Security information and event management

Security information and event management Introduction: Security Information and Event Management (SIEM) automates incident identification and resolution based on built in business rules to help improve compliance and alert staff to critical intrusions. IT audits, standards and regulatory requirements have now become an important part of most enterprises day-to-day responsibilities. As part of that burden, organizations are spending significant time and energy scrutinizing their security and event logs to track which systems have been accessed, by whom, what activity took place and whether it was appropriate. Organizations are increasingly looking towards data-driven automation to help ease the burden. As a result, the SIEM has taken form and has provided focused solutions to the problem. The security information and event management market is driven by an extremely increasing need for customers to meet compliance requirements as well as continued need for real-time awareness of external and internal threats. Customers need to analyze sec urity event data in real time (for threat management) and to analyze and report on log data and primarily this has made security information and event management market more demanding. The market remains fragmented, with no dominant vendor. This report entitled Security Information and Event Management (SIEM) Solutions gives a clear view of the SIEM solutions and whether they can help to improve intrusion detection and response. Following this introduction is the background section which deeply analyzes the evolution of the SIEM, its architecture, its relationship with the log management and the need for SIEM products. In the analysis section, I have analyzed the SIEM functions in detail along with real world examples. Finally the conclusion section summarizes the paper. Background: What is SIEM? Security Information and Event Management solutions are a combination of two different products namely, SIM (security information management) and SEM (security event management). SIEM technology provides real-time analysis of security alerts generated by network hardware and applications. The objective of SIEM is to help companies respond to attacks faster and to organize mountains of log data. SIEM solutions come as software, appliances or managed services. Increasingly, SIEM solutions are being used to log security data and generate reports for compliance purposes. Though Security Information and Event Management and log management tools have been complementary for years, the technologies are expected to merge. Evolution of SIEM: SIEM emerged as companies found themselves spending a lot of money on intrusion detection/prevention systems (IDS/IPS). These systems were helpful in detecting external attacks, but because of the reliance on signature-based engines, a large number of false positives were generated. The first-generation SIEM technology was designed to reduce this signal-to-noise ratio and helped to capture the most critical external threats. Using rule-based correlation, SIEM helped IT detect real attacks by focusing on a subset of firewall and IDS/IPS events that were in violation of policy. Traditionally, SIEM solutions have been expensive and time-intensive to maintain and tweak, but they solve the big headache of sorting through excessive false alerts and they effectively protect companies from external threats. While that was a step in the right direction, the world got more complicated when new regulations such as the Sarbanes-Oxley Act and the Payment Card Industry Data Security Standard follo wed much stricter internal IT controls and assessment. To satisfy these requirements, organizations are required to collect, analyze, report on and archive all logs to monitor activities inside their IT infrastructures. The idea is not only to detect external threats, but also to provide periodic reports of user activities and create forensics reports surrounding a given incident. Though SIEM technologies collect logs, they process only a subset of data related to security breaches. They werent designed to handle the sheer volume of log data generated from all IT components, such as applications, switches, routers, databases, firewalls, operating systems, IDS/IPS and Web proxies. With an idea to monitor user activities rather than external threats, log management entered the market as a technology with architecture to handle much larger volumes of data and with the ability to extend to meet the demands of the largest enterprises. Companies implement log management and SIEM solutions to satisfy different business requirements, and they have also find out that the two technologies work well together. Log management tools are designed to collect report and archive a large volume and breadth of log data , whereas SIEM solutions are designed to correlate a subset of log data to point out the most critical security events. On looking at an enterprise IT arsenal, it is likely to see both log management and SIEM. Log management tools often assume the role of a log data warehouse that filters and forwards the necessary log data to SIEM solutions for correlation. This combination helps in optimizing the return on investment while also reducing the cost for implementing SIEM. In these tough economic times it is likely to see IT trying to stretch its logging technologies to solve even more problems. It will expect its log management and SIEM technologies to work closer together and reduce overlapping functionalities. Relation between SIEM and log management: Like many things in the IT industry, theres a lot of market positioning and buzz coming around regarding how the original term of SIM (Security Information Management), the subsequent marketing term SEM (Security Event Management), the newer combined term of SIEM (Security Information and Event Management) relate to the long standing process of log management. The basics of log management are not new. Operating systems, devices and applications all generate logs of some sort that contain system-specific events and notifications. The information in logs may vary in overall usefulness, but before one can derive much value out of them, they first need to be enabled, then transported and eventually stored. Therefore the way that one does gather this data from an often distributed range of systems and get it into a centralized (or at least semi-centralized) location is the first challenge of log management that counts. There are varying techniques to accomplish centralization, ranging from standardizing on the syslog mechanism and then deploying centralized syslog servers, to using commercial products to address the log data acquisition, transport and storage issues. Some of the other issues in log management include working around network bottlenecks, establishing reliable event transport (such as syslog over UDP), setting requirements around encryption, and managing the raw data storage issues. So the first steps in this process are figuring out what type of log and event information is in need to gather, how to transport it, and where to store it. But that leads to another major consideration about what should one person want to do with all those data. It is at this point where the basic log management ends and the higher-level functions associated with SIEM begins. SIEM products typically provide many of the features that remain essential for log management but add event-reduction, alerting and real-time analysis capabilities. They provide the layer of technology that allows one to say with confidence that not only are logs being gathered but they are also being reviewed. SIEM also allows for the importation of data that isnt necessarily even t-driven (such as vulnerability scanning reports) and it is known as the Information portion of SIEM. SIEM architecture: Long term log management and forensic queries need a database built for capacity, with file management and compression tools. Short term threat analysis and correlation need real time data, CPU and RAM. The solution for this is as follows: >Split the feeds to two concurrent engines. >Optimize one for real time and storage up to 30 days of data. (100-300GB) >Optimize the second for log compression, retention, and query functions. (1TB+) The block diagram showing the architecture of the SIEM is as follows: [Source: Reference 2] A collector is a process that gathers data. Collectors are produced in many shapes and sizes from agents that run on the monitored device, to centralized logging devices with pre-processors to split stream the data. These can be simple REGEX file parsing applications, or complex agents for OPSEC, LEA, for .Net/WMI, SDEE/RDEP, or ODBC/SQL queries. Not all security devices are kind enough to forward data, and multiple input methods, including active pull capabilities, are very essential. Also, since SYSLOG data is not encrypted, it may need a collector to provide encrypted transport. A threat analysis engine will need to run in real time, continuously processing and correlating events of interest passed to it by the collector, and reporting to a console or presentation layer application about the threats found. Typically reporting events that has happened for 30 days are sufficient for operational considerations. A log manager will need to store a great deal of data, and may take either raw logs or filtered events of interest, and need to compress store and index the data for long term forensic analysis and compliance reporting. Capacity for 18 months or more of data is likely to be required. Year end closing of books and the arrival of the auditors often necessitate the need for 12 months of historic data plus padding of several months while books are finalized and an audit to be completed. At the presentation layer a console will present the events to the security staff and managers. This is the primary interface to the system for day to day operations, and should efficiently prioritize and present the events with a full history and correlation rationale. SIEM functions: With some subtle differences, there are four major functions of SIEM solutions. They are as follows: 1. Log Consolidation centralized logging to a server 2. Threat Correlation the artificial intelligence used to sort through multiple logs and log entries to identify attackers 3. Incident Management workflow What happens once a threat is identified? (link from identification to containment and eradication). Notification email, pagers, informs to enterprise managers (MOM, HP Openview) Trouble Ticket Creation Automated responses execution of scripts (instrumentation) Response and Remediation logging 4. Reporting Operational Efficiency/Effectiveness Compliance / SOX, HIPPA, FISMA. Ad Hoc / Forensic Investigations Coming to the business case for SIEM, all engineers are perpetually drawn to new technology, but purchasing decisions should by necessity be based on need and practicality. Even though the functions provided by SIEM are impressive they must be chosen only if they fit an enterprises needs. Why use a SIEM? There are two branches on the SIEM tree namely, operational efficiency and effectiveness, and log management/compliance. Both are achievable with a good SIEM tool. However since there is a large body of work on log management, and compliance has multiple branches, this coursework will focus only on using a SIEM tool effectively to point out the real attackers, and the worst threats to improve security operations efficiency and effectiveness. It can be believed that the most compelling reason for a SIEM tool from an operational perspective is to reduce the number of security events on any given day to a manageable, actionable list, and to automate analysis such that real attacks and intruders can be discerned. As a whole, the number of IT professionals, and security focused individuals at any given company has decreased relative to the complexity and capabilities demanded by an increasingly inter networked web. While one solution may have dozens of highly skilled security engineers on staff pouring through individual event logs to identify threats, SIEM attempts to automate that process and can achieve a legitimate reduction of 99.9+% of security event data while it actually increases the effective detection over traditional human driven monitoring. This is why SIEM is preferred by most of the companies. Reasons to use a SIEM: To know the need for a SIEM tool in an organization is very important. A defense in depth strategy (industry best practice) utilizes multiple devices: Firewalls, IDS, AV, AAA, VPN, User Events LDAP/NDS/NIS/X.500, Operating System Logs which can easily generate hundreds of thousands of events per day, in some cases, even millions. No matter how good a security engineer is, about 1,000 events per day is a practical maximum that a security engineer is about to deal with. So if the security team is to remain small they will need to be equipped with a good SIEM tool. No matter how good an individual device is, if not monitored and correlated, each device can be bypassed individually, and the total security capabilities of a system will not exceed its weakest link. When monitored as a whole, with cross device correlation, each device will signal an alert as it is attacked raising awareness and threat indications at each point allowing for additional defences to be brought into play, and i ncident response proportional to the total threat. Even some of the small and medium businesses with just a few devices are seeing over 100,000 events per day. This has become usual in most of the companies says the internet. Real world examples: Below are event and threat alert numbers from two different sites currently running with 99.xx% correlation efficiency on over 100,000 events per day, among which one industry expert referred to as amateur level, stating that 99.99 or 99.999+% efficiency on well in excess of 1,000,000 events per day is more common. Manufacturing Company Central USA 24 hour average, un-tuned SIEM day of deployment Alarms Generated 3722 Correlation Efficiency 99.06% Critical / Major Level Alerts 170 Effective Efficiency 99.96% [Source: Reference 2] In this case, using a SIEM allows the companys security team (2 people in an IT staff of 5), to respond to 170 critical and major alerts per day (likely to decrease as the worst offenders are firewalled out, and the worst offenses dealt with), rather than nearly 400,000. Financial Services Organization 94,600 events 153 actionable alerts 99.83% reduction. [Source: Reference 2] The company above deals with a very large volume of financial transactions, and a missed threat can mean real monetary losses. With respect to the Business Case, a good SIEM tool can provide the analytics, and the knowledge of a good security engineer can be automated and repeated against a mountain of events from a range of devices. Instead of 1,000 events per day, an engineer with a SIEM tool can handle 100,000 events per day (or more). And a SIEM does not leave at night, find another job, take a break or take vacations. It will be working always. SIEM Selection Criteria: The first thing one should look at is the goal. (i.e.) what should the SIEM do for them. If you just need log management then make the vendor can import data from ALL of the available log sources. Not all events are sent via SYSLOG. Some may be sent through: Checkpoint LEA Cisco IDS RDEP/SDEE encryption Vulnerability Scanner Databases Nessus, Eeye, ISS AS/400 Mainframes flat files Databases ODBC/SQL queries Microsoft .Net/WMI Consider a product that has a defined data collection process that can pull data (queries, retrieve files, WMI api calls), as well as accept input sent to it. And it is essential to be aware that logs, standards, and formats change, several (but not all), vendors can adapt by parsing files with REGEX and importing if one can get them a file. However log management itself is not usually an end goal. It matters about for what purpose these logs are used for. They may be used for threat identification, compliance reporting or forensics. It is also essential to know whether the data captured is in real-time. If threat identification is the primary goal, 99+% correlation/consolidation/aggregation is easily achievable, and when properly tuned, 99.99+% efficiency is within reach (1-10 actionable threat alerts / 100,000 events). If compliance reporting is the primary goal, then consider what regulations one is subject to. Frequently a company is subject to multiple compliance requirements. Consider a fortune 500 company like General Electrics. As a publicly traded company GE is subject to SOX, as a vendor of medical equipment and software they are subject to HIPPA, as a vendor to the Department of Defense, they are subject to FISMA. In point of fact, GE must produce compliance reports for at least one corporate division for nearly each and every regulation. Two brief notes on compliance, and one should look at architecture: Beware of vendors with canned reports. While they may be very appealing, and sound like a solution, valid compliance and auditing is about matching output to ones stated policies, and must be customized to match each companys published policies. Any SIEM that can collect all of the required data, meet ISO 177999, and provide timely monitoring can be used to aid in compliance. Compliance i s a complex issue with many management, and financial process requirements, it is not just a function or report IT can provide. Advanced SIEM Topics: Risk Based Correlation / Risk Profiling Correlation based on risk can dramatically reduce the number of rules required for effective threat identification. The threat and target profiles do most of the work. If the attacks are risk profiled, three relatively simple correlation rules can identify 99%+ of the attacks. They are as follows: IP Attacker repeat offenders IP Target repeat targets Vulnerability Scan + IDS Signature match Single Packet of Doom Risk Based Threat Identification is one of the more effective and interesting correlation methods, but has several requirements: >A Metabase of Signatures Cisco calls the attack X, ISS calls it Y, Snort calls it Z Cross Reference the data >Requires automated method to keep up to date. >Threats must be compiled and threat weightings applied to each signature/event. Reconnaissance events are low weighting but aggregate and report on the persistent (low and slow) attacker Finger Printing a bit more specific, a bit higher weighting Failed User Login events a medium weighting, could be an unauthorized attempt to access a resource, or a forgotten password. Buffer Overflows, Worms and Viruses -high weighting -potentially destructive events one need to respond to unless one has already patched/protected the system. >The ability to learn or adjust to ones network Input or auto-discover which systems, are business critical vs. which are peripherals, desktops, and non-essential >Risk Profiling: Proper application of trust weightings to reporting devices (NIST 800-42 best practice), can also help to lower cry wolf issues with current security management Next-generation SIEM and log management: One area where the tools can provide the most needed help is in compliance. Corporations increasingly face the challenge of staying accountable to customers, employees and shareholders, and that means protecting IT infrastructure, customer and corporate data, and complying with rules and regulations as defined by the government and industry. Regulatory compliance is here to stay, and under the Obama administration, corporate accountability requirements are likely to grow. Log management and SIEM correlation technologies can work together to provide more comprehensive views to help companies satisfy their regulatory compliance requirements, make their IT and business processes more efficient and reduce management and technology costs in the process. IT organizations also will expect log management and intelligence technologies to provide more value to business activity monitoring and business intelligence. Though SIEM will continue to capture security-related data, its correlation engine can be re-appropriated to correlate business processes and monitor internal events related to performance, uptime, capability utilization and service-level management. We will see the combined solutions provide deeper insight into not just IT operations but also business processes. For example, we can monitor business processes from step A to Z and, if a step gets missed, well see where and when. In short, by integrating SIEM and log management, it is easy to see how companies can save by de-duplicating efforts and functionality. The functions of collecting, archiving, indexing and correlating log data can be collapsed. That will also lead to savings in the resources required and in the maintenance of the tools. CONCLUSION: SIEM is a complex technology, and the market segment remains in flux. SIEM solutions require a high level of technical expertise and SIEM vendors require extensive partner training and certification. SIEM gets more exciting when one can apply log-based activity data and security-event-inspired correlation to other business problems. Regulatory compliance, business activity monitoring and business intelligence are just the tip of the iceberg. Leading-edge customers are already using the tools to increase visibility and the security of composite Web 2.0 applications, cloud-based services and mobile devices. The key is to start with a central record of user and system activity and build an open architecture that lets different business users access the information to solve different business problems. So there is no doubt in SIEM solutions helping the intrusion detection and response to improve. References: 1. Nicolett.M., Williams.A.T., Proctor.P.E.

Developing Country and Physics

Physics – the study of matter, energy and their interactions – is an international enterprise, which plays a key role in the future progress of humankind. The support of physics education and research in all countries is important because: physics is and exciting intellectual adventure that inspires young people and expands the frontiers of our knowledge about nature.Physics is the most basic of the physical sciences. From chemistry and geology through to biology and cosmology, we understand science in terms of the concepts developed in physics. Not only this, but many of the tools on which the advances of science and technology depend are direct product of physics. The interests and concerns of physicists have always formed the basis of future technology.In medicine we use X-rays, radioisotope and nuclear magnetic resonance imaging. In addition, laser, electron microscopes, synchrotron radiation, and electronics all depend on advances made in physics.Where would our mo dern western economies be without computers?—we could not build the electronics that modern computers rely on without a knowledge of quantum mechanics. Our modern world is much more connected than in previous historical times. These days we travel far, communicate easily and quickly, and conduct business around the world effortlessly. In fact almost no place on earth has been excluded from the modern interconnected world.We are not only connected with physics through modern technology we are connected at a much more basic level through mother nature. The tsunami in Sumatra Indonesia is a prime example. Not only was it catastrophic for the local area the laws of physics saw this tsunami travel across the Indian Ocean killing over 300,000 in Southeast Asia, and traveling through more than 30 other countries resulting in more than 500 deaths. This was the law of physics in action.But as much proof as there is that physics has played an important role in the connectivity of all p arts of the planet the world is still a much divided place. In developed countries you see an almost 100% literacy rate and a $30,000 mean capital income, and a life expectancy of 80. While in developing nations you see a literacy rate lower than 50% and a mean capital income that’s around $2000, and a life expectancy of 40. There is much more for physics, the scientific world, and governments to do to create equality with that interactivity.Kofi Anna the UN Secretary General has been quick to point out the ongoing tragedies throughout the developing world that are directly tied to disease, poverty, and the degradation of the environment. He is also quick to point out that the lack of access to physics and other sciences as well as technology has attributed to many of these problems. Sadly the scientific community spends most of it’s time working on solutions for the developed world yet most of the population on earth can be found in nations that are developing.Physics has the capability of playing a major role in finding solutions to many of the problems facing the human race. Of course it does not have all the answers but the science is developed enough to have created nuclear weapons which remain a global threat, then surely it can be used for the betterment of all people around the globe.Of course politics, socio-economic factors, and acceptance by the people all play a role in the development of a nation. But physics, engineering, and other technological and scientific feats can transform a developing nation to a developed nation. Just look at what the role of physics has accomplished in just the past 200 years. Physics can play an important role in developing strategies to combat climate change, in the development of cleaner energies, and in the development of technological advancements.Then why is it that developing nations spend such a small portion of the GDP on research and development in these areas? Is it because the benefits of scien ce and physics specifically are not fully recognized in industrialized and developing nations? Is it that they really do not want to face the idea that our world is in desperate need of change to ensure we do not destroy ourselves?Physics and technology must work together to resolve the need for new technologies that will decrease the damage to our planet, for strategies  to ensure that the people of developing countries have the tools to progress, the need for solutions to deadly diseases that remain a threat, and the need for solutions to the increasing demands we place on our resources before they are depleted. The role of physics in our modern world is more important than in any other time in history.THE IMPORTANCE OF PHYSICS TO SOCIETYPhysics generates fundamental knowledge needed for the future technological advances that will continue to drive the economic engines of the world. Physics contributes to the technological infrastructure and provides trained personnel needed to take advantage of scientific advances and discoveries. Physics is an important element in the education of chemists, engineers and computer scientists, as well as practitioners of the other physical and biomedical sciences.Physics extends and enhances our understanding of other disciplines, such as the earth, agricultural, chemical, biological, and environmental sciences, plus astrophysics and cosmology – subjects of substantial importance to all peoples of the world. Physics improves our quality of life by providing the basic understanding necessary for developing new instrumentation and techniques for medical applications, such as computer tomography, magnetic resonance imaging, positron emission tomography, ultrasonic imaging, and laser surgery.THE IMPORTANCE OF PHYSICS TO MANPhysics is important to man’s life because it is used in †¢Cooking food †¢Cleaning clothes †¢Watching TV †¢Heating your hose †¢Playing sports †¢Everything else in your life †¢ Physics plays an important role in health †¢ Economic development †¢ Education †¢ Energy and †¢ The environment.Physics has had an increasingly important impact on the average person’s daily life. For example, Physicists played an essential role in the development of: The Transistor-: The basis of all modern electronics, including radio, television, computers, and telecommunications. The Laser And Laser Diodes: Now used widely in CD players, grocerybar code scanners medical treatment, and telecommunications. The Digital Computer–much of the early development (and some of the most recent) have been motivated by basic research.Fiber Optics: Now finding widespread application in high-speed data and voice transmission networks. The Global Positioning System: Uses satellites and precise timing to allow positions to be allocated to within a few feet anywhere on the surface of the earth. The Hologram: Uses on credit card, driver’s licenses, and other documents to prevent fraud.The World Wide Web (W.W.W)–originally designed by physicist for one to be able to access the world. Medical Imaging Techniques: Such as the sonogram, the CAT scan, and Magnetic Resonance Imaging (MRIs). Medical Treatment Techniques: Using radiation and charged particle accelerators. New Micro-Sensors: For â€Å"smart machines† and â€Å"smart buildings,† faster and smaller computers, computer disks that can store information in a smaller space, improved chemical processing to help the environment and reduce energy use, faster and cheaper telecommunications.THE FOLLOWING ARE THE VARIOUS IMPORTANCES OF PHYSICS TO MAN AND THE SOCIETY.Physics Improves Health; In medical technology, positron emission tomography (PET) Lets neurologists see how energy flows inside the brain to see where problems could be occurring.Physics Connects the World; The telecommunications industry, including the development of the internet, has be nefited from physics research in telecommunications from radio waves to fiber optic cable.Physics Improves Technology; The computing industry depends on physics research in semiconductors and magnetism in order to build processors and disk ever smaller and denser.Physics Drives Progress; Physics research benefits the transportation industry in everything from what materials to build cars of to how to build efficient engines to navigating using the global positioning system.Physics Clears the Air; Physics is used in environmental science to both detect problems and to build systems that are better for the environment with technologies such as solar power and plasma physics.Physics Fills the Home; Many consumer goods developed from physics research. CDs are possible because of refinements in laser technology. Many household gadgets have microprocessors such as microwaves and phones.Physics Designs the Future; Research in materials physics has led to many innovations in the substances from which products are made. One now-common material is Teflon ®. Other substances are now used to make many items from sports equipment to earthquake-resistant buildings.PHYSICS LUNCHES NEW BUSINESS;The defense department started the Global Positioning System (GPS), which uses 24 satellites. GPS was possible because of the atomic clock. Now GPS technology has many uses from being in road maps in cars to perceiving shifts in the tectonic plates.PHYSICS IS THE MOST FUNDAMENTAL OF THE SCIENCES;It is concerned with the most basic building blocks of all things – from ants to antennas, from quarks to quasars. The study of physics means trying to find out what the universe is made of, and how these things move and interact with each other. So in one sense, all the other sciences are built on the knowledge gained through the study of physics.PHYSICS IS BEAUTIFUL;Physicists love simplicity. They are constantly striving to find the most fundamental ideas that can be used to describ e even the most complex of phenomena. For example Newton found that only a very small number of concepts could be used to describe just about all of the mechanical world – from steam engines to the motion of the planets. Not only is this beautiful, it's downright amazing!PHYSICS TEACHES YOU TO THINK;This might seem like a strange statement. The study of all subjects teach you to think. But because physics deals with the most basic concepts, the application of such techniques as â€Å"Separation of Variables† and â€Å"The Scientific Method† are never more clear than they are in the study of physics. Once mastered you will find that these methods can be applied to all subjects, including the business world and just coping with everyday life.PHYSICS GIVES YOU A NEW APPRECIATION OF THE WORLD AROUND YOU;You can look a rainbow and say â€Å"Wow, pretty colors!†, or you can marvel at the amazing interactions between photons and electrons that come together in t hat particular way when light from the sun strikes spherical water droplets in the sky, and that you perceive as a multicolored arc suspended in the air. Now that's awe!PHYSICS IS FUN;Lastly, studying physics gives you the opportunity of playing with a lot of really cool toys!IN ADDICTION:Many pioneers in molecular biology were trained as physicists e.g. Francis Crick, one of the two discoverers of  DNA.  A large number of astronomers were also trained as physicist.   Without physics, cars wouldn’t have being developed to take us to our various destinations. TV’s, Light will not have been invented.   We would not have known about space,  Computer Games,  How water boils,  Model financial Market,  Shape futuristic buildings and structures.SUMMARY & CONCLUSIONPhysics is a creative subject,The concepts of physics don't come easily. Someone has to come up with a theory to begin with. This is just as much a creative process as composing music. But where phys ics, and science in general, differ from the Arts is that no one will accept your theory unless you have some way of testing its validity. Experimental physicists sometimes have to be enormously creative in coming up with methods of testing theories and measuring things in the world around them.For example, how do you tell that there is a planet orbiting a star that is so far away that it appears as nothing more than a spec of light in even the most powerful telescopes? In summary, for all these reasons, physics is an essential part of the educational system and of an advanced society. We therefore urge all governments to seek advice from physicists and other scientists on matters of science policy, and to be supportive of the science of Physics.Man has always been inspired by the wonders of nature.   He has always been curious to know the secrets of nature and remained in search. Although physics play an important role to understand this physical world. In our daily life,we hardl y find a device where physics is not involved. Consider pulleys that make it easy to lift a load.Electricity is used not only to get light and heat but also mechanical energy that drive fans and electric motors etc. Consider the means of transportation such as cars and aeroplanes;domestic appliances such as air-conditioners, washing machines and microwave ovens. Physics is important to our daily life because  we use many thing like electricity etc.Our entire existence relies on physics. From energy transference to the gravity keeping us on Earth, we rely on the laws of physics to go by our daily life.In the most general sense, physics is the study of matter, energy, and the interaction between them. It is a very broad field, and is responsible for much of the technology available today.A few examples: †¢An understanding of Newton's Laws allows people to put satellites into orbit, design safer vehicles and build safe buildings. †¢An understanding of electromagnetism allow s people to build electrical circuits and computers. †¢An understanding of the nature of light allows astronomers to determine the composition of stars without ever having to visit them.

Pygmalion by George Bernard Shaw - 950 Words

Pygmalion, written by George Bernard Shaw, is well known for its portrayal of the rich and the poor. At the time of its publication, it was common belief that the poor were morally inferior to the rich. Pygmalion argues the opposite. Bernard Shaw used both static and dynamic characters to demonstrate the equality between the social classes regarding morals and intelligence. In the case of Eliza Doolittle, the differences are seen as she transitions from poverty to the middle class. In Pygmalion, she is shown to be a dynamic character, undergoing many changes of personal strength, articulation, and freedom. Throughout Pygmalion, as Eliza Doolittle increases both her confidence and her self-control, her development of personal inner strength is demonstrated. When Eliza is first introduced at the beginning of the play, she is spirited, but lacks confidence and willpower. By the end of the play, she has become bold, self-assured, and is in control of her actions and behavior.
