A proxy server is a server that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource available from a different server and the proxy server evaluates the request as a way to simplify and control its complexity.

In cryptanalysis and computer security, password cracking is the process of recovering passwords from data that have been stored in or transmitted by a computer system.
How to choose a password that’s hard to crackKlaus Drosch
A good password is usually the first and only line of defense for your important web-services. Choosing a strong and memorable password can be a hassle since those two criteria don’t always go hand in hand. It’s tempting to reuse an old password, slightly modifying it, or even write it down on a text-file in the computer.
In this guide, we will show you how to choose a good password, how to remember it and just how easily bad passwords can get hacked.
Why is password protection a fallacy a point of viewYury Chemerkin
MAKE your password strong, with a unique jumble of letters, numbers and punctuation marks. But memorize it – never write it down. And, oh yes, change it every few months. These instructions are supposed to protect us. But they don’t.

An Enhanced Security System for Web Authentication IJMER
Web authentication has low security in these days. Todays, For Authentication purpose,
Textual passwords are commonly used; however, users do not follow their requirements. Users tend to
choose meaningful words from dictionaries, which make textual passwords easy tobreak and vulnerable
to dictionary or brute force attacks. Also, Textual passwords can be identified by 3rd
party software’s.
Many available graphicalpasswords have a password space that is less than or equal to the textual
passwordspace. Smart cards or tokens can be stolen.There are so many biometric authentications have
been proposed; however, users tend to resistusing biometrics because of their intrusiveness and the effect
on their privacy. Moreover,biometrics cannot be evoked.In this paper, we present and evaluate our
contribution,i.e., the OTP and 3-D password. A one-time password (OTP) is a password that isvalid for
only one login session or transaction. OTPs avoid a number of shortcomingsthat are associated with
traditional (static) passwords. The most important shortcoming that is addressed by OTPs is that, in
contrast to static passwords, they are not vulnerable to replay attacks. It means that a potential intruder
who manages to record an OTPthat was already used to log into a service or to conduct a transaction
will not be able toabuse it, since it will be no longer valid. The 3-D password is a multifactor
authenticationscheme. To be authenticated, we present a 3-D virtual environment where the
usernavigates and interacts with various objects. The sequence of actions and interactionstoward the
objects inside the 3-D environment constructs the user’s 3-D password.
Password Cracking is a technique to gain the access to an organisation.
In this slide, I will tell you the possible ways of cracking and do a live example for Gmail Password Cracking.
Think you're secure? Gaining access to your most valuable systems may be as easy as cracking (or, simply guessing) a password. Be sure you have a well chosen password.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

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.
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.

2. What is a Password?
• A password is a secret word or string of characters that is used for
user authentication to prove identity, or for access approval to gain
access to a resource (example: an access code is a type of password).
• The use of passwords is known to be ancient. Sentries would
challenge those wishing to enter an area or approaching it to supply a
password or watchword, and would only allow a person or group to
pass if they knew the password.
• In modern times, user names and passwords are commonly used by
people during a log in process that controls access to protected
computer operating systems, mobile phones, cable TV
decoders, automated teller machines (ATMs), etc.

3. What is the need of a password?
There are many reasons to use passwords. Here are some common
reasons to use them:
to prevent unauthorized access to important information
to guarantee security of personal information
to prevent unauthorized access to user accounts, such as computer and email
accounts
to be able to use various Internet services securely

4. How does password work?
Whenever we create a login on any website or any stand alone
system/application, we are generally asked for two things one is the username
and other is the password.
The combination of these username and password is then saved into the
database of the system/application.
And when the user tries to log in to that particular system or application, he is
asked for these two things. If the username and the password entered by the
user matches with the password and the username previously stored in the
database, then he/she is granted the access, else the access is prevented.

6. How to Improve Password based
security?
A very simple answer to this question is “to improve the strength of the password”.
But what actually is a good strength to ensure the proper security??
Well, there are some techniques and do’s and don'ts which may ensure a better
security while using password security.
Some of them are discussed in the next slides.

7. I. Creating a strong Password:
We all must create strong passwords which are tough to guess and break. In
order to create strong passwords we shall follow following points.
a) A minimum password length of 12 to 14 characters.
b) Generating passwords randomly where feasible
c) Avoiding passwords based on repetition, dictionary words, letter or number
sequences, usernames, relative or pet names, romantic links (current or past), or
biographical information (e.g., ID numbers, ancestors' names or dates).
d) Including numbers, and symbols in passwords if allowed by the system
e) If the system recognizes case as significant, using capital and lower-case letters
f) Avoiding using the same password for multiple sites or purposes
g) Avoid using something that the public or workmates know you strongly like or dislike

8. 2. Storing Encrypted Password:
• When we are planning to authenticate users via passwords, we must ensure the security of the
password in our database.
• If we store user passwords as plaintext, against which to compare user log on attempts. If an
attacker gains access to such an internal password store, all passwords—and so all user
accounts—will be compromised. If some users employ the same password for accounts on
different systems, those will be compromised as well.
• More secure systems store each password in a cryptographically protected form, so access to the
actual password will still be difficult for a snooper who gains internal access to the system, while
validation of user access attempts remains possible.
• A common approach stores only a "hashed" form of the plaintext password. When a user types in
a password on such a system, the password handling software runs through a cryptographic hash
algorithm, and if the hash value generated from the user's entry matches the hash stored in the
password database, the user is permitted access.

9. 3. Random Passwords:
• Random passwords consist of a string of symbols of specified length taken from some set of
symbols using a random selection process in which each symbol is equally likely to be
selected. The symbols can be individual characters from a character set (e.g., the ASCII
character set), pronounceable passwords, or even words from a word list (thus forming a
passphrase).
• However, these are often not truly random, but pseudo random
• Random password programs often have the ability to ensure that the resulting password
complies with a local Password Policy.
Brought To You by www.rareinput.com
10. 4. Password longevity (ageing):
• "Password aging" is a feature of some operating systems which forces users to change
passwords frequently (e.g., quarterly, monthly or even more often)
• There is often an increase in the people who note down the password and leave it where it
can easily be found or Users may use simpler passwords or develop variation patterns on a
consistent theme to keep their passwords memorable. Because of these issues, password
aging is effective.
• Password aging is also required because of the nature of data of the IT systems.
Brought To You by www.rareinput.com
11. 5. Limits on the number of password guesses:
• An alternative to limiting the rate at which an attacker can make guesses on a password is to
limit the total number of guesses that can be made.
• The password can be disabled, requiring a reset, after a small number of consecutive bad
guesses (say 5); and the user may be required to change the password after a larger
cumulative number of bad guesses (say 30), to prevent an attacker from making an arbitrarily
large number of bad guesses by interspersing them between good guesses made by the
legitimate password owner.
Brought To You by www.rareinput.com
12. 6. Transmission through encrypted channels:
• The risk of interception of passwords sent over the Internet can be reduced by, among other
approaches, using cryptographic protection.
• The most widely used is the Transport Layer Security (TLS, previously called SSL) feature built
into most current Internet browsers.
• Most browsers alert the user of a TLS/SSL protected exchange with a server by displaying a
closed lock icon, or some other sign, when TLS is in use.
