This video module presents an introduction to cryptography - the method of sending messages in such a way that only the intended recipients can understand them. In this very interactive lesson, students will build three different devices for cryptography and will learn how to encrypt and decrypt messages. There are no prerequisites for this lesson, and it has intentionally been designed in a way that can be adapted to many audiences. It is fully appropriate in a high school level math or computer science class where the teacher can use it to motivate probability/statistics or programming exercises. nteractive lesson, students will learn to build the cryptography devices and will learn how to send and ''crack'' secret messages.

Have you ever felt uneasy or even dreadful after losing a USB flash drive that might contain sensitive information or data about your business?

This presentation will give you a tool to put you at ease when backing up a large number of files and data to a USB flash drive or stick. The tool is relatively easy to use on a USB drive, is based on encryption technology, and protects your business data from the prying eyes.

Attendees will learn about the following topics:
- A brief introduction to data encryption.
- A few encryption tools for a novice user.
- Demonstration on how to use an encryption/decryption tool called VeraCrypt to protect the data on a USB
flash drive.
- Pros and cons of encryption/decryption technology.

Today many small businesses benefit from QuickBooks (Desktop and Online) as a financial accounting and management tool to support their businesses. Among the number of business risks to manage, the protection of the financial data in QuickBooks is essential to the vitality of a company.

What can small business owners do in QuickBooks to manage these security risks?

Attendees to this webinar will learn about the following topics:
- Introduce a security architectural approach to QuickBooks data protection.
- Learn about the default data integrity protections built into QuickBooks.
- Practice stronger authentication into QuickBooks.
- Practice role-based access on QuickBooks accounting.
- Perform security monitoring and fraud detection using a rarely known native tool within QuickBooks.

Presentation Time: 50 minutes plus 10 minutes on Q&A.

An Encryption activity and worksheet for CS0 students. Part of the CUNY CS04All project.

This course considers the interaction between law, policy, and technology as they relate to the evolving controversies over control of the Internet. In addition, there will be an in-depth treatment of privacy and the notion of "transparency" -- regulations and technologies that govern the use of information, as well as access to information. Topics explored will include:

Legal Background for Regulation of the Internet
Fourth Amendment Law and Electronic Surveillance
Profiling, Data Mining, and the U.S. PATRIOT Act
Technologies for Anonymity and Transparency
The Policy-Aware Web

This course focuses on the fundamentals of information security that are used in protecting both the information present in computer storage as well as information traveling over computer networks. Upon successful completion of this course, the student will be able to: explain the challenges and scope of information security; explain such basic security concepts as confidentiality, integrity, and availability, which are used frequently in the field of information security; explain the importance of cryptographic algorithms used in information security in the context of the overall information technology (IT) industry; identify and explain symmetric algorithms for encryption-based security of information; identify and explain public key-based asymmetric algorithms for encryption-based security of information; describe the access control mechanism used for user authentication and authorization; describe Secure Sockets Layer (SSL) as a common solution enabling security of many applications, including all Internet-based commerce; describe securing Internet Protocol (IP) communications by using Internet Protocol Security (IPSec); explain the importance of physical security and discuss ways to improve physical security of an enterprise; explain the use of such security tools as firewalls and intrusion prevention systems; explain malicious software issues, such as those brought forth by software-based viruses and worms; explain common software security issues, such as buffer overflow; describe the basic process of risk assessment in the context of overall IT security management.

6.857 Network and Computer Security is an upper-level undergraduate, first-year graduate course on network and computer security. It fits within the Computer Systems and Architecture Engineering concentration.

This resource guide was created as an accompaniment for a hands-on, three-hour workshop on the basics of online privacy and security in a Canadian context. The workshop is designed for young adults and adults with basic computer/phone/online skills: we assume participants know how to get online, how to do basic internet searches, and how to install simple tools and software on their devices. The workshop is most often taught in public library settings.

This guide provides:
- an overview of security and privacy
- information about key privacy technologies including ad blockers, tracking detection, basic encryption tools, secure messaging tools and password management
- some "advanced" information on Virtual Private Networks (VPNs), Tor, private email services, and more
- instructional guides for basic tools, customized for Windows, MacOS, Android, iOS and ChromeOS devices

This unit covers common security concerns and safeguards, including firewalls, encryption, virus protection software and patterns, and programming for security. Additional topics include security of wireless networks, and concerns, mitigations, and regulations related to healthcare applications.

Students become familiar with the concept of a communication system, its various parts and functions. To do this, they encode, decode, transmit, receive and store messages for a hypothetical rescue mission, using a code sheet and flashlight for this process.They also maintain storage sheets from which they can retrieve information as it is required.
