It also outlines different types of digital certificates and standards related to PKI.
This document provides an overview of cryptography and different cryptographic algorithms. It defines cryptography as scrambling information so it cannot be read by unauthorized individuals. There are three main types of cryptographic algorithms: hash algorithms that create a unique digital fingerprint of data, symmetric algorithms that use the same key to encrypt and decrypt, and asymmetric algorithms that use two related keys (a public and private key). Common symmetric algorithms include AES and DES, while asymmetric algorithms solve the key distribution problem of symmetric cryptography.
This document summarizes authentication methods and password security based on a chapter from the CompTIA Security+ Guide to Network Security Fundamentals. It describes different types of authentication credentials including what users know (passwords), have (tokens, cards, phones), are (biometrics), and do (behavioral patterns). It outlines vulnerabilities in passwords, common attacks, and defenses including complexity, hashing, and salts. Multi-factor authentication using multiple credential types provides stronger security than single-factor passwords alone.
This document discusses access control fundamentals, including definitions of access control, authentication, authorization, and the four main access control models: discretionary access control, mandatory access control, role-based access control, and rule-based access control. It also covers best practices for access control such as separation of duties, job rotation, least privilege, and mandatory vacations. Technologies for implementing access control like access control lists, group policy, and account restrictions are also examined.
The document provides an overview of presentations for chapters in a security guidebook. It states that the presentations cover the chapter objectives and list all objectives at the beginning. The presentations can be customized for class needs and include some figures from the chapters. It then provides an excerpt from Chapter 1 which discusses the challenges of securing information, defines key security concepts, and identifies common types of attackers and basic steps of an attack. It also outlines the five principles of defense: layering, limiting access, diversity, obscurity, and simplicity.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
