Internet

• Positive: venue where people get together to communicate, exchange information, entertain, transact business, and understand how the world operates.

• Negative: playground of crooked individuals and ruthless firms who take advantage of the freedom it maintains as well as its many weaknesses.


Privacy?

• E-mail is completely insecure. • Each e-mail you send results in at least 3 or 4 copies

being stored on different computers. • You can take measures to protect your e-mail.


Cyber Security

Unfortunately, there's no 100% guarantee that even with the best

precautions some of these things won't happen to you, but there are steps you

can take to minimize the chances.

Cyber Security

• protecting digital information by preventing, detecting, and responding to attacks

• recognize the risks and become familiar with terminology associated with them


Security Settings

• High, Medium, Low• Trust sites vs.

Restricted sites• Internet & LAN

content• Firewall• Filters


Malicious Individuals

• Hacker, attacker, or intruder – exploit weaknesses in software and

computer systems for their own gain– intentions: sometimes benign and

motivated solely by curiosity– actions: typically in violation of the

intended use of the systems they are exploiting


Malware

• designed “to wreak havoc on personal computers and networks” by attaching to programs (“hosts”) and spreading from one program or storage device to another

• ranging from silly pranks to data destruction/ theft


Malware

• Virus: attaches to various files and executes (infects the computer) when the host programs are run (or an email attachment is opened or a particular web page is visited)

• Worm: propagates without user intervention via email, web sites, or network-based software, clogs the system via numerous reproductions

• Logic Bomb: lies dormant until triggered by a certain event

• Trojan Horse: unsuspicous delivery program of malware


Spyware & Key Logger

• Spyware (also called sneakware or stealthware) - software that comes hidden in free downloadable software

– tracks your online movements– mines the information stored on your computer– uses your computer’s CPU and storage, slows it

down• Key logger, or key trapper, software, -a

program, when installed on a computer, records every keystroke and mouse click.


Spyware

• record keystrokes and steal private information for advertisers, hackers, and cyberthieves

– Cookie - a small record deposited on your hard disk by a Web site containing information about you and your Web activities.

– Adware - software to generate ads that installs itself on your computer when you download some other (usually free ) program from the Web.

• Earthlink (ISP) study: average computer harbors 26 spyware programs


Myths

• Anti-virus software and firewalls are 100% effective. • Once software is installed on your computer, you do

not have to worry about it anymore.• There is nothing important on your machine, so you

do not need to protect it. • Attackers only target people with money.• When computers slow down, it means that they are

old and should be replaced.


Tips

1. Perform basic computer maintenance– firewall, data encryption, regular update of security patches – regularly run anti-virus and anti-spyware software

1. Don't open files from strangers/ unreliable sites– E-mail and IM – verify first

1. Help fight spam and online scams– use filters– be wary of phishing– check for secure pages (lock icon), server authentication,

and message integrity– review the privacy policies of websites before entering

information


Tips

4. learn how to protect yourself from adware/spyware– Regularly run anti-spyware software– read license agreements of freeware against attached

spyware4. take precautions when you go wireless

– convenient but with security risks

4. password-protect your computer—and lock it– as first line of defense

4. back up your work


Safeguard your passwords!

• Guidelines from Learn the Net.com:1.Although passwords should be easily

remembered, do not use passwords that refer to easily obtainable personal information, such as your name, address, phone number, or birthday.

2.Avoid using common words.3.Passwords should be at least six

alphanumeric characters – meaning, combine upper and lower case letters, numbers, and symbols, e.g. 2fjm0x@Ic. NOTE: Passwords are case-sensitive.


Safeguard your passwords!

• Guidelines from Learn the Net.com:4.Ideally, use a different password for each

service you register with. For sensitive accounts, such as financial services, change your passwords frequently.

5.Never ever disclose your password/s. Don’t have your computer “remember your password”.
