The last week at Dreamtilt has been a challenge. It began with the failure of our main dns server, progressed onto someone hacking our voip server and then a brute force attack on our sip router which slowed our entire system to a crawl. All good fun. We have a painted target on us for one reason or another for this week. No doubt next week it will be someone elses turn for fun!
As a result we have looked at 2 new dns servers with increased security, applied new security measures to our voip, and restrictions on external traffic into our network, This week has made us realise just how nasty the Internet can be. However, as always there is a silver lining and that is we have certainly learned how to identify these attacks better, respond to them quicker, and hopefully with the assistance of our upstream provider block such attacks. It has also made us rethink our understanding of the network and improve critical parts. It still amazes me that there are people out there who seem to have nothing better to do than totally ruin businesses that run on the Internet and waste precious bandwidth on futile attempts to hack systems. If only these people spent more time improving the net rather than trying to dismantle every part of it illegally – just imagine the good that could be achieved.
Instead they turn their efforts to trying to break small local Internet Service Providers with way less technical and bandwidth budgets that the larger companies have. Well thanks to you unknown attackers for making us stronger and more aware. A valuable lesson was learnt!
