Security on Free Wi-Fi Hotspot

Free Wi-Fi SecuritySo, you are in some public area and using their free Wi-Fi hotspot to surf the web. Being so convenient and comfort, you are tempted that you might as well to do a little business or check your email while enjoying the surrounding environment. Well, that’s the point of Wi-Fi hotspots; being able to take care of a few things while in a relaxing atmosphere.

However, don’t get so relaxed that you ignore security and give all your confidential information to some unscrupulous hacker. They won’t be so obvious. When you’re thinking back, why don’t you trying to remember who was around when your password was stolen, you probably won’t remember the woman in the tastefully tailored business suit, and if, by chance, you do, she won’t be the one you suspect.

The best defense is to implement some simple security practices and measures that will safeguard your business and personal information. Here are some simple hot spot security tips for you:

Beware of those around you.

When you’re considering Wi-Fi security in public places one of the first safeguards is anything but high tech. Do what you can to keep prying eyes from your keyboard and screen. You pay good money for your monthly subscription and there’s no reason to let anyone piggyback or steal your credit card number as you sign up for a daily use fee at Starbucks.

Passwords

Those of us who toil and travel are prime targets for those who may be of the persuasion to purloin. In other words, it’s quite possible to be targeted for laptop theft. Use a complex password to protect your files, folders and laptop from access by those villains of concourse and lobby. Don’t Share!

When using a Wi-Fi hotspot, make sure you disable file sharing. It might be great for the home and good at the office but it’s disaster in the making at your favorite coffee house.

Use a Personal Firewall

If you’re using a corporate laptop make sure you talk to your IT department before you install any firewalls but if the laptop you’re using is your own you can find yourself a good firewall that available and have good recommendation whether it is from user review, your laptop or your program support vendor.

Most of the reasons for using a firewall should be self-evident but, to say the least, you’ll want to be made aware of any traffic coming or going and any unusual communication between applications.

Taking Care of Your Laptop

Taking Care of Your LaptopIt is certain that every laptop owners want to keep their machine in the best possible condition. Aside from cleaning your screen and dusting the keyboard, however, you’ll need to take a few extra steps to maintain your laptop’s health:

Cooling

A laptop computer generates a lot of heat, especially when running the latest high-powered software. Too much heat and you risk damaging the internal circuitry. Always try to keep your laptop in a well-ventilated, cool environment. And ensure you don’t block the fan grills on the sides, back, or bottom of the machine at any time.

Handle the screen carefully

Avoid touching or playing with your LCD screen. Yes, it might be fun to watch the waves generated by your finger against the screen, but LCD displays are fragile devices that must be cared for.

Take care when cleaning the screen too, and use only approved cleaning materials. You won’t want to pay the money for screen repairs or, even worse – a new machine entirely.

Don’t drop it

Whatever you do, don’t drop your laptop computer! Keep it safe inside of a carrying case when moving around or traveling. Don’t leave it on the edge of a table or on an unstable support of some kind. One ill-fated drop to the floor could spell death for your mobile office.

Try to make sure the rubber feet underneath are in good condition and are still attached. This will prevent the device from sliding around accidentally.

Be careful with your drinks

If you need to have a drink while working or playing, be careful not to spill it. Your laptop computer could suffer the consequences from just a few drops of liquid poured in the right places.

While you probably do eat and drink around it regardless, you will want to occasionally wipe down the edges, the keyboard, the touchpad, and maybe even wipe down the screen to keep any dirt from accumulating.

Virus protection

Security wise, make sure you obtain an anti-virus program, and always keep it updated! Buying an anti-virus one month and not updating it for the next six really negates it purpose. Your laptop computer could be exposed to hundreds and thousands of new viruses every month if you don’t update your virus definitions.

Most anti-virus programs have automatic update methods, eliminating the need for you to have to remember to do it manually.

Avoid Popups

Pop-ups are particularly annoying on a laptop computer. Trying to close a bunch of windows without a regular mouse can be a nuisance. Many intrusive forms of advertising, and even some viruses, can install software on your machine by using various forms of pop-ups. It’s best to get yourself a blocker and avoid the situation entirely.

Use a firewall

Always utilize a firewall on your Internet or network- enabled laptop computer. Even if you use Windows built- in firewall (or purchase one from such companies as Norton), your security will greatly benefit from it.

Blocking out all the unnecessary ports and closing all the loopholes will prevent a hacker or virus from freely entering your hard drive.

 

So there you go. Combine all of the above tactics and help your laptop enjoy a happier and healthier lifestyle!

PC Crash

PC CrashIt’s very frustrating when your PC is freeze or also known as crash or hang.  The computer locks up and the mouse and keyboard do not respond. You may lose data and you certainly lose time and patience.

Fragmented disk

Too many programs open simultaneously

Low CPU speed

Corrupt files

There are many things that you can do to help your computer do what you want without testing your patience. Here are few tips that you can take to minimize the risk of your PC getting crash or freezing:

Do a disk cleanup (cache, temp files, old or unused files, recycle bin) .. click here for instructions.

Do not run any more applications at one time than you need to.

If the freezing happens consistently with one application, uninstall and reinstall it – files associated with the application may have become corrupted. Always use Control Panel/ Add Remove programs, or the uninstall program belonging to the program to uninstall a program.

If the freezing has been occurring since you installed a new program, uninstall it.

Uninstall any programs that you may have downloaded and installed in the past, but no longer use.

Free up resources – click on Run and type “msconfig” in the dialog box. Next, click on the “Startup” tab. All the programs listed here with check marks are running in the system memory. To free resources

Run ScanDisk or Check Disk

Defragment your disk.

Upgrade – If you have an older computer and are trying to run multiple applications, you may need to upgrade your computer… check the system specifications recommended for the applications you are running to see if your system is capable of doing what you are asking.

Obtain the latest drivers for your hardware – go to the web sites of the hardware manufacturers and get the latest drivers for your video card, sound card etc

Redetect your devices – remove the components from the Control Panel, System, Device Management screen. Reboot the system and let Windows redetect and add only those devices which are actually on your system.

Make sure that you have anti-virus software installed. Set it to automatically update virus definitions, to scan all incoming files, and to do a full system check at regular intervals.

Hotspots and Free Wi-Fi

Free Wi-FiWhenever you hear the word ‘Free’ in association with a product or service it’s a good idea to keep it in mind because, in truth, nothing is free. Someone, somewhere, somehow, is bearing an economic cost; and so it is with free Wi-Fi hotspots. For the most part any of the free Wi-Fi hotspots you’ll come across will have some sort of quid pro quo associated with them.

If you go to a McDonalds, for example, you can get a bit of free Wi-Fi with the purchase of a meal. In many other eating places, although not explicitly stated, it’s implied that you’re expected, as you should be, to buy something for the privilege of taking up table space while surfing the ‘net’.

Along with businesses several Municipal and International Airport Authorities, as well as a growing number of airline club lounges, are providing free Wi-Fi in an effort to sway travelers, who may have a choice between several carriers or nearby airports, to choose them. Similarly, more and more hotels are offering free Wi-Fi for their guests so, while the Wi-Fi hotspot may be advertised as free, its cost is rolled into the room rate or expensed to advertising.

There are a few venues in which, although funding may come through taxation of some sort, no direct user cost is associated. An increasing number of public libraries, for example, are offering free Wi-Fi and, amid increasing controversy, several towns and cities have either set up free Wi-Fi Hotzones or they’re exploring the possibilities.

Finding these free Wi-Fi hotspots is not that difficult. These days many public areas such as café, restaurants, hotel, library or airports will provide free Wi-Fi hotspots. But, when you’re accessing a free Wi-Fi hotspot there are a few things you should keep in mind:

Don’t expect much tech help. The waiters, waitresses or baristas may have some working knowledge but, don’t count on it, that’s not why they’re there.

Don’t overstay your welcome. If there’s a line of people trying to find a seat and you’ve been nursing a latte for two hours you, and others like you, may be contributing to the venue owner’s growing desire to start charging a hefty fee for the Wi-Fi access they provide.

Make sure you follow good Wi-Fi Hotspot Security practices.

 

So, while free may not be entirely free, it’s definitely reasonable. With a bit of planning you should be able to save yourself a few dollars a month while enjoying the ambiance of your favorite free Wi-Fi hotspot.
