Test your basic knowledge |

Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Netmasks or subnets provide a method for identifying what portion of an address is the network - and what portion is the host






2. Replicates traffic onto all ports - no traffic monitoring - cannot control which ports should or shouldn't receive frames - forming a large collision domain.






3. Metropolitan area network - spans across city or town - larger than a LAN - uses fiber for backbone






4. Attacks systems through known vulnerabilities - automatically scans for more systems to attack - lowers system defenses - installs rootkit or root shell - opens up back doors - self contained malware that can copy itself






5. Syn - Syn/Ack - Ack






6. Small program triggered by an event that provides an action. E.g. scheduled file removal if countdown isn't reset - ie: employee was fired






7. The practice of sending an ACK inside another packet going to the same destination






8. Protected at rest - protected in transit - secure the key






9. Protects internal/external systems from attack - filters communications based on content - performs NAT - encrypts communications for VPN - logging to aid in intrusion detection






10. An attacker spoofs the victim's IP and sends an ICMP ECHO request to the broadcast address of a network. When every system responds - a DoS occurs.






11. Full open - half open (stealth scan) - UDP - Ping






12. An FTP that allows downloads only if the user knows the exact name of the file they're looking for






13. A TCP version of ping - sends custom TCP packets to a host and listens for replies - enables port scanning and spoofing simultaneously






14. free windows based wireless scanner for 802.1b - detects access point settings - supports GSP integration - identifies networks as encrypted or unencrypted






15. Uses a 1 to 1 substitution of characters - rotate the alphabet by 'n' number of characters - rot+X means rotate the letters X characters






16. Simple attack done by simply browsing available information that's allowed on a local network.






17. Handles the network address scheme and connectivity of multiple network segments. It handles communication.






18. It allows the transport layer to detect when the UDP headers or the payload have been modified in transit






19. Migrate to WPA2 - use strong authentication like PEAP or TTLS - audit network installations - require mutual auth between client and infrastructure equipment






20. Trivial File Transfer Protocol - method to transfer files from one device to another without needing authentication






21. flags anomalous conditions in traffic on the network - requires understanding on what is normal - bases good traffic as a baseline






22. risk = threat x vulnerability - impossible to eliminate - security is an exercise in loss reduction






23. Personal area network - phone tethering - bluetooth - etc






24. Used for connecting two physical segments of a network - segments traffic - breaks up collision domains - not generally used because of switches






25. Multiple levels of protection must be deployed - an exercie in detection - measures must be across a wide range of controls - compromises happen when people leave sites - risk - CIA triad - strategies






26. Provides insight into the tactics - motives - and attacker tools






27. TCP/IP - the IP protoco - The core routing protocol of the internet - - deals with transmission of packets between end points - defines the addressing scheme for the internet






28. Switches along the path can be requested to allocate the desired amount of bandwidth. If the circuit has the required bandwidth - the circuit is set up.






29. Network traffic to the host - typically listens on all interface - uses signature analysis to identify events of interest






30. It interacts with data and prepares it to be transmitted across the network. It ensures reliable connectivity from end-to-end






31. low interaction production honeypot - network daemon that can simulate other hosts - each host can appear as a different OS






32. Not a replacement for firewalls - hardening - strong policies - or other DiD methods - low maintenance - inexpensive






33. A time of check/time of use attack that exploits the difference in between when a security control was applied and the time the service was used.






34. Free linux WLAN analysis tool - completely passive - cannot be detected - supports advanced GPS integration and mapping features - used for wardriving - WLAN vulerability assessment






35. An appliance that controls access between public internet and a companies private network - or between a PC NIC and the rest of the PC.






36. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






37. Infected millions through various methods - vulnerability in the MS Server Service - brute force admin password through network shares - infect removable devices with a malicious autorun script






38. 1. physical 2. data 3. network 4. transport 5. session 6. presentation 7. application






39. Improper deployment can increase attack risk - if production systems aren't sufficiently protected - they can be vulnerable from a honeypot - legal liability






40. Bits of code embedded in programs to quickly gain access at a later time






41. Resource exhaustion like DDoS or fork attack - unexpected input value the machine does not know how to process






42. War dialing - war driving - Sniffing - eavesdropping - dumpster diving - social engineering






43. ATM supports two types of virtual circuits: permanent virtual circuits and switches virtual circuit - PVC is set up in advance - usually manually - SVC is established automatically through a signaling protocol and can be created on the fly - establis






44. packet filter firewalls rely on TCP flags to determine connection state. Attacker can send ACK packets only to bypass firewall.






45. Uses inclusive or exclusive lists - inclusive analysis utilizes a list of keywords - exclusive analysis utilizes a list of events that can be ignored






46. Attempt to manipulate or trick a person into providing information or access - bypass network security by exploiting humans - vector is often outside attack by telephone or visitor inside






47. A spoofed IP is used to send a SYN to the target. It then responds with a SYN/ACK that never receives the final ACK to complete the handshake. This occupies a portion of the target's pre-established buffer for TCP and can prevent the target from acce






48. Means multiple iterations won't matter. If you encrypt with a key - then re-encrypt - it's the same as using one key.






49. A sends a SYN packet to B - B acknowledges with a SYN/ACK - A replies with ACK






50. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0
