Want to use AI and machine learning? You need the right infrastructure

Artificial intelligence (AI) and machine learning (ML) are emerging fields that will transform businesses faster than ever before. In the digital era, success will be based on using analytics to discover key insights locked in the massive volume of data being generated today.In the past, these insights were discovered using manually intensive analytic methods.  Today, that doesn’t work, as data volumes continue to grow as does the complexity of data. AI and ML are the latest tools for data scientists, enabling them to refine the data into value faster.[ Also read: Network operations: A new role for AI and ML | Get regularly scheduled insights: Sign up for Network World newsletters ] Data explosion necessitates the need for AI and ML Historically, businesses operated with a small set of data generated from large systems of record. Today’s environment is completely different where there are orders of magnitude more devices and systems that generate their own data that can be used in the analysis. The challenge for businesses is that there is far too much data to be analyzed manually. The only way to compete in an increasingly digital world is to use AL and ML.To read Continue reading

Firewall Rules – Priority and Ordering

Firewall Rules - Priority and Ordering
Firewall Rules - Priority and Ordering

Firewall Rules are one of the best security features we released this year and have been an overwhelming success. Customers have been using Firewall Rules to solve interesting security related use cases; for example, advanced hotlink protection, restricting access to embargoed content (e.g. productId=1234), locking down sensitive API endpoints, and more.

One of the biggest pieces of feedback from the Cloudflare community, Twitter, and via customer support, has been around the order in which rules are actioned. By default, Firewall Rules have a default precedence, based on the actions set on the rule:

Firewall Rules - Priority and Ordering

If two or more rules match a request, but have different actions, the above precedence will take effect. However, what happens if you've got a bad actor who needs to be blocked from your API, and you have other specific allow or challenge rules already created for their originating ASN or a perhaps one of your URLs? Once a Firewall Rule is matched, it will not continue processing other rule, unless you are using the Log action. Without a method of overriding the default precedence, you cannot easily achieve what's needed.

Today, we’re launching the ability for customers to change the ordering of their rules. Continue reading

Gnome3 Customise Shell Theme

I recently re-installed Ubuntu 1804 on my laptop and I though I would give the PopOS desktop theme from system76 a try. The verdict? It's very very nice. Next time I do a re-install or get a new laptop I think I will use PopOS which is based in Ubuntu anyway. Side note: If a System76...

BrandPost: 5 Steps to Get Ready for 802.11ax

It’s a mobile, cloud and IoT world. Whether it’s a workplace, a classroom or a dorm room, people are using a variety of devices beyond the usual phone and laptop combo—smart TVs, gaming consoles and fitness trackers, for starters. Offices, stores and manufacturing floors are outfitted with sensors that keep us safe, regulate the temperature, water the plants and run the production line. People use a broad variety of applications such as voice and video from their mobile devices. And expectations are at an all-time high. People will simply ditch digital services that don’t work. No one wants jittery presentations and dropped calls. The network experience must be flawless.To read this article in full, please click here

IDG Contributor Network: Can TLS 1.3 and DNSSEC make your network blind?

Domain name system (DNS) over transport layer security (TLS) adds an extra layer of encryption, but in what way does it impact your IP network traffic? The additional layer of encryption indicates controlling what’s happening over the network is likely to become challenging.Most noticeably it will prevent ISPs and enterprises from monitoring the user’s site activity and will also have negative implications for both; the wide area network (WAN) optimization and SD-WAN vendors.During a recent call with Sorell Slaymaker, we rolled back in time and discussed how we got here, to a world that will soon be fully encrypted. We started with SSL1.0, which was the original version of HTTPS as opposed to the non-secure HTTP. As an aftermath of evolution, it had many security vulnerabilities. Consequently, we then evolved from SSL 1.1 to TLS 1.2. To read this article in full, please click here
