8 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.

9 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

10 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.

11 Tips to Avoid Spam & Phishing Scams Dont 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 Dont buy into any email promising you large sums of money if you email them personal information Email that starts dear customer is NOT legitimate!

13 Exercise #1 How to Spot an Email Scam

14 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.

15 Viruses Enable file extension viewing in Windows so you know what youre getting! Dont open email attachments that seem unusual - what you dont open cant hurt you! Keep antivirus software current! Set up automatic updates for antivirus software and Windows when possible

24 Okay, enough about SPAM What about SPYWARE and other web browser evils?

25 Web Browser Woes Spyware Anti-spyware software Adware Anti-adware software Intruders/hackers IE security options firewalls

26 Spyware 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. --Wikipedia

27 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. -- Pew Internet & American Life Project

28 How to Combat It Anti-Spyware Software free/shareware - SpyBot commercial - Norton Alternative Browsers Firefox, Opera, Netscape Check your ActiveX settings Look for https:// in the URL when ordering or entering personal info online!

29 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.

30 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

31 Anti-Spyware Software: Some Good Options Spybot freeware, no requirements Microsoft Anti-spyware freeware Must have a registered version of Windows to install

32 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. --Wikipedia

33 Adware Is Not Spyware - Usually! Often the price you pay for freeware -- as with Eudora or Netscape Adware passes Info on to advertisers Doesnt put malicious software on your computer Has come to be associated with spyware

37 Pop-ups Not all are created equal! Good pop-ups: part of a program (as with videoconferencing part of a sign-up or sign-in system Bad pop-ups ads spyware or malware

38 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

39 Firewalls 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 dont need another on your computer

40 Firewall-Related Problems May not be able to connect to sites like the Infopeople webcasts Videoconferencing software often wont work File and printer sharing may not work
