Do You Have SSL Configured Correctly?

Do You Have SSL Configured Correctly? Let me start by saying that "correctly" means "best for you". There isn't a single correct answer, although there are certainly some "don'ts" that apply in every situation.

This information is not about whether to use SSL, and is mainly for your systems folk (or hosting company), but do read on and perhaps gain a better understanding.

Ivan Ristić recently announced the SSL Server Rating Guide (draft 10, 21 July 2009) and an associated online assessment tool called the Public SSL Server Database. These had reminded me to post my comments last Tuesday about the slightly related Colour Overload with IE8 Tab Grouping.

The SSL Labs' resources describe, and allow you to check, the SSL configuration of your own, or any other public site that has SSL enabled. The checks span the certificate and three categories of web server configuration settings. Previously, it needed more specialist tools that most people wouldn't have the time or inclination to use.

The rating guide contains much useful information, but will be too detailed for many people. However, do read the "Minimal Configuration Requirements" and pass these on to appropriate person responsible for the configuration and operation of your own web sites. Not every site needs an overall rating of 73 or 85 or whatever. You'll see in Table 6 of the guide, an idea of what might be suitable for a range of web site types.

After all, your competitors, and some customers, have probably already checked your site.
