testing tools can only support the http/https; additional licenses are required to be purchased for supporting other protocol(s). Enabling tool to support other protocols:
A particular performance testing tool can be made to support a group of desired protocols by setting up a server / application specific development process. This performance engineering is a complex process involving the following steps Steps involved:
1. Deciding the transactions.
2. Setting up a packet sniffer for capturing the packets traveling between the user machine and the Server.
3. Executing the transactions manually.
4. Saving the details of the captured packets.
5. Analyzing the flow of packets starting from packet
6. Determining the user input in the packets.
7. Parameterizing the user inputs in the packets.
8. Creating functions to simulate the packet flow.
9. Creating an instance for that component inside the script of the tool for plugging-in the component within the tool.
10. Calling functions from the script.
Analyzing Packets:
Analyzing packets is the major part in the process requiring tedious coding and decoding.
Phases in Analyzing:
Six phases in the process of analyzing packets -
Separating Headers and Data portions in the packet.
Analyzing the Header packet.
Analyzing the Data packet.
Determining the constant and variable bytes in the data specific packet, both are usually in HEX String.Repeating the process with various user inputs getting accustomed with the bytes transferred.Checking if any data for the previous response is transmitted with the next request.
Ethereal - Network Protocol Analyzer is very helpful sniffing tool to see new variable bytes by simulating traffic from code detecting several protocols, such as:
H323 / Q931 VOIP Protocol.
ICQ Protocol.
Java RMI.
Remote Procedure Call.
IEEE 802.11 wireless LAN.
Ethereal has a rich display filter language and can view reconstructed stream of a TCP session.
Creating the PSEUDO Client:
While designing the client, the transaction is divided into stages with separate functions for every user interaction and server reply.
Separate functions are required for:
Sending the first request and receiving the first response.
Extracting data from the response to append in the second request.
Sending second request and receiving second response.
Similar process must be followed for the remaining traffic. Maximum number of variables must be created for keeping track, with the possible constant fields stored as variables. Following is the screen-shot of an ethereal record of a simple http transaction.
Integration:
Finally, the client component is integrated in the tool, which requires creating an instance of the component and calling the function with different parameters i.e., user inputs, which allow the desired protocol to be supported by the tool. Process Pros:
1. Perfect simulation with perfect packet analysis.
2. Frequent update for new plug-ins for the new protocols.
3. Cost effective.
Process Cons:
1. Difficulty in decoding.
2. For encrypted applications the process cannot be implemented.
3. For Oracle NCA protocol the process can be implemented only if plug-in is readily available.
Conclusion:
Performance testing can demonstrate the system meeting performance criteria. The later a performance defect is detected, the higher the cost of remediation. This is true in the case of functional testing, but even more so with performance testing, due to the end-to-end nature of its scope. It is always helpful to have a statement of the maximum number of users likely to use the system at peak times. Performance testing almost invariably concludes that it is the software rather than hardware that contributes most to bottlenecks in processing data.

Fast and Reliable Recovery of Microsoft Office Documents

What would you value most in a data recovery solution should you lose an important document? Would it be speed, convenience, or ease of use? These things surely matter for all kinds of computer software, but data recovery has one specific demand that outweighs everything else by a huge margin. This factor is reliability of the recovery. Microsoft Office documents store results of many hours, days or even years of work of practically all office employees and most people who use their computers at home. Microsoft Word dominates the market of word processors, and most if not all documents are stored in RTF and its proprietary DOC formats. Microsoft Excel and its XLS file format dominate spreadsheet market. Most presentations are created in Microsoft PowerPoint and stored in PPT files, and most charts and drawings are drawn in Microsoft Visio and saved as VSD files. Combined, files in these formats occupy significant space on the users hard drives, and represent hours and hours of work, much more than any other file format. In an unfortunate case of hard disk crash or file system failure, what would you try to recover the hardest? Would it be a set of software products such as Windows or Office itself, which you can easily re-install from the original CD or DVD, or would it be files and documents you spent your personal time working on? Unless you have a fresh backup of your documents somewhere, the documents are impossible to simply re-install. If you have a recent copy of your Office documents, that s great! But what if your backup is several days old, and you ve put a lot of work into these documents? Or even worse, what if you don t have a backup at all? Recover latest versions of your deleted documents even after a hard drive failure with DiskInternals Office Recovery securely and reliably. Unlike general-use undelete and data recovery tools, DiskInternals Office Recovery strongly benefits from being designed specifically to handle documents stored in Microsoft Office format. General-use recovery products scan the computer s file system in order to locate files that were deleted or corrupt because of a hard drive failure. However, they frequently fail to work properly if the file system itself is damaged, which happens a lot after hard drive failures. DiskInternals Office Recovery scans entire surface of your hard drive in order to locate all Microsoft Office documents that are still there. In order to find the documents, it uses a set of signatures that are characteristic for the Office file types. The file system is also scanned in order to retrieve the names of the files. The results of disk scan are matched against information contained in the file system, and you are presented with a complete list of all Microsoft Office documents that are on the disk and that are still possible to recover. Quite often you don t want to see the list of all Microsoft Office documents that were ever saved on your computer. There s no point in spending time scrolling through an endless list of files if you just need the latest revision of a PPT presentation or an XLS spreadsheet, but you need that document right away. DiskInternals Office Recovery offers an extensive set of filters allowing you to display only the files that you need with just a few mouse clicks. If you need a DOC file that you know you worked with today, you simply activate the File Format and Date filters, and only the Word documents that were modified on this day will be displayed. If you don t remember the name of the file, but know its title or the person who created the document, the Title and Author filters will show you those files. Similarly, if you only remember a line or even a few words of text from the document, you can instantly locate that particular file by activating the Text filter. With full document preview in the free evaluation version, there are no worries or surprises in buying DiskInternals Office Recovery. Download the free trial version from www.diskinternals.com and see for yourself that it is fully capable to do the job!
