Setting up a Business Network

Filed under: Data Doctors, E-mail, Internet, PC, Passwords, Tips, Wireless Internet — admin @ 3:32 pm

Setting up a small business network allows you to get more out of your systems and components, you’ll be able to access the internet on any computer, as well as share files on computers within the network.

The first thing you need to do is make sure you have the correct equipment for your needs, If you want your business wired, Ethernet cables will be needed, if you choose to go wireless, a wireless router will be required. You are also able to use a combination of the two.

There are two ways you can set up your network:

PEER TO PEER

When using a peer-to-peer setup, each computer acts as both the client and server, and is able to communicate directly with the other computers on the network. You will only need a router, and have the computers on the same work or homegroup, and enable print and file sharing. Windows offers a Network Setup Wizard that you can access to walk you through your setup.

CLIENT-SERVER

A client-server setup allows several computers to connect to a single sever where public data can be stored. This is more typical in a larger office setting. For this set up a server is needed, a computer with a ‘server-friendly operating system’ can be used. (For little companies, Windows XP, Vista or 7 Professional will work just fine.) Making sure everything is hooked up properly is the main thing, as well as making sure all of your client computers have separate names.

Setting up a business network is all a matter of preference and layout, call your local IT Company with any questions or concerns!

Open your eyes when surfing the internet!

Would you cross the roads with your eyes shut?  Open your eyes when surfing the internet!

Reading the Star Tribune on Sunday, we learned that Minneapolis is now ranked the seventh-riskiest city in America for cybercrime!!  Eeek, now that is hitting a little close to home.  Every day we are hearing or seeing in the news something about a new virus attack or online threat to our computers.  It’s not like all the computers in Minneapolis are going to grow legs and arms to strangle us.

The Minneapolis area does have one of the highest populations of in-home computers and computer users in the nation.  Minneapolis is growing to become known as a very internet savvy city.  Due to this, we are more likely to encounter spyware, spam emails and other viruses.

Keep yourself safe by never fully opening an email, use a preview window to read your messages  (both entourage and outlook allow you to do this), do not log into confidential sites when you are on an open wifi network unless it is secure, and make sure you know what you are downloading before you hit ok.  It’s just like you’re a kid again and your mother is teaching you how to cross the road. Look both ways to ensure that there are not any viruses coming before you begin to access the site and keep looking both ways as you access the site to make sure a virus doesn’t pop up out of nowhere.  If you are nervous or have questions, ask a computer expert. We’re here to help and answer questions.

Is airline Wi-Fi any good and is it safe?

In-flight Wi-Fi brings a whole new meaning to the term ‘cloud computing’! In past years, the offerings were expensive, restrictive and inconsistent. But not anymore!

In our experience, speed, reliability and cost have all been reasonable. We’ve tried Gogo and expect Row 44 to be good, too. Just check with your airline before you go to see what is being offered.

Although Wi-Fi on airlines only works above 10,000 feet, the providers and airlines are not currently blocking access to any specific content or websites and are relying on passengers to behave themselves (this could change)!  One exception is voice traffic. The airlines decided that their passengers didn’t want to get stuck next to loud, obnoxious ‘deal makers’ flapping their gums about their latest conquests during these long flights.

Any device that is Wi-Fi enabled and has a browser can make use of the connection:  laptops, Netbooks, smartphones and even the iPod Touch and some handheld gaming systems should work.  You must have a browser in to get past the ‘I Agree’ terms of use gateway page.

As far as safety goes, this shouldn’t be approached any different than any other public Wi-Fi connection.  If you aren’t careful, you could expose your computer to others on the flight, just like in the airport or at a hotel (our column on public Wi-Fi safety is posted here: http://bit.ly/2ldfHp.)

Be very mindful that those in the row behind you can easily see through the gaps in the seats to your screen or lots of folks if you are seated in the aisle seat.  This means you should avoid typing in any sensitive information or websites that will display sensitive information.

As should be expected, if your company requires you to use a VPN (Virtual Private Network) to connect to the company network, you may have problems getting it all to work depending upon how restrictive your IT department has set the VPN to be (check with them before your flight for the best results).

Am I really safe using public WiFi?

How many times have you logged onto public WiFi and wondered if you’re safe and secure? In order to intercept your transmissions, a hacker would have to install special software called a ‘packet sniffer’ which secretly copies unsecured packets transmitted on the same network or create a ‘man-in-the-middle’ exploit to trick you into connecting directly to their computer instead of a wifi access point.

Packet sniffers are readily available on the Internet and any motivated 14-year old could figure out how to use one, but that doesn’t mean that everyone around you has one.

The other issue is that even if someone can see what website you are surfing while you are at the airport, no harm is done unless you access your e-mail account, an online banking site or other normally secured resources on the Internet.

Secured sites on the Internet will show up as ‘https:’ instead of ‘http’. If you need to type sensitive information into your computer while on public WiFi, make sure you are doing it on a page that has the ‘https:’ prefix so that your transmissions are being encrypted.

Sadly, many web-based e-mail systems have a secured login page, but once you get past the login, the rest of the pages are not secured. The easiest way to tell if your webmail system is secure at all times is to log in, then go to your Inbox and see if the ‘https:’ remained in the URL.

If your webmail does not encrypt pages after the login screen, then you need to think twice about using it on public wifi networks without adding additional security software, such as VPN – Virtual Private Network software (more on this later).

To avoid the ‘man-in-the-middle’ attack, be very careful to look at the icon next to each available connection when you are attempting to connect to a wifi network. A fake wifi connection will appear as two computers instead of something that looks like an antenna.

Overall, you are pretty safe using a public wifi. Just remember to watch what you click and don’t go into confidential files without a secure login while you are public.
