Of Unsecured WiFi

9 May 2011 By Saran

wifiI didn’t realize that there are still a lot of people who do not really pay attention to securing their WiFi at home. I guess that I have always taken it for granted that once you set up any connection for home use, you install passwords and other measures to protect it. Apparently, in this day and age, not everyone has the same idea.

My colleague was telling me, just last week, that his connection at home seems to be running exceptionally slowly. First thing I asked him: are you using a wireless router? When he said yes, I asked him about a password. Just as I guessed, he said “What password?”

I moved to a new building a month or so ago and have been having problems having wired Internet hooked up. I have a mobile dongle which I can use to a certain extent but guess what? One day, I turned my WiFi on and voila, the laptop automatically connected to some fella’s wireless connection.

The fact is that this is such a common thing. Hotels, shops, and other establishments are also guilty of this neglect. I have a friend who works from home and is entirely dependent on the Internet. When her connection goes down, she simply gets in her car and drives to a nearby hotel where she can mooch.

It may seem funny or amusing, but if an unscrupulous individual gets wind of your unsecured WiFi, you just might get your bum bitten. If I were you, I’d make sure my WiFi is secure. How to do this? Let’s look at this in the next post.

The Perspective System To Fend Off Hackers

26 August 2008 By Saran

Here should be a piece of good news to WiFi networks. Apparently, finding a solution to how hackers are able to use wireless access to do their dirty work has been a growing concern. For some reason, they are able to access vital information and computers and then create havoc as they wish. Apparently they have a modus operandi to which do-gooders often have something malicious in mind, mostly to do something foolish such as injecting viruses or even accessing another computer and perhaps deleting some files without them knowing it.

But now, the Perspective System is being groomed as a low cost that will answer these issues. Apparently the biggest targets are the websites and online businesses and security in transactions is definitely in question. One this system is installed, security for various issues that include domain names system software will hopefully be covered.

“It’s very, very, very easy for someone to convince you to go through their computer” when making connections through public WiFi, said David Andersen, assistant professor of computer science. A user who thinks he is linked to an airport or coffee shop “hot spot,” for instance, might actually be linked to a laptop of someone just a few seats away. “A lot of people wouldn’t even know they’ve been attacked,” he added.

The Perspectives system is designed to aid in authenticating Web sites for financial services, online retailers and other transactions needing secure communications. By independently querying the desired site, the system can double check whether each is receiving the correct authentication information, called a digital certificate.
