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. It makes sure the data sent from one side to the other is in a format useful to the other side






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






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






4. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






5. Confidentiality - integrity - availability






6. Switches networks make it difficult to monitor traffic in promiscuous mode - topology must be able to support traffic aggregation for monitoring






7. fast - with little fidelity - examines header information and limited payload data






8. Hash Authentication - asymmetric - non repudiation - digital signature - hash + asymmetry






9. 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






10. Maintains complete TCP connection state and sequencing through 2 connections - address translation built-in by virtue of second connection above






11. 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.






12. Slow - requires stateful data tracking - inspects all fields - including variable-length fields






13. Going around with equipment to detect wireless networks






14. Netmasks or subnets provide a method for identifying what portion of an address is the network - and what portion is the host






15. Connects many WANs - MANs - and LANs - provided via ISP






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






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






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






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






20. Provides insight into traffic on the network - help detect problems with network operations - provides auditing for other security measures






21. Combines the functionality of a hub and bride into a single device - keeps track of MACs attached to each port






22. The Practice of sending an ACK inside another packet going to the same destination






23. -Malicious code might execute destructive overwrite to hard disks -Malicious mas mailing code might expose sensitive information to the internet - web server compromise might expose organization to ridicule - Web server compromise might expose custom






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






25. Threat requires a vector to cross the vulnerability - stop the ability of the threat to use the vector






26. Known - unknown - zero day






27. Weakness in a system - inherent in a complex system - majority are due to poor coding - gateway by which threats are manifested






28. size is whatever the length of the UDP portion of the packet. Could be as large as 65 -535






29. Protocol for mapping an IP address to a physical machine address that is recognized on the local network. A table - usually called the ARP cache - is used to maintain a correlation between each MAC and its corresponding IP address






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






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






32. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






33. Intellectual property - business goals - validated data - historical






34. Uniform protection - protected enclaves - information centric - threat vector analysis






35. 53 - DNS - 67 - BootP - 68 - BootP - 69 - TFTP - 123- NTP - 137-139 NBT - 161 - SNMP - 162 - SNMP - 2049 - NFS






36. 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.






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






38. Four layers - Network Layer - Internet Layer - Transport Layer - Application layer






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






40. NTP - BootP/DHCP - NFS file systems - SNMP - TFTP






41. 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






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






43. A hash is produced when applied to a monitored file. The hash always generates the same value unless a change was made. HIDS software checks the hashes of monitored files and if a change is found - analyst is notified. - ie: tripwire






44. Uses a 1 to 1 substitution of arbitrary numbers - given a one character mapping - you cannot determine the key






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






46. 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






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






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






49. True positive - false positive - true negative - false negative






50. Work groups that require additional protection are segmented from the rest of the internal organization - restricting access to critical segments - system of VPNs - internal firewall - VLANs and ACLs
