Importance Of Cissp Certification

Importance of CISSP certification

by

John Michals

Information technology is being very important for the people in the present society that would help the job seekers to promote themselves in their career. Particularly, there is lots of demand in the information technology for security certification. One such program is CISSP certification and it is otherwise known as certified information system security professionals. This program is particularly designed for the professionals who are in the field of securing a particular specialization in the organization. CISSP certification is awarded from the non- profit organization known as (ISC) 2. (ISC) 2 is known as international information systems security certification consortium. Since it is a security certification, professionals need to answer for 4 questions that are about criminal background as well as history.

As per the reports from (ISC) 2, there are approximately 68,000 professionals who have successfully certified with CISSP certification across the world in 130 countries. Until June 2004, this program was accredited by IEC standard 17024:2003/ ANSI ISO and it was approved from United States Defense Department. The key topics of CISSP program include 10 topics and they are as follows:

Security in application

Access controlling

Planning in disaster recovery and business continuity

Management in Risk as well as security in information systems

Overview of Cryptography

Physical or environmental security

Design as well as security architecture

Operational security

Networking security as well as overview of telecommunication

Compliance, investigations, legal as well as regulations

Candidates can prepare for the examination by concentrating the above topics. For applying CISSP certification, candidates should have certain requirements and they should meet those requirements as well. They are:

It is mandatory for the professionals to have minimum of 2 to 5 years of relevant experience in any of the 10 domains mentioned above. Experience in more than 2 domains will be an added advantage for having this certification.

Professionals should answer 4 questions that are related to criminal background and other related background

The time duration for this examination is around 6 hours and total questions asked are around 250. To pass this exam, minimum of 700 points are required. Lesser than 700 points will result in fail and candidates have to retake the exam unless/ until 700 points or above are being scored. No more re-take will be possible once candidates have passed the examination.

Microsoft and Yahoo! link their instant messaging services

Thursday, July 13, 2006

Nine months after announcing the interoperability between their instant messaging (IM) services, Internet rivals Microsoft and Yahoo! began limited public beta (pre-release) testing of the program. This enables users of the two services to communicate with each other using their existing IM client, Microsoft’s Windows Live Messenger (formerly MSN Messenger) and Yahoo! Messenger with Voice.

Users wishing to use the new feature can go to a special page on the service’s website, where they have to review and accept an agreement. After signing out and signing in again, the interoperability is enabled without downloading any new software.

The service is designed to allow users to see each others’ online presence, view personal status messages, share select emoticons, view offline messages and add new contacts from either service. However, more advanced features, like voice calls and shared folders are not interoperable between the two services.

The program is available internationally in more than 15 markets.

Stanford physicists print smallest-ever letters ‘SU’ at subatomic level of 1.5 nanometres tall

Wednesday, February 4, 2009

A new historic physics record has been set by scientists for exceedingly small writing, opening a new door to computing‘s future. Stanford University physicists have claimed to have written the letters “SU” at sub-atomic size.

Graduate students Christopher Moon, Laila Mattos, Brian Foster and Gabriel Zeltzer, under the direction of assistant professor of physics Hari Manoharan, have produced the world’s smallest lettering, which is approximately 1.5 nanometres tall, using a molecular projector, called Scanning Tunneling Microscope (STM) to push individual carbon monoxide molecules on a copper or silver sheet surface, based on interference of electron energy states.

A nanometre (Greek: ?????, nanos, dwarf; ?????, metr?, count) is a unit of length in the metric system, equal to one billionth of a metre (i.e., 10-9 m or one millionth of a millimetre), and also equals ten Ångström, an internationally recognized non-SI unit of length. It is often associated with the field of nanotechnology.

“We miniaturised their size so drastically that we ended up with the smallest writing in history,” said Manoharan. “S” and “U,” the two letters in honor of their employer have been reduced so tiny in nanoimprint that if used to print out 32 volumes of an Encyclopedia, 2,000 times, the contents would easily fit on a pinhead.

In the world of downsizing, nanoscribes Manoharan and Moon have proven that information, if reduced in size smaller than an atom, can be stored in more compact form than previously thought. In computing jargon, small sizing results to greater speed and better computer data storage.

“Writing really small has a long history. We wondered: What are the limits? How far can you go? Because materials are made of atoms, it was always believed that if you continue scaling down, you’d end up at that fundamental limit. You’d hit a wall,” said Manoharan.

In writing the letters, the Stanford team utilized an electron‘s unique feature of “pinball table for electrons” — its ability to bounce between different quantum states. In the vibration-proof basement lab of Stanford’s Varian Physics Building, the physicists used a Scanning tunneling microscope in encoding the “S” and “U” within the patterns formed by the electron’s activity, called wave function, arranging carbon monoxide molecules in a very specific pattern on a copper or silver sheet surface.

“Imagine [the copper as] a very shallow pool of water into which we put some rocks [the carbon monoxide molecules]. The water waves scatter and interfere off the rocks, making well defined standing wave patterns,” Manoharan noted. If the “rocks” are placed just right, then the shapes of the waves will form any letters in the alphabet, the researchers said. They used the quantum properties of electrons, rather than photons, as their source of illumination.

According to the study, the atoms were ordered in a circular fashion, with a hole in the middle. A flow of electrons was thereafter fired at the copper support, which resulted into a ripple effect in between the existing atoms. These were pushed aside, and a holographic projection of the letters “SU” became visible in the space between them. “What we did is show that the atom is not the limit — that you can go below that,” Manoharan said.

“It’s difficult to properly express the size of their stacked S and U, but the equivalent would be 0.3 nanometres. This is sufficiently small that you could copy out the Encyclopaedia Britannica on the head of a pin not just once, but thousands of times over,” Manoharan and his nanohologram collaborator Christopher Moon explained.

The team has also shown the salient features of the holographic principle, a property of quantum gravity theories which resolves the black hole information paradox within string theory. They stacked “S” and the “U” – two layers, or pages, of information — within the hologram.

The team stressed their discovery was concentrating electrons in space, in essence, a wire, hoping such a structure could be used to wire together a super-fast quantum computer in the future. In essence, “these electron patterns can act as holograms, that pack information into subatomic spaces, which could one day lead to unlimited information storage,” the study states.

The “Conclusion” of the Stanford article goes as follows:

According to theory, a quantum state can encode any amount of information (at zero temperature), requiring only sufficiently high bandwidth and time in which to read it out. In practice, only recently has progress been made towards encoding several bits into the shapes of bosonic single-photon wave functions, which has applications in quantum key distribution. We have experimentally demonstrated that 35 bits can be permanently encoded into a time-independent fermionic state, and that two such states can be simultaneously prepared in the same area of space. We have simulated hundreds of stacked pairs of random 7 times 5-pixel arrays as well as various ideas for pathological bit patterns, and in every case the information was theoretically encodable. In all experimental attempts, extending down to the subatomic regime, the encoding was successful and the data were retrieved at 100% fidelity. We believe the limitations on bit size are approxlambda/4, but surprisingly the information density can be significantly boosted by using higher-energy electrons and stacking multiple pages holographically. Determining the full theoretical and practical limits of this technique—the trade-offs between information content (the number of pages and bits per page), contrast (the number of measurements required per bit to overcome noise), and the number of atoms in the hologram—will involve further work.Quantum holographic encoding in a two-dimensional electron gas, Christopher R. Moon, Laila S. Mattos, Brian K. Foster, Gabriel Zeltzer & Hari C. Manoharan

The team is not the first to design or print small letters, as attempts have been made since as early as 1960. In December 1959, Nobel Prize-winning physicist Richard Feynman, who delivered his now-legendary lecture entitled “There’s Plenty of Room at the Bottom,” promised new opportunities for those who “thought small.”

Feynman was an American physicist known for the path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the superfluidity of supercooled liquid helium, as well as work in particle physics (he proposed the parton model).

Feynman offered two challenges at the annual meeting of the American Physical Society, held that year in Caltech, offering a $1000 prize to the first person to solve each of them. Both challenges involved nanotechnology, and the first prize was won by William McLellan, who solved the first. The first problem required someone to build a working electric motor that would fit inside a cube 1/64 inches on each side. McLellan achieved this feat by November 1960 with his 250-microgram 2000-rpm motor consisting of 13 separate parts.

In 1985, the prize for the second challenge was claimed by Stanford Tom Newman, who, working with electrical engineering professor Fabian Pease, used electron lithography. He wrote or engraved the first page of Charles Dickens’ A Tale of Two Cities, at the required scale, on the head of a pin, with a beam of electrons. The main problem he had before he could claim the prize was finding the text after he had written it; the head of the pin was a huge empty space compared with the text inscribed on it. Such small print could only be read with an electron microscope.

In 1989, however, Stanford lost its record, when Donald Eigler and Erhard Schweizer, scientists at IBM’s Almaden Research Center in San Jose were the first to position or manipulate 35 individual atoms of xenon one at a time to form the letters I, B and M using a STM. The atoms were pushed on the surface of the nickel to create letters 5nm tall.

In 1991, Japanese researchers managed to chisel 1.5 nm-tall characters onto a molybdenum disulphide crystal, using the same STM method. Hitachi, at that time, set the record for the smallest microscopic calligraphy ever designed. The Stanford effort failed to surpass the feat, but it, however, introduced a novel technique. Having equaled Hitachi’s record, the Stanford team went a step further. They used a holographic variation on the IBM technique, for instead of fixing the letters onto a support, the new method created them holographically.

In the scientific breakthrough, the Stanford team has now claimed they have written the smallest letters ever – assembled from subatomic-sized bits as small as 0.3 nanometers, or roughly one third of a billionth of a meter. The new super-mini letters created are 40 times smaller than the original effort and more than four times smaller than the IBM initials, states the paper Quantum holographic encoding in a two-dimensional electron gas, published online in the journal Nature Nanotechnology. The new sub-atomic size letters are around a third of the size of the atomic ones created by Eigler and Schweizer at IBM.

A subatomic particle is an elementary or composite particle smaller than an atom. Particle physics and nuclear physics are concerned with the study of these particles, their interactions, and non-atomic matter. Subatomic particles include the atomic constituents electrons, protons, and neutrons. Protons and neutrons are composite particles, consisting of quarks.

“Everyone can look around and see the growing amount of information we deal with on a daily basis. All that knowledge is out there. For society to move forward, we need a better way to process it, and store it more densely,” Manoharan said. “Although these projections are stable — they’ll last as long as none of the carbon dioxide molecules move — this technique is unlikely to revolutionize storage, as it’s currently a bit too challenging to determine and create the appropriate pattern of molecules to create a desired hologram,” the authors cautioned. Nevertheless, they suggest that “the practical limits of both the technique and the data density it enables merit further research.”

In 2000, it was Hari Manoharan, Christopher Lutz and Donald Eigler who first experimentally observed quantum mirage at the IBM Almaden Research Center in San Jose, California. In physics, a quantum mirage is a peculiar result in quantum chaos. Their study in a paper published in Nature, states they demonstrated that the Kondo resonance signature of a magnetic adatom located at one focus of an elliptically shaped quantum corral could be projected to, and made large at the other focus of the corral.

Want To Be A Doctor? 4 Things You Should Know

byadmin

Earning a medical education in USA can give you a huge competitive edge when you finally go back home. But years of study abroad can take a toll on you. Finding the right program and school can help:

Your average score

Some students apply to schools wherein their average scores are higher than the school’s average. This more than increases their chances of getting accepted into med school. While that’s a good backup plan, make sure you choose schools you like. Otherwise, you could spend the next few years struggling to finish your degree. That or spend more when you switch to another school.

Your ideal location

Where is the school’s US branch or campus? 4 years is a long time. You’ll want to make sure you spend that time in a town, city or state you like. Check out the cost of living in the area. Are the rates student-friendly? What about accommodations? Could you afford to rent an apartment near the campus so you only need to walk to get to and from your classes? This can affect the quality of your life and happiness in med school, says the Prospective Doctor, so make sure you choose with care and caution.

Your special interests

Some schools are better primary care training while others excel at research. Some offer global medicine electives or programs. You’ll want to consider any special interests you have before you choose a school and match that up with the kind of training you want to add to your resume.

Your learning style

What kind of teaching style do you respond to the best? Do you like small group learning? Then you’ll want to look for schools that focus on that. Just want lectures? These are just a few things you’ll need to mull over when you earn a medical education in the USA.

Marxists retain West Bengal, regain Kerala

Thursday, May 11, 2006Marxists retained West Bengal and regained Kerala in assembly elections in 5 Indian states whose results were declared today. Tamil Nadu is likely to have its first coalition government headed by DMK’s leader M Karunanidhi. Assam faces a hung assembly, while the Congress-led Front won overwhelmingly in Pondicherry

The Left Front, led by the Communist Party of India (Marxist), won 235 out of the total 294 assembly seats in West Bengal. West Bengal Chief Minister Buddhadeb Bhattacharjee has scored a thumping victory in Jadavpur, winning by a margin of over 58,000 votes.

“It is our victory. All credit goes to the people,” Bhattacharjee told reporters.

Veteran CPI(M) leader and previous Chief Minister Jyoti Basu hailed the ruling Left Front’s “march to power” in West Bengal for the seventh successive term as “unprecedented in parliamentary history”. Basu was Chief Minister of West Bengal from 1977 to 2000.

Tamil Nadu is likely to have its first coalition government headed by DMK leader M Karunanidhi after Chief Minister Jayalalithaa is voted out of power. The DMK-led front won in 162 out of 230 assembly seats in Tamil Nadu. And for the fifth time, DMK chief M Karunanidhi is all set to become the chief minister of the state.

In Kerala, The Left Democratic Front was victorious in 98 seats out of 140 constituencies. The UDF, which came to power last time with 99 seats, won only 41 seats.

Assam is heading for a hung assembly, whereas in Pondicherry, a Union Territory of India, Indian National Congress-led Front won 20 of 30 seats.

Setting Up A New Site: What Basic Office Supplies In Madison, Wi Are Needed Right Now?

byadmin

Opening an office after running a new business out of a back bedroom is a heady experience. Along with thinking about details like computer equipment and furnishings, it pays to think about what type of basic Office Supplies in Madison WI will be needed immediately. While some things can wait until everyone is settled in, others must be in place for the office to function. Here are some examples to keep in mind.

Copy Paper

Even with the use of file sharing, email, and other electronic means of communication, there is still the need to print some things out for meetings or to prepare paper copies of invoices. Always make sure copy paper is on that list of basic Office Supplies in Madison WI and ensure there is plenty before the office officially opens. Doing so ensures the employees can get right to work without having to wait for the paper to be delivered.

Printer Cartridges

Cartridges for every printer in the office must be in place. Fresh cartridges should be in those printers, and the supply closet should sport at least one compatible cartridge for each of those devices. If the office functioned with the use of one central printer, it wouldn’t hurt to hold two in reserve.

Note Pads

The ability to quickly write out a note that can be passed down the conference room table during an audio conference or to take a message from a caller who despises voice mail is always helpful. That means having something to write on when those occasions arise. Good, old-fashioned note pads do the job.

Pens and Pencils

Jotting down notes during a phone conversation is still one of the more common tasks associated with office work. Jotting is a lot easier if there is a pen or pencil handy to go with those note pads. Pay close attention to the quality and spend a little more up front. The last thing anyone needs is a pen that won’t write or a pencil lead that breaks every time someone tries to use it.

The expense of opening a new office is significant. Learn more about us and how to prioritize the selection of supplies. Once the office is up and running, there will be time to think about purchasing other supplies that are needed less frequently.

Iranian International Master Dorsa Derakhshani discusses her chess career with Wikinews

Tuesday, April 14, 2020

In February 2017, the Iranian Chess Federation announced two teenage chess players, Dorsa Derakhshani and her younger brother Borna Derakhshani, were banned from representing the national team. The federation announced their decision although Dorsa Derakhshani had previously decided and informed the chess federation she did not wish to play for Iran.

Dorsa Derakhshani is currently 21 years old and holds the International Master (IM) as well as Woman Grand Master (WGM) titles. Her brother, Borna, plays for the English Federation and holds the FIDE Master title.

Dorsa Derakhshani was banned since she did not wear a hijab, an Islamic headscarf, while competing at the Tradewise Gibraltar Chess Festival in January 2017. Under the laws of Islamic Republic of Iran, hijab is a mandatory dress code. Her brother Borna Deraskhsani was banned for playing against Israeli Grand Master (GM) Alexander Huzman at the same tournament. Iran does not recognise the existence of Israel, and previously, Irani athletes have avoided playing against Israeli athletes.

Mehrdad Pahlavanzadeh, the president of the country’s chess federation, explained the decision to ban the players saying, “As a first step, these two will be denied entry to all tournaments taking place in Iran and in the name of Iran, they will no longer be allowed the opportunity to be present on the national team.” ((fa))Farsi language: ?????? ????? ?? ??? ??? ?? ??? ????? ?? ?? ???? ???????? ?? ?? ????? ? ?? ??? ????? ?????? ??????? ????? ??????? ? ???? ???? ???? ?? ??? ??? ?? ??????? ????. He further stated, “Unfortunately, something that should not have happened has happened and our national interest is paramount and we have reported this position to the Ministry of Sports.” ((fa))Farsi language: ????????? ?????? ?? ????? ????????? ?????? ??? ? ????? ??? ?? ?? ?? ???? ?????? ???? ? ?? ??? ???? ?? ?? ????? ???? ?? ????? ?????.

IM Dorsa Derakhshani, who currently studies at Saint Louis University in the United States and plays for the United States Chess Federation, discussed her chess career, time in Iran and the 2017 controversy, and her life in Saint Louis with a Wikinews correspondent.

Train derailed by collision with semi in Saskatchewan, Canada

Tuesday, March 22, 2005

Twenty-four cars of a west-bound Canada Pacific train were thrown from the tracks after the train collided with a semi tractor-trailer in poor weather and visibility near Regina, Saskatchewan around 11 a.m. Tuesday morning. The driver was rushed to hospital.

The accident took place on a level section of Highway 46 just north of Highway 1, about 25 kilometres east of Regina. The RCMP spokesperson reported the crossing is marked with lights, but weather may have played a role.

“Road conditions were wet and sloppy and it’s foggy,” RCMP Cpl. Brian Jones said to the CBC. The bad weather, including a heavy overnight snowfall, may have contributed to the accident.

Most of the 93 cars in the train were empty bulk transit cars, used for moving agricultural products such as grains. The RCMP report that neither train or truck were transporting any hazardous materials.
