Incre<strong>as</strong>ed Security<br />
for P<strong>as</strong>sengers –<br />
including online<br />
Nicol<strong>as</strong> Hunloh, Team Leader Internet,<br />
Düsseldorf International Airport<br />
The air transport hub of Flughafen Düsseldorf handles over<br />
20 million p<strong>as</strong>sengers per year, making it the largest airport<br />
in North Rhine-Westphalia. 70 airlines operate here, serving<br />
more than 190 destinations. Located in one of Europe’s<br />
strongest-performing economic regions, with 18 million<br />
people living within a radius of 100 kilometres, Düsseldorf<br />
International plays a key role in fulfilling the mobility needs of<br />
private individuals and businesses in the federal state of North<br />
Rhine-Westphalia and the south-e<strong>as</strong>t of the Netherlands.<br />
Furthermore, <strong>as</strong> the largest single employer in Düsseldorf<br />
with a workforce of around 19,700, the airport h<strong>as</strong> a major<br />
impact on the jobs market in NRW.<br />
As traffic h<strong>as</strong> incre<strong>as</strong>ed over recent years, the corporate<br />
website h<strong>as</strong> had to adapt and grow to meet the demands<br />
of p<strong>as</strong>sengers <strong>as</strong> well <strong>as</strong><br />
those who are picking<br />
them up from the airport<br />
and other target groups.<br />
These users visit the site to<br />
check flight times,<br />
to find out about<br />
local conditions,<br />
to reserve parking<br />
spaces, to retrieve<br />
general information<br />
about the airport,<br />
and much more<br />
besides. The website<br />
is thus a main<br />
point of contact for<br />
By undertaking regular<br />
security checks, including<br />
around 11 million<br />
its online platforms,<br />
users per year.<br />
Düsseldorf airport<br />
upholds consistently high<br />
security standards.<br />
Various extranets<br />
provide B2B partners<br />
and customers<br />
with helpful<br />
tools. Data that is<br />
stored there requires<br />
secure protection.<br />
Flughafen<br />
Düsseldorf GmbH<br />
therefore took the<br />
decision in 2012<br />
to submit its main<br />
corporate website<br />
<strong>as</strong> well <strong>as</strong> those<br />
of its subsidiaries<br />
to an extensive security check. Their<br />
search for a professional, flexible and<br />
reliable service provider quickly brought<br />
them to secunet.<br />
For the operator, it is particularly important<br />
that the standards which are<br />
rigorously adhered to in the everyday<br />
working environment of the airport’s offline sector (where<br />
security is at a premium) apply equally to its website. Because<br />
even data on p<strong>as</strong>sengers and partners requires the protection<br />
of a highly secure and efficient infr<strong>as</strong>tructure against<br />
externally launched attempts to gain unauthorised access.<br />
The secunet team therefore set about identifying potential<br />
vulnerabilities using a detailed penetration test and applying<br />
recognised standards with particular reference to OWASP<br />
Top 10 2012. In order to avoid overloading the server infr<strong>as</strong>tructure<br />
during the procedure, the tests were conducted<br />
during the low-traffic period between 11pm and 6am.<br />
