Purpose

Examine a bunch of browsers, existing Firefox Add-ons, and web services to generate a report that describes:

  • Which capabilities each has
  • A summary of where each is different/unique
  • Some conclusions about which aspects seem most innovative and interesting that we might want to consider for Firefox

Research

General capabilities

Malware Detection

  • Prevent malware attacks
    • Tell me if a download is suspected malware (FF3)
    • Using virtual machine techniques (GreenBorder)
    • Real-time with behavior-based profiling algorithms (Finjan SecureBrowsing FF extension, Haute Secure)

    • Notification whenever downloading or installing software (FF2)
    • Warn me when sites try to install add-ons (FF)

    • Check using a downloaded list of suspected sites
    • Check by asking Google about each site I visit
  • Phishing Protection (FF brainstorm)
    • Make it easier to report phishing sites
    • Implement phishing filter that learns automatically; integrate w/ PhishTank

  • International domain name anti-spoofing - notifies user when visually similar characters in the URL are not expressed in the same language (IE)
  • openID - decentralized single sign-on system that is possibly vulnerable to phishing attacks
  • Surf by IP protection (FF brainstorm)
    • Disallow visiting sites by IP address (IP anywhere in URL)
    • Allow local LAN IPs
  • iTrustPage - anti-phishing tool that prevents users from filling out suspicious web forms, and suggests corresponding legitimate form (FF extension)

    • generates unlimited number of encrypted, unique passwords and disposable email addresses
  • Browser handles password generation; single password (FF extension - Magic Password Generator, IE extension - Password Scrambler)
    • Uniquely scrambles your single password for every site you visit

Warning Messages

  • Secure Defaults/No Security Pop-ups - remove security pop-ups because users are trained to click on the default button to complete their task. Use secure defaults instead, and only provide notifications at the top of the browser (FF brainstorm)
  • Fix my settings - instantly reset internet security settings to "medium-high" default by clicking option in Information Bar. The browser warns user with Information Bar when current security settings may put you at risk. The bar continues to remind you as long as settings remain unsafe. Internet Control Panel highlights critical items in red when they are unsafely configured. (IE7)

Encryption (Protocols and Certificates)

  • Word of mouth security
    • Social networks - 7 of your Facebook friends have purchased from this site
    • Personal sources - Your computer-savvy cousin says this site is safe
    • Online ratings - This site has 25 unresolved complaints according to BBB, and a reseller rating of 6.2
  • Security history
    • You've been to this site before
    • Nothing has changed since the last time you were at this site
    • You're sending a password to a site that you've never visited
  • Page Security Scoring - use standard formula to calculate a score to provide consistent and trustworthy security context semantic to users
  • Browser Lock Down - remove security decisions from the user as much as possible; determine behavior based on configuration
  • Personally Identifiable Information Bar
  • Secure Remote Password Protocol
  • Watch for credit card numbers going out on the wire

Pain Points

  • Users ignore security indicators and click through warning dialogs (analogy is "whack-a-mole"); focus is on completing tasks
    • Security indicators are out of the way and hard to interpret; terminology is confusing
      • Security UI needs to be clear and simple
      • In certain situations, it may help if the browser makes a decision for the user while still offering the user another option
      • Security UI must balance obviousness with unintrusiveness, convey clarity in reasonable size, and reflect complexity with simplicity - talk to Jonathan Nightingale
