6 Months of Security Links #2011

leave a comment »

I’m a regular curator of daily links, and like to give overviews of my collection of curated links and posts. This is partly as there are some good sources and articles in here and as I am working on a research project which I started based on a number of books I read.

I’m sure you’ll find something interesting in the items below – there are some gems in the list – and I dare to hazard the guess you might learn something you wanted to know. 🙂

Risk is something which can be difficult to evaluate for the average person, there is a lot of work which goes in to learning not to do the two things that people usually do when they are confronted with risk:

  1. Ignore

As always I read far more in 2010 than I blogged about, and most of the books I did blog about were treasures. I hope I inspired you to read at least one of them. And you have certainly noticed that I have added them all to the bookstore to make it easier for you to find out more about them.

LinkedIn Certificate Expired Again! #linkedin

with 3 comments

You would not believe it, last year today I wrote the article: LinkedIn Certificate Expired. And today it happened again, this time it’s not in a weekend.

http://www.linkedin.com uses an invalid security certificate.

The certificate expired on 06/07/2009 19:41.

(Error code: sec_error_expired_certificate)

Will they learn from this for next year?

Thanks to Ali for the heads up!

MyOpenID Second Factor

leave a comment »

MyOpenID has two additional features I hadn’t seen before. They have added Two-Factor Authentication and TLSCertificate Authentication.

Nice new features, gives me a reason to switch default OpenID provider.

LinkedIn Certificate Expired

with 8 comments

For all you LinkedIn users, have you noticed that you can’t login or re-authenticate? This is because the Security Certificate expired today.

http://www.linkedin.com uses an invalid security certificate.

The certificate expired on 06/07/2008 08:53.

(Error code: sec_error_expired_certificate)

It’s easy to call the guys from LinkedIn, which has Got A Billion Dollar Valuation and collected 53 million in the last round of funding, stupid.

This is a business risk, to mitigate this a simple calender item could be created which alerts at least a week before expiration. Naturally it would be better to have your own PKI system with which you could easily create a new certificate rather than rely on an external vendor for new certificate creation. Although some provide the facility to create a new certificate online. To have anything expire on any day other than Mon-Thu, preferably round 12pm localtime is really really bad management.

Naughty LinkedIn!
