Tips For Safe Computing - to Small Business

2009-01-18T16:07:00.000+07:00

Ensure you have the latest updates
Install updates and security patches on all servers, desktop and laptop PCs.
• To get the latest updates for your Windows operating system, software and hardware, go to Microsoft Update (U.S.). It scans your computer to determine which updates you need and then you can download any or all of them.
• To improve the security and stability of your Microsoft Office software, go to Office Update (U.S.) and follow the Check for Updates link.
If you use Windows XP Professional, there is an even easier way to get updates. Simply activate the Automatic Updates feature, which allows your PC to automatically notify you of important updates once they are made available.

Reduce the risk of viruses
There are numerous things you can do to protect your computer and your network against viruses. Using anti-virus software and keeping it current is the first step, but there are other things you can do:
• Use the default security settings in Office 2003, which is the most secure version of Office released to date
• Visit the Office Update (U.S.) site for the latest updates and patches
• Never open suspicious e-mail messages or file attachments; take advantage of the state-of-the-art junk mail filter in Outlook 2003 to send suspicious messages directly to your Junk E-mail Folder
Use Windows Security Centre to manage your settings
Get a clear picture of the security settings on your PC using the single, unified view provided in the Windows Security Centre. Adjust them as necessary to the level of protection you are comfortable with. The settings that guard your PC are automatically applied to files and content delivered via the internet, helping safeguard confidential business data.

Encrypt sensitive information on your laptop
If you travel on business and use a laptop that runs Windows 2000 Professional or Windows XP Professional, guard against data theft. Use the Encrypted File System (EFS) to encrypt sensitive files and folders. If the laptop is stolen, your files and folders are protected because only those with a special decryption key can access the encrypted files.

Download internet files from trusted sources only
If you're unsure if the files you want to download are safe, consider downloading them to a disk separate from your hard drive, such as a CD or floppy. Then you can scan the files with your virus scanner.

Use password encryption to protect Office files
Improved encryption technology has strengthened password security in Word 2003 and Excel 2003 and extends password encryption to PowerPoint 2003. Look under the Tools menu in each of these three programs to activate password protection. This is an effective way to restrict access to confidential business information.

Clean your hard drive before you discard a PC
If you're getting a new PC or notebook and your old one is being discarded, be sure to remove any sensitive business or personal information before you let it go. This doesn't mean simply deleting files and emptying your Recycle Bin. Your options include reformatting the hard drive or acquiring software that wipes it clean.

Use a firewall
If your company uses always-on broadband to connect to the internet, install a firewall as a basic line of defence against outside intruders. There are two basic types: 1) a software firewall such as the Microsoft Internet Connection Firewall that's included in Windows XP Professional protects the machine it runs on, and 2) a hardware firewall that blocks all traffic between the internet and your entire network except for traffic from senders who are specifically trusted.

Never surf the web from a server
As the command centre for your entire network, a server typically stores critical business information. If your server is compromised, it puts all of that data as well as your entire network at risk.

Be smart about passwords
Always use strong passwords that are at least eight characters long and a combination of lower and upper case letters, numbers and symbols. Don't use the same password repeatedly and make it a point to change your passwords frequently. If you have trouble remembering passwords, consider using a pass-phrase, which you can do in Windows 2000 and Windows XP. A pass-phrase might be something like "I had pizza for lunch Tuesday."

the Computer Become Slowed down

2009-01-17T16:01:00.000+07:00

I have been attending to a whole host of computer users recently who have been wondering why their computer has got so slow.

There are, of course, many reasons why a computer slows down but an extremely common reason these days is the fact that your computer simply doesn’t have the resources to cope with the modern world any more.
A great example of something that suffers under the pressure of resource hungry programs mean is RAM – Random Access Memory – Having adequate RAM is essential to a speedy computer. Without enough your computer will grind to a halt and all you will hear is the whirring of the hard disk every time you move you mouse – sound familiar?

People often think that if their computer ran ok when it was bought then it should still be capable of running the same speed now. This is true to a degree but only if you strip back any software you may be using back to the same software you used on day one.

I am shocked to visit people who are running Windows XP with only 256mb of RAM. Computer suppliers were selling cheap computers with this minimal amount of RAM right up to about 3 years ago. With just Windows XP on and nothing more running the computer would be sluggish, install all the updates – especially service pack 3 (This will install by default if you have automatic updates on) and your computer will grind to a halt.

Another huge change that has occurred since the days XP could run ok with 256mb of RAM is internet security. With firewalls, antivirus and adware/spyware programs running resources are quickly consumed. These programs have accelerated in size over the last few years with all the new threats the internet brings. These have become very resource hungry.

The point I am trying to get at is that you need to ensure that your computer has enough RAM – 512mb is just about acceptable but will struggle. I normally recommend 1gb minimum for XP and 2gb minimum for Vista.

If you are unsure how much RAM you have then you can check by looking at your system properties and here is a handy shortcut to get there – within windows press and hold the windows key on your keyboard followed by the pause button.

If you find that you need more RAM it is generally a simple procedure to change and at the moment RAM is pretty cheap so get in there quickly!

Tips on Laptop Repair

2009-01-16T15:57:00.000+07:00

Laptops are complicated pieces of equipment but repairing one may not be as expensive as a laptop repair technician may lead you to believe. It is important to carry out thorough research before embarking on a laptop yourself. Ensure that you have a few basic items to assist you rather than making the common mistake of grabbing anything nearby. A Laptop is not an inexpensive item to replace so it is worth avoiding unnecessary mistakes.

This article is intended as a rough guide of tips for laptop repair, there is plenty of information out there on the internet that will help with specific enquiries. Make sure you ask all the questions before you begin to attempt a repair yourself, if you don’t do the research you may be charged more for someone to correct the mistakes that you have made. Should you decide to undertake a repair be sure that you have a good understanding of what needs to be done, if you don’t have the first idea seek professional help.

Before you begin it is sensible to make sure you have long nosed tweezers, an electric static discharge mat, a Teflon wedge, needle nose pliers and Phillips head screwdrivers size 0 & 1. Take a back-up of everything on the hard drive before beginning the repair, just in case. It is best if possible for the repair to take place in a room without carpet.

One word of advice if you are playing around with the LCD the backlight inverter can give you quite a nasty shock if the laptop is powered up. So ensure that the laptop is switched off and unplugged from the mains. It is also sensible to remove the laptops battery and hard drive before beginning a repair.

Obviously if you are a novice to laptop repair you will probably not own anti-static gear like wrist straps etc, if there is a likelihood of you carrying out laptop repairs regularly it may be worth investing in the anti-static gear, rather than killing off your laptop and having to dump it in the rubbish.

When carrying out a repair do not disassemble the laptop unless it is necessary to do so. Try to ensure the environment you are to work in is clean and make sure that you have the correct tools. Before beginning the repair make sure that you test the machine properly, you need to have the correct symptoms to diagnose the fault. If you need to remove any parts of the laptop take care to keep the parts in a safe place where they won’t get damaged. When removing screws keep them with each part they have been taken from, this will help when reassembling the laptop. When fitting the laptop back together use the correct size screws for each part, this will prevent you ending up with screws that simply do not fit the holes you are left with. Before disconnecting connectors make sure that you have had a good look at how they work, it is worth making notes for yourself as you carry out the repair as it will help jog your memory.

Resiko Keamanan Komputer

2008-12-01T13:06:00.001+07:00

Resiko keamanan komputer (Computer Security Risk) merupakan setiap peristiwa yang dapat mengakibatkan hilang atau rusaknya peranti keras, peranti lunak, data, informasi, atau kemampuan memproses komputer. Sebagain pelanggaran terhadap keamanan komputer tidak disengaja. Akan tetapi ada juga pelanggaran yang memang sudah direncanakan.

Pelanggaran keamanan komputer yang disengaja sering kali melibatkan tindakan yang melanggar hokum. Setiap tindakan illegal yang melibatkan komputer secara umum dikenal dengan istilah “Kejahatan Komputer (computer Crime)” .

Istilah “Cybercrime (Kejahatan didunia cyber)” mengacu pada tindakan illegal / Kejahatan komputer melalui Jaringan Internet dimana tindak pidana terjadi diluar dunia nyata yaitu dunia maya. Saat ini cybercrime termasuk dalam tiga besar prioritas FBI.

Para pelaku cybercrime dan gangguan – gangguan lainnya dibagi menjadi 3 kategori dasar, yaitu Hacker, Cracker, Script Kiddie, Mata – mata Perusahaan, Karyawan tidak beretika, Cyberextortionist, dan Cyberterrorost.

Adware and spyware, knowing the basics

2008-11-27T12:00:00.000+07:00

People think that there is actually no difference between a spyware and an adware. Spyware is just a web term used to refer to an advertising supported software, which is otherwise known as adware. These are the pop-up ads that often come out whenever we open a website or download a shareware software. But according to some web experts, spyware is much much more.

Supporters of spyware and adware say that though it can be pretty annoying at times especially if you are really in a hurry, both do give consumers huge benefits. Because the product ads generate income for developers of shareware software, consumers can get them for free. Developers are in turn paid for their work. Of course, if you don't want to be bothered by the constant pop-ups, you can always pay the licensing fee or the regular fee for the software. If you want it for free, you just have to sacrifice through the spyware.

There is however another downside to it. Spyware, from the name given to it, is actually used as a tracking device in your computer system. These tracking devices will look into your surfing habits, your chatting logs and even the number of times you open your email. If designed or programmed the right way, it can discover just about everything else in your system. And because the program runs in the background, there is no way that a person can control the kind of information that he or she sends out.

These kinds of programs were actually originally used by parents or people in the business sector who wish to track down and put on record web activity. It is actually beneficial but not when people are not aware that they are being tracked down. This is often the case when people download software over the Internet. As mentioned before, it is used by companies to advertise their products and in turn help the developers of software keep their costs down so that they can afford to offer their programs for free.

Although privacy issues indeed come into play, there is nothing illegal about it. In fact, its use is prevalent all over the World Wide Web. There are however some areas that people who value their privacy will object to. Because of this, people are given the option to refuse the software.

There is really no way that one can avoid adware and spyware as these programs are packaged with the software that you will be downloading from the Internet. The most that you can do is to avoid downloading from the internet and to refuse any file downloads that you did not personally authorize. It is also good to only view websites that have a good reputation or those that have anti-spyware and adware programs installed in their pages.

A Simple E-mail Server

2008-11-20T15:40:00.000+07:00

Given that you have an e-mail client on your machine, you are ready to send and receive e-mail. All that you need is an e-mail server for the client to connect to. Let's imagine what the simplest possible e-mail server would look like in order to get a basic understanding of the process. Then we will look at the real thing.

If you've read How Web Servers Work, then you know that machines on the Internet can run software applications that act as servers. There are Web servers, FTP servers, telnet servers and e-mail servers running on millions of machines on the Internet right now. These applications run all the time on the server machine and they listen to specific ports, waiting for people or programs to attach to the port. The simplest possible e-mail server would work something like this:

It would have a list of e-mail accounts, with one account for each person who can receive e-mail on the server. My account name might be mbrain, John Smith's might be jsmith, and so on.
It would have a text file for each account in the list. So, the server would have a text file in its directory named MBRAIN.TXT, another named JSMITH.TXT, and so on.
If someone wanted to send me a message, the person would compose a text message ("Marshall, Can we have lunch Monday? John") in an e-mail client, and indicate that the message should go to mbrain. When the person presses the Send button, the e-mail client would connect to the e-mail server and pass to the server the name of the recipient (mbrain), the name of the sender (jsmith) and the body of the message.
The server would format those pieces of information and append them to the bottom of the MBRAIN.TXT file. The entry in the file might look like this:

From: Radith

To: mbrain

Marshall,

Can we have dinner Monday?

John

There are several other pieces of information that the server might save into the file, like the time and date of receipt and a subject line; but overall, you can see that this is an extremely simple process.

Why the Need For Vitamin A

2008-11-20T15:22:00.000+07:00

Vitamin A is an essential fat-soluble vitamin which promotes our eyesight and helps us see in the dark. It also aids in the differentiation of cells of the skin (lining the outside of the body) and mucous membranes (linings inside of the body). Vitamin A is important as it helps the body fight off infection and sustain the immune system, but it also supports growth and remodeling of bone.

If you body doesn't receive the needed vitamin A, then you could become vitamin A-deficient, which can lead to night blindness, bone problems, reduced immune system and health, anemia and unhealthy skin.

How much vitamin A is needed?
The Recommended Dietary Allowance (RDA) for vitamin A is measured in retinol equivalents (RE), retinol being the active form of vitamin A.

For men - 1000 micrograms of RE per day
For women - 800 micrograms of RE per day

Where to get Vitamin A from?
Most people would first reach for their vitamin supplements, but the best way to get your vitamins is from your diet.

Richest Sources of Vitamin A:

liver,
fish
liver oils,
milk,
milk products,
butter,
eggs.

Other Sources of Vitamin A:

A variety of dark green and deep orange fruits and vegetables -
carrots,
sweet potatoes,
pumpkin,
spinach,
butternut squash,
turnip greens,
bok choy,
mustard greens,
lettuce.

One thing to keep in mind - the absorption of vitamin A from the diet is improved when consumed along with some fat in the same meal.
