    Declaring Security

    • 11 Comments
    Recently, a number of people have asked me what I think about Mozilla’s Content Security Policy draft spec. Back in January, I went on record as being someone who thinks that CSP is a good idea. CSP is a mechanism for declarative security , whereby a site communicates its intent and leaves it up to the user-agent to determine how to enforce it. There are a number of benefits to declarative security mechanisms: Reduced compatibility risks. Because sites must opt-in and declare what, if...

However, because Flash is an add-on and not part of standard HTML content, browsers have not been able to delete Flash cookies the same way they delete HTTP...

    Greetings, I’m Russ McRee of Microsoft’s Online Services Security & Compliance Incident Management team. My team serves as incident handlers for the various types of attacks our online services face. High on the list of incidents we handle are cross-site scripting attacks.

    Sub-pixel Rendering and the CSS Object Model

    • 9 Comments
    With Windows 8, you have an unprecedented choice of devices for browsing the Web, from large desktop screens to small slates. In order to accommodate this range of devices, the browser must be able to scale and layout the Web at many different screen sizes and dimensions.
