Security for VOIP

Information technology has seen a major development in this decade that has created more innovative products to make communication faster and cheaper than we expect. Internet telephony or the (VOIP) voice over internet protocol is one of the major development that has made voice transmission more clear, fast and cheaper. Broadband service and fiber optics have facilitated the growth of VOIP technology and is expected to be used in a wider spectrum. There are a few threats or cautions like spamming, spoofing and identity threats that have been alarmed since the emergence of this technology.
1. (SPIT) Spam over internet telephony is a mix of telemarketing and spam. Calls are free or cost much lesser not just for customers but also for marketing companies. A large volume of VOIP calls and messages can pile up in your inbox which will be sent using automated programs. Also they will occupy large mega bytes of storage which can reduce the traffic of genuine and wanted messages.
2. Spoofing is a method of creating a mask or fake identity using the internet telephone. Since internet telephone use a MAC (Media access control) address for identification, spoofing of the MAC also possible. This can help hackers and attackers to make the customers believe that the call is from a known or trusted source. These calls can make the customers disclose personal information like account numbers, (SSN) Social security number and other authentic information.

phpBB released its new version. 3.0.5.
This release fixes numerous bugs since the 3.0.4 release, corrects style issues, fixing one very minor security bug as well as increasing performance and scalability again. They also added a few new minor features.

New features and important changes are:
* Added and refined CAPTCHA options to better protect against new version of CAPTCHA crackers.

* Performance improvements for native fulltext search.
* Added a new search option. The admin can define the maximum number of words allowed to search for. This option gives control about the maximum search load.
* Search indexing should no longer stall for some installations.
* Conflicting files are able to be downloaded now within the automatic updater for manual inspection.
* The database updater now checks for an incompatible database schema in case the database version got updated. The admin will be notified about possible solutions and repair scripts.
* We now set the connection encoding for MySQL versions 4.1.0 to 4.1.2. This may fix some conversion issues with special characters.
* Language pack authors now see errors/notices within their language pack if they enabled DEBUG_EXTRA.
