Meltdown, Spectre and “Cloud Myths”

Meltdown and Spectre logos

With the news, impact analysis and resolution of the Meltdown and Spectre fun still ongoing, it’s fair to say there’s been a few difficult discussions ongoing worldwide about how to resolve the issue but there’s also been the fair share of #fakenews making its way around that could be considered “Cloud Myths”.

Without going into the details too much of Meltdown and Spectre (because there’s much more intelligent security teams publishing details about that), let’s address some of the Cloud Myths:

“These updates are going to cause me unacceptable downtime”

AWS, Azure, GCP and others have all been completing patching and rolling reboots for their infrastructure (or will do so soon) and additional patching may (depending on your platform) be required for your instance level Operating Systems with additional reboots.  Unfortunately, there’s multiple complaints of those reboots meaning downtime to users.

2017: The year of browser certificate warnings?

With the world rapidly moving towards a “HTTPS by default” approach, Mozilla reporting over 48% of webpages in Firefox being loaded via HTTPS and Google now serving 85% of their traffic over HTTPS the web is undoubtedly becoming more secure for transport (in one way and does not necessarily mean more secure overall), however it’s looking likely to be a rougher road to HTTPS than it’s been in the past.

Starting January 2017 (or whenever Chrome 56/Firefox 51 rolls): Part 1

Users in Chrome and Firefox will start to see sites using WoSign and StartCom Certificates getting Certificate Warnings as Google moves to distrust the organisations issues certificates in response to “WoSign knowingly and intentionally misissued certificates in order to circumvent browser restrictions and CA requirements” and attempting to “mislead the browser community”. Firefox is also following the same process

Starting January 2017 (or whenever Chrome 56/Chrome 51 rolls): Part 2

Performance, Availability and Security for success

When designing for critical applications, such as e-commerce sites or applications, where Performance, Availability and Security influence revenues, it is important to optimise at multiple points for success.

Location, Location, Location

With an ever increasing number of Data Centre locations and providers to choose from, it is generally possible to keep data and application systems within the same continent as users when working on a regional market, sometimes even within the country. Even for global applications, whilst the increase in legal complexity may introduce challenges for some markets, it is still possible to provide your users with a highly performant site.

One of the methods to achieve this is by using a Content Delivery Network (CDN) to serve your site from multiple locations worldwide, which (given the choice available of providers) likely includes from a Point of Presence (POP) within the country or countries of your target market.

CDNs: Content Delivery No-brainers!

With site loading times so critical for conversion of visitors to purchases and its use by Google as a signal in their search rankings, having optimal performance for your site’s users is very important to not just the popularity of your site, but also the success of your business.

CDNs – Who, what, where?

CDNs (or Content Delivery Networks to give them their full name) run multiple servers in multiple geographic locations with plentiful and high quality networking connections and compute resources. These can, depending on the company and their business model, run into the hundreds of thousands of servers, in hundreds of locations, with multiple Terabits (1,000 Gigabits) of connectivity.

Why all organisations should provide (and all consumers should demand) HTTPS applications

Security has been a hot topic for many years and when talking with customers about a multi-layer security design we are often recommending TLS (Transport Layer Security) as one of the basic components. This is often followed by more detailed questions about the benefits, costs and implementation compared with other, more discussed components which are front of mind for CSOs/CTOs. Below are some of the most common reasons for and myths against deploying TLS for your environments.

Pro: Performance and SEO benefits

Google has long said that speed is a ranking factor but did you know they are now using HTTPS as a ranking signal? As part of your Search Engine Optimisation strategy, why not add an easy additional boost to your environment using HTTPS, which gives the two fold benefit of ranking increase for simply using HTTPS but also a potentially significant increase for performance and reduce the time needed to load your pages via the use of HTTP/2. You can compare this using various tools.

Pros: Encryption and Authentication of your site

HTTPS when used correctly allows all website content to be securely encrypted in transit, meaning any malicious network devices between the user and the secure hosting environment supporting the website or application cannot access your data “on the wire”, helping to keep information such as Usernames/Passwords/Emails secure and private. In addition it allows authentication of the website/application to the end user, allowing them to identify that the site they are visiting is not being spoofed or maliciously edited (such as by rogue Wi-Fi network hotspots inserting advertising or malicious redirection).
