A. DEFINITION

A business letter is a formal communication from an organization to its customers, the general public for their information, another Company or the Authorities. It is often written in a standard format, and in formal language, compared to a private letter between two people who are well known to each other. The business letter will show things like the address and best way to communicate with the business – by return letter , e-mail or telephone. In general, the letter will be directed to a specific person and be about one topic. Sometimes, the business letter will be looking for a response, but might be to give important information about an up-coming change of address or telephone number. The letter might give information about new developments – a new website; launch of a new product. To allow the sender to handle any response more efficiently, the business letter might contain key information such as an internal reference from the sender or related to the product in question.

A written commitment to pay, by a buyer’s or importer’s bank (called the issuing bank) to the seller’s or exporter’s bank (called the accepting bank, negotiating bank, or paying bank). A letter of credit guarantees payment of a specified sum in a specified currency, provided the seller meets precisely-defined conditions and submits the prescribed documents within a fixed timeframe. These documents almost always include a clean bill of lading or air waybill, commercial invoice, and certificate of origin.

To establish a letter of credit in favor of the seller or exporter (called the beneficiary) the buyer (called the applicant or account party) either pays the specified sum (plus service charges) up front to the issuing bank, or negotiates credit. Letters of credit are formal trade instruments and are used usually where the seller is unwilling to extend credit to the buyer. In effect, a letter of credit substitutes the creditworthiness of a bank for the creditworthiness of the buyer. Thus, the international banking system acts as an intermediary between far flung exporters and importers. However, the banking system does not take on any responsibility for the quality of goods, genuineness of documents, or any other provision in the contract of sale.

Since the unambiguity of the terminology used in writing a letter of credit is of vital importance, the International Chamber Of Commerce (ICC) has suggested specific terms (called Incoterms) that are now almost universally accepted and used. Unlike a bill of exchange, a letter of credit is a nonnegotiable instrument but may be transferable with the consent of the applicant. Although letters of credit come in numerous types, the two most basic ones are (1) Revocable-credit letter of credit and (2) Irrevocable-credit letter of credit, which comes in two versions (a) Confirmed irrevocable letter of credit and (b) Not-confirmed irrevocable letter of credit.

B. Types of Business Letters
The most important element you need to ensure in any business letter is accuracy. One of the aspects of writing a business letter that requires the most accuracy is knowing which type of business letter you are writing. A number of options are available for those looking to trade in business correspondence, and you will significantly increase your odds for getting a reply if you know the form you need to send.

  1. Letter of Complaint

A letter of complaint will almost certainly result in an official response if you approach it from a businesslike perspective. Make the complaint brief, to the point and polite. Politeness pays off regardless of the extent of anger you are actually feeling while composing this type of business letter.

2. Resume Cover Letter

A cover letter that accompanies a resume should revel in its brevity. You should take as little time and as few words as possible to accomplish one task: persuading the reader to anticipate reading your resume. Mention the title of the job for which you are applying, as well or one or two of your strongest selling points.
3. Letter of Recommendation

A recommendation letter allows you to use a few well-chosen words to the effect of letting someone else know how highly you value a third party. Resist the temptation to go overboard; approach your recommendation in a straightforward manner that still allows you to get the point across.
4. Letter of Resignation
An official letter of resignation is a business letter that should be fair and tactful. Be wary of burning any bridges that you may need to cross again in the future. Offer a valid reason for your resignation and avoid self-praise.
5. Job Applicant Not Hired
In some cases you may be required to write a business letter that informs a job applicant that he was not chosen for an open position. Offer an opening note of thanks for his time, compliment him on his experience or education and explain that he was just not what the company is looking for at the present time.
6. Declining Dinner Invitation
Declining a dinner invitation is a topic for a business letter that, if not done tactfully, may result in a social disadvantage. Extend your appreciation for the invitation and mention that you already have an engagement for that date. Do not go into detail about what the engagement is.
7. Reception of Gift
It is very polite to return a formal business response letting someone know that you have received her gift. Extend a personalized thanks to let her know that you are exactly aware of the contents of the gift. If possible, it is a good idea to include a sentiment suggesting that you have put the gift to use.
8. Notification of Error
When sending a business letter that lets the receiving party know that an error has been corrected, it is good business sense to include a copy of the error in question if there is paperwork evidence of it. Make the offer of additional copies of material involved in the error if necessary.
9. Thanks for Job Recommendation
A letter of thanks for a party that helped you get a job should be professional and courteous. Above all else, avoid the temptation to go overboard in offering your thanks. Be aware that your skills also helped you land the job and it was likely not handed to you as a result of the third party.
10. Information Request
A business letter that requests information should make the request specific and perfectly understandable. It is also a good idea to state the reason for the information request. Extend advance appreciation for the expected cooperation of the recipient.

C. Parts of Business Letters

A business letter is more formal than a personal letter. It should have a margin of at least one inch on all four edges. It is always written on 8½”x11″ (or metric equivalent) unlined stationery. There are six parts to a business letter.

  • The Heading (The Retern Address) or Letterhead – Companies usually use printed paper where heading or letterhead is specially designed at the top of the sheet. It bears all the necessary information about the organisation’s identity.
  • Date – Date of writing. The month should be fully spelled out and the year written with all four digits October 12, 2005
    (12 October 2005 – UK style). The date is aligned with the return address. The number of the date is pronounced as an ordinal figure, though the endings st, nd, rd, th, are often omitted in writing. The article before the number of the day is pronounced but not written. In the body of the letter, however, the article is written when the name of the month is not mentioned with the day.
  • The Inside Address – In a business or formal letter you should give the address of the recipient after your own address. Include the recipient’s name, company, address and postal code. Add job title if appropriate. Separate the recipient’s name and title with a comma. Double check that you have the correct spelling of the recipient ‘s name.
    The Inside Address is always on the left margin. If an 8 1/2″ x 11″ paper is folded in thirds to fit in a standard 9″ business envelope, the inside address can appear through the window in the envelope.
  • The Greeting – Also called the salutation. The type of salutation depends on your relationship with the recipient. It normally begins with the word “Dear” and always includes the person’s last name. Use every resource possible to address your letter to an actual person. If you do not know the name or the sex of of your reciever address it to Dear Madam/Sir (or Dear Sales Manager or Dear Human Resources Director). As a general rule the greeting in a business letter ends in a colon (US style). It is also acceptable to use a comma (UK style).
  • The Subject Line (optional) – Its inclusion can help the recipient in dealing successfully with the aims of your letter. Normally the subject sentence is preceded with the word Subject: or Re: Subject line may be emphasized by underlining, using bold font, or all captial letters. It is usually placed one line below the greeting but alternatively can be located directly after the “inside address,” before the “greeting.”
  • The Body Paragraphs – The body is where you explain why you’re writing. It’s the main part of the business letter. Make sure the receiver knows who you are and why you are writing but try to avoid starting with “I”. Use a new paragraph when you wish to introduce a new idea or element into your letter. Depending on the letter style you choose, paragraphs may be indented. Regardless of format, skip a line between paragraphs.
  • The Complimentary Close – This short, polite closing ends always with a comma. It is either at the left margin or its left edge is in the center, depending on the Business Letter Style that you use. It begins at the same column the heading does. The traditional rule of etiquette in Britain is that a formal letter starting “Dear Sir or Madam” must end “Yours faithfully”, while a letter starting “Dear ” must end “Yours sincerely”. (Note: the second word of the closing is NOT capitalized)
  • Signature and Writer’s identification – The signature is the last part of the letter. You should sign your first and last names. The signature line may include a second line for a title, if appropriate. The signature should start directly above the first letter of the signature line in the space between the close and the signature line. Use blue or black ink.
  • Initials, Enclosures, Copies – Initials are to be included if someone other than the writer types the letter. If you include other material in the letter, put ‘Enclosure’, ‘Enc.’, or ‘ Encs. ‘, as appropriate, two lines below the last entry. cc means a copy or copies are sent to someone else.

KEAMANAN KOMPUTER

Filed under: Uncategorized — evynathyna @ 7:26 am

Pengertian Keamanan Komputer

  • Menurut John D. Howard dalam bukunya “An Analysis of security incidents on the internet” menyatakan bahwa :
  • Keamanan komputer adalah tindakan pencegahan dari serangan pengguna komputer atau pengakses jaringan yang tidak bertanggung jawab.
  • Menurut Gollmann pada tahun 1999 dalam bukunya “Computer Security” menyatakan bahwa:

Keamanan komputer adalah berhubungan dengan pencegahan diri dan deteksi terhadap tindakan pengganggu yang tidak dikenali dalam system komputer.

Dalam keamanan sistem komputer yang perlu kita lakukan adalah untuk mempersulit orang lain untuk mengganggu sistem yang kita pakai, baik itu kita menggunakan komputer yang sifatnya stand alone, jaringan local maupun jaringan global. Kita harus memastikan system bisa berjalan dengan baik dan kondusif, selain itu program aplikasinya masih bisa dipakai tanpa ada masalah.

>> Beberapa hal yang menjadikan kejahatan komputer terus terjadi dan cenderung meningkat adalah sebagai berikut :

  • Meningkatnya pengguna komputer dan internet
  • Banyaknya software yang pada awalnya digunakan untuk melakukan audit sebuah system dengan cara mencari kelemahan dan celah yang mungkin ada disalahgunakan untuk melakukan scanning system orang lain.
  • Banyaknya software-software untuk melakukan probe dan penyusupan yang tersedia di Internet dan bisa di download secara gratis.
  • Meningkatnya kemampuan pengguna komputer dan internet
  • Desentralisasi server sehingga lebih banyak system yang harus ditangani, sementara SDM terbatas.
  • Kurangnya huku yang mengatur kejahatan komputer.
  • Semakin banyaknya perusahaan yang menghubungkan jaringan LAN mereka ke Internet.
  • Meningkatnya aplikasi bisnis yang menggunakan internet.
  • Banyaknya software yang mempunyai kelemahan (bugs).

>> Ada beberapa hal yang bisa menjawab pertanyaan mengapa kita perlu mengamankan sistem komputer, antara lain :

  • Menghindari resiko penyusupan, kita harus memastikan bahwa system tidak kemasukaan penyusup yang bisa membaca, menulis dan menjalankan program-program yang bisa mengganggu atau menghancurkan system kita.
  • Mengurangi resiko ancaman, hal ini biasa berlaku di institusi dan perusahaan swasta. Ada beberapa macam penyusup yang bisa menyerang system yang kita miliki.
  • Melindungi system dari kerentanan, keretanan akan menjadikan system kita berpotensi untuk memberikan akses yang tidak diizinkan bagi orang lain yang tidak berhak.
  • Melindungi system dari gangguan alam seperti petir dan lain-lainnya.

Melihat dari point-point di atas, sebenarnya kenapa kita perlu menjaga keamanan komputer adalah untuk menjaga informasi, karena informasi sudah menjadi komoditi yang sangat penting. Bahkan ada yang mengatakan bahwa kita sudah berada disebuah “Information based society”. Kemampuan untuk mengakses dan menyediakan informasi secara cepat dan akurat menjadi sangat esensial bagi sebuah organisasi, baik yang berupa organisasi komersial (perusahaan), perguruan tinggi, lembaga pemerintahan, maupun individual.

>> Aspek-aspek keamanan komputer :
Inti dari keamanan komputer adalah melindungi komputer dan jaringannya dengan tujuan mengamankan informasi yang berada di dalamnya. Keamanan komputer sendiri meliputi beberapa aspek , antara lain :

  • Privacy, adalah sesuatu yang bersifat rahasia (private). Intinya adalah pencegahan agar informasi tersebut tidak diakses oleh orang yang tidak berhak. Contohnya adalah email atau file-file lain yang tidak boleh dibaca orang lain meskipun oleh administrator. Pencegahan yang mungkin dilakukan adalah dengan menggunakan teknologi enksripsi, jadi hanya pemilik informasi yang dapat mengetahui informasi yang sesungguhnya.

Confidentiality, merupakan data yang diberikan ke pihak lain untuk tujuan khusus tetapi tetap dijaga penyebarannya. Contohnya data yang bersifat pribadi seperti : nama, alamat, no ktp, telpon dan sebagainya. Confidentiality akan terlihat apabila diminta untuk membuktikan kejahatan seseorang, apakah pemegang informasi akan memberikan infomasinya kepada orang yang memintanya atau menjaga klientnya.

  • Integrity, penekanannya adalah sebuah informasi tidak boleh diubah kecuali oleh pemilik informasi. Terkadang data yang telah terenskripsipun tidak terjaga integritasnya karena ada kemungkinan chpertext dari enkripsi tersebut berubah. Contoh : Penyerangan Integritas ketika sebuah email dikirimkan ditengah jalan disadap dan diganti isinya, sehingga email yang sampai ketujuan sudah berubah.
  • Autentication, ini akan dilakukan sewaktu user login dengan menggunakan nama user dan passwordnya, apakah cocok atau tidak, jika cocok diterima dan tidak akan ditolak. Ini biasanya berhubungan dengan hak akses seseorang, apakah dia pengakses yang sah atau tidak.
  • Availability, aspek ini berkaitan dengan apakah sebuah data tersedia saat dibutuhkan/diperlukan. Apabila sebuah data atau informasi terlalu ketat pengamanannya akan menyulitkan dalam akses data tersebut. Disamping itu akses yang lambat juga menghambat terpenuhnya aspe availability. Serangan yang sering dilakukan pada aspek ini adalah denial of service (DoS), yaitu penggagalan service sewaktu adanya permintaan data sehingga komputer tidak bisa melayaninya. Contoh lain dari denial of service ini adalah mengirimkan request yang berlebihan sehingga menyebabkan komputer tidak bisa lagi menampung beban tersebut dan akhirnya komputer down.
