Leap Year, Security and You

  • [アーティクル]

imageSecurity – CIA – Confidentiality, Integrity and Availability

What does CIA have to do with Leap Year?

And what does this have to do with Azure Security?

 

Consider the following:

  • Most cloud applications use UTC, which means on Feb 29th it might be some other time in your time zone
  • Leap Year bugs can be found anywhere, using any programming language
  • Because of this, Leap Year bugs have caused major service outages in the past (the “A” in CIA)

What are the two most dangerous Leap Year bugs:

  • Adding or subtracting years in C/C++
  • Declaring an array of values for each day of the year

It’s not too late to address these issues.

If you want more information on getting your code ready for Leap Year, check out the article Is Your Code Ready for Leap Year? on the Azure.com blog.

Thanks!
