Bio Risk
A combination of the probability of occurrence of harm and the severity of that harm where the source of harm is a biological agent or toxin (Source: CWA 15793) is termed a biorisk. The source of harm may be an unintentional exposure (Like what happened to Hulk in the Marvel Universe XD), accidental release or loss, theft, misuse, diversion, unauthorized access or intentional unauthorized release. Bio Risks include both biosafety and biosecurity risks.
How it works
...
Bio Safety
The use of Genetically modified organisms or GMOs is widely accepted and has revolutionised our approach to real world problems. The objective of synthetic biology work is to create massive results with GMOs, without compromising the safety or security of any of the stakeholders involved in the process. But a major aspect of work with GMOs is Biosafety.
What is Biosafety?
Biosafety as defined by the International Convention held in Geneva, refers to “principles, technologies, practices, and measures implemented to prevent the accidental release of, or unintentional exposure to pathogenic agents”.
Hence, as iGEM’ers and synthetic biologists, the onus is on us to ensure that our modified bacteria are not only useful but also well contained, safe and have a benign impact on the user in any detrimental manner.
Biocontainment strategies involving risk based approaches by analysing the pathogen type allow us to contain the pathogen we are working with, thus protecting the workers and preventing unintended release of the pathogens from the labs ( Warning :DO NOT ever fool around labs, you never know what you can do !). Depending on the risk type, pathogen type and various other factors, the required safety protocols and regulations are put in place to prevent unintentional release or exposure to the pathogen being worked with.
Bio Security
( Did you think only cybersecurity exists ? :))
Biosecurity risks are a type of biorisk based on malicious intent. These risks are primarily focused on theft of a biological agent(s), equipment, or information, and sometimes include misuse, diversion, sabotage (not saBOTage XD !), unauthorized access, or intentional unauthorized release. The overall biosecurity risk varies with the intent of the adversary (or threat) aiming to do the malicious act.
Bio Security Risk Assessment
....
Safe by design
THE BIG PIE is focused more on the therapeutics and healthcare track. This made it imperative for us to design a drug that has lab made bacteria but is absolutely safe and effective for the patient. So we created a Safe By Design System to ensure safety for all the concerns we had in mind.
Interaction With Body Environment
Pathogenicity: Our interaction with the public showed us that the general opinion about bacteria was that it is bad for us or “pathogenic”. Keeping this in mind we decided to use Ecoli Nissle which is Gram Negative and is a widely known probiotic. With its applications in treating other intestinal ailments and the protection it provides to the gut. E.coli Nissle would be seen as friendly and safe probiotic instead of a “pathogen”. (Your next door friendly neighbor !)


This package enables users to access MongoDB by running queries and returning their results in R data frames. Usually, data in MongoDB is only available in the form of a JSON document. jSonarR uses data processing and conversion capabilities in the jSonar Analytics Platform and the JSON Studio Gateway (http://www.jsonstudio.com), to convert it to a tabular format which is easy to use with existing R packages.

What is MVC?
MVC is broken into three parts:
-
Model
Models represent the data for your application. They don't know anything about views or controllers
-
View
Views are presented to users and are how users interact with the app.
-
Controller
Controllers are the decision-makers. They are the glue between the model and the view.
An Analogy
Apple Store
Why MVC?
There are multiple advantages to MVC:
-
Separation of Concerns
-
Simultaneous development
-
High Cohesion
-
Low Coupling
-
Ease of Modification
-
Code Organization
Why not MVC?
There are some drawbacks to MVC:
May not be suitable at scale
Limiting for apps with lots of state changes
MVC Frameworks
Examples: Putting convention over configuration
Conclusion
MVC was originally intended to help an end user manipulate an underlying computer system in a more intuitive way.

Instance Attribute Details
#assign_ipv_6_address_on_creation ⇒ Types::AttributeBooleanValue (rw)
Specify true
to indicate that network interfaces created in the
specified subnet should be assigned an IPv6 address. This includes a
network interface that's created when launching an instance into
the subnet (the instance therefore receives an IPv6 address).
If you enable the IPv6 addressing feature for your subnet, your
network interface or instance only receives an IPv6 address if it's
created using version 2016-11-15
or later of the Amazon EC2 API.

And even if you have no plan on using Ecto (Maybe your app doesn't persist data or you're using some other data store) it's still a very interesting solution to the problem that I think is worth studying. --- template: inverse # 2.0 ??? Just FYI, I'll be referring to Ecto 2.0, which is currently in release candidate. There are some API changes and new feature in 2.0. --- .left-column[ # Agenda ] .right-column[ 1. Ecto.Repo 2. Ecto.Migration 3. Ecto.Schema 4. Ecto.Changeset 5. Ecto.Query ] ??? These are the basic building blocks of Ecto and what we'll do is cover them one-at-a-time using a basic blog application for the examples. We'll try to breeze through the first 3 and then the last 2 are really the most interesting pieces of ecto. --- template: inverse # Ecto.Repo --- # Ecto.Repo * Wraps a single database * All actions (insert, select, update, etc) go through the Repo * Decoupled from schemas, queries, and changesets. * Sends actions to database via adapters * Official: PostgreSQL, MySQL * 3rd Party: SQLite, SQL Server, MongoDB * Not actually Repository Pattern --- .left-column[ ## Setup the Repo ] .right-column[ ```elixir defmodule MyBlog.Repo do use Ecto.Repo, otp_app: :blog_app end # ... config :my_app, Repo, adapter: Ecto.Adapters.Postgres, database: "my_blog_db", username: "...", password: "...", hostname: "localhost", # ... MyBlog.Repo.all(query) MyBlog.Repo.get(5) MyBlog.Repo.insert(changeset) MyBlog.Repo.update(changeset) MyBlog.Repo.delete_all ``` ] ??? So you configure your repo. I actually like to call this "DB" sometimes because it seems clearer to me, but we'll keep it as Repo since that's the convention. And as you can see, we're setting it up with Postgres And then at the bottom, you can see how we'll be using the Repo. We'll get more into that in a few minutes. --- template: inverse # Ecto.Migration --- # Ecto.Migration - Highly inspired by Rails migrations - Strongly encourages database integrity - Foreign keys, indexes, etc ??? very different than the Rails world. This has changed a bit lately, but Rails seemed to have the attitude of treating your database as a dumb data store. Ecto definitely goes in the other direction on this. --- ## Example Migration ```elixir defmodule MyBlog.Repo.Migrations.CreatePost do use Ecto.Migration def change do create table(:posts) do add :title, :string, size: 100, null: false add :slug, :string, size: 100, null: false add :content, :text, null: false timestamps end create unique_index(:posts, [:slug]) end end defmodule MyBlog.Repo.Migrations.CreateComment do use Ecto.Migration def change do create table(:comments) do add :post_id, references(:posts, on_delete: :delete_all), null: false # ... add :content, :text, null: false add :votes, :integer, null: false, default: 0 timestamps end create index(:comments, [:post_id]) end end ``` ??? Here are a couple example migrations. It's fairly straight forward but just a few things to note: * It adds primary key fields by default * And it's easy to add created_at and updated_at timestamps. * That references function creates foreign keys for you. --- template: inverse # Ecto.Schema --- # Ecto.Schema .red[*] ### Tell Ecto about the structure of your DB and how it maps to Elixir structs - Define fields - Define associations - belongs_to - has_many - has_one - many_to_many .footnote[ .red[*] called Ecto.Model in 1.0 ] --- .left-column[ ## Example Schemas ] .right-column[ ```elixir defmodule MyBlog.Post do use Ecto.Schema schema "posts" do field :title, :string field :slug, :string field :content, :string field :active, :boolean has_many :comments, MyBlog.Comment timestamps end end defmodule MyBlog.Comment do use Ecto.Schema schema "comments" do belongs_to :post, MyBlog.Post field :content, :string field :votes, :integer timestamps end end ``` ] ??? Here are a couple example schemas for the two tables we created in the migrations. Look very similar to the migrations. Note that we define which other schema our associations map to. --- template: inverse # Ecto.Changeset ??? Ok, now that we've defined our Repo, created our tables, and setup our schemas, we're read to insert data into the database. --- # Ecto.Changeset - Cast and filter external parameters - Perform validations - Track changes - All done by transforming a Changeset struct, then passing it to the Repo ??? --- # Simple Changeset Example ```elixir defmodule MyBlog.Post do # ... def changeset(post, params) do post |> cast(params, [:title, :content, :active]) |> validate_required([:title, :content, :slug]) |> validate_format(:slug, ~r/^[a-z0-9-]+$/) |> validate_length(:title, max: 100) |> unique_constraint(:slug) end end ``` ```elixir post_changeset = Post.changeset(%Post{}, %{title: "Hello World", ...}) # Returns something like: # #Ecto.Changeset
, valid?: true> Repo.insert(post_changeset) ``` ??? So here we have a very basic example of a changeset. It accepts a post struct and a hash of parameters. If we were doing an update instead of an insert, that struct would something we retreived from the database and would be populated with data. cast: whitelist a set of parameters that we're going to accept Notice the unique_constraint function. Ecto validations are integrated with database constraints so that when we do have an issue, we can present the user with a nice validation error. And what we return is a Changeset struct that has all of the information we need. * The changes made * The validation results * The original data * etc --- # Composable Changesets ```elixir defmodule MyBlog.User do # ... def changeset(user, params) do user |> cast(params, [:username]) |> validate_required([:username]) end def registration_changeset(user, params) do user |> changeset(params) |> cast(params, [:password, :password_confirmation]) |> validate_confirmation(:password) |> generate_password_hash() end defp generate_password_hash(cs) put_change(cs, :password_hash, SomeLibrary.encrypt(cs.changes.password)) end end ``` ??? Now let's look at a more complex scenario. Say we have two different pages that update users: * A registration page * An admin page to update existing useres In one scenario, we want to validate the password and encrypt it. And in the other maybe we don't care. So we just create two changesets, and the registration one just calls the basic one. --- template: inverse # Ecto.Query --- .left-column[ # Ecto.Query ] .right-column[ - Syntax inspired by LINQ - Language INtegrated Query - Introduced into .NET in 2007 - Required syntax additions to C#, F#, and VB.net ```elixir from p in Post, where: p.active == true, select: p ``` - Added to Elixir via Macros - Queries are passed to the Repo for execution - The Repo returns structs shaped like the schema you defined ] ??? During the dark times when I was a .Net developer, I remember when LINQ came out and thinking it was pretty cool. Now let's look at some ecto query examples --- ## Example 1: Select All Posts ```elixir alias MyBlog.{Repo,Post,Comment} Repo.all( from p in Post, select: p ) ``` --- ## Example 2: Select All **Active** Posts ```elixir Repo.all( from p in Post, where: p.active == true, select: p ) ``` --- ## Example 3: Preload an association ```elixir Repo.all( from p in Post, preload: [:comments] where: p.active == true, select: p ) ``` --- ## A Note on Preloading You have to **explicitly** load associations. ```elixir # Without Preloading: %MyBlog.Post{__meta__: #Ecto.Schema.Metadata<:loaded>, comments: #Ecto.Association.NotLoaded
, content: "hello world", id: 1, inserted_at: #Ecto.DateTime<2016-04-19 16:49:24>, title: "My First Post", updated_at: #Ecto.DateTime<2016-05-19 16:49:24>}} ``` ??? So if you don't preload association, then you try to iterate over it, it's not going to magically pull it down for you and you're going to run into an error. Which is a good thing because you're much less likely to run into n+1 issues. --- ## Example 4: Preload association using a Subquery ```elixir comments_query = from c in Comment, order_by: c.votes, limit: 3 Repo.all( from p in Post, preload: [comments: ^comments_query] where: p.active == true, select: p ) ``` --- ## Example 5: Pagination ```elixir comments_query = from c in Comment, order_by: c.votes, limit: 3 offset = 50 per_page = 25 Repo.all( from p in Post, preload: [comments: ^comments_query] where: p.active == true, offset: ^offset, limit: ^per_page select: p ) ``` ??? Ok, this is starting to get complicated. How can we break this up and make it more reusable. Like anything elixir, you can just break into a series of functions. --- ## Example 6: Composing Queries ```elixir def is_active(query) do from q in query, where q.active == true end def preload_popular_comments(query) do comments_query = from c in Comment, order_by: c.votes, limit: 3 from q in query, preload: [comments: ^comments_query] end def paginate(query, page, per_page) do offset = (page - 1) * per_page from q in query, offset: ^offset, limit: ^per_page end ``` ```elixir Repo.all(Post) |> is_active |> preload_popular_comments |> paginate(3, 25) ``` --- # Alternate, Pipe Based Querying Syntax ```elixir Post |> preload([:comments]) |> where([p], p.active == true) |> select([p], p) |> Repo.first Post |> join(:inner, [p], c in assoc(p, :comments)) |> where([p, _], p.active == true) |> select([p, _], p) |> Repo.all ``` --- template: inverse # Questions? .centerbottom[ @adam_albrecht ]


Oaxaca, Mexico
Post Mortem Chapel
The ruins of an abandoned church mingle with the graves at Oaxaca’s General Cemetery.
by Mario Yair TSHidden within Oaxaca’s General Cemetery are the remains of the Post Mortem Chapel. The structure was commissioned in 1835, but because of ongoing political conflicts, it was never finished.
There were attempts to complete the sanctuary’s construction, but the municipality finally gave up after the French Intervention of 1865. That year, the building’s plans and the model of the project were lost. Today, it remains an unfinished ruin, and no one is sure what it was meant to look like.
The church’s main arch was nearly destroyed by a 2017 earthquake. Although the abandoned building’s walls are enormous, they remain obscured by trees and graves. There’s an empty tomb in the center of the ruins, guarded by a cross and accompanied by an inscription that reads “a flower for the forgotten dead.” People leave flowers and light candles at the tomb in honor of the cemetery’s dead who no longer receive visitors.
Know Before You Go
A few steps from the chapel is the empty niche where Macedonio Alcalá was once buried. On his deathbed, he composed the waltz "God Never Dies," one of the most popular songs of the Day of the Dead in Mexico. Today, his remains are lost forever, just like the chapel project.
The cemetery opens at 7 a.m. The best time to visit the cemetery is the night of the Day of the Dead, when the cemetery and niches are only lit with candles and flowers.

Unfortunately we (family) have all been under the weather with different grades of sickness. My wife, and now me have a pretty nasty stomach bug which also seems to attack the throat. The kids are all much better but are generally very tired.
Not nice.
All of this is to say that my new-found blog isn't getting off to the best start.

Nuxeo Platform 7.3 Release Notes
For Users
Live Connect for Google Drive / Dropbox
Live Connect allows you to create a content application that handles cloud files (Dropbox, Google Drive, in the future One Drive, Box...) as if they were local files. Files remain in the cloud but they are referenced in the Nuxeo repository as if they were stored within it. This allows the user to benefit from thumbnailing service, full text, conversions, etc. Live Connect for Google Drive also brings the "Cloud Edit" mode. Your application based on the Nuxeo Platform can provide the users with a direct link to the SaaS applications that you can use for editing Google Drive files (Google Docs, Office 365, Pixlr, etc.).
PDF Viewer
A PDF viewer has been integrated, based on the pdf.js lib. It provides the ability to zoom, rotate, and access a specific page, as well as support the streaming of the PDF when the file is large, starting the display of the first pages as soon as they are downloaded. The preview chain for office documents now goes through PDF formatting in order to use this viewer for viewing any Office file. This PDF viewer is made available via a simple URL that accepts the URL of the file to preview as a parameter.
File Dispatching
An abstract base class of BLOB Manager is made available for implementing a storage policy and decide that some BLOBs are stored on S3 or locally, or on different on premise storage systems. The policy can take into account:
- The metadata of the document (example: if a "confidential" flag is set to true, then store the BLOB on premise, otherwise store on S3)
- The lifecycle state of the document
- The characteristics of the binary (example: store video files on S3, and store other files on premise) This allows you to implement the right storage policy for your business rules, including setting hierarchical file system (HFS) policies.
Media Content Publishing
A new plugin has been added that allows for publishing content on the cloud. This plugin can provide multiple target implementations. Currently, implementations for YouTube and Wistia are provided. User can publish a video either to the YouTube or Wistia site, get a link to the published asset and also get the HTML snippet for embedding it. User can also view from Nuxeo Platform the statistics of the videos, such as the number of views. This is great for using Nuxeo Platform as a DAM repository and then easily push your content online. One could also add implementations for other online publishing sites, such as Slideshare, Vimeo, and many more. Please do not hesitate to contribute!
Cloud Services management screen in Home and Admin Center
Users are able to manage their oAuth tokens via the Cloud Services section from where they can connect to different Cloud Services, such as Dropbox, GooglePlus and Google Drive. It is also possible to share a token with other groups of users. This can be useful, for example, with Media Content Publishing, if you want to share a YouTube or Wistia account with multiple users in your department.
Web Authentication for Drive
A web window is now used the first time a user authenticates with Nuxeo Drive against a Nuxeo Platform server. This allows to use the same authentication protocols than the one configured on the Nuxeo Platform Web UI, such as an SSO system, SAML, Shibboleth, etc..
Logging of File Download
All file downloads now take place in the same component that tracks the downloads and logs them in the audit trail. This is the beginning of a series of improvements we have planned pertaining to downloads.
Saved Search
Saved searches sort criteria is now saved. In next release, it will also be possible to edit it.
Full path is visible on the the root selector of publishing tab.
On the publishing tab, users can set publishing target preferences. Previously, only the name of the selected folder was displayed. The path is now also displayed, to ensure the target folder is the correct one as intended by the user, and not a different folder elsewhere that has the same folder name.
Allows you to set lifecycle state when using csv import.
In the CSV importer, it is now possible to define the lifecycle state the imported document should have.
Video Player can be used with any property.
You can use the native video player with any binary property your configured with Nuxeo Studio on your content type.
For Developers
Automation
Class Filter on Automation Scripting
It is no longer possible to perform Java imports from an Automation Script, as a class filter has been added to the Nashorn VM. This has been done for security and maintenance reasons.
Platform functions available in Automation Scripts
You can use Platform Functions under the Fn object like in Automation chains in Automation script, as it has been added to Nashorn context.
Helpers Automation
An extension point has been implemented to configure new function helpers to the automation module:
HTTP Helper
A new helper for HTTP calls as been added. It can be used to perform external services API calls right from an automation script. See exemples for our documentation.
Elasticsearch
Elasticsearch API passthrough
A proxy api has been implemented on the Nuxeo Platform so you can use native Elasticsearch GET queries as documented on the Elasticsearch documentation website. The proxy will ensure that only those documents each end user has the right to view are returned in search query results. Thanks to this feature, Elasticsearch-skilled developers can add the Nuxeo Platform in their architecture and benefit from a secure and modular content store with an extensible content management user interface, while still implementing their front office with JavaScript ES sdk.
Elasticsearch Hints
Elasticsearch hints have been added to NXQL and to the page provider object. It allows you to use native Elasticsearch operators in your query when using an Elasticsearch page provider. This will help you build content applications with fuzzy search support, phrase search, using specific tokenizers (arabic, chinese, phonems), as well as run geographical queries against the repository, such as searching for all photos that where taken within a scope of 5 miles around the Brooklyn bridge. It also allows you to hit specific index fields. Nuxeo Studio Content View feature has been updated to support the declaration of Elasticsearch hints (operator, analyzer and field).
API Evolutions
File Support on workflow API
You can now upload a file for completing a task using Workflow REST API
Reassign and Delegate task endpoint
Workflow Rest API provides ways to reassign or delegate a given task.
Get Rendition operation
This new operation allows you to fetch a given rendition on a document in input.
Conversion
A web adapter has been added on Rest API: /@blob/file:content/@convert?format=pdf for getting a conversion of a binary property, given a converter or a target mime type (as parameters).
Workmanager find method
A Java method has been added on workmanager service for performing an optimized search of a given job.
JSON export of layout and widgets
This new API end point allows you to get the layout and widgets instances serialization in JSON for helping you build specific front office UIs, while leveraging the forms and data display you have declared in Nuxeo Studio.
UI
Pluggable file widget
View mode of file widget is pluggable: you can contribute actions to display new links besides the file download link.
JavaScript list widget
A second implementation of the generic List widget is provided in Javascript that fixes many bugs encountered on the initial implementation. This is the one used by default on Fast Track and it has been back ported as an option in 6.0.
REST endpoint for CSS and JS resources
A new endpoint is available for serving CSS and REST resources on a web pages of Nuxeo Platform Web UI. This is a first step of the refactoring that will lead to the removal of the use of the legacy Theme framework.
oAuth Service Providers extension point
It is possible to plug new oAuth Service providers with custom logic on parts where the protocol is not precise enough.
Web Components and Polymer
We have started to add Polymer dependencies to the build. You will notice a new tab for managing rights on a document now appears, but it is disabled by default, as this is still a work in progress using Polymer.
Removal / Deprecation
- Open social and dependencies have been removed from build.
- CMF and dependencies have been removed from the build.
- Faceted Search is deprecated.
- Placeful service was removed.
For Administrators
Changing Tomcat Admin Host
A new parameter in nuxeo.conf allows you to customize the address for which the server waits for a shutdown command.
VCS Full Text Search Enablement and Configuration
Most of the production set up will now rely on Elasticsearch for full-text search. In that case you can disable the VCS full-text index computation by setting the following flag set to true:
Alternatively, if you do want to use it, it is now easy to configure the analyzer language thanks to the following property:
.Elasticsearch Server Version Recommended is Now Elasticsearch 1.5.2
Reindexing Optimization and Reindexing on Startup
Recursive indexing has been made much quicker thanks to a change in the algorithm. We now propose a flag for automatizing it on startup when the index is empty:
Audit is Stored in Elasticsearch
The default backend for the audit is now Elasticsearch. This improves scalability when using Nuxeo Drive for a large set of users. It also allows you to store more information on each audit entries, such as the complete serialisation of the document. This new capability will be leveraged in upcoming versions of Nuxeo Platform.

Writer Jailed Over Research Is to Be FreedBy THE ASSOCIATED PRESS
The writer, Vanessa Leggett, 33, is to be freed from a federal detention center in Houston because the grand jury that had demanded all her research for a book on a killing has ended its investigation of the victim's husband, said Ms. Leggett's lawyer, Mike DeGeurin. Kesha Handy, a spokeswoman for the United States attorney's office for the Southern District of Texas confirmed that Ms. Leggett would be released on Friday. Ms. Leggett was jailed on contempt charges on July 20 after refusing to hand over her research. Federal prosecutors contend that she is not a journalist and therefore does not fall under the First Amendment's protection of the press. Ms. Leggett has never published a book or news article; her previous writings have appeared in academic journals. In an effort to protect herself from being jailed again over her research, Ms. Leggett will continue her appeal of an appellate court decision that upheld her incarceration, Mr. DeGeurin said. Federal prosecutors have indicated that they will renew their request for Ms. Leggett's material, he said. The Supreme Court has not yet decided whether it will review Ms. Leggett's case. Ms. Leggett attracted attention from federal agents investigating Robert Angleton, a millionaire and former bookmaker whose wife, Doris, was shot to death in 1997. Ms. Leggett had interviewed many people involved in the case, including Mr. Angleton's brother Roger, who was also charged in the killing and committed suicide in jail. (reprinted from NY Times 1/4/02) FBI Wants to Keep Digital Snooping Secret Keystroke-recorder used in mob case is a matter of national security, government says George A. Chidi Jr., IDG News Service Monday, August 27, 2001 Federal prosecutors want to keep their keystroke-tracking methods secret, claiming the PC bugging tactic is protected under Classified Information Protection Act. The issue has risen in the criminal trial of an accused Mafia loan shark, but privacy advocates say the precedent could set standards for PC "wiretapping." U.S. District Court Judge Nicholas H. Politan has granted the government's motion to keep secret--for now--the technical details of a computer keystroke logging tool. The judge will privately review a detailed description of the device, without revealing it to the defense. He will consider the government's claim that national security would be at risk if the method's details become public. If Politan decides the government's national security claim is valid, then the defense--and the public--will see only a limited description of the key logger system's inner workings. FBI agents acting with a warrant surreptitiously broke into the office of Nicodemo S. Scarfo Jr.'s in May 1999 to plant a keystroke logging device on his PC. In an earlier raid on the office, FBI computer experts found one encrypted file they could not break. The keystroke logger enabled agents to record the file's password as Scarfo typed. "There's a lot about the technology used by the FBI that could be publicly discussed, and deserves to be publicly discussed," says James Dempsey, deputy director for the Center for Democracy and Technology, an advocacy group. "This is a hugely important case, because the government says if it can't get what it wants by other means, it will break into your house and plant a device that records everything you type until it gets what it wants." Racketeering Charged The U.S. Department of Justice, working with the FBI, charged Scarfo with racketeering, illegal gambling, and loan sharking as a member of what they call a Mafia crime family. Scarfo's father is jailed mob boss Nicodemo S. "Little Nicky" Scarfo Sr. The warrant specifically required that the key logger device not be used to monitor Scarfo's Internet traffic, because tracking a user's surfing requires a warrant equivalent to one for a wiretap. The defense has argued that it cannot determine if the technology violates the warrant, because the government won't reveal information about the program. Prosecutors contend that if details of the key logger system are made public, it will be useless in further investigations and will jeopardize current ones. Lawyers on the case are under a gag order, and cannot comment to the media about the trial. High-Tech Snooping The Scarfo case raises new issues for privacy, but not all have to do with emerging technology, Dempsey says. "The troubling thing is the lack of notice," he says. "Here, they had a Fourth Amendment warrant ... but they didn't issue notice for the search. In the Scarfo case, and a growing number of cases, the government is claiming it can dispense with the notice requirement and can come into your house secretly, plant things, take pictures, copy things, and leave without telling you. That is a huge attack on the Fourth Amendment." The key logger system illustrates the increasing role of technology in government surveillance, and the increasing gap between the pace of the law and the advance of science. Another prominent electronic-surveillance issue involves Carnivore, now renamed the more public relations-friendly DCS1000 surveillance system. Carnivore allows law enforcement agents to intercept e-mail, ostensibly sifting through public electronic transmissions to get to the target's correspondence. The system raises privacy concerns because it isn't clear if Carnivore prevents agents from capturing e-mail beyond the target of a warrant.

Chidi Jr., IDG News Service Friday, January 04, 2002 A federal judge in New Jersey has rejected a defense motion to suppress computer evidence gained in an FBI case against an accused Mafia loan shark, possibly clearing a path for the government to use secretly installed keystroke logging tools to defeat encryption. FBI agents acting with a warrant in May 1999 installed a keystroke logging device on the computer of Nicodemo S. Scarfo Jr., hoping to record a password for a file encrypted with PGP (Pretty Good Privacy) software. Scarfo's attorneys hoped to suppress the evidence as unconstitutional, a violation of the U.S. Constitution's Fourth Amendment protection against unreasonable search and seizure. The defense also objected to the government's effort to keep the workings of the keystroke logger secret. Federal prosecutors call Scarfo a mobster--Scarfo's father is jailed mob boss Nicodemo S. "Little Nicky" Scarfo Sr. The DOJ charged the younger Scarfo with racketeering, illegal gambling, and loan sharking. Prosecutors invoked the Classified Information Protection Act in August of 2000, asserting that the technical details of the computer keystroke logging tool must remain a secret in the interest of national security, a move more typically associated with protecting military or espionage secrets like those involved in the Wen Ho Lee nuclear secrets case or the spy case of Robert Hanssen, who was an FBI agent. Was Access Limited? The warrant permitting the keystroke logger to be installed specifically prohibited the government from monitoring Scarfo's Internet communication. Scarfo's attorneys claimed that by keeping details of the logger's mechanisms secret, the defense could not determine if the warrant had been breached. "We didn't capture any kind of electronic communications," said Ronald Wigler, an assistant U.S. attorney for the New Jersey district. While the judge received a classified briefing on the workings of the keystroke logger, he concluded based on unclassified parts of the briefing that no communication interception occurred, Wigler said. U.S. District Court Judge Nicholas H. Politan rejected defense arguments in his ruling, indicating that the summary description of the keystroke logger made public in court meets the defendant's need to know what facts or documents the prosecutors are likely to use at trial to make their case. Caution Urged "We must be ever vigilant against the evisceration of Constitutional rights at the hands of modern technology," Politan wrote in the ruling. "Yet, at the same time, it is likewise true that modern-day criminals have also embraced technological advances and used them to further their felonious purposes." Scarfo's attorneys plan to file a motion asking the judge to reconsider. "The government's philosophy is that you shall have no secrets that they cannot reach, and I think that is a chilling philosophy," said Norris Gelman, a Scarfo defense lawyer in Philadelphia. Privacy advocates objected to the nature of the government's intrusion into Scarfo's office--done secretly with no notice to the target until long after. (reprinted from PC World) 'Patriot Act' Opens ISPs to Monitoring Carnivore, other tools start monitoring network activity under new rules George A. Chidi Jr., IDG News Service Monday, November 05, 2001 Under the newly enacted Patriot Act of 2001, ISPs and network administrators may give law enforcement agents access to their networks without a warrant in order to track hacker activities. The legislation is known as the Patriot (Provide Appropriate Tools Required to Intercept and Obstruct Terrorism) Act. It expands the government's ability to monitor communications, including e-mail and cell phone conversations, and share that information among agencies. Its aim is to "provide law enforcement agencies with the appropriate tools to prevent" terrorism like that which occurred on September 11, with the attack on the Pentagon and World Trade Center, according to F. James Sensenbrenner, Jr. (R-Wisconsin), chair of the House Judiciary committee. Now, law enforcement may not compel an ISP to grant access without a warrant. Under previous law designed to protect user privacy, ISPs were specifically forbidden to grant network access without customer permission or a judge's order. Agents can monitor hackers without a warrant, but cannot monitor an ISP's bill-paying customers without one. Even if a customer is engaged in illegal activity, law enforcement must get a pen register--a judge's authorization equivalent to what's needed for reading incoming and outgoing phone numbers--to track the user's Web surfing habits and e-mail addresses, and a wiretap warrant to read e-mail or monitor other communications. Uncaging Carnivore In addition, the U.S. attorney general is required to report semiannually to Congress on its use of the so-called Carnivore e-mail and Internet surveillance system, renamed DCS 1000 The law requires agencies keep a record of who installed e-mail taps, when and for how long, how Carnivore was configured, and what was recorded. Carnivore can be used only after a judge signs a pen register, and the records must be given under seal to a judge 30 days after the court order for e-mail filtering expires. For agents to tap without a warrant, an ISP must own its network, law enforcement must be involved in a lawful investigation, and only the suspect's communications can be intercepted. While the police must have "reasonable grounds to believe that the contents of the computer trespasser's communications will be relevant to the investigation," the law is not specific to hacker terrorists and can be applied to any computer crime investigation. ISPs are not compelled to furnish facilities or technical assistance without being "reasonably compensated." Privacy advocates have reacted strongly to the antiterrorism bills, arguing that civil liberties are at stake. The Electronic Privacy Information Center has urged lawmakers not to limit civil liberties in its attempt to investigate terrorists. EPIC has focused specifically on computer and communication monitoring. (reprinted
