Chapter 8 Securing Information Systems
1) A drive-by download is a technique used by hackers to enable accessing files on a wireless
network.
2) Computers using cable modems to connect to the Internet are more open to penetration than
those connecting via dial-up.
3) Wireless networks are vulnerable to penetration because radio frequency bands are easy to
scan.
4) Mobile devices are not targeted as extensively by malware as traditional computers.
5) A Trojan horse is a software program that appears to be benign but then does something
other than expected.
