Deploying Skype in the Enterprise

Our goal is to enable users to enjoy Skype from as wide a variety of networks as possible,

without requiring people to understand or configure complex options such as relay hosts or

preferred network ports. In this sense, Skype is generally ‘hands-off”.

The authentic and most up-to-date version of Skype is always available directly from

Skype’s own download server at http://www.skype.com/download. From here there is a

business version available which includes the Windows Installer (MSI).

Once installed, the Skype client periodically checks to see if there is a software update

available, although system- or network administrators may disable this feature. And end

users can adjust their Skype client preferences to control how updates and patches are

handled in general.

General Guidelines

Skype wants end users and enterprises alike to have a safe and enjoyable experience using

Skype to enable communications. Toward this end, we would like to underscore the

importance of keeping your company’s computers and users safe and secure while doing

so. Here are some of the main issues to be aware of:

• Before you deploy Skype in an organization, be sure it is an authentic copy. Check the

digital signature of the installer and be sure to read and accept the terms and conditions

in Skype’s End User License Agreement and Terms of Service before deploying Skype

software.

• Keep your organization’s computers up-to-date with relevant patches. Most of the

computer security problems on the Internet today can be traced back to improperly

patched computers.

• Obvious as it may sound, use anti-virus protection, even on non-Microsoft computers

such as the Apple Macintosh, and keep the virus definitions constantly updated.

• When you use Skype, know who you’re authorizing and don’t hesitate to block users

who are making unwanted contact. Keep user profiles up-to-date, but also know that

everything in a user’s profile (except e-mail addresses which are masked for privacy) are

viewable to others whose search criteria matches the information in the profile. The

Privacy Policy at http://www.skype.com/legal/privacy sets out how Skype may use end

user’s personal data, traffic data and the content contained in communication(s). You

should ensure that end users have read and agree to this policy before using Skype.

• Always authenticate other parties before beginning to discuss any confidential business

or sensitive personal information. Remember that although Skype takes care to protect

communications from unwanted disclosure, there is the remote possibility that your

computer, or those belonging to persons with whom you are communicating have been

“hacked” or compromised in some way.

• Instruct your users to choose good passwords for Skype and change them regularly.

Remember, users should never check “remember my password” when using Skype on a

shared computer.

Skype Client Notifications for New Versions and Updates

Once the Skype application is installed, it periodically checks to see whether an update is

available by default. The Skype client does not update itself. Instead, the Skype client

notifies the user when a more recent copy or critical patch is available. This gives the user

the option to upgrade.

Users may chose to disregard these upgrade notices. System- and network administrators

may disable this feature to control software installation policies. See “Enterprise

Installation and Setting Policies” below.

End users can control the Skype automatic update-notification feature by a Skype

application preference (choose Tools > Options > Advanced).

Alternatively, users may manually check to see if the copy of Skype they are running is the

most current version. There are two ways to accomplish this:

• A user may select Help > Check for Updates from the Skype main window. This will

launch the user’s default web browser and display a message indicating whether the

installed version is up to date, or

• Without launching the Skype client, a user may open the Windows Control Panel and

double-click on Add or Remove Programs. Then, the user can find the entry for Skype

and click on the entry labeled, “Click here for support information.” Follow the

hyperlink on the line entitled, “Product Updates” which launches the default web

browser and indicates whether the installed version is up-to-date.
