5 Why Be Concerned about Network and Internet Security? Security concerns related to computer networks and the Internet abound Computer crime (cybercrime): Any illegal act involving a computer, including: Breaking through the security of a network Theft of financial assets Manipulating data for personal advantage Act of sabotage (releasing a computer virus, shutting down a Web server) All computer users should be aware of security issues and the precautions that can be taken Chapter 4 Understanding Computers in a Changing Society, 3 rd Edition 5
6 Unauthorized Access and Unauthorized Use Unauthorized access: Gaining access to a computer, network, file, or other resource without permission Unauthorized use: Using a computer resource for unapproved activities Both can be committed by insiders and outsiders Codes of conduct: Used to specify rules for behavior, typically by a business or school Chapter 4 Understanding Computers in a Changing Society, 3 rd Edition 6
7 Unauthorized Access and Unauthorized Use Hacking: The act of breaking into another computer system A serious threat for individuals, business, and the country (national security) Wi-Fi hacking: Common for hackers to gain entrance via Wi-Fi War driving or Wi-Fi piggybacking: Using someone else s Wi-Fi network to gain free access to the Internet Illegal in some areas Can lead to criminal behavior Ethical issues Chapter 4 Understanding Computers in a Changing Society, 3 rd Edition 7
8 Unauthorized Access and Unauthorized Use Interception of communications: Gaining unauthorized access to data as it is being sent over the Internet or another network The increased use of wireless networks has opened up new opportunities for data interception Business and personal wireless networks Use of public hotspots Wireless connections with mobile phones and mobile devices Once intercepted, the content can be read, altered, or otherwise used for unintended purposes Chapter 4 Understanding Computers in a Changing Society, 3 rd Edition 8
9 Computer Sabotage Computer sabotage: Acts of malicious destruction to a computer or computer resource Bot: A PC that is controlled by a computer criminal Botnet: A group of bots that can work together in a controlled fashion Used by botherders to send spam, launch Internet attacks and malware, etc. Malware: Any type of malicious software Includes viruses, worms, Trojan horses, etc. Increasingly used for computer crimes and to take control of individuals PCs for botnet activities Can infect mobile phones and mobile devices (some preinstalled on mobile devices) Chapter 4 Understanding Computers in a Changing Society, 3 rd Edition 9
10 Computer Sabotage Computer virus: Malicious program embedded in a file that is designed to cause harm to the computer system Often embedded in downloaded programs and messages Computer worm: Malicious program designed to spread rapidly by sending copies of itself to other computers Typically sent via Trojan horse: Malicious program that masquerades as something else Usually appear to be a game or other program Cannot replicate themselves; must be downloaded and installed Chapter 4 Understanding Computers in a Changing Society, 3 rd Edition 10
11 Computer Sabotage Chapter 4 Understanding Computers in a Changing Society, 3 rd Edition 11
12 Computer Sabotage Denial of service (DoS) attack: Act of sabotage that floods a Web server with so much activity that it is unable to function Distributed DoS attack: Uses multiple computers Chapter 4 Understanding Computers in a Changing Society, 3 rd Edition 12

20 Biometric Systems Chapter 4 Understanding Computers in a Changing Society, 3 rd Edition 20
21 Access Control Systems Controlling access to wireless networks In general, Wi-Fi is less secure than wired networks Security is usually off by default; wireless networks should be secured Wireless network owners should: Enable Wi-Fi encryption (WPA is more secure than WEP) Not broadcast the network name Change the default network administrator password Can use Media Access Control (MAC) address filtering Chapter 4 Understanding Computers in a Changing Society, 3 rd Edition 21
22 Controlling Access to Wireless Networks Chapter 4 Understanding Computers in a Changing Society, 3 rd Edition 22
