Why do we need cyber security? There a number of reasons. The cyber community changes in an unbelievable pace. Unfortunately, along with these changes are equally unbelievable threats. The nature of the Internet as a tool for communication and education has been used and misused for personal gain, which resulted in cyber attacks and unprecedented rise in cyber crime rates. These rates are expected to increase more rapidly in the coming years if cyber security is not put in place. So, why exactly do we need cyber security? Let us count the reasons.

1.) Hackers are everywhere. He can be your business rival, your neighbor, or simply a person out to take over your computer. He makes use of software loopholes and hijacks your computer through backdoors, usually installed programs, or through cracking software. When he finally marches into your computer, he can gain access to possibly all your personal and confidential information such as bank accounts, credit cards, or top trade secret. He can also use your computer to attack other networks, with you apparently oblivious to all his malicious operations.

2.) Internet scams and frauds are rampant. These include phishing, a very organized cyber crime, which deceives people into giving their banking details. Cyber criminals, pretending to be representatives from legitimate financial institutions, send e-mail messages and ask unsuspecting people to verify their passwords, account numbers, and other vital information. According to a report, in 2006 alone, phishing attempts increased by 81%. These attempts could effectively be counterattacked if they weren’t too sophisticated to actually deaden spam filters.

3.) Cyber theft is a common cyber crime. In fact, it is the most reported. Over time, it has increasingly become so easy for cyber criminals to steal information from computers, not only from individuals but for companies, banks, and other organizations as well. Though they hardly report the case, big companies lose large amounts of money.

4.) Virus can slow down your computer. Worse, it can cause system crash. Virus reaches your system through a number of entryways. One is through unsecured and unknown websites from which you download files, programs, applications, or tools for free. As much as it can infect home computers, virus can leave damaging effects to companies, both big and small. For instance, Melissa virus hit Microsoft and other big companies in 1999, which led them to temporarily terminate their e-mail systems.

5.) Spyware, as the name hints, can spy on you. A computer program automatically installed on your computer, spyware tracks personal information you entered and sends it to its creator. In most cases, spyware is used to steal big sum of money. Unlike computer viruses, spyware leaves the computer owners totally unaware of its presence. A study revealed that 92% of users with infected systems don’t know that spyware has broken into their computers.

6.) Adware can keep unwanted ads to show up. Like spyware, adware penetrates the system through shareware. On its own, it downloads ads and allows them to run and pop up. This proves to be quite annoying for computer owners. But what’s even more troubling is that adware can sometimes contain spyware. This increases the risk for cyber threats.

Why do we need cyber security? Cyber criminals are smart beings. They find ways to get into our systems and create havoc in less time than we expect. And because they don’t cease to innovate and produce more sophisticated threats, we should always put our guard on and reinforce whatever cyber security measures we have these days.

$Consider the printer’s DPI (dots per inch) capability, which is the resolution at which it can print photos and documents. The higher DPI (dots per inch) you have, the better quality you will have in either text or photo printouts.

$Consider the cost of ink. When purchasing a new printer, take a moment to compare prices among ink cartridges and make sure that you can afford frequent ink purchases if you plan to do a lot of printing.

$Take a look at the connector and make sure it’s compatible with your system. Most new printers connect via a USB port. Older ones connect using a parallel port, which is not commonly found on new PCs.

$When looking at the cost of ink, also look at the number of pages a single ink cartridge can print. If the page count is high, the cost of the ink may be reasonable. If the page count is low compared to other similar ink cartridges, you may want to select another printer that offers a better performing ink cartridge.

$Check out the warranty. All new electronics, including printers, carry a manufacturer’s warranty. Depending on the company, warranties can be valid anywhere from 90 days to 1 year and may include defects in material and/or workmanship. If your printer fails to perform correctly and develops a problem while under warranty, you will be glad that you saved the paperwork. Always keep the original purchase receipt and warranty information relating to your purchase.

$Buy from a name that you trust. When shopping for any item, it is best to purchase from a manufacturer that you know produces a quality product and especially when it comes to a substantial electronics purchase.

$Consider the size and weight of the printer. This is important for both cleaning general convenience. If your desk is small, you may not want a bulky printer taking up most of your space. At the same time, you may not want to lift on a heavy piece of equipment when cleaning your work station. A lightweight and compact style may be better, especially if your office is at home.

$Make sure that your computer is capable of running the printer software, which means it may require a specific processor type and speed, available memory, etc.

$Make sure that the printer you purchase has all of the features and capabilities that you need. For instance, if your primary goal is to produce realistic photos and you also plan to print written documents from time to time, consider the purchase of a photo printer. You can change the quality of printing to suit either images or documents or even a combination of both if you plan to print photo newsletters.

$Make sure that the printer has all of the necessary connector cables and that you will not need to buy any additional hardware prior to finalizing your purchase. If you need to purchase a USB cable, which is often the case with many new printers, you will want to purchase it at the same time to save on shipping if ordering online or having to make a special trip if you purchase locally.

You turn on your computer and you’re prompt with a username and password. The same thing happens when you open your email account. I know it is quite obvious to you right now but allow me to stress the importance of cyber security by having password protected files, networks, and software applications. It is important to protect your personal information. Sure, it seems unimportant if people hacked into your email account.

You have a bunch of personal emails from friends and occasionally send some your self but the whole lot of your mails in your inbox are spam and other promotional garbage, so why do you have to care that much. But the thing is, those who are able to gain access to your email accounts are often not truly satisfied with that level of attach and are in reality just preparing for a much bigger intrusion.

Before you know it, they can get information about your social security number of even bank accounts. Your personal emails contain heaps of information which can be used by hackers for their own personal gain.

Having a good password installed is therefore a good deterrent for hackers or attackers. It ensures that proper authentication is verified first before you gain access to personal information. It is therefore important that you make up a good password. A poorly made one will just be ineffective and totally useless against hackers.

For instance, using part of your name as a password would be just too easy to crack. It will not be a deterrent at all. To add to this, there are applications like virus and worms that can actually penetrate a secure or confidential system just because it has a weak password installed.

Example of weak passwords, aside from a derivative from your name, would be using numbers that coincides with birthdays, phone numbers, addresses and information about your family or stuff. Sure, these are easy to remember but that thinking will also cause you problems later on. These kinds of numeric passwords are just easy to solve. The same thing goes with dictionary based passwords which are those words that you picked up from a dictionary.

Now in making up your password, it would be a lot better if you use combinations of letter, numbers and other techniques. You could intentionally misspell the words so you won’t fall for dictionary attackers. You can add numbers and a combination of upper and lower cases. Or you could assign a code.

You can abbreviate something that if you love “watching soap shows on TV” you can take the first letters of the word “WsSoT” and combine it with a relevant numbers. Not only would the acronym easy to remember but it would be difficult for hackers to crack. However, avoid using famous quotes, catch phrases, lyrics, poem and even pick up lines. Go for something you invented.

Also, remember that having a longer password is better. The more characters you have the harder it is to guess or the more difficult to decipher the combinations. Also, don’t use the same password twice for your other accounts. Although this is quite tempting since you don’t have to create a new one and remember it every time, when an attacker does get a password from one of your accounts, the first thing he will do is to try the same password for all your other accounts.

Cyber security begins with you. Keeping your personal information safe lies first on password protected access to your files, systems and networks. Having a right and strong password will help fight off attackers.

Thermomechanical properties of a thermal roll sleeve with a copper alloy are obtained by a uniaxial tensile test for variation of temperature. The proposed analysis techniques have improved in caster roll design.
Thermal Roll
The thermal rolls of print media of this invention comprise a core/spindle and a sheet, preferably continuous, of a print medium of substantially the same width as the core/spindle. The sheet of print medium is wound around the core/spindle to provide a thickness of layered paper on the core/spindle of at least one half inch, measured from the periphery of the core/spindle to the outer layer of the sheet of print medium on the roll. At least one side of the wound sheet of print medium is marked with at least one impression which serves as an identifying mark. The “sides” of the roll of a print medium, as referred to herein, are where the edges of the wound print medium are exposed. The term “impression” as used herein includes shallow indentations as well as realignment of the edges of the wound print medium and realignment of the fibers within the wound print medium. In realigning the edges and/or fibers of the wound print medium, there may be no indentation which is detectable and in certain embodiments, no indentation at all.

Thermal paper rolls in the past is no longer true. While thermal tape used to be an uncommon alternative due to a short lifespan and high prices, it’s now the most viable choice. Recent developments have led to better technology, including advanced chemical films and more durable substrata.

The rolling force and roll deformation behavior in the twin-roll-type strip continuous casting process have been computed to estimate the thermal characteristics of a caster roll. To calculate the rolling force, the relationship between the flow stress and strain for a roll material and a casting alloy are assumed as a function of the strain rate and temperature, because the mechanical properties of casting materials depend on temperature. Temperature field data for a caster roll, provided by the authors, were used to estimate the roll deformation. Therfore, numerical models considering the thermal and rolling forces have been developed to estimate the roll life. Roll life considering the thermal cycle is calculated using thermal elastic-plastic analysis results. The roll life is proposed in terms of roll revolution in the caster roll models with and without the fine crack failure on the roll surface. To obtain plastic strain distributions of the caster roll, thermomechanical properties of a roll sleeve with a copper alloy are obtained by a uniaxial tensile test for variation of temperature. The proposed analysis techniques have improved in caster roll design.

In this age of technology and communication convergence, you cannot help but be involved in technologies and innovations that revolve around computers, cellular phones and the World Wide Web. But as we go around our daily lives with these technologies and what not, there are times that we begin to feel really paranoid on our own safety.

May it be our physical safety or the security of our personal hardware and software. What is cyber security all about? It is in fact protecting your personal information or any kind of digital asset stored in your computer or in any digital storage device.

The first thing that you will have to understand is the kinds of threats that you could encounter in cyber space. There are different kinds of threats and each one has their own degrees of seriousness which require their own levels of solutions. The higher level the threat, the more advance or complicated the approach to implement safety measures to protect yourself from such harm.

From simple malicious codes, otherwise called as malware and spywares to serious virus that can erase the whole contents of your computer and hackers that can access and use your personal information for their own personal gain, these are the risks that you will need to address.

Oftentimes, those malicious codes or malware pass through your security system when you access a particular website or even when you open an email. These codes, exploit the loopholes in various applications and insert themselves within the computer system which enable them to replicate and infect other computers by attaching themselves to the emails that you send out or through your local network. These malicious codes are sometimes quite tricky. They claim to do something but instead they will go on a totally different path in infecting your system. These malicious codes are not isolated to malware and spyware but also refer to virus and worms which are deadlier and cause more harm.

Even though those malicious codes are quite harmful, another dangerous intruder would be hackers or attackers. No matter how you look at it, virus and worms can only do what the original programmer has intended it to do. But hackers are people and they can get the information they want and use it for their own benefit. Sometimes hackers are just testing their skills and deliberately invade your system not because they want your info for personal gain but because they are just plain curious or are just doing some mischief.

It is these kinds of things that you need to avoid that is why you have to know about cyber security and know how to handle the various threats. You will need to know how vulnerable your computers are. You have to loon into your firewall and virus protection software to se if your current setup can prevent attacks from the outside.

This is why it is important to continuously update your software since new threats are being created everyday and having an updated system can help protect you from being attacked. Another precautionary measure would be to create passwords. The passwords will serve as a deterrent and help you keep your whole system protected.

With proper protection installed, you can keep your files and information safe. It is very important that you keep in mind cyber security. Cyber security is all about keeping your information safe from those who wish to access them. It is an important aspect of our lives and should never be disregarded most especially in today’s computer age.

Pocket PCs are small devices but is very powerful that it holds almost all of your activities, personal information, and business matters inside its bin. For executives and aficionados, Pocket PCs are already part of their lives. They can’t leave the house without their most priced Pocket PCs. Connecting to the web or checking an email are just one of the many wonders of Pocket PCs. With all these, have you ever considered the security of your Pocket PC?

Convenience equates to risk. Admit it. A Pocket PC is one very convenient way of connecting to the world without just a click of a button. It offers more possibilities attached with convenience. Although, these added conveniences puts an owner at risk. In addition to security problems and threats that you have to face regarding your desktop computer, you can have the same problem with your wireless device through networking.

The smaller the size of your device, the easier it is for your Pocket PC to become more vulnerable to the naked eye – stealing it or file corruption. You have to protect your device in three security levels namely: network, data and physical.

Network security refers to the assurance that the device will not fall into the wrong hands and other people won’t be able to use it to tap into your network. To avoid such internal problems, you have to take some steps in protecting your entire network by considering some of the factors below.

• Disabling WiFi and Bluetooth connection when not in use. This is helpful in saving your device from unwanted outside connections, increasing the life of the battery and stabilizes further security.

• Use notification and monitoring programs to track and detect hidden activities done in your Pocket PC.

• Administrators must establish a governed policy for the handheld device that will connect to the network.

• Always update your LAN driver in order to use the WPA or WiFi Protected Access instead of using WEP.

• Use private networking virtually to be able to connect to your company network.

Data security refers to the assurance of the device to be safe in case it falls to the wrong, prying hands. Even if the OS is accessed, you’ll have the feeling that your business and personal data will not be accessed. Managing this can be easy by doing the following:

• Store your sensitive data on your memory card then remove it when not in use. Make sure that the memory card itself doesn’t get lost.

• Don’t allow any access to applications that might be used to read important data. Use a software like PDA Defense.

• Always see to it that sensitive data are encrypted wherever it is stored.

Physical security refers to the protection of the device from theft or loss and prevents OS accessibility in cases of the device falling into other people’s hands. This is also considered as your first line of defense.

• Store and carry the device securely. Never let your handheld device just hang around your pocket or kept inside a shoulder bag. It’s better to keep it very close to the body as possible or if not, put it in a briefcase that’s also secured with a pin number or attach a PDA case to your belt.

• Prevent OS accessibility. You can at least put on a password or security pin code before opening the device. Use a very strong supported password.

Keeping your family safe today takes on another additional front – online or the Net. The perils that you and your family face whenever anyone is online are just as dangerous as in real life. There simply is a need for cyber security to minimize, if not totally deflect, these dangers.

Cyber security is not just to protect you and your children from online dangers. It is also to ensure that your computer is safe and secure – from your children. By following some simple computer practices, these dangers can be lessened.

The usual safeguards may not be adequate. Children, by nature, are curious and inquisitive. They like to pry things, satisfy their natural need to know.

As parents, there is a delicate balance on how long the lease we give out to kids to satisfy their natural need and the necessity to protect themselves from the outside world and from themselves.

A child out into the Net, either playing a game, researching materials for homework or a term paper can be potentially harmed. Common accidents would be your child stumbling into a porn site, getting into malicious web pages that infect your computer, or inadvertently erasing your own computer’s files.

Mistakes like these happen and your child may not be aware of them. Or if they are, they may not inform you what happened for fear of punishment.

Another fearsome threat is the ‘online predator’. Because of the Internet’s natural cover for anonymity, these people deceive and manipulate other online users to get what they want. Adults are common victims of these people, and it follows that children are even more susceptible to their dangerous manipulative schemes.

The following are some suggested safeguards in implementing cyber security in the family.

Be involved with your children’s activities
There are some activities you can do with your kids that will in effect allow you to supervise their activities. If this is not possible, you can always monitor their computer use – which sites they visit, the activities they do online, etc. If they are using emails and chat rooms, try to follow who they are corresponding with, and whether they actually know them.

Rules and danger warnings
The children should be made aware about online dangers. They must be able to recognize suspicious behavior or activities from the Net.

This will help you set out boundaries on their computer use. Everything, of course, should be appropriate for their age, knowledge and level of maturity. It is not correct to scare them, but to make them be alert and aware. This includes sites they are allowed to visit, programs they can use, and activities they can do.

Separate accounts and other controls
Today’s operating systems already carries the option of creating different user accounts on one computer. You can create separate accounts for them to protect your own files and data from accidentally accessed, modified, or – horrors! – deleted.

If you don’t have separate accounts, consider limiting the functionality of your browser (like remembering passwords, other information, etc.) to preclude accidental access.
It is here that it is important to keep your anti-virus utility, firewalls, and other safeguards up to date and active.

Some browsers allow you to restrict viewing certain web sites and protect these settings with a password. (click Tools, select Internet Options, choose the Content tab, click Enable under Content Advisor, etc.)

Some service providers also offer services that protect children who go online. They can help filter and block sites that are not suited to children. The Internet is also full of special programs for children’s protection. Check those that suits your needs best.

Open communications and computers
Set your computer in an open area of the house where everyone can monitor anyone’s computer activities. It can deter children from doing things not allowed.

Most important, communication lines between all members of the family should be kept open. The children must know that they can approach their parents at anytime about anything they see on the computer.

This is very important, not just for cyber security, but also for the family’s well-being as a whole, whether anybody is online or not.

If you think your kids now just need to be protected from strangers offering them candy or from cars while crossing the streets, then you have another thing coming. Your children need a whole new level of protection especially in this age of computers and the internet. More and more kids are having easier access to the internet. According to some studies, more than 80% of teenagers in the US have access to the internet at home. The parents should take an active role in teaching their children proper cyber security measures.

Most of the time these kids who access the net are not careful enough when giving out personal information online. They don’t realize yet the risks of not having confidential and personal information protected online. From virus, to hackers, to identity thieves, these people are lurking in cyberspace waiting for that opportunity. I can only stress the importance of cyber security for kids.

Now there are several ways where you can help instill to your children the proper ways of accessing, behaving and protecting themselves online. One of the more common venue where your children go on the web is the social network sites where they have online profiles, photos and keep blogs or online journals. Remind your kids that not to accept all those you invite them to be their online friend especially if they don’t know that person.

The problem with these social network sites is that once you add someone as a friend, you can be viewed by friends included in his own network which most of time you don’t even know. These are venues where scrupulous individuals can gain access to your personals.

To monitor their browsing activities or encourage them to ask questions, place your computer in an area of the house where there’s heavy foot traffic. This will make it easy for them to call your attention to their monitor if they want to ask questions or show you something. This also discourages them from visiting lewd and pornographic websites.

These websites are not only inappropriate but are also a repository of malware, spyware and virus applications that can destroy files and even your whole computer system. In this regard, it would be best to use controlling mechanisms like content blockers which prohibits them to access certain websites and also monitoring application so you can take a look later what they actually look for in the net.

It is always good to engage your children in a healthy conversation about the things that did or things they can do online. This way you can teach them proper ways or help develop good habits that will ensure their safety online. You can also teach them the pros and cons of social networking, online file sharing, and even the issues of software piracy and illegal downloads. These are part of increasing their knowledge and understanding about the technology of computers and the net as well as cyber security.

You should always remember that children’s predisposition of being still curious, innocent, and sometimes their desire to be independent can cause them to be careless. That is why ordinary safeguards are not enough when it comes to protection your kids on cyberspace. The previously mentioned cyber security measures for kids are not just an introduction.

You will have to know for a fact your kids computer habits and then learn how you can better protect them.

There will be times that you have to connect to your personal computer to update or download and upload files. Occasionally, your notebook or desktop computer will serve as the power source to be able to charge your battery in your Pocket PC. Connection to your personal computer is also crucial for the synchronization of changes or update that you have made via your Pocket PC.

In this activity, you’ll just need your Pocket PC, your personal computer and a specialized cable wire that is included when you bought your Pocket PC. Oh yes, and a whole lot of patience because a task like this sometimes need sufficient self-esteem.

Before plugging anything into the cradles or ports, be sure that you have the appropriate tools first. You have to be familiar with the user guide or the manual for your Pocket PC. This in this way, you’ll become more acquainted with the important matters regarding your Pocket PC connections and specifications.

Organize the different accessories and parts which include the USB cradle and connector cable, AC adapter, and finally, the software installation CD. You need all of these just in case something comes up.

Place the software installation CD in you personal computer’s CD-ROM drive. This is the first step to be able to connect your Pocket PC in your computer. Follow these instructions clearly so that you won’t encounter any kind of problem while doing your processing.

Upon entering the CD, locate the link wherein it will show you how to install the Pocket PC software in your desktop. To help you through the entire process, an installation wizard will pop up. In some cases, you may have to restart your computer to be able to complete installation. This usually happens when your desktop computer differs from its operating system.

Plug your USB cradle into your USB port to be able to connect your Pocket PC in your computer. Next, plug the compatible end of the AC adapter in the slot of the USB cradle and one correct end of into the electrical outlet found in the wall.

Once you have done this, place your Pocket PC in the USB cradle. You can now start charging your Pocket PC’s main battery or either synchronizes it into your personal computer. Aside from charging, you can start uploading and downloading files to or fro.

Other Pocket PCs came in with Bluetooth. Connecting to a Bluetooth-enable computer is possible if your Pocket PC is capable for Bluetooth.

Once you have set up a connection between your personal computer and Pocket PC, you can have the opportunity to perform various commands and process through and infrared sensor. This only applies if both your personal computer and Pocket PC is enabled with infrared. Always read your user’s guide to become more familiar with the environment of connecting and synchronizing.

If you’re having problems with opening the installation wizard, click “start”. Select the “run” and then click on the “browse” button to be able to locate the CD-ROM drive. Choose the exe. file to start the software installation process.

Pins are considered as very fragile and sensitive. Therefore, it is a must that the contracts are properly aligned before securing your Pocket PC by pushing it down to the USB cradle.

Nowadays, many people seemed to have forgotten the importance (and the inherent dangers) of their computer’s browser. They forgot that the browser, per se, works like a two-way street. It is where cyber security should police the two-way cyber traffic.

A web browser’s main job is to find and display web pages. From there, it makes possible the “communication” between your computer and the web server where a site is located.

Cyber security risks
But, your browser is also – and this is the dangerous part – the gateway of the cyber world into your computer. And, not all of the things from the Internet going inside your computer are good. Some are downright risky.

Today’s browser is sophisticated enough, through the years of innovation, to handle the multiple applications needed to surf the Internet. Many of these try to boost up and heighten the surfing experience by enabling your browser’s functionalities.

But sometimes, these functionalities are not needed and they can leave your computer vulnerable. It is therefore safe to disable them until they are needed.

In a perfect world, one should set one’s browser security to the highest level possible. But these settings may restrict the functionality of other features and prevents some web pages to load properly. The best compromise solution would be to set your browser to the highest security level (to prevent attacks) but at the same time enabling some features to work when you need them.

Today’s many browsers are mostly graphical browsers (Internet Explorer, Firefox, AOL, Opera, Safari for the Macintosh, and Lynx for the visually-impaired users.) These are capable of playing video and audio clips, aside from displaying texts and graphics. Most have user-friendly tabs and options in choosing your preferred security level setting.

It is important to know and be familiar with your browser and how it is different from the others. It will come in handy when you evaluate and determine the features and setting most appropriate for your use.

For instance, to explore the basic security options in Windows’ Internet Explorer, you click Tools on the menu bar, select Internet Options, choose the Security tab, and click the Custom level. In Firefox, you click Tools first, select Options, and then click Content Privacy and Security tabs. The others have their own path systems.

Choosing your browser
Security should be paramount in choosing your browser. But, of course, given one’s particular needs in surfing and using the Internet, other considerations are just as important. Sometimes, a browser comes packaged with the operating system. It should not limit, however, your choice.

Compatibility – does your browser work with the OS (operating system) of your computer?

Ease – are you comfortable and familiar with the options, menus, system of your browser?

Function –will it still work if other plug-ins or other devices are installed?

Appeal – do you like how your browser looks and works?

Functionalities – Your browser should be able to give you the option of putting web sites into different segments, or zones, and define different security restrictions for each. The best protection should be to set the security to the highest level, or maintain it at a medium level.

If you know of some sites which can be classified as trusted, you can set your browser setting accordingly. You may require them to implement SSL or Secure Sockets Layer so you can verify if they are what they claim to be. Note, however, that it is good to avoid lowering your security levels with them. If they are attacked, you might be included.

You may restrict particular sites you are not sure of. Prevention is always the best cure for any disease, real-life or online.

Be careful about your Java and ActiveX controls. These scripts, used to achieve certain appearances or functionality, can be used in attacking your computer. This is also true about Plug-ins, those additional software that enhances the function of some programs. Make sure that the sites that installing them are trustworthy.

For safety, it is advisable to disable Cookies and enable them only if the site you trust requires them.

Cyber Security starts first in your browser. It is best that you start the safeguarding process from there, your computer’s door to the wide, wild world of cyber space.
