PREPARATION OF PAPERS FOR RESEARCH & DEVELOPMENT JOURNAL 1

1. INTRODUCCIÓN

Hoy en día la información corporativa se ha vuelto el punto clave para los fraudes dentro de las empresas o instituciones las cuales manejan gran cantidad de información confidencial de la cual depende su existencia y su crecimiento, por lo tanto, la seguridad y la tecnología deben ir de la mano para que las empresas puedan crecer de manera libre sin el temor a que su información sea sustraída por entes externos o internos a la institución, ya que a esta

información solo pueden acceder las personas autorizadas de la institución.

Por lo que el presente proyecto esta enfocado a la seguridad de los recursos internos de la red que maneja la Cooperativa de Ahorro y Crédito Escencia Indígena Ltda, por lo cual, se pretenderá implementar una distribución GNU/Linux LSBS, realizando un análisis de las diferentes distribuciones existentes en el mercado, dando como resultado una distribución que mas se ajuste a los requerimientos de la Cooperativa que posteriormente administrará de manera

Resumen: La seguridad de los recursos de internos de la red se ha vuelto uno de los pila- res fundamentales para que las entidades financieras que se mantienen el constante crecimiento, ya que si no existiese una seguridad de la información, cualquier ente externo podría acceder a la información importante para la misma; por esta razón las entidades financieras deben estar a la par de la tecnología a lo que a seguridad de la información se refiere, no solo para ser competitivas con otras similares sino por alcanzar los objetivos propuestos de la entidades mismas.

La implementación de este proyecto permitirá que la información que se encuentra internamente en la red sea más segura, compartiendo los recursos solo a los usuarios válidos que se encuentran registrados como empleados de la Cooperativa de Ahorro y Crédito Escencia Indígena Ltda, así tambien la instalación de Servidor Proxy http y Firewall que no permitirá el ingreso a páginas innecesarias para el trabajo diario.

Abstract: The security of internal resources of the network has become one of the funda- mental pillars for financial institutions remain steady growth, as if there were no security of information, any external body could access important information for the same; For this reason, financial institutions must keep pace with technology far as information security is concerned, not only to be competitive with other similar but to achieve the objectives of the

same entities. The implementation of this project will allow the information found internally in the network more secure, sharing resources only valid users who are registered as employees of the credit union Ltda Indian Essence, so Server installation HTTP Proxy and Firewall will not allow entry to unnecessary pages for daily work.

Keywords: LSBS, Proxy, Firewall, Gateway, Server, Internet.

correcta los recursos internos de la red.

1.2 Acerca de los Autores

As suggestion, it is important take in account that the first author is the researcher who that did most of the work, and probably he will put this into his thesis and will emphasize it in his cv, whereas the last author is typically the professor who obtained the grant, produced the intellectual lead and often edited and submitted the final draft of the paper.

2. PROCEDURE FOR PAPER SUBMISSION

2.1 Review Stage

Please use this document as a “template” to prepare your manuscript. For submission guidelines, follow instructions on paper submission system from CENI website. It will be better for you to prepare your initial submission in the camera ready layout so that you will have a good estimate for the paper length. Additionally, the effort required for final submission will be minimal.

2.2 Final Stage

Authors are expected to mind the margins diligently. Journal papers need to be stamped with journal data and paginated for inclusion in the proceedings. If your manuscript bleeds into margins, you will be required to resubmit and delay the proceedings preparation in the process.

2.3 Page margins

Your manuscript should be ‘camera-ready.’ Please do not modify margins. If you are creating a document on your own, please observe the margins as listed in Table 1. All dimensions are in centimeters.

Page Top Bottom Left/RightFirst 3.5 2.5 1.5Rest 2.5 2.5 1.5

Table 1. Page margins

It is very important to maintain these margins. They are necessary to put conference information and page number for the proceedings.

2.4 Figures and PDF Creation

All figures must be embedded in the document. When you include the image, make sure to insert the actual image rather than a link to your local computer. As far as possible, use standard PDF conversion tools Adobe Acrobat or Ghostscript give best results. It is important that all fonts be embedded/subsetted in the resulting PDF.

2.5 Copyright Form

Research & Development Journal will put in place an electronic copyright transfer system in due course. Please “do not” send copyright forms by mail or FAX. More information on this will be made available on CENI website.

3. MATH

If you are using Word, we suggest use either the Microsoft Equation Editor or the MathType add-on for equations in your paper (Insert | Object | Create New | Microsoft Equation or MathType Equation). “Float over text” should not be selected.

4. UNITS

Use either SI as primary units. Other units may be used as secondary units (in parentheses). This applies to papers in data storage. For example, write “15 Gb/cm2 (100 Gb/in2)”. Avoid combining SI and CGS units, such as current in amperes and magnetic field in oersteds. This often leads to confusion because equations do not balance dimensionally. If you must use mixed units, clearly state the units for each quantity in an equation.The SI unit for magnetic field strength H is A/m. However, if you wish to use units of T, either refers to magnetic flux density B or magnetic field strength symbolized as µ0H. Use the center dot to separate compound units, e.g. “A·m2”.

5. HELPFUL HINTS

5.1 Figures and Tables

Figure axis labels are often a source of confusion. Use words rather than symbols. As an example, write the quantity “Magnetization,” or “Magnetization M,” not just “M.” Put units in parentheses. Do not label axes only with units. For example, write “Magnetization (A/m)” or “Magnetization (A m1)”, not just “A/m.” Do not label axes with a ratio of quantities and units. For example, write “Temperature (K)”, not “Temperature/K”.

Multipliers can be especially confusing. Write “Magnetization (kA/m)” or “Magnetization (103 A/m)”. Do not write “Magnetization (A/m) 1000” because the reader would not know whether the top axis label meant 16000 A/m or 0.016 A/m. Figure labels should be legible, approximately 8 to 12 point type.

5.2 References

References must be cited in text. When there are number citations on the line, in square brackets inside the punctuation. Multiple references are each numbered with separate brackets. When citing a section in a book, please give the relevant page numbers. In text, refer simply to the reference number. Do not use “Ref.” or “reference” except at the beginning of a sentence: “Reference [3] shows ...”. Please do not use automatic endnotes in Word, rather, type the reference list at the end of the paper using the “References” style.Use standard style references (see at the end of this document). Footnotes should be avoided as far as possible.Please note that the references at the end of this document are in the preferred referencing style. Papers that have not been published should be cited as “unpublished.” Capitalize only the first word in a paper title, except for proper nouns and element symbols.

5.3 Abbreviations and Acronyms

Define abbreviations and acronyms the first time they are used in the text, even after they have already been defined in the abstract. Abbreviations such as UTA, SI, ac, and dc do not have to be defined. Abbreviations that incorporate periods should not have spaces: write “C.N.R.S.”, not “C. N. R. S.” Do not use abbreviations in the title unless they are unavoidable.

5.4 Equations

Number equations consecutively with equation numbers in parentheses flush with the right margin, as in (1). First use the equation editor to create the equation. Then select the “Equation” mark-up style. Press the tab key and write the equation number in parentheses. To make your equations more compact, you may use the solidus ( / ), the exp function, or appropriate exponents. Use parentheses to avoid ambiguities in denominators. Punctuate equations when they are part of a sentence, as in

(1)

Be sure that the symbols in your equation have been defined before the equation appears or immediately following. Italicize symbols (T might refer to temperature, but T is the unit tesla). Refer to “(1)”, not “Eq. (1)” or “equation (1)”, except at the beginning of a sentence: “Equation (1) is …”

5.5 Other Recommendations

Use one space after periods and colons. Hyphenate complex modifiers: “zero-field-cooled magnetization.” Avoid dangling participles, such as, “Using (1), the potential was calculated.” [It is not clear who or what used (1).] Write instead, “The potential was calculated by using (1),” or “Using (1), we calculated the potential.”Use a zero before decimal points: “0.25,” not “.25.” Use “cm3,” not “cc.” Indicate sample dimensions as “0.1 cm 0.2 cm,” not “0.1 0.2 cm2”. The abbreviation for “seconds” is “s”, not “sec”. Use “Wb/m2” or “webers per square meter,” not “webers/m2.” When expressing a range of values, write “7 to 9” or “7-9”, not “7~9”.A parenthetical statement at the end of a sentence is punctuated outside of the closing parenthesis (like this). (A parenthetical sentence is punctuated within the parentheses.) Avoid contractions; for example, write “do not” instead of “don’t”. The serial comma is preferred: “A, B, and C” instead of “A, B and C”.

6. CONCLUSIONS

A conclusion section is not required. Although a conclusion may review the main points of the paper, do not replicate the abstract as the conclusion. A conclusion might elaborate on the importance of the work or suggest applications and extensions.

7. ACKNOWLEDGMENT (OPTIONAL)

The preferred spelling of the word “acknowledgment” in American English is without an “e” after the “g.” Use the singular heading even if you have many acknowledgments. Avoid expressions such as “One of us (S.B.A.) would like to thank ...”. Instead, write “F. A. Author thanks ...”. In most cases, sponsor and financial support acknowledgments are placed in the unnumbered footnote on the first page, not here.

REFERENCES

List of references arranged alphabetically according to first author, subsequent lines indented. Do not number references. Publications by the same author(s) should be listed in order of year of publication. If there is more than one paper by the same author(s) and with the same date, label them a, b, etc., e.g. Morris et al. (1990a, b). Please note that all references listed here must be directly cited in the body of the text by using [].
