After being subjected to an automated spambot email attack which lasted one week, IT staff at Perisher Resort decided to look for a new security solution.

Thousands of daily emails from an unknown source were sent to Resort email addresses.

The company operates more than 100 ski slopes in Perisher Valley, Guthega, Blue Cow and Smiggin Holes. During the peak winter season its network activity increases by 90 per cent due to the amount of users and devices accessing the network.

Perisher Resort's senior network and systems administrator, Wayne Grixti, said that after conducting a pilot programme, it selected Imperva’s Incapusula Web application firewall (WAF) offering.

“We chose the service because of its minimal management overhead and ability to work in our existing environment with no impact on network speeds,” he said in a statement.

“Our commercial operations are extensive, and in peak season trading conditions we need to ensure that the influx to our networks is protected and meeting payment card industry [PCI] compliance requirements.”

According to Grixti, the resort’s websites and applications are better protected against malicious automated attacks such as SQL injection. The software has also reduced network management time for IT staff.

In addition, Incapusula WAF generates PCI compliance reports which help IT and management staff in identifying areas of compliance prior to bank audits.

Grixti added that caching techniques have resulted in additional cost savings by reducing website bandwidth usage and lowering Web server utilisation.

Is it just me, or does this article not address the opening issue - a spambot "avalanche"- in any way? No mention of how the new security solution resolved the spambot attack, no description of the process used, no details of the results of the intervention. No commentary along the lines of "This happenened in the week of <date range> and after implementing <solution> it took just <n> days to reduce/remove the spambot threat etc etc etc."

Please could we see some real journalism, instead of a thinly-disguised advertorial for Incapusula [sic] ?

BigAl, they needed to put something season on the site, and we all love the snow, this seemed a great idea.

Perhaps the next article will be
"4G at Perisher, more snow to come" Telstra improved the mobile reception at Front Valley today as soon as it was turned on, the snow came. 20cms of snow feel whilst the 4G users were reveling in the light of this upgraded service. Before 4G only 30cm of snow had fallen, now 4G is on the natural base is back to 50cm and usable.
