Not shown in Fig. 1 are some elements of the network that complicate security efforts.
There may be a corporate firewall or network address translation (NAT) features that will
require communication between the building services staff and IT staff, but will also
provide greater protection against IT threats. There may be other external connections
from a trusted network that bypass the SR, i.e. a modem connection. Also not shown are
physical security implementation details.

Worm containment must be automatic because worms can
spread too fast for humans to respond. Recent work has
proposed network-level techniques to automate worm containment;
these techniques have limitations because there is
no information about the vulnerabilities exploited by worms
at the network level. We propose Vigilante, a new end-toend
approach to contain worms automatically that addresses
these limitations. Vigilante relies on collaborative worm detection
at end hosts, but does not require hosts to trust each
Questions have been raised about the social impact of widespread use of social networking sites (SNS) like Facebook, LinkedIn, MySpace, and Twitter. Do these technologies isolate people and truncate their relationships? Or are there benefits associated with being connected to others in this way? The Pew Research Center’s Internet & American Life Project decided to examine SNS in a survey that explored people’s overall social networks and how use of these technologies is related to trust, tolerance, social support, and community and political engagement.
If you wish to allow all connections for a particular network, add the network address to the list
and select the corresponding check box in the Trusted column. Otherwise, if you want to
remove a network address from the Trusted Zone, clear its check box.
If you want to allow all NetBIOS communications—to and from a network address—make sure
the corresponding box in the NetBIOS column is selected. To disallow all communications with
the network, just clear the NetBIOS and Trusted check boxes. ...
The main types of social networking services are those which contain category places (such as former school-year or
classmates), means to connect with friends (usually with self-description pages) and a recommendation system
linked to trust.
Safety and privacy concerns: Social media raise important issues in relation to identity,
trust, reputation and privacy, according to a recent IPTS survey among young people (Lusoli
& Miltgen, 2009) and other studies. The risks arising from using open online environments
are a bottleneck for the deployment of the full range of social media approaches in
