Re: [linux-5] Ways to counter DDoS for TOC

Hey,

At the risk of sounding self-promoting, the company I work for has a global network with a POP here in Singapore that is much more capable of handling these things.

All servers/cloud instances come with a 1Gb port, and we're used to handling ddos attacks. However, like sk said, a typical response to these attacks if they threaten infrastructure or cause increased costs for the customer is to shut off your port to stop it and hope they give up.

For larger customers, they usually want to stay up, so responses can involve moving to dedicated network infrastructure, splitting off into different instances often, etc. Sometimes the attacks come from certain transit providers or regions and those can be shut off to help mitigate it, but if it truly is very distributed, it's just very hard to differentiate between a real request and an evil request.

However, with a larger provider like us, we have more capacity to handle such things, so it raises the bar in how aggressively they have to attack you.

Our network VP posted a technical perspective on the twitter DDoS you might find interesting (http://www.voxel....­).

We don't have shared hosting solutions here in Singapore though, so the cheapest thing we offer is our non-shared 1 core, 2gb cloud offering (http://www.voxel....­).

But, if you really are having issues, I can try to help. Like I've mentioned to a couple other people at some other local meetings, we would like to get more involved in local tech community here, and part of that is sponsoring local startups and companies. I can give you at least a free month or so on a cloud instance and you can work with our guys here to see if it does anything to help. Just shoot me an email if you want to try.

Cheers,

Afternoon,

Best option is to go with offshore hosting like US or UK with large amounts
of burstable bandwidth that can handle such DDos and Brute force attacks. No
firewall or softwall will stop a direct hit to most providers. 

Singapore is far too expensive to buy, 1 - 2 GB Burstable Lined to be able
to manage with such attacks.

Softlayer and theplanet maybe the best option for susceptible websites.

Regards

Greg

anyone able to suggest some solutions for this? They are currently on shared
hosting. Will moving to VPS hosting be sufficient, or is a dedicated server
required? And are there any personal recommendations?
If not already done, IP-banning via a firewall can be used if the site is
hosted
on a VPS or dedicated server. It won't completely solve the issue, but it
should
mitigate it a little.
