Draytek Web Content Filtering(WCF)
Web Content Filtering
DrayTek's Web Content Filtering (WCF) facilities enable you to protect your network and your users from web content according to your preferences. There are many reasons for doing this, for example:
|Reason to Block||Example|
|Unsuitable||Adult material for children|
|Undesirable||Time wasting sites for employees|
|Dangerous||Malware or virus-ridden web sites|
|Fraudulent||Confidiential data leaving your network|
As DrayTek WCF is performed by your router - your point of entry to the Internet - it is far more difficult to circumvent than software solutions installed on each client/PC or Tablet and applies to guests too.
DrayTek's Web Content Filtering can be applied to any device capable of accessing the Internet, such as Smart TVs, Tablets and Mobile Phones, which may not otherwise have filtering solutions available.
Blocking/filtering can be selective for certain computers, users or groups too, so that, for example, managers can have less filtering imposed than other users and time schedules can apply content filtering for specific time periods only (the facilities and granularity of this depends on the specific model of router selected).
Internet Control for familes and children
Whilst the Internet can be hugely beneficial to any family users, both for adults and children, there is also the opportunity for it to become distractive, over-consuming as well as risky. For children, a common use of control control is to block inappropriate content, such as web sites with sexual, violent or other adult-oriented content in schools or anywhere else that children might use the Internet. That's the inappropriate content, but even age-appropriate content can be undesirable. Facebook might be great for your teens, and CBeebies for your younger children, but not if they are supposed to be doing something else.
Many parents want to control access to the Internet, for example allowing access to acceptable web sites for specified times of day only. For your adult users in the home, you may want to block access to sites which have a high probability of being infected with malware. You may also wish to block your own computers from sending emails in case of trojan/zombie infection. There are infinite combinations of content filtering and firewalling you might want to impose in your home.
Staff Internet Abuse - A real cost to your business
The Internet provides your business with an effective, useful and often essential facility. Your staff can use it to find quick answers, liaise with customers, send and receive emails and many other productive tasks. Unfortunately, the Internet also provides the opportunity for mis-use. DrayTek products can help you restrict, control and monitor staff Internet usage.
Staff using your Internet facility for time-wasteful activities are costing you. Even more importantly these activities can put your businesses computers and network at risk. A recent survey of 10,000 employees indicated that 44% admitted to spending time on the Internet for personal use, for up to 2.1 hours per day.
Most staff are responsible and prudent with their Internet use and we always recommend a suitable AUP (Acceptable Use Policy) to be in place so that staff or any users of your systems know what they are and aren't permitted to use the computers for. This AUP can be re-inforced by DrayTek routers which can block specific content (either at certain times only or all times) and also block potentially harmful file/code types from being installed by rogue web sites. There are some staff who will make severe abuse of the Internet facilities - spending literally hours on personal matters or social networking sites.
Top 5 Personal Internet Uses for Employees
- Personal Email: Hotmail, Gmail, Yahoo etc.
- Intant Messaging: Skype, AOL, Yahoo etc.
- Social Networking: Facebook, Twitter etc.
- Buying: Using Amazon, Ebay etc.
- Multimedia : YouTube, iPlayer etc.
It's easy to let a 'quick visit' become a prolonged stay without realising and losing track of time. All of the above activities can be immensely time consuming and addictive.
What doesn't quite make the list but could be even more serious in its consequences is adult or illegal material being accessed in the workplace, as well as the higher likelihood that such sites are infected with malware which will then get onto your business network. There is also the potential to 'innocently' download software and install it on local PCs, unwittingly introducing spyware or trojans onto your network.
Introducing DrayTek Web Content Filtering
DrayTek Web Filtering allows you to block web content in six main ways:
1 - By matching keyword / specific sites
2 - By web site category (Subject to Subscription)
3 - By digital content type
4 - IP Filtering (Actually part of the firewall, along with many other security features.)
5 - Filtering HTTPS with DNS
6 - Network Level SafeSearch
Features 1, 3, 4, 5 and 6 of the above are included with the router. Feature 2 is included but requires an annual subscription to the external server, which keeps a real-time constantly updated database of web sites. More details of that later.
Features supported varies with router model; please check on specification for confirmation of Web Content Filter capabilities.
1. Keyword Matching URL Content Filter
In Keyword Matching you can specify a list of either banned (blacklist)) or permitted sites (whitelist). The DrayTek method is 'object' oriented, which means that you create lists of keywords or sites, can then group them and then apply them into specific user groups or time periods
Using a blacklist, all sites would be accessible by your users except those that match the keywords you specify. This would be useful, for example where there are specific sites known to be causing disruption or timewasting in your organisation such as social networking or webmail. The example below would allow access to all sites except the ones listed:
A whitelist, on the other hand, is much more restrictive on what your users can access as it blocks all web sites by default and then only allows access to web sites which match your keywords. This is useful when you really want to lock down your Internet access to only allow very specific web site access. The example below would block access to all web sites except those listed:
The URL blacklist and whitelist feature support varies with router model; Please check the specification of each product for details of keyword matching support.
2. Web Site Category (DrayTek GlobalView, powered by Cyren)
DrayTek's GlobalView is built into most of our routers and allows you to select specific categories of web site which your router will allow access to. For example, an office may wish to block access to social networking or other company time-wasting sites or a home user might want to block adult sites from their children. In public Internet access facilities, you might want to block various unsuitable categories.
GlobalView covers 64 separate categories which you can select as blocked or permitted. Every time one of your users attempts to access a site, the router automatically queries the central GlobalView server to ascertain its classification. This takes only milliseconds. If a site is blocked by GlobalView, according to the categories you have selected, instead of the requested web page, a warning message is displayed to the user (you can customise the message).
The GlobalView central database is continuously updated with new sites and changes to sites but also records normally legitimate sites which have become compromised or contain malware (a unique feature to GlobalView). Access to the GlobalView server requires an annual subscription. A free 30-day trial is included with all new routers so that you can try the feature out before subscribing. Scroll down the box below to see the 64 different categories which can be blocked by GlobalView, either permanently or at certain times of day/week according to your chosen schedule and for the PCs you choose.
GlobalView requires a subscription to the GlobalView server. This is a 12-month subscription available from your dealer. There is no additional licensing for the number of users you have; it is a flat fee based on your router model:
