Wenig beachtet hat in der vergangenen Woche die European Network and Information Security Agency (kurz ENISA) ihren aktuellen Bericht zur Internetsicherheit veröffentlicht. Darin geht es in diesem Jahr schwerpunktmäßig um das Thema „soziale Netzwerke“:

Experiencing online social networking sites (SNSs) has become one of the most
popular activities carried out on the Internet. The modern way of staying in
touch with business and personal contacts is to be present on social networking
sites and to communicate using e-mail and other digital tools. The social
networking phenomenon has registered an exceptional growth trend and there has
been a widening in terms of users profiles involved in such activity (1),
affecting and changing consequently the way people get in contact, meet,
communicate and share opinion, information and ideas. This phenomenon is rapidly
evolving not only in relation to the audience, changing its demographics, but
also in relation to the way the audience itself can experience social networks.
Besides traditional computer-based access, users are now able to access social
networks through their mobile phones.

Im folgenden werden neue Daten zur Verbreitung von sozialen Netzwerken in Europa dargestellt:

Of the around 283 million European users, 211 million of them, aged 15 and older
who accessed Internet via a home or work computer, visited a social networking
site. The largest public is represented by the UK with 29 million visitors,
reaching 80% of the countrys total Internet audience. Among all social
networking sites, Facebook has gained a top position throughout the majority of
European countries. A research conducted by comScore  stated that, of the 17
European countries included in the study, Facebook played a leading role in the
social networking category in 11 of them in terms of unique visitors. The
sites largest audience is in the UK with about 23 million visitors followed
by France with about 14 million visitors. The only countries in which Facebook does not hold the No 1 or No 2 position are Germany (No 4), Portugal (No 3) and Russia (No 7).

Abschließend geben die Autoren den Nutzern der Netzwerke ein Regelwerk an die Hand; in Form goldener Regeln. So sollen Nutzer Spitzennamen verwenden und sich nach einer Sitzung am Rechner immer abmelden. Dem Netzwerk sollten sie dabei nicht erlauben, die Zugangsdaten im Cache zu speichern

Golden rules:

1. Consider carefully which images, videos and information you choose to publish

2. Never post sensitive information

3. Use a pseudonym

4. Do not accept friend requests from people you do not know

5. Verify all your contacts

6. etc.

Nicht ganz uninteressant erscheint in diesem Zusammenhang auch ein Artikel von heise-Online aus der vergangenen Woche:

Soziale Netzwerke sind „wahre Fundgruben für Ermittlungs- und Fahndungszwecke“. Das schreiben die Polizeidozenten Axel Henrichs und Jörg Wilhelm in einem Aufsatz der aktuellen Ausgabe der Zeitschrift Kriminalistik. Analog zum verdeckten Ermittler (VE) müsse die Polizei verstärkt virtuelle verdeckte Ermittler (VVE) einsetzen.
