New Security Policy Added to Demo Site

by

Tonight I added a new CSP – Content Security Policy to the demo.CiteIt.net website.

What are CSPs?

The basic idea behind CSPs (Content Security Policies) is that security can be improved if the webserver is configured to tell visitors’ web browsers to only accept files from approved sources. The policy can also specify specific types of actions that can take place, such as whether popups are allowed and whether the site can be accessed over unsecured HTTP (rather than HTTPS).

One of the benefits of applying a CSP to a website is that a public user adding a new sample post would be prevented from embedding a malicious script from a remote source. Or more accurately, web visitors who view a page with an embedded malicious script would be instructed by the webserver not to load this remote script, even if it were successfully injected into the page.

Allowed:

<script src="https://demo.citeit.net/my/script.js" />

Forbidden:

<script src="https://evil.attacker.com/bad/script.js" />

Because my CSP defines a set of rules that only allows scripts from self, the web server will instruct the browser not to load the malicious remote script.

Apache .htaccess Configuration

These instructions are set by configuring the web server, which in my case is Apache.

Here’s some basic .htaccess code for Apache:


<IfModule mod_headers.c>
    Header Content-Security-Policy-Report-Only: 
        default-src 'self';
        script-src 'self' ajax.googleapis.com; 
        style-src 'self'; 
        img-src 'self'; 
        font-src fonts.googleapis.com, fonts.gstatic.com; 
        connect-src 'self'; media-src www.youtube.com; 
        object-src 'none'; 
        prefetch-src read.citeit.net, fonts.googleapis.com, fonts.gstatic.com; 
        child-src 'self' www.youtube.com; 
        frame-src 'self' www.youtube.com; worker-src 'none'; 
        frame-ancestors 'self'; 
        form-action 'self'; 
        upgrade-insecure-requests; 
        block-all-mixed-content; 
        sandbox allow-forms allow-same-origin allow-scripts allow-popups; 
        reflected-xss block; base-uri 'self'; 
        manifest-src 'none'; 
        report-uri https://demociteitnet.report-uri.com/r/d/csp/enforce

    Header set X-Content-Type-Options nosniff
    Header set X-Frame-Options DENY

</IfModule>

Tightening up Permissions Further:

It is possible to tighten up security further by having the javascript only run a script whose content matches a hash. You see this often with CDNs:

<script src="https://code.jquery.com/jquery-2.1.4.min.js"
integrity="sha384-R4/ztc4ZlRqWjqIuvf6RX5yb/v90qNGx6fS48N0tRxiGkqveZETq72KgDVJCp2TC"
crossorigin="anonymous"></script>

This technique allows the website author to include a remote script from a CDN without worrying that the contents of the script (in this case jQuery) will change. Adding the integrity check prevents the visitor from loading a malicious copy of the script, should the jQuery website get hacked.

Cherry-Picked Quotations on the Jefferson Memorial

Jefferson Memorial: Panel Three (Northeast Portico)

6 Separate Quotations: Northeast Portico

Although it looks as though the text etched into Panel Three of the Jefferson Memorial is a single quotation from Jefferson, it actually is a compilation of 6 separate quotations.  Can you see what was lost when the context of each excerpt was stripped away?

Notice the text two-thirds of the way down: “

Nothing is more certainly written in the book of fate than that these people are to be free.

Individual Quotes:

These Individual Quotes are broken out on the official Monticello website into 6 separate quotations, although quotation #4 about the slaves’ freedom stops short of mentioning their deportation:

      1. “.. But let them [members of the parliament of Great Britain] not think to exclude us from going to other markets, to dispose of those commodities which they cannot use, nor to supply those wants which they cannot supply. Still less let it be proposed that our properties within our own territories shall be taxed or regulated by any power on earth but our own. The god who gave us life gave us liberty at the same time: the hand of force may destroy, but cannot disjoin them.” – “A Summary View of the Rights of British America“
      2. “.. For in a warm climate, no man will labour for himself who can make another labour for him. This is so true, that of the proprietors of slaves a very small proportion indeed are ever seen to labor. And can the liberties of a nation be thought secure when we have removed their only firm basis, a conviction in the minds of the people that these liberties are the gift of God? That they are not to be violated but with his wrath? Indeed I tremble for my country when I reflect that God is just: that his justice cannot sleep for ever . . . .” – Notes on the State of Virginia, Query XVIII1
      3. .. “The whole commerce between master and slave is a perpetual exercise of the most boisterous passions, the most unremitting despotism on the one part, and degrading submissions on the other. Our children see this, and learn to imitate it. . . .” – Notes on the State of Virginia, Query XVIII2
      4. .. The principles of the amendment however were agreed on, that is to say, the freedom of all born after a certain day, and deportation at a proper age. But it was found that the public mind would not yet bear the proposition, nor will it bear it even at this day. Yet the day is not distant when it must bear and adopt it, or worse will follow. “Nothing is more certainly written in the book of fate than that these people are to be free. Nor is it less certain that the two races, equally free, cannot live in the same government. Nature, habit, opinion has drawn indelible lines of distinction between them. It is still in our power to direct the process of emancipation and deportation peaceably and in such slow degree as that the evil will wear off insensibly, and their place be pari passu filled up by free white laborers. If on the contrary it is left to force itself on, human nature must shudder at the prospect held up. We should in vain look for an example in the Spanish deportation or deletion of the Moors.” – Jefferson’s Autobiography
      5. .. “Preach, my dear sir, a crusade against ignorance; establish & improve the law for educating the common people.” – Jefferson to George Wythe, August 13, 1786
      6. .. “It is an axiom in my mind that our liberty can never be safe but in the hands of the people themselves, and that too of the people with a certain degree of instruction. This it is the business of the state to effect, and on a general plan.” – Jefferson to George Washington, January 4, 1786

In Defense of Jefferson:

Some people argue that Historians should throw Jefferson out of the American pantheon for his views on race.  Benjamin Schwarz argues in a March 1997 article in The Atlantic that this would be a mistake:

  1. Even the worst parts of the past are connected to others, and
  2. It “would deprive the United States of the figure central to what is singular and most admirable about the promise of American life — a promise that is already largely forgotten.

Southeast Portico: Open to “progress of the human mind” and “enlightenment”

Jefferson was a complex man.  What he takes away with one hand, he gives with another.

On the opposite wall from the Northeast Portico, the Southeast Portico provides another quote from Jefferson — an edited version of a letter to Samuel Kercheval (June 12, 1816) — that indicates that Jefferson was open to changing his mind and the law.  Here is the original, without the editing:

Source: Letter to Samuel Kercheval

Thomas Jefferson | July 12, 1816

 

I am certainly not an advocate for frequent and untried changes in laws and constitutions. I think moderate imperfections had better be borne with; because, when once known, we accommodate ourselves to them, and find practical means of correcting their ill effects. But I know also, that laws and institutions must go hand in hand with the progress of the human mind. As that becomes more developed, more enlightened, as new discoveries are made, new truths disclosed, and manners and opinions change with the change of circumstances, institutions must advance also, and keep pace with the times. We might as well require a man to wear still the coat which fitted him when a boy, as civilized society to remain ever under the regimen of their barbarous ancestors.

In the Jefferson Memorial, the southeast panel advocating laws and institutions change with “progress of the human mind” appears opposite the northeast panel with the cherry-picked quote about deportation. View the full-sized panoramic photo of the Memorial to inspect the inscriptions and see both panels side by side.

Dear Medium, You Could Combat Fake News by Showing More Quote Context

by


Inspiration:

Some Americans have become so disillusioned with the mainstream press that they refuse to trust basic reporting,  assuming that even direct quotations may have been taken out of context.

Cherry-picked quotations are an old problem, but one which digital tools are uniquely suited to combat.  In this article I’m going to demonstrate how a new set of authoring tools I’ve developed can allow authors to establish greater credibility, by providing readers the additional context they need to quickly evaluate a quotation’s context.

Take for example, the following cherry-picked quotation about slavery from Thomas Jefferson’s autobiography:

Nothing is more certainly written in the book of fate than that these people are to be free.

"Jefferson

The Jefferson Memorial

In this selective quotation, Jefferson appears to be a foreword-looking man, anticipating the emancipation of African-Americans. But if you click on the above down arrow, you can see that the text expands to reveal subsequent sentences which describe Jefferson’s desire to deport all the freed slaves, a part of history which is often omitted from our founding  myths. 1

Quotations that appear in print are frequently devoid of context, requiring the reader to trust the author or follow a footnote.  I call these “severed quotations” because the context necessary for readers to evaluate them has been chopped off.  I use the term “severed” as a way to suggest that we need to establish a new norm for quotations — a norm which the digital medium has only now made possible, where the text surrounding a quotation can be expanded to provide readers with a fuller context.  This new norm can help readers distinguish between those authors who desire to live to a higher standard of accountability, from those who play fast and lose with the record.

Out of Context Quotations in the Media

Take for example, the  Saturday Night Live Sketch that Parodied Sarah Palin:

I can see Russia from my house!

This line was actually a exaggerated paraphrase from Sarah Palin that makes more sense if you read the original ABC News interview’s full transcript.

ABC New’s Actual Interview:

The interview was conducted in Alaska; and early in the interview ABC anchor Charles Gibson raised the topic of Russia’s proximity to Alaska:

GIBSON: Let’s start, because we are near Russia, let’s start with Russia and Georgia.

Later in the exchange, Alaska’s proximity comes up again, with Palin answering Gibson, by saying:

PALIN: They’re our next door neighbors and you can actually see Russia from land here in Alaska, from an island in Alaska.

I was not a Palin supporter, but I am sympathetic to conservatives who say that, whatever faults Palin may have had, ABC News and Saturday Night Live treated her unfairly by taking an otherwise innocuous statement out of context.  It is an accumulation of many of these sorts of incidents that degrades conservatives’ trust in mainstream media sources like ABC News.2

If media outlets want to distinguish themselves from the competition, one visible way of doing this would be to adopt the sort of expanding quotations I’ve demonstrated and coupling this with a campaign to regain public trust.

I created the open-source Neotext project as a way to demonstrate the technical feasibility of this form of expanding quotations, and as a project to develop working implementations on many platforms.

You can experience what it is like to create your own Neotext quotations on my demo site by clicking on the “Test Drive” button below.

Test Drive: WordPress Plugin  (alpha)

 

Popularizing Neotext

The goal of the Neotext project is to provide authors with tools that allow their readers to make an informed evaluation of sources, and to inspire greater confidence in the works of authors who are willing to hold themselves to a higher standard of accountability.

How Medium could adopt Neotext

Medium could be the first platform to adopt this digital writing feature, if it:

  1. added a source URL field to their blockquotes and
  2. incorporated a citation web service, like the one I developed.

How to Help This Project:

If you don’t work at Medium.com and want to help on the WordPress plugin, I’m looking for:

  • Programming collaborators to help me improve the code, and
  • WordPress authors who are interested in being alpha-testers of my plugin.

If you’re interested in staying up to date with the latest news, join my email newsletter or subscribe to the RSS feed.

How the Code Works:

The plugin I created takes advantage of standard html’s blockquote cite attribute, where the url is specified with the “cite” attribute.  Platforms like Medium would need to modify their editors to allow the author to specify a URL with their blockquotes:

  1. When the article is published, the Web Authoring Tool (either WordPress or Medium) scans published articles and checks to see if the article contains a <blockquote cite= “url”> tag.  If the article does, it uses the HTTP POST command to programmatically send the article’s url to the Python web service I created.
  2. The Python Web Service gets the submitted url, downloads the specified article, and for every cited blockquote url it finds:
    • it retrieves the cited document,
    • creates a text-version of the cited source, and
    • locates the quotation starting position.
  3. After the web service locates the quotation, it copies the 500 characters of text before and after the quotation.
  4. The web service saves the 500-character contextual text snippets to a json file on Amazon S3, constructing an identifier from a hash of the quoted text and the page’s url.
  5. When a reader views the citation on the published page, their browser:
    • uses jquery to find any <blockquote> tags with the “cite” attribute,
    • uses javascript to compute the quote’s hash identifier (from citing_url, citing_quote, and cited_url),
    • looks up the json file in the Amazon cloud, and
    • injects the json content into hidden <divs> on the citing page and displays arrows above and below each <blockquote>

  1. This Jefferson quotation can be found in multiple sources, including the Jefferson Memorial, but if we draw in the full context of the quote from page 68 of Jefferson’s 1821 autobiography, we find that additional context reveals a more complicated history.↩

  2. Distrust is also caused by conservative outlets continual promotions portraying the competition as unfair and biased.↩

Article: How Neotext could prevent some types of Fake News

by


Last month I posted an article I wrote about how Fake News, in the form of Out-of-Context Quotations, is not a new issue, but the internet poses both challanges and opportunities.

I described 2 examples of how media sources in 1999 and 2008 took quotations by Al Gore and Sarah Palin out of context and how this could be prevented if media outlets used Neotext.

I also expanded the concept of quote context to video and laid out 3 challenges to technologists.
