first up… Getting a Grip on Email!
What Is Spam?
Spamming is the use of any electronic communications medium to send unsolicited messages in bulk. While its definition is usually limited to indiscriminate bulk mailing and not any targeted marketing, the term "spam" can refer to any commercially oriented, unsolicited bulk mailing perceived as being excessive and undesired.
How Much Spam?
Spam accounted for 77% of all email traffic in 2004
Telephone-based survey of adults who use the Internet found that more than 75% receive spam daily
The average spam messages per day is 18.5 and the average time spent per day deleting them is 2.8 minutes
More than two in five spam emails are medically related
What Is Phishing?
Phishing (also known as carding and spoofing) is an attempt to fraudulently acquire sensitive information, such as passwords and credit card details, by masquerading as a trustworthy person or business in an apparently official electronic communication, such as an email or an instant message. The term phishing arises from the use of increasingly sophisticated lures to "fish" for users' financial information and passwords.
Tips to Avoid Spam & Phishing Scams
Don’t open strange attachments
Never email personal or financial info
Keep virus software up-to-date
Never click on links in email that say “click here” or “login here”
Don’t buy into any email promising you large sums of money if you email them personal information
Email that starts “dear customer” is NOT legitimate!

Exercise #1 How to Spot an Email Scam
What Is a Computer Virus?
A virus is a self-replicating program that spreads by inserting copies of itself into other executable code or documents. A computer virus behaves in a way similar to a biological virus, which spreads by inserting itself into living cells. basic rule is that computer viruses cannot directly damage hardware, only software is damaged directly.

Okay, enough about SPAM— What about SPYWARE and other web browser evils?
Web Browser Woes
IE security options
What Is It?
“ a broad category of malicious software intended to intercept or take partial control of a computer's operation without the user's informed consent. While the term taken literally suggests software that surreptitiously monitors the user, it has come to refer more broadly to software that subverts the computer's operation for the benefit of a third party.”
How Pervasive Is Spyware?
49% of Internet users see spyware as a serious threat to their online security
63% of Internet users have been plagued by spyware in the past year
81% of Internet users say they have stopped opening email attachments unless they are sure these documents are safe
18% of Internet users say they have started using a different web browser to avoid software intrusions.

How to Combat It
free/shareware - SpyBot
commercial - Norton
Firefox, Opera, Netscape
Check your ActiveX settings
Look for https:// in the URL when ordering or entering personal info online!
What is ActiveX?
A Microsoft technology used on the Internet to make interactive web pages that look and behave like computer programs, rather than static pages. ActiveX controls may be used with Microsoft's Internet Explorer browser to interact with web pages. ActiveX controls provide functions similar to Java Applets.
Pros and Cons of ActiveX Controls
Good: view sophisticated web content
Bad: lack of security
Good: interact with anything on the desktop
Bad: interact with anything on the desktop - making spyware able to exploit it
Anti-Spyware Software: Some Good Options
freeware, no requirements
Must have a registered version of Windows to install
Adware - What Is It?
“ Adware or advertising-supported software is any computer program or software package in which advertisements or other marketing material are included with or automatically loaded by the software and displayed or played back after installation or in which information about the computer or its users activities is uploaded automatically when the user has not requested it.”
Adware Is Not Spyware - Usually!

Adware passes Info on to advertisers
Doesn’t put malicious software on your computer
Has come to be associated with spyware
Commercial: Norton, McAfee

What to Do About Pop-ups
Built-in browser pop-up blocking
most new browsers offer this, including IE
Pop-up blocking software
many freeware, shareware options
commercial Internet security packages also offer pop-up blocking
Toolbars - free from Google, Yahoo
you only need one
Block attempts to hack your computer (zombie computers)
Can block good content as well as bad
You only need one firewall - if your local network is running one, you don’t need another on your computer
May not be able to connect to sites like the Infopeople webcasts
Videoconferencing software often won’t work
File and printer sharing may not work
Is Windows Firewall Enough?
It won’t prevent viruses or spam from reaching your inbox
It won’t stop you from opening bad attachments
It will let you know when bad stuff attempts to get out & will block it
It will provide you with a log of suspicious activity
