What type of attack occurred? worm virus * Trojan horse denial of service 4) What is a major characteristic of a Worm? malicious software that copies itself into other executable programs tricks users into running the infected software a set of computer instructions that lies dormant until triggered by a specific event * exploits vulnerabilities with the intent of propagating itself across a network 5) A flood of packets with invalid source-IP addresses requests a connection on the network. The server busily tries to respond, resulting in valid requests being ignored. What type of attack occurred?

Only e-mail programs need to be protected. Only hard drives can be protected. * Only after a virus is known can an anti-virus update be created for it. Only computers with a direct Internet connection need it. 10) Which two statements are true concerning anti-spam software? (Choose two.) Anti-spam software can be loaded on either the end-user PC or the ISP server, but not both. * When anti-spam software is loaded, legitimate e-mail may be classified as spam by mistake. Installing anti-spam software should be a low priority on the network. * Even with anti-spam software installed, users should be careful when opening e- mail attachments. Virus warning e-mails that are not identified as spam via anti-spam software should be forwarded to other users immediately. 11) What term is used to describe a dedicated hardware device that provides firewall services? server-based integrated personal * appliance-based 12) Which acronym refers to an area of the network that is accessible by both internal, or trusted, as well as external, or untrusted, host devices? SPI * DMZ ISR ISP 13) Which statement is true about port forwarding within a Linksys integrated router? * Only external traffic that is destined for specific internal ports is permitted. All other traffic is denied. Only external traffic that is destined for specific internal ports is denied. All other

All other traffic is denied. Only internal traffic that is destined for specific external ports is denied. All other traffic is permitted. 14) To which part of the network does the wireless access point part of a Linksys integrated router connect? DMZ external * internal a network other than the wired network 15) Refer to the graphic. What is the purpose of the Internet Filter option of Filter IDENT (Port 113) on the Linksys integrated router? to require a user ID and password to access the router * to prevent outside intruders from attacking the router through the Internet to require a pre-programmed MAC address or IP address to access the router to disable tracking of internal IP addresses so they cannot be spoofed by outside devices 16) What statement is true about security configuration on a Linksys integrated router? A DMZ is not supported. The router is an example of a server-based firewall.
