Internet Security Basics 101

The explosive growth of the Internet has meant that thousands of people are today experiencing the joys of being online for the first time. With growth there always comes pain. Be it your growing pains as a child or the growth and development of this part of our culture called the Internet.

Firstly we need to quickly explain what the Internet is and where it came from. The Internet is the offspring of a military project called Arpanet. Arpanet was designed to provide reliable communication during global nuclear war. A vast network of interconnected computers was set up all over the world to allow the various branches of US and NATO forces to communicate with each other.

Nuclear war never came (thankfully) and the world was left with a massive network of computers all connected together with nothing to do. Colleges and universities started to use these computers for sharing research internationally. From there it grew and spread outside colleges to local homes and businesses. The World Wide Web was born and its father was a guy called Tim Berners Lee.

When you're connected to the Internet you're sharing a vast network with hundreds of millions of other users. This shared network provides resources that 15 years ago were never thought possible. Unfortunately when something is shared its open to abuse. On the Internet this abuse comes from hackers and virus creators. Their sole intent is to cause chaos and/or harm to your computer system and millions of other computer systems all over the world.

How do you combat this? You need an Internet security system. This might sound complicated but your Internet security system will be quite straigtforward being comprised of just 2 - 3 Internet security products. We'll look at each of these products in more detail now:

AntiVirus Software

The first and most critical element of your Internet security system is antivirus software. If you don't have up-to-date antivirus software on your PC you're asking for trouble. 300 new viruses appear each month and if you're not constantly protecting your system against this threat your computer will become infected with at least one virus - it's only a matter of time.

Antivirus software scans your PC for signatures of a virus. A virus signature is the unique part of that virus. It can be a a file name, how the virus behaves or the size of the virus file itself. Good antivirus software will find viruses that haven't yet infected your PC and eliminate the ones that have.

Antivirus software can only protect your computer from viruses trying to infect it via email, CD-Rom, floppy disk, Word documents or other types of computer files. Antivirus software alone will not keep your computer 100% safe. You also need to use firewall software.

Firewall Software

The use of firewall software by home computer users is a relatively new occurence. All Internet connections are a two way process. Data must be sent and received by your computer. This data is sent through something called ports. These are not physical things rather aspects of the way your computer communicates online.

Firewall software watches these ports to make sure that only safe communication is happening between your computer and other computers online. If it sees something dangerous happening it blocks that port on your computer to make sure your computer stays safe from the person who is trying to hack into your system.

An easier way to understand a firewall would be to picture your computer as an apartment complex. At the front door of this complex there is a security guard. Every person who enters the complex must pass this security guard. If the security guard recognizes the person entering as a resident he allows them to pass without saying anything. If, however, the person entering the complex is unknown to him then he will stop that person and ask for identification. If they have no business being at the apartment complex he escorts them from the building.

If you are not currently using firewall software your computer will get hacked into - that's a guarantee.

PopUp Blocker

You can get a good popup blocker at no cost. An easy way to do this is to install either the Google or Yahoo toolbar. Both of these come with popup blockers built in. Popups are not necessarily dangerous but are a nuisance and using either of these toolbars will make your life that bit easier.

A simple rule for practicing online security is: "If in doubt then don't". If you don't recognize the file, the email address, the website or if your gut feeling says "no" then don't click that button.

Data Recovery and Causes of Data Loss

Although processing and storing data on a computer is efficient, cheaper and easier, proper care should be taken to protect it from damage. For example, imagine a financial institution having credit and debit information of all the customers stored on a computer. If the company does not have any copy of these data elsewhere and the computer breaks down, there would be no way they could track down these information details. As a result, there is a risk of not knowing who are the creditors and debtors and the company stands a chance of going bankrupt.

Causes of data loss

The information on a computer is stored on hard drive. Data loss on a hard drive could happen due to a variety of reasons and some of them are as follows:

• Virus on the computer


• Formatting of the hard drive


• Physical damages to the drive


• Hard drive head crash


• User might have inadvertently deleted the data on the drive


• Power failure before the user could save the file

The data could also be stored on removable media such as CD, floppy or pen drive. The data on these devices could also be lost due to some of the above reasons. The loss of crucial data necessitated the need for a means to recover them and this led to the development of various techniques to retrieve the data.

Data Recovery: The Process Involved

As the name implies, data recovery is the process of retrieving the data from a crashed hard drive or storage device. There are various methods that can be employed for data recovery depending upon the type and severity of data loss. For example, when data on a hard drive is lost due to software corruption by virus, data recovery is usually done through parallel reinstallation. In this process, a fresh copy of the operating system is installed without deleting the existing one. Since the previous copy of operating system has crashed, the data stored in the hard drive is accessed and retrieved through the new copy of operating system.

People generally assume that data recovery is not possible in a lot of cases such as data loss due to power failure or formatting of hard drive. However, in most of these cases, data can be retrieved with the assistance of a data recovery expert. There is also data recovery software available in the market that helps you with the process even without the assistance of an expert.

Service Offerings

There are various companies providing data recovery services in the market. However, it is important to choose a reliable data recovery company. Otherwise, you run the risk of losing your data forever or end up paying more than what it is worth.

Fields Data Recovery has been in this industry since 1992 and has its presence in a lot of countries around the globe. Excellent recovery rate and high profile clients such as IBM, Reuters, Warner Brothers Entertainment, etc. stand as a symbol of credible service offered by them. They provide quality service in recovering data from hard drive and all types of removable media.

Precautionary Measures

Instead of losing your important data and then worrying about retrieving it, you could try to prevent the problem even before it strikes. Here are some of the useful tips to avoid data loss:

1. Always have a back up of your important data. This way even if you lose the data on the hard drive you can use the copy of it stored on the CD.
2. While travelling with your laptop or moving your desktop, be careful to avoid jerks that could disturb the hard drive head and cause data loss.
3. Virus mostly spreads through e-mail attachments and might destroy the data on your computer. So avoid opening e-mail attachments from strangers.
4. Have an updated copy of anti-virus software on your computer that can prevent virus attack.

Sensors and How They are Used

A sensor is a device that responds to an input quantity by generating a functionally related output usually in the form of an electrical or optical sight. There are many different types of sensors: position sensors, load sensors, tilt sensors, and vibration sensors to name a few, and they are present in multiple fields that warrant the technology.

In the past twenty years there has been tremendous growth in the number of products and services that utilize information acquired by monitoring and quantifying different types of sensors. Sensors have been produced to match the need of these afore mentioned services, and is referred to as sensor technology. Sensor technology encompasses a broad range of services including those applicable in the environment, medicine, commerce, and industry.

Organizations of the relevant areas are realizing the implications of encouraging the growth of sensor technology. Most sensors are electrical or electronic, though other types exist. Sensors are used in everyday life with applications in areas such as automobiles, machines, medicine, and robotics.

Sensor Networks
Sensors usually work in a network, called sensor networks. A sensor network is a group of specialized transducers with a communications infrastructure intended to monitor and record conditions at varying locations. Areas commonly monitored include temperature, humidity, pressure, wind direction and speed, illumination intensity, vibration intensity, sound intensity, power-line voltage, chemical concentrations, pollutant levels, and vital body functions. This intelligent is achieved by using solely or a combination of the tilt, load, vibration, and position sensors mentioned in the introduction.

A sensor network can be broken down further into multiple detection stations called ‘sensor nodes.’ Each sensor node is minute, lightweight, and portable. Each node is equipped with a transducer, microcomputer, transceiver, and power source. The transducer generates electrical signals based on sensed physical effects. The microcomputer both processes and stores the sensor output. The transceiver (being hard-wired or wireless) receives commands from a centralized computer and transmits data back to the computer. The power for each sensor node is derived from the electric utility or from a battery.

Applications

Sensors and Sensor Networks can be applied to:

- Industrial automation
- Automated and Smart homes
- Video surveillance
- Traffic monitoring
- Medical device monitoring
- Monitoring of weather events
- Air traffic control
- Robot control

Types

Sensors are classified according to the type of energy transfer they detect:

- Thermal
- Electromagnetic
- Mechanical
- Chemical
- Optical and radiation
- Acoustic
- Motion
- Orientation
- Distance

How To Improve Customer Trust In Your Online Shop Or Auction Website

Internet fraud is on the rise. As fraud becomes more profitable, it also becomes more sophisticated and difficult to detect. As a result, tech savvy web users are looking for trust worthy sites to shop at. But how trustworthy are the current solutions? Are they just superficial but ineffective against the ever technically improving internet-fraudsters?

Typically, a number of means are employed to improve the trustworthiness of a site. These include superficial approaches like designing a site that looks professional, using recognized payment processors like Paypal etc. While these measures do not improve the sites security they may improve customer confidence as a professional looking site must be operated by a professional reputable company. At least that is what some customers will think.

Certificates are used to further increase customer confidence. Many online users are becoming familiar with the use of certificates and the small padlock that appears near the address bar to signify that the site is secure. While certificates and SSL can increase the integrity of data flowing to and from the website, they do not guarantee that the site does not have a security hole. They do not guarantee that the company that purchased the certificate is reputable. Certificates give a false sense of security to customers as in themselves, they cannot secure a site.

Does the software platform you use improve security? Not many companies code their own online shop from the ground up. Even fewer do it well enough to be secure. Most companies buy a pre developed package like CubeCart etc. These packages often do not get upgraded to plug the latest security threats. While this approach offers customers a professional interface, it does not improve security.

Site security scanners are another way to improve customer confidence but do they improve site security (typically by displaying a hacker proof logo or something similar). In cases where shops use standard packages like CubeCart, these scans can detect versions and potentially spot problems. These scans cannot effectively cover all types of sites and may be ineffective on certain sites. Only one security vulnerability needs to be missed for a site to be insecure. While these scanners cannot detect all security vulnerabilities, they can produce a level of confidence for potential customers.

Website hosting providers. Many web traders place a lot of faith in their online hosting providers. There are however a lot of providers out there that do not secure their systems properly and leave their customers open to certain types of attacks. This is an area that your potential customers may not be able to see. While the hosting agent you choose may not help improve the trust of your customers, it may improve your site security.

A further way of improving site security and trust is to have the site/product/service recommended by customers that have used the site previously. This is how eBay gains the trust of potential buyers, by using their feedback system. The only way for this type of system to work for home grown sites is if the feedback system is managed by a trusted 3rd party. This type of feedback system is available free from Pubble Hill and can be integrated into any site using their free API. The API includes features that also allow your site to automatically upload products to the Pubble Hill directory. They also offer the worlds only independent search engine that allows customers to search for products based on the sellers reputation.

In conclusion, there is no real security measure that will make your site bulletproof. However, a combination of all the above will help increase your customers confidence and make your site more secure.

Is Your Internet Surfing Really Private?

Imagine you are surfing from your personal desktop or laptop, no one looking over your shoulder or sitting nearby. You are all alone. Wrong! From your computer identity to your personal details, you are no longer anonymous on the internet. Here's the company that you keep on the internet preventing you from surfing anonymously.

Hackers take advantage of your computer vulnerabilities to install small programs on your computer which record and relay your keyboard input. Then your information and passwords are used to hack into your bank accounts, credit cards and other financial institutions and cause you immense loss. In a similar manner, your lack of anonymous surfing leads to your professional data being stolen by hackers.

Advertisers find easy access to your computer and follow your internet activity to annoy you with popups or banner ads or both, even when you are not online. You also get bombarded with junk emails advertising products making your mailbox a spammers' heaven. Without anonymous surfing, you will find advertisers accompanying you on the web at all time.

Hijackers use tracker cookies planted into your computer to stop you from anonymously surfing. These cookies follow your surfing patterns and then hijack your searches, with or without your knowledge. Hijackers don't take your consent to install cookies and you end up on websites of hijackers' choice. Do anonymous surfing to prevent hijackings.

Con Artists send you mails disguised as those from your bank and other financial companies. Some conmen even send mails announcing you as winners and asking for your financial details. Once you give financial details you find yourself conned out of your savings. You need to practice anonymous surfing to avoid such traps.

Mischief makers abound on the internet looking for browsers without anonymous surfing habits. They use unauthorized downloads to infect your computer with viruses, worms, trojans, spyware and other harmful programs. This can lead to loss of control over your own computer. You need to keep your computer safe from mischief makers and do only anonymous surfing.

Family and Work colleagues can easily trace your internet activity from the tracks you leave on your computer. The only way to prevent this is to do anonymous surfing.

With so many disrupters and scammers, not to mention people you know, following your internet browsing you can't have any internet privacy. Safeguard your web privacy by using anonymous surfing software. Anonymous surfing software will ensure that not only is your browsing private, your data and information is also safe and secure.

If you are not using anonymous Internet surfing software, your online activities are easily tracked. Anonymizer Anonymous Surfing is anonymous web surfing software that keeps your web surfing private and secure.

Anonymizer Anonymous Surfing combines thousands of private anonymous proxy servers with 128-bit SSL technology, to ensure the highest level of protection and anonymity. Anonymous Surfing hides your online identity, hides IP address, the web sites you visit, and any information you transmit.

7 Tips for Improving Your Internet Security

Here are 7 tips you should take to heart for the security of your computer and the data it contains.

1. Always make backups of your documents and other important information stored on your computer. There is always the chance that malware can damage your operating system beyond repair. Take heed. It's better to be safe than sorry.

2. Keep your Windows operating system updated with the latest security patches from Microsoft. Windows is the most popular operating system on the planet, and consequently it is the favorite target of hackers. Also locate and install patches for your Office programs.

3. Install a software or hardware computer firewall. There are no excuses for neglecting this one. If you are using Windows XP it's built in. Go to the Security Center and make sure it's enabled. If you do not have a firewall, viruses, worms, trojans, malware and adware can all easily enter your computer via the Internet.

4. Install an antivirus program and use it! Your computer is under a constant threat while online. Make sure you have the automatic update feature enabled, and schedule it to update virus definitions on a daily basis. You can also schedule scans with most antivirus software. I have mine set to scan every night.

5. Turn off your computer and disconnect it from the internet if you are not using it. Hackers can't attack your computer if it's off line.

6. Refrain from opening e-mail attachments. Don't do it even if you recognize the sender. I use the delete button judiciously.

7. Don't run programs from unknown origins. Be especially careful with P2P sites, shareware software, and freeware applications.

Follow these tips and your computer will run longer and have fewer problems.
