Security Update for SQL Server

This month Microsoft released a rare patch for SQL Server. A Security Update to fix venerability within Reporting Services.

We'd urge you to check the bulletin list of susceptible candidate versions of SQL Server. Rather, since there are so many versions susceptible, scroll to the list of non-affected versions. If your install is listed here, breath easy. If not, this update's for you.

I installed and function tested the update on SQL 2008. It's straightforward and SQL Server needs a re-start to kick it in, which means an outage if you're applying this to a core business server.

This patch covers a venerability in Reporting Services. Through this loop-hole malicious code could elevate access privileges and gain control and cause some damage. The malicious code could be planted on a web site or in an advertisement. Looking innocent enough, it's the sort of thing anybody could trigger.

The link between an external web site or advertisement and your internal SQL Server is not spelled out in the MS documentation. However, Microsoft give this an "Important" rating, which means they know the threat exists. The patch software targets Reporting Services components, which implies; an environment with web based interfaces to Reporting Services would be at-risk.

The time has come to embrace the challenges and implement features like electronic payments WITH the requisite controls. Unfortunately we see a focus on the problem and not the solution. Electronic control systems can close fraud options that are available now. A recent article in New Zealand is a case in point. OpenEFT  would have prevented this fraud. The conclusion that Lawyers and clients should be careful with emailed instructions could have been ensure you have systems and policies in pla...

Shopify and WooCommerce gain eCommerce market share

According to BuiltWith a site measuring the top web sites and the technology used behind it the results for August show Shopify building to a 19% share of "Australian" eCommerce sites. There are a few holes here though as this uses geographical data and .au  domains. It is cheaper to use a .com domain though and many sites are hosted on remote servers. BigCommerce also saw some local growth with some better pricing and more attention to new sites. This came at the expense of old systems like osCommerce and ZenCart. The "Other" space has grown which includes Neto . Statistics for websites using Ecommerce technologies in Australia https://trends.builtwith.com/shop/country/Australia When looking globally at the top Million sites Shopify is dwarfed by WooCommerce.
