How many times your project was jammed because it depended on other project, shared resources with other projects, or simply waiting for something that others from your company had to provide? It’s like you are driving a car on the roads with no signs, no rules, but with police to blame you.
How many times did you tried to implement rules from the book? It like reading Grunf’s (Alan Ford) advices “If you want to win, you must not lose”.
So: How to do it? Which is the right way? How much it will cost? How long it takes? What we will gain? Come to share ideas and experience

Many thanks to Sam Bowne for allowing to publish these presentations.
With the explosion of the public Internet and e-commerce, private computers and computer networks, if not adequately secured are increasingly vulnerable to damaging attacks. Hackers, viruses, vindictive employees and even human error all represent
clear and present dangers to networks. And all computer users from the most casual Internet surfers to large enterprises could be affected by network security breaches. However, security breaches can often be easily prevented. How? This white paper provides you an overview of the most common network security threats and its solution which protects you and your organization from threats, hackers and ensures that the
data traveling across your networks is safe.
DEFENSE MECHANISMS FOR COMPUTER-BASED INFORMATION SYSTEMS IJNSA Journal
Nowadays, corporations and a government agencies relay on computer-based information system to manage their information, this information may be classified, so it will be dangerous if it is disclosed by unauthorized persons. Therefore, there is urgent need for defense. In this research, defense has been categorized into four mechanisms technical defense, operation defense, management defense, and physical defense based on the logic of computer and network security. Also, each mechanism has been investigated and explained in the term of computer based information systems.
Answer the following questions. Each question response should be at .docxspoonerneddy
Answer the following questions. Each question response should be at least 1 page, and answer each question fully.
Question 1:
Topic: Common Software Vulnerabilities
Most cyber-attacks happen because vulnerabilities in system or application software. Buffer Overflow, SQL Injection, Code/OS Command Injection, Cross-Site Scripting (XSS), Cross-Site Request Forgery and Race Conditions are very common vulnerabilities. (Refer to both NIST/DHS and MITRE databases of common vulnerabilities (http://nvd.nist.gov/cwe.cfm; http://cwe.mitre.org/top25/).) For this conference, explain what a specific vulnerability is, describe a famous attack that leveraged it (For example, the Morris worm leveraged the buffer overflow vulnerability), and how it can be prevented/minimized.
Question 2:
Topic: Database Security
In this session, you learnt a lot about database security. We will focus three topics for this conference: (1) Inference in ordinary databases or statistical databases, (2) database privacy (through encryption), and (3) cloud security. Please pick one of these three topics and explain in your own words what the problem or issue is, how the issue is being addressed and some of the concerns with the solutions being proposed.
Question 3:
Topic: Attacks on Networks
In this conference, we will focus on typical attacks in the Internet affecting confidentiality, integrity and availability at various layers: Layer 1: Physical; Layer 2: Link; Layer 3: Network; Layer 4: Transport, and Layer 5: Application. (This is IP Layering; in IP layering, roughly Session, Presentation and Application of the OSI layers are combined into a single Application layer). Pick one layer and describe typical attacks in that layer and the controls that are employed in the layer to minimize the attack or vulnerability that leads to the attack. For example, in the link and network layers, there can be packet sniffing attacks, in the IP (network layer), there could be spoofing attacks, and in various layers, there could be denial of service attacks. Be as specific and as complete as possible and cite your reference materials in your response.

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.
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.
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.

Network Security
1 Network Security, University of Okara
Lecture 2: Terminologies
4. Threat
Network Security, University of Okara4
A risk of attack, or, chance of getting attacked.
Attack: when a risk/treat is implemented.
Omini-Present Security: more or less all
systems have security aspects that need to be
discussed. So Security Engineering deals with
ALL aspects of security.
Example: ATM (placing metal to fool customers)
5. 4 Common Threats
Network Security, University of Okara5
Common threats in a computer setting include:
Spoofing: the attacker pretends to be somebody
else
Tampering with data: e.g. security settings are
changed to
give an attacker more privileges
Repudiation: a user denies having performed an
action like
mounting an attack
Denial-of-Service: DoS attacks can make for
instance web
sites temporarily unavailable
6. Risk Analysis
Network Security, University of Okara6
1.Identify the assets to protect
2.Find the threats for each asset
3.Prioritize each of these risks
(asset x vulnerability x threat)
4.Implement controls for each risk, or accept it
5.Monitor the effectiveness of these controls and
reiterate
9. Exercise
