You don't need me to tell you that security is the #1 concern in today's networks. With that in mind, your career path must include some security certifications, or you will be left behind.Cisco's Cisco Certified Security Professional (CCSP) certification demands a candidate be well-rounded and well-versed in Cisco security measures. Besides the difficultly we've all come to expect from a Cisco exam, this five-exam path covers every major aspect of network security (from Cisco's viewpoint, anyway!)You must hold a valid CCNA certification to earn your CCSP. Typically, the first exam CCSP candidates take is Securing Networks With Cisco Routers An Switches (SNRS), followed by Securing Cisco Network...

WAP-An Overview Wireless Application Protocol commonly known as WAP is used to enable the access of internet in the mobile phones or PDAs. WAP is an international standard for the devices that use the wireless communications. Nowadays internet has prevailed in our lives so much that it has become difficult to live without it even for a while. But we can not have access to our personal computers all the time to connect to the internet, like when we are on the go or we are out of town for while and we want to check our mail or want to make a flight-reservation online or chat to an associate or a friend. In the situations like these, WAP comes in handy. All we have to do is to carry a WAP enabled...

Ample media attention has been focused on security issues such as viruses, phishing attacks and theft of sensitive customer information from large databases. The proliferation of Spyware and Malware (malicious software) has also garnered media attention. Another major, yet seldom discussed threat which goes on largely ignored outside the IT community is the theft and redistribution of email.To make a product which best addresses the quiet rise in email thuggery, sometimes we have to think like a criminal or mal-doer. How would these digital thugs hunt for Personal Identifying Information (PII), company assets or secret email conversations intended to be read ONLY by the recipient? Consider this...

War drivers are in the business of finding wireless access points, documenting them and uploading their locations to the web. Why would someone do this, well for several reasons:First they want free internet access. Next they could just be war driving as a hobby; finally they could be targeting your network for financial gain. One of the most asked questions is how do you stop hackers from trying to hack your wireless lan and how to catch them in the act.Stopping Wardrivers:1. Use directional antennas: One of the most under stated uses of directional antennas are how they keep your wireless signal within your area of operation. If you are using a Omni directional antenna that is causing half the...

A recent survey from shows that protecting your wireless network has become one of the top three issues in home security. According to the survey the top three concerns about home security was: * Locking windows and doors * Installing a home alarm system * Securing your wireless network. More than 40 percent of the survey respondents felt that a protected Wi-Fi network was an important part of creating a safe home. Is your neighbor using your Wi-Fi network? Did you know that 17 percent of Americans thinks it's ok to use someone else's network. The wast majority thinks using...

Because nobody wants to compromise the integrity of their network by having some hacker "borrow" your bandwidth or gain access and start snooping around you need to lock down your network. Fortunately, encryption is built into wireless technology; it's simply a matter knowing how to turn it on.Wired Equivalent Privacy (WEP) or WiFi Protected Access (WPA) The good news is that wireless technology does have pre-built security but the bad news is there's a flaw in that security. The problem lies in the fact that it's been built upon two completely incompatible standards with the result being that it's a pain in the "you know what" to set up a whole network to use encryption.Like most new technologies...

I spend a great deal of my time dealing with highly sensitive, highly confidential information. Over the years I have noticed that many of the institutions I have worked with have gone to great pains and considerable expense to make certain their computer systems have state of the art firewalls and "hacker-proof" encoding systems. Nonetheless, they continue to leak data like a sieve!How can this be? Simple, they are guarding the air conditioner duct instead of the front door.So, what do I know about it? My knowledge of the field is pretty backdoor in nature.First of all, I work a lot with people who love nothing more than to stir up hate and discontent wherever they go. They will intentionally...

Although it is relatively easy for SOHO (Small Office/Home Office) and home users to set up their own Wireless networks, the default settings on a WAP (Wireless Access Point) usually come with no security configured. As a result, if you leave these settings as they are, then this WLAN (Wireless Local Area Network) you are creating can leave you open to hackers who want to compromise your computer and/or steal information from it. As a result it is essential that you take the necessary steps to secure your Wireless network. Why do you need wireless security? In a traditional wired network you need to have physical access to the network. You either need access to a cable that is already connected to...

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...

The Nokia HS-12W is the latest Bluetooth headset from Nokia that offers clear calls and a comfortable wear. The origins of the phrase "Bluetooth" is rooted in the development of communications and electronics from the very beginning. One story has it that before Thomas Edison invented the light bulb he had one problem and that was that he hadn't invented the light socket or the light switch yet. So the day before he set out to invent the light bulb he invented the light switch and the light socket. After he completed them both, on the afternoon of that day, they needed to be tested. So he stuck his tongue in the light socket and asked his faithful assistant to throw switch. After the smoke cleared...

Insurance For Your High Speed Internet Service Connection Home wireless network security software for your DSL or cable high speed internet service is as important as having good home owners insurance. Why? Because uninsured (unsecured) high speed wireless internet connections can be used to steal valuables (information) on your computer. Not so different from a thief stealing money or jewelry from your home while you're away on vacation. Crackers - not Hackers who are actually good code makers - crack into home wireless networks for fun. And if they can't access anything important from your home computer, an experienced Cracker might use your unsecured wireless internet connection to access other...

Planning to buy a new digital camera? There are so many cameras in the market with so many different features. It is not always easy to decide what are the features really needed. I would say Wi-Fi connection is one of the important features that your new digital camera should have. In traditional Digital cameras we are using USB cables to connect with computer or printer. But in Wi-Fi enabled cameras you can connect them with out any physical connection. While sitting at the airport, take photos and mail them to your friend or save them to your online album. Regardless how much storage left in the camera, you can keep on taking photos and save them in your album. If having party at home, keep on...

Running a business from home has its advantages, including no commute, a more accommodating work schedule, fresh coffee and home-cooked meals at any time you want. But running a business from home using a home wireless local area network (WLAN) with your computer may lead to thievery of confidential information and hacker or virus penetration unless proper actions are taken. As WLANs send information back and forth over radio waves, someone with the right type of receiver in your immediate area could be picking up the transmission, thus acquiring access to your computer. Here is a list of things that you should consider as a result of implementing a home wireless network setup used your business...

There are more and more individuals opting to work from home than ever before. The advantages to this are many including avoiding the morning and evening rush hours, being able to spend time with your kids and significant other, and doing everything on your own time. Though the pitfalls are many, the one that I will be focusing on in this article is that of setting up a secure wireless network for your home based business. Right now somewhere out there, there is someone with a receiver waiting to pick up on an unsuspecting person's wireless local area network. Their hope is to garner some sensitive information that may lead to identity theft, and stolen proprietary business information. Most...

Being one of the simplest means of communications, mobile phones have become an inevitable part of our busy lifestyle. Whether you are in and out of the office - mobile phones keep you stay in touch with the people and the world. Those who drive cars also use mobile phones. But talking on a phone while driving could be dangerous and fatal. That's the reason why many leading mobile companies like Sony Ericsson, Nokia, etc., offer mobile phone car kits - these are Bluetooth devices that allow you to talk without using a wire. These hands free devices are easy alternatives for those who often use mobile phones for communications. Mobile phone car kits minimizes the chance of accidents and you can talk...

In November 2003, Toronto police arrested a man in an upscale residential neighborhood. They noticed his car driving slowly the wrong way down a one-way street. Upon stopping the car, the police discovered the driver naked from the waist down. What was he doing? He was using his laptop to download and watch "kiddie" porn from the Internet! How? He was connecting to the internet using unprotected wireless systems in the houses near the road! Here is the problem, if someone were to access the Internet and download illegal material, then disconnect and drive off; it would look like the homeowner did the downloading. How hard would it be to convince the FBI that you were a victim? This is not the only...

If you own a computer - and in today's world who doesn't - sooner or later, you will want to have access to the Internet. The Internet for some is the Holy Grail of the modern age, and not having access to it is seen in some quarters as sacrilege. But how do you connect to this Holy Grail - the Internet? You need an Internet Service Provider or ISP who will give you access and you need to decide between dial-up service which uses a regular telephone line, and broadband service which, very often comes in the form of Cable, Digital Subscriber Line (DSL), Satellite or T1 connections. Do not get thrown off by all the computer talk. The option really is yours to decide on the type of service you need...

In my experience as a computer support tech for residential customers I would estimate that 9 out of 10 home wireless networks are not properly secured and left open for anyone in range to use the internet connection or worse, hack into the files. Most people don't even realize that their network is not secure. They buy a wireless router plug in all the cables and if they get an active internet connection from all PCs then they are done. In this article I will show you how to secure your home network using Wi-Fi Protected Access (WPA) through a Preshared Key (PSK). WPA is the newest standard for securing home and small business networks. Most vendors now offer hardware and software that supports WPA...

The widespread use of Wi-Fi Technology is bringing to light many security issues that may have gone unnoticed by the average user. Traditional wired connections have obvious security precautions that most users are accustomed too, but extra measures must often be used when transferring data across a wireless, and sometimes public network. A wireless Internet connection without security can easily give anyone access to your files, email, and even gives others the ability to make changes to your computer. These types of security problems will probably have little impact on most users. Occasionally surfing the web at a coffee shop or having a wireless adapter set up on a printer will likely not bring...

It used to be that a dial up modem capable of 56 Kbps provided enough speed for most people to enjoy the Internet from the comfort of their own home. Thanks to the growing complexity of the Internet and the increasing amount of multimedia entertainment available on the World Wide Web, a mere dial up connection really doesn't satisfy anybody these days. In fact, even some of the faster means of connecting to the World Wide Web can be pretty disappointing. For example, even though DSL qualifies in many people's minds as a high speed Internet connection, it's really a light duty Internet connection at best. It may be fine for things like email, text messaging, and even moving around the occasional...

A couple of months ago I purchased my first wireless enabled laptop. As I switched it on and began setting it up I was shocked when I realized that my laptop had found and connected to my neighbours wireless modem and I was able to freely browse the internet and download data using his modem and internet connection. If I were a hacker it would not be difficult for me to hack in to his computer using this connection to his network. The Shocking Truth The shocking truth is that many wireless network users out there, and you could be one of them, are not securing their wireless modems at all. This is further confirmed by a television program I saw in which a television presenter drove down a street...

Depending upon the model, a notebook battery usually lasts from 1 to 8 hours. However, with efficient battery usage, an hour or two of battery power can significantly be increased. You can save battery power by using the built-in battery saving modes and by following good notebook battery-saving practices. Built-in battery-saving modes are Stand By and Hibernate. In the Stand By mode, open applications are stored in the RAM, the hard disks power down, the monitor switches off, but the processor goes on running. When you again perform some activity of the mouse or the keyboard, then the hard disk powers up, the monitor switches on, and the data from the RAM is activated, restoring your notebook...

Gaming laptops differ from normal laptops in both hardware and software and are tailored to power hungry gaming requirements.

This way, laptops have brought about a new dimension to the outlook of Industrial Technology...

http is hyper text transfer protocol which is responsible for transmitting and receiving information across the Internet where as https is secure http, which is used exchanging confidential information with a server, which needs to be secured in order to prevent unauthorized access. HTTP is Hyper Text Transport Protocol and is transmitted over the wire via PORT 80(TCP). You normally use HTTP when you are browsing the web, it's not secure, and so someone can eavesdrop on the conversation between your computer and the web server. HTTP can support the client asking for a particular file to be sent only if it has been updated after a certain date and time. This would be used if the client has already...
