TLS 1.3 is an update to the Transport Layer Security protocol that improves security and privacy. It removes vulnerable optional parts of TLS 1.2 and only supports strong ciphers to implement perfect forward secrecy. The handshake process is also significantly shortened. TLS 1.3 provides security benefits by removing outdated ciphers and privacy benefits by enabling perfect forward secrecy by default, ensuring only endpoints can decrypt traffic even if server keys are compromised in the future.

Comparative Analysis of Open-SSL Vulnerabilities & Heartbleed Exploit DetectionCSCJournals
Since its introduction in 1994 the Secure Socket Layer (SSL) protocol (later renamed to Transport Layer Security (TLS)) evolved to the de facto standard for securing the transport layer. SSL/TLS can be used for ensuring data confidentiality, integrity and authenticity during transport. A main feature of the protocol is its flexibility. Modes of operation and security aims can easily be configured through different cipher suites. During its evolutionary development process several flaws were found. However, the flexible architecture of SSL/TLS allowed efficient fixes in order to counter the issues. This paper presents an overview on theoretical and practical attacks of the last 20 years.
Study and analysis of some known attacks on transport layer securityNazmul Hossain Rakib
This paper is focused on study on some practically feasible attacks and threats against TLS based connection. The reader can also get an idea on SSL Strip attack presented here based on an experiment in a testbed environment. There are also some other attacks on TLS protocol such as BEAST, Padding Oracle Attack, STARTTLS command injection attack, Theft of RSA Private Keys, Triple Handshake etc. which are also discussed here descriptively. This study summarizes the common known attacks following RFC 7457 and their existence, appliance and remedies for the TLS activated server.

Vulnerability-tolerant Transport Layer Security (vtTLS) - Work presented at OPODIS 2017 on December 20th 2017
SSL/TLS communication channels play a very important role in Internet security, including cloud computing and server infrastructures. There are often concerns about the strength of the encryption mechanisms used in TLS channels. Vulnerabilities can lead to some of the cipher suites once thought to be secure to become insecure and no longer recommended for use or in urgent need of a software update. However, the deprecation/update process is very slow and weeks or months can go by before most web servers and clients are protected, and some servers and clients may never be updated. In the meantime, the communications are at risk of being intercepted and tampered by attackers.
In this presentation (and in the paper) we propose an alternative to TLS to mitigate the problem of secure communication channels being susceptible to attacks due to unexpected vulnerabilities in its mechanisms. Our solution, called Vulnerability-Tolerant Transport Layer Security (vtTLS), is based on diversity and redundancy of cryptographic mechanisms and certificates to ensure a secure communication even when one or more mechanisms are vulnerable. Our solution relies on a combination of k cipher suites which ensure that even if k − 1 cipher suites are insecure or vulnerable, the remaining cipher suite keeps the communication channel secure. The performance and cost of vtTLS were evaluated and compared with OpenSSL, one of the most widely used implementations of TLS.
Why Many Websites are still Insecure (and How to Fix Them)Cloudflare
The latest version of the transport layer security (TLS) protocol was launched at the end of 2017, and version 1.3 proposes the largest change with improvements to performance and security. However, there has not been widespread adoption of this protocol which leaves many users exposed to data and privacy breaches. In this webinar, we will look at the new developments in TLS and SSL, why the internet needs better security and the technical challenges of good encryption.
OSDC 2018 | Hitchhiker’s guide to TLS 1.3 and GnuTLS by Ander Juaristi AlamosNETWAYS
TLS 1.3 is so different from its predecessors, some argue it should’ve been called TLS 2.0. TLS 1.3 comes with a number of new features that may or may not benefit datacenter deployment, depending on the use case. It also streamlines key establishment, making TLS 1.3 simpler, and more secure. It may be the best TLS so far, but in spite of its simplicity fitting it into the current GnuTLS API has been no easy task. This talk gives an overview of what to expect from TLS 1.3, tours around GnuTLS, its interfaces and its internal structure, and explains how we went on redesigning the current API to support TLS 1.3, without breaking anything and of course keeping backward compatibility. Our design principle: TLS 1.3 is simple – so should the interface.

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
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Key Goals of TLS 1.3
Security Benefits
Privacy Benefits
Difference between Handshake in TLS 1.2 & 1.3
3. WHAT IS TLS
THE BEGINNING
OF TRANSPORT
LAYER SECURITY
Probably the Internet’s most important security protocol
Designed over 20 years ago by Netscape for Web transactions
But used for just about everything you can think of
Maintained by the Internet Engineering Task Force
– Back then, called Secure Sockets Layer
– HTTP
– SSL-VPNs
– E-mail
– Voice/video
– IoT
– We’re now at version 1.2
4. WHATS NEW
IN TLS 1.3
TLS 1.3 offers some great improvements over TLS 1.2. Vulnerable optional
parts of the protocol have been removed, there’s support for stronger
ciphers required to implement perfect forward secrecy
(PFS), and the handshake process has been significantly shortened.
In addition, implementing TLS 1.3 should be relatively simple. You can use
the same keys you used for TLS 1.2. Clients and servers will automatically
negotiate a TLS 1.3 handshake when they both support it, and Google
Chrome and Mozilla Firefox already do it by default.
5. TLS ACHIEVES
THIS USING
VARIOUS
TECHNIQUES…
– Symmetric key encryption for application data.
– Typically Advanced Encryption Standard (AES).
PRIVACY
– Authenticated Encryption with Additional Data (AEAD).
– Usually AES-GCM (Galois/Counter Mode) cipher mode.
INTEGRITY
– X509 certificates signed by a mutually trusted third party.
– Typically server authenticated only.
AUTHENTICATION
6. KEY GOALS OF
TLS 1.3
Clean up - Remove unsafe or Unused features
Security - Improve security w/modern techniques
Privacy - Encrypt more of the protocol.
Performance -1-RTT and 0-RTT handshakes
Continuity - Backwards compatibility
7. SECURITY
BENEFITS
Although TLS 1.2 can still be deployed securely, several high-profile
vulnerabilities have exploited optional parts of the protocol and outdated
ciphers. TLS 1.3 removes many of these problematic options and only
includes support for algorithms with no known vulnerabilities (at this time).
The IETF chose to remove all ciphers that do not support PFS from TLS
connections. These include DES, AESCBC, RC4, and other ciphers less
commonly used.
8. PRIVACY
BENEFITS
TLS 1.3 also enables PFS(Perfect Forward Secrecy) by default.
This cryptographic technique adds another layer of confidentiality
to an encrypted session, ensuring that only the two endpoints can
decrypt the traffic. With PFS, even if a third party were to record
an encrypted session, and later gain access to the server private
key, they could not use that key to decrypt the session.
