6 Optenet PC. User Guide 1 INTRODUCTION 1.1 Highlights Filtering over 99% effective. Error rate less than 0.1%, eliminated completely through the Contributions service. The most advanced technology: databases of websites, Semantic Analysis Engine for online content blocking, heuristic analysis of executables, content-based protocol identification, etc. The filters do not affect communications; it takes less than a millisecond to analyze a web page. Automatic database and program updates. Reports on all filtering processes. 1.2 OPTENET PC Web filter The web filter prevents access to undesirable Internet content, such as pornographic websites, dangerous file downloads, instant messaging servers or P2P. The Web filter is responsible for capturing traffic entering and leaving the PC. In addition to identifying the type of traffic, it requests the relevant integrated service for analyzing, monitoring or tracing the content, ensuring that browsing is safe and based on the configured parameters. It is based on semantic analysis of website content and lists of sites that have been placed in various content categories. The lists are updated every ten minutes. Semantic analysis verifies, independently of whether the website is included on a list, whether the page contains any text with inappropriate content, in which case the user is blocked from accessing it. 1.3 Protocol Filtering Protocol filtering detects connections and identifies the protocol type, performing various actions depending on the configuration. This allows users to control applications like Instant Messenger, P2P, Chat, and Newsgroups. OPTENET 6

7 1.4 Effectiveness OPTENET PC possesses the most effective security service technologies.

The filter lists contain pages from all languages. Additionally, the Semantic Analyzer is trained periodically with pages from around the world, enabling it to detect pages in all languages. To achieve as high a level of effectiveness as possible (99%), for certain languages (e.g. English, Spanish, French, Dutch, Portuguese, German and Italian) a broad collection of pages is put together to train the Semantic Analyzer. 1.6 Browsing speed when using OPTENET PC The web filter is extremely fast and, as a result, the user does not notice it working.

38 In case P2P protocols are set to be blocked, if the web category P2P Servers is not being blocked (see [WebFilter >> Configuration]), you will be asked to also block this type of web sites: Instant Messaging This option is used to control the use of instant messaging applications (e.g. Microsoft MSN Messenger, Yahoo Instant Messenger, ICQ 5.0, AIM), used to send messages and share files in real time. In case IM protocols are set to be blocked, if the web category Instant Messaging Servers is not being blocked (see [WebFilter >> Configuration]), you will be asked to also block this type of web sites: This option is used to control the use of accessed through the protocols POP3 (port 110), SMTP (port 25) and IMAP (port 143).

In either case you can establish exceptions to the above rule by entering specific ports or range of ports to be blocked or allowed, as applicable. OPTENET 39

40 6.8 Reinforcing the blocking Sometimes, there is a parallelism between web categories and families of protocols: Protocol P2P Instant Messanging Chat Web Category P2P Servers Instant Messaging WebMail Chat etc That is why, whenever you configure the filter to block any of those web categories, you will be asked if you wish to also block related protocols to reinforce the blocking (if those protocols are not set to be blocked yet). In a similar way, whenever you block a given protocol, if the analogous web category is not being blocked, you will be asked if you want to also block related websites. Eg. If you do not want that a given profile can use applications based on protocols, you will be asked to also block webmail sites for this profile. OPTENET 40
