The Information Security class I teach at the University of Wisconsin-Madison, is a broad survey course. To be honest, sometimes the material gets a bit dry. Therefore, tomorrow's lecture, which was supposed to be about secure network architecture, will now instead be about the Deep Web, the scary and mysterious part of the Internet, dedicated to spooky, nefarious and illegal activity. I think it is good to give the students a break from classic course material, and spend some time on this tangentially related topic. I am putting together a class discussion exercise to go along with it.
A spooky presentation about the Deep Web. Deep Web (also called the Deepnet,Invisible Web, or Hidden Web) is World Wide Web content that is not part of the Surface Web, which is indexed by standard search engines. It should not be confused with the dark Internet, the computers that can no longer be reached via the Internet, or with a Darknet distributed filesharing network, which could be classified as a smaller part of the Deep Web. Some prosecutors and government agencies think that the Deep Web is a haven for serious criminality.[4]
Keeping with the Halloween spirit, I created an entire lecture devoted to the spooky deep web, for my Information Systems 365/765 students. In class I often try to tell them to memorize certain concepts and learn about topics which they can pull out in a job interview. If they can talk competently to a recruiter about the technologies used for illicit activities on the deep web, it is something that the interviewer will remember. It also makes lecture a lot less boring, when you can explore a niche topic such as the deep web. I am always available for corporate consulting engagements, if you are interested.

Security Related Issues Associated With Migrating to Cloud ServicesNicholas Davis
This presentation is provides a background on Cloud Services and associated Cloud Security. It is intended to provide an overview of how to maintain the confidentiality, integrity and availability of your company's information systems and assets when choosing to migrate to a cloud based IaaS, PaaS or SaaS model.
This document provides an overview of the surface web, deep web, and dark web. It defines each term and describes their key characteristics. The surface web is the portion of the world wide web that is accessible via traditional search engines. The deep web consists of dynamic or password protected websites that are not accessible via most search engines. The dark web exists on darknets and dark websites that require specific software like Tor to access and allow for anonymous communication. The document outlines the history of these terms and how search engines work to index the surface web. It also discusses applications of the deep and dark webs as well as their advantages and disadvantages.
In my opinion, this is what is wrong with Internet today. Anonymity seemed like a great idea when the Internet was first created, but quickly, this privilege was abused. Many people and groups use the Internet to mislead consumers, lure children into joining terrorist groups, or scam your parents and friends out of money with enticing email campaigns.
The document discusses the surface web and deep web. It defines the surface web as the portion of the world wide web indexed by conventional search engines. The deep web is much larger, containing over 500 times more information than the surface web. This includes dynamically generated websites that search engines cannot access. The deep web is also known as the invisible web or hidden web. It explains how search engines work and index databases, but cannot access information behind search forms in the deep web. It then discusses the Tor network and how it provides anonymity by routing traffic through multiple nodes. Some popular deep web search engines and sites are also mentioned like The Onion Router (Tor) network and darknet markets.
The document discusses the deep web, which contains over 500 times more content than the surface web that is indexed by search engines. It contains approximately 7,500 terabytes of data across 550 billion documents that standard search engines have difficulty accessing directly. The document also outlines methods for searching the deep web through federated search engines and databases that provide access to collections such as government and academic information.

To access the deep web, one must install the Tor browser to reach .onion addresses and access content like instructions on making devices, discussion forums, marketplaces, and information on Bitcoin, which allows anonymous possession and transfer of value.
The document presents a seminar on the deep web and darknet. It defines the deep web as parts of the internet not indexed by standard search engines and requires special search engines or direct URLs to access. The deep web is much larger than the surface web accessible through standard search engines. The darknet refers specifically to parts of the deep web that are intentionally hidden and can only be accessed through anonymity software like TOR. The presentation outlines the history and development of the deep web and darknet, how search engines fail to index deep web contents, how to access and use the darknet anonymously, common items traded on darknet markets, and associated risks and challenges.
The document discusses the deep web and dark web. It defines the deep web as parts of the internet that are not indexed by standard search engines, including private social media content and online banking. The deep web has different levels, with higher levels like the dark web only accessible through anonymous networks like Tor and requiring special software. The dark web is known for illegal activities but also has some legal uses. The document provides instructions for accessing the deep web through downloading Tor browser software to browse anonymously.
The document provides information on the conception of the Internet and web. It discusses that the Internet is a global system of interconnected computer networks that use TCP/IP, while the web is a system of interlinked hypertext documents accessed via the Internet. It also outlines some of the key protocols like HTTP, IP, and TCP involved in enabling communication and functioning of the Internet and web.

This seminar presentation provides an overview of deep web data extraction. It defines the deep web as content that is not indexed by typical search engines. The presentation covers the history of the deep web, how search engines work, differences between the deep web and surface web, how to access the deep web using tools like Tor, advantages and disadvantages of the deep web, and future applications. The presentation concludes that the deep web provides anonymous access to valuable information not easily accessible otherwise and will continue growing as more users seek online privacy and security.
This document provides a summary of a report that mapped the dark web for the first time. The summary is:
The report used complex algorithms to map over 29,000 dark web addresses, of which around 15,000 were accessible. It found that around half of the dark web's content was legal, with the other half containing material likely illegal. The dark web was also found to be much smaller than commonly believed, at around 30,000 sites, compared to over 1 billion internet sites. The report provides insights into dark web categories, languages used, and aims to increase transparency around its contents.

It directs viewers to the website www.superrugbyonline.net to watch the live stream of the match. The Crusaders will host the Lions at their home stadium in Christchurch, New Zealand on this date.
The document discusses the deep web and dark web. It defines the deep web as parts of the world wide web that are not indexed by standard search engines and contains much more data than the surface web. The deep web is used by the military, scientists, journalists and others to securely store and access data anonymously. While it provides advantages like anonymity and access to banned sites, it also enables illegal activities on the dark web like drug sales, hacking, and other crimes if misused. Proper safety precautions are needed when accessing the deep web.

Goal and threat modelling are important activities of security requirements engineering: goals express why a system is needed, while threats motivate the need for security. Unfortunately, existing approaches mostly consider goals and threats separately, and thus neglect the mutual influence between them. In this paper, we address this deficiency by proposing an approach that extends goal modelling with threat modelling and analysis.

Spooky Halloween IT Security Lecture -- The Deep WebNicholas Davis
On the occasion of Halloween, I like to give the students in my IS 365 Information Security class at the University of Wisconsin-Madison, a break from the normal course material. Therefore, today, I presented a class lecture on the Deep Web (the hidden, scary and dark side of the Internet) Appropriate for this spooky time of year. While it was intended to be fun, it also sparked good conversation within the class, and they learned some solid concepts about ways in which people try to evade IT security controls, to preserve anonymity.

The Deep and Dark Web - Spooky Halloween Information Security Lecture -- Info...Nicholas Davis
This presentation provides an overview of the deep web and discusses some of the dangers it poses. It defines the deep web and explains how it differs from the surface web. The presentation notes that the deep web is much larger than the surface web and contains dynamic, unlinked, private, and restricted content that search engines cannot access. It describes how tools like Tor can be used to anonymously access dark web sites ending in .onion and discusses some of the illegal activities that occur on the deep web, like drug trafficking, weapons sales, and hiring criminals. The presentation aims to educate information security professionals about the deep web so they can help address illegal activities occurring there.
Right below the surface of where the iceberg meets underwater is the deep web.
It’s comprised of the same general hostnames as sites on the surface web, but along with the extension of those domains.
This is the specific URL of your Facebook Messenger thread with a friend, or the Department of Justice’s public archival material, or Harvard’s internal communications system. The deep web is the majority of the internet as a whole.
This document provides an introduction to the deep web, including its size, evolution, and how it can be accessed. The deep web refers to content that is not indexed by standard search engines and is much larger than the surface web that search engines can index. It includes dynamically generated pages that can only be accessed through a form and private pages that require login credentials. Sites on the deep web can only be accessed using special browsers and protocols like Tor that allow for anonymous surfing through onion addresses. While some deep web sites provide legal content, others are used for illegal activities and information sharing.
This document summarizes a research paper on integrating search interfaces in deep web databases for specific domains. It begins by defining the deep web and challenges in crawling it due to search forms requiring queries. It then discusses representing a search interface internally and generating meaningful queries. The paper presents an approach using semantic relationships to integrate search interfaces in a domain and generate a unified interface. It utilizes concepts and labels from a task-specific database to select query values for search forms. The goal is to crawl a selective portion of the deep web to extract content for a particular application or task.
The deep web refers to parts of the internet not accessible by standard search engines like Google. It includes dynamically generated pages not indexed by search engines, fee-for-service sites requiring payment to access content, private databases only accessible to authorized users, and the dark web accessible only through specialized browsers like Tor. The deep web gives access to far more information than the surface web and increases privacy through encryption, but it also undermines the openness and equality of the early internet by restricting access to paid services and databases.
A darknet (or dark net) is any overlay network that can be accessed only with specific software, configurations, or authorization, often using non-standard communications protocols and ports. Two typical darknet types are friend-to-friend networks (usually used for file sharing with a peer-to-peer connection)and privacy networks such as Tor.
The deep web refers to content on the world wide web that is not indexed by standard search engines. It contains dynamic content, unlinked pages, private websites that require login credentials, and content in formats like videos or images that search engines cannot access. While the deep web offers anonymity and a place to access information privately, it also enables illegal activities due to its anonymity. The deep web represents a vast amount of information with applications in research, business, and communications for both good and bad purposes.

A large portion of data available on the web is present in the so called deep web..
World Wide Web content that is not part of the Surface Web and is indexed by search engines.
It is called the Deep Web, Invisible Web or Hidden Web.
The document discusses the deep web, which contains a vast amount of information that is not accessible through typical search engines. It estimates the deep web contains over 500 billion documents, compared to only 1 billion on the surface web accessible via search engines. The deep web consists of dynamic content, private databases, and other resources not typically indexed by search engines. The document provides tips on how to search and tools to access information on the deep web, including using specialized search engines and databases for topics such as science, engineering, and other subjects.

Dreamweaver is an application that helps design websites easily with a drag-and-drop interface and automatically generates the underlying HTML and CSS code. It allows users to save files and upload them to a web server without having to manually write code. HTML stands for Hypertext Markup Language and is the primary markup language used to structure content on the World Wide Web. A HTML tag defines elements like hyperlinks that link between pages.
The document traces the evolution of the world wide web from its early beginnings. It discusses how the web started in the 1980s as a way to share scientific information but was plain text-based and boring. The development of graphical web browsers in the early 1990s made the web more visual and popular. This led to explosive growth, with over 25 sites by 1992. Later innovations such as broadband, web applications, user-generated content and social media transformed the web into the interactive medium it is today. The document also briefly mentions potential future directions for the web such as Web 3.0 with new technological capabilities.
This document provides an overview of fundamentals of web development, including definitions, history, and technical concepts. It begins with definitions distinguishing the internet from the world wide web. It then covers the development of digital communication technologies from circuit switching to packet switching and the ARPANET. The document discusses the invention of the world wide web by Tim Berners-Lee and the development of core web technologies. It provides an overview of internet protocols including the TCP/IP model and IP addressing. It also covers client-server and peer-to-peer network models.
Conducting a NIST Cybersecurity Framework (CSF) AssessmentNicholas Davis
In today's ever-evolving cybersecurity landscape, organizations face an increasing number of threats. Conducting a NIST Cybersecurity Framework (CSF) assessment can be a valuable tool to identify, manage, and mitigate these risks. Let's explore how it can benefit your organization.
A NIST CSF assessment is not just about compliance; it's about proactively managing your cybersecurity posture. By identifying and addressing your vulnerabilities, you can reduce the likelihood and impact of cyberattacks. Additionally, the framework can help you communicate your security efforts effectively to internal and external stakeholders.
UW-Madison, Information Systems 371 - Decision Support SystemsNicholas Davis
Today, is Information Systems 371, I am lecturing about Decision Support Systems. In addition to covering the basics at a conceptual level, I am trying to get the students to think about the impact of IoT, 5G, and Artificial Intelligence, in terms of how Decision Support Systems are changing and what the new demands placed upon them will be.
This document summarizes a university lecture on blockchain and bitcoin. It begins with an overview of how the term "blockchain technology" can refer to different things like the Bitcoin blockchain, other cryptocurrencies, or smart contracts. It then defines what a blockchain is, including that it usually contains financial transactions, is replicated across peer-to-peer networks, and uses cryptography to prove identity and enforce access rights. The document contrasts public and private blockchains and how they differ in terms of who can write to the ledger. It also discusses key concepts like how blockchains achieve consensus when multiple blocks are created simultaneously and how network rules and upgrades are handled.
During the Spring semester, I teach a 3 credit survey course in software development, at UW-Madison (IS 371), which is the first in the series of courses in the Information Systems major track. As part of this course, I devote an entire lecture to discussing different types of software development (Agile, Waterfall, Extreme, Spiral, etc.) I hope it helps the students better understand the different types of software development styles, as well as the benefits and drawbacks of each. In my opinion, they need to learn early on that there is more than one way to go about a software development challenge, and they need to figure out which style works best for them.
Information systems 365 - Cloud and BYOD SecurityNicholas Davis
Today, in class, I will be covering the topics of Cloud and BYOD Information Security. The intent of the lecture is to introduce students to the general issues surrounding information security in these two areas.

Bringing the Entire Information Security Semester Together With a Team ProjectNicholas Davis
Absorbing information does no good, unless you are able to apply what you have learned. Each semester, I give my information security students a team project, in which they must use all the knowledge acquired during the semester, in combination with their ability to do Internet research, to deliver an overall information security assessment of a company of their choosing. To make it a challenge, I make them grade all the other teams in the class, but only give them enough points to distribute so that the average is 90. In grading their peers, they must make decisions about which presentations are excellent, and which are not.

HijackLoader Evolution: Interactive Process HollowingDonato Onofri
CrowdStrike researchers have identified a HijackLoader (aka IDAT Loader) sample that employs sophisticated evasion techniques to enhance the complexity of the threat. HijackLoader, an increasingly popular tool among adversaries for deploying additional payloads and tooling, continues to evolve as its developers experiment and enhance its capabilities.
In their analysis of a recent HijackLoader sample, CrowdStrike researchers discovered new techniques designed to increase the defense evasion capabilities of the loader. The malware developer used a standard process hollowing technique coupled with an additional trigger that was activated by the parent process writing to a pipe. This new approach, called "Interactive Process Hollowing", has the potential to make defense evasion stealthier.

4. Some DefinitionsSome Definitions
Deep Web, Deep Net, Invisible Web, or
Hidden Web is not part of the Surface
Web (that which is normally accessed).
Do not confuse it with the Dark Internet,
which refers to computers which can no
longer be reached over the Internet
Some people think that the Deep Web is
a haven for serious criminality, and I
agree with them

5. Normal Web SearchNormal Web Search
vs. Deep Web Searchvs. Deep Web Search
Searching on the Internet today can be
compared to dragging a net across the
surface of the ocean: a great deal may be
caught in the net, but there is a wealth of
information that is deep and therefore
missed
10/26/16 UNIVERSITY OF WISCONSIN 5
6. Normal Web SearchNormal Web Search
vs. Deep Web Searchvs. Deep Web Search
Traditional search engines cannot see or
retrieve content in the deep Web—those
pages do not exist until they are created
dynamically as the result of a specific
search. As of 2001, the deep Web was
several orders of magnitude larger than
the surface Web
10/26/16 UNIVERSITY OF WISCONSIN 6
7. Deep Web SizeDeep Web Size
It is impossible to measure
or put estimates onto the
size of the deep web
because the majority of the
information is hidden or
locked inside databases.
Early estimates suggested
that the deep web is 4,000
to 5,000 times larger than
the surface web

Dynamic ContentDynamic Content
Dynamic pages which are returned in
response to a submitted query or
accessed only through a form, especially
if open-domain input elements (such as
text fields) are used; such fields are hard
to navigate without domain knowledge.

15. Accessing the Deep WebAccessing the Deep Web
While it is not always possible to
discover a specific web server's external
IP address, theoretically almost any site
can be accessed via its IP address,
regardless of whether or not it has been
indexed.
10/26/16 UNIVERSITY OF WISCONSIN 15
16. Accessing the Deep WebAccessing the Deep Web
Certain content is
intentionally hidden from
the regular internet,
accessible only with special
software, such as Tor. Tor
allows users to access
websites using the .onion
host suffix anonymously,
hiding their IP address.
Other such software includes
I2P and Freenet.

17. The Onion Router (Tor)The Onion Router (Tor)
Tool For the Deep WebTool For the Deep Web
Tor is software that installs into your
browser and sets up the specific
connections you need to access dark
Web sites. Critically, Tor is an encrypted
technology that helps people maintain
anonymity online. It does this in part by
routing connections through servers
around the world, making them much
harder to track.
10/26/16 UNIVERSITY OF WISCONSIN 17
18. Who Invented Tor?Who Invented Tor?
Oddly enough, Tor is the result of research
done by the U.S. Naval Research
Laboratory, which created Tor for political
dissidents and whistleblowers, allowing
them to communicate without fear of
reprisal.

.onion.onion
.onion is a pseudo-top-level domain host
suffix designating an anonymous hidden
service reachable via the Tor network.
Such addresses are not actual DNS
names, and the .onion TLD is not in the
Internet DNS root, but with the
appropriate proxy software installed,
Internet programs such as Web
browsers can access sites with .onion
addresses by sending the request
through the network of Tor servers.

Deep Web links
appear as a random

23. Searching the Deep WebSearching the Deep Web
To discover content on the
Web, search engines use web
crawlers that follow
hyperlinks through known
protocol virtual port
numbers. This technique is
ideal for discovering
resources on the surface
Web but is often ineffective
at finding Deep Web
resources.

Came Here For, Tonight!Came Here For, Tonight!
Just like general web search, searching
the Invisible Web is also about looking
for the needle in the haystack. Only
here, the haystack is much bigger. The
Invisible Web is definitely not for the
casual searcher. It is a deep but not dark
because if you know what you are
searching for, enlightenment is a few
keywords away.
