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.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

3. W HAT IS CYBER CRIME ?
Cyber crime refers to any crime that involves a
computer/mobile and a network. The computer may have
been used in the commission of a crime, or it may be the
target.
Cyber hackers apply all sorts of techniques (hacking, use
of malware for intercepting data, etc.) in stealing personal
or financial data from their victims, generally from their
computers.
4. HISTORY
The first spam email took place in 1978 when it was sent
out over the ARPANET (Advanced Research Projects Agency
Network).
The first virus was installed on an Apple computer by a high
school student, Rich Skrenta in the year 1982.
5. Cyber Crime refers to all activities done with criminal
intent in cyberspace. These fall into three slots.
Cyberspace is the electronic medium of computer
networks in which online communication takes place.
Those against persons.
Against Business and Non-business organizations.
Crime targeting the government.
6. C LASSIFICATION OF CYBER
CRIME
Computer as a tool
Computer as a target
Computer as an instrumentality
Crime associated with prevalence of computers
7. C OMPUTER AS A TOOL
When the individual is the main target of the crime the
computer can be considered as a tool rather than target.
These crimes are not done by technical experts.
Eg: Spam, cyber stalking , cyber theft etc.
8. C OMPUTER AS A TARGET
These crimes are committed by a selected group of
people with technical knowledge.
Destruction of information in the computer by spreading
virus.
Eg : Defacement, cyber terrorism etc.
9. C OMPUTER AS AN
INSTRUMENTALITY
The crime is committed by manipulating the contents of
computer systems.
With the advent of computer the criminal have started
using the technology as an aid for its perpetuation.
Eg: Drug trafficking, money laundering etc.
10. C RIME ASSOCIATED WITH
PREVALENCE OF COMPUTERS
Copyright violation
Material copied from sources that are not public domain
or compatibly licensed without the permission of
copyright holder.
Copyright violation causes legal issues.
11. T YPES OF CYBER CRIME
Financial crimes
Sale of illegal articles
Online gambling
Intellectual Property crimes
Theft of information contained in electronic form
Email bombing
Key loggers
13. C ONTD .
Hacking
Denial of Service attack
Virus/worm attacks
Logic bombs
Trojan attacks
Internet time theft
Web jacking
14. Financial crime includes credit card frauds, money
laundering, Forgery etc
Money laundering is the process by which large amount
of illegally obtained money is given the appearance of
having originated from a legitimate source
15. Sale of illegal articles includes selling of narcotic
drugs, weapons, wildlife etc to terrorists.
Email bombing refers to sending a large amount of e-
mails to the victim resulting in crashing of victims e-mail
account or mail servers.
Data diddling is a kind of an attack which involves
altering of raw data just before it is processed by a
computer and then changing it back after the processing
is completed.
16. Intellectual Property Crimes includes software piracy,
copyright infringement, trademarks violations etc.
Theft of information contained in electronic from-This
includes information stored in computer hard disks,
removable storage media etc.
Web defacement is usually the substitution of the
original home page of a website with another page
(usually pornographic or defamatory in nature) by a
hacker.
17. Cyber Defamation occurs when defamation takes place
with the help of computers and or the Internet e.g. e-mail
containing defamatory information about that person.
What is defamation?
Defamation is the act of harming the reputation of person
by making a false statement to another.
18. Cyber Stalking refers to the use of the Internet, e-mail, or
other electronic communications devices to stalk another
person.
Stalking generally involves harassing or threatening
behavior that an individual engages in repeatedly, such as
following a person, appearing at a person's home or place
of business, making harassing phone calls, leaving written
messages or objects, or vandalizing a person's property.
19. Denial of Service involves flooding computer resources
with more requests than it can handle. This causes the
resources to crash thereby denying authorized users the
service offered by the resources.
Virus/worm are programs that attach themselves to a
computer or a file and then circulate themselves to other
files and to other computers on a network. They usually
affect the data on a computer, either by altering or
deleting it. Worms, unlike viruses don not need the host
to attach themselves to.
20. Trojan Horse-A Trojan as this program is aptly called, is an
unauthorized program which functions from inside what
seems to be an authorized program, thereby concealing
what it is actually doing.
Internet Time Theft-This connotes the usage by
unauthorized persons of the Internet hours paid for by
another person.
Web jacking-This occurs when someone forcefully takes
control of a website (by cracking the password ). The
actual owner of the website does not have any more
control over what appears on that website.
21. Logic bombs are dependent programs. This implies that
these programs are created to do something only when a
certain event occurs, e.g. some viruses may be termed
logic bombs because they lie dormant all through the year
and become active only on a particular date.
E-Mail spoofing-A spoofed email is one that appears to
originate from one source but actually has been sent from
another source. This can also be termed as E-Mail forging.
22. Salami attacks are used for the commission of financial
crimes. The key here is to make the alteration so
insignificant that in a single case it would go completely
unnoticed e.g. A bank employee inserts a program into
bank’s servers, that deducts a small amount from the
account of every customer.
Clickjacking is a form of cyber attack where the hacker
uses an invisible layer over the embedded web content
(this could be an image, video or button) to intercept and
‘hijack’ you to a mirror website and mine information
from you.
23. Cyber terrorism is the premeditated use of disruptive
activities, or the threat thereof, in cyber space, with the
intention to further social, ideological, religious, political
or similar objectives, or to intimidate any person in
furtherance of such objectives.
Eg: A simple propaganda in the Internet/SMS, that there
will be bomb attacks during the holidays
Mobile pickpocketing (SMS/call fraud), or the ability to
charge a phone bill via SMS billing and phone calls.
Malware uses these mechanisms to steal directly from
user accounts.
24. Keyloggers are regularly used in computers to log all the
strokes a victim makes on the keyboard.
Eg: If a key logger is installed on a computer which is
regularly used for online banking and other financial
transactions then their passwords can be taken without
the knowledge of the user

27. C YBER SECURITY
It is not possible to eliminate cyber crime from the cyber
space. It is quite possible to check them.
Awareness is the first step in protecting yourself.
Invest in Anti-virus, Firewall, and SPAM blocking software
for your PC.
Change passwords on a regular basis
Use complex passwords (include numbers and special
characters)
28. C ONTD .
Do not automatically check boxes before reading the
contents of any agreement of the software.
Avoiding use of unauthorized software.
Avoid opening of unknown emails.
Use internet filtering software.
Data Level Security Using encrypting softwares
Disable remote connectivity (such as Bluetooth)
29. C YBER SECURITY STANDARDS
Cyber security standards are security standards which
enable organizations to practice safe security techniques
to minimize the number of successful cyber security
attacks.
It provides general outlines as well as specific techniques
for implementing cyber security.
Some of the standards are ISO 27002,NERC, NIST,ISO
15408,RFC 2196,ISA-99.
