WHAT IS VIRUS?NAE GRAND CHALLENGE

SECURE CYBERSPACE

DISCUSSION ACTIVITY (5 MINUTES)

•How do you use the internet at home and how do you secure cyberspace?•How do you secure yourself against

biological viruses?

WHAT IS CYBER SPACE? WHY IS IT IMPORTANT?• Our daily life, economic vitality, and national security

depend on a stable, safe, and resilient cyberspace.• We rely on this vast array of networks to communicate

and travel, power our homes, run our economy, and provide government services.

WHAT TYPE OF THREATS EXIST?

• Intrusions into information through attacks:• Social networking sites• Emails • Browsing the web

• Send malicious software:• Viruses and worms

• Trojans and spyware

• Logic and time bombs

HOW DO YOU SECURE CYBERSPACE?

• Engineers and scientists design programs to protect communication and computer networks

• They analyze available data to create better prevention programs and design solutions.

COMPUTER VIRUS

• Infects files from visiting places online

• Spreads throughout computers using an infected file’s resources

• Detected when making unusual computer actions

• Removed by deleting all infected files

ACTIVITY (25 MINUTES)

• Explore the web to get a better understanding of computer and biological viruses .

• Compare the behavior listing the similarities and differences between the two.

• Some good resources:• http://

• http://www.howstuffworks.com/virus.htm

COMPARISON….Biological

• Can infect animals, plants, and other microorganisms

• They reproduce very quickly, but only in living hosts

• Vaccines can protect individuals from being infected

Computer • Can infect devices that are capable of being

connected to the internet or network

• They reproduce very quickly, but only if the file is run or opened.

• Antivirus programs can prevent virus code from running.

SUMMARY SLIDE • Cyberspace refers to the collection of information that is assessable on the web.

• Several types of threats exist, usually resulting from some malicious type of software.

• Engineers and Scientists secure cyberspace by monitoring network access, and designing programs that protect sensitive data or computers.

• These concepts can be related to biology by looking at how biological viruses attack the body.

• Viruses (both computer and biological) can affect the host and use it for its own function.

• Vaccines and Antivirus Software prevent viruses from spreading to more people and computers.
