AWS tries to protect its customers from DDoS attacks with new service

Shield is available for free, by default, starting Wednesday

One of the big stories in security over the past year has been the rise of devastating distributed denial of service (DDoS) attacks that have hit sites and organizations like DNS provider Dyn, the BBC and the website of security journalist Brian Krebs.

Amazon Web Services is trying to help protect its customers with a new service aimed at mitigating DDoS impacts. It's called Shield, and the free entry-level tier is enabled by default for all web applications running on AWS, starting on Wednesday.

Werner Vogels, the CTO of Amazon.com, unveiled the service at AWS' re:Invent conference in Las Vegas. Automatically protecting its customers may help encourage businesses to pick Amazon's cloud over others, or convince businesses to migrate their web applications to the cloud. It's also a strike against companies like Cloudflare and Akamai, which offer DDoS mitigation services.

Shield Standard is aimed at protecting web apps from the overwhelming majority of common DDoS attacks at no extra cost. (For the nerds out there, Vogels said that it would block volumetric attacks like NTP reflection attacks, and many state exhaustion attacks.)

Companies that are concerned about more sophisticated attacks can pay for AWS' Shield Advanced service, which gives them a number of advanced capabilities. First off, they get access to an always-available hotline that they can reach out to when they need help with a DDoS attack.

That support will work with customers to develop custom mitigation for attacks that aren't covered by the standard service. For customers of AWS' load balancing and DNS services, the public cloud provider will also cap their costs while the attack is ongoing, so it's easier for them to weather the storm.

Shield is a part of the fleet of announcements coming out of re:Invent. Over the past week, Amazon has revealed a number of capabilities, including new infrastructure offerings, data analysis tools, AI-driven APIs and more.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
