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. open source tool for monitoring - can be used as a NIDS - has quick updates and flexibility for custom rules






2. Syn - Syn/Ack - Ack






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






4. logic bomb - trojan horse - trap door






5. OSI






6. Confidentiality - integrity - availability






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






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






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






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






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






12. 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






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






14. CIDR is a shorthand way of specifying which portion of the address is the network - and which portion is the host






15. Outside attack from network - Outsider attack from telephone - Insider attack from local network - insider attack from local system - attack from malicious code






16. Considered to be a perimeter device






17. deployment challenges including topology and access limitations - analyzing encrypted traffic - quantity vs. quality of signatures - performance limitations with extensive analysis techniques - very costly for proper management






18. keeps the same letters - but changes the position within the text - easy to break - can be combined with substitution






19. Not frequently seen on LANs because of expense - because of its traffic predictability and high bandwidth support - it's good for video streaming - encapsulates common protocols - uses virtual path identifiers to create end to end connectivity - has






20. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






21. An attacker recruits zombie systems ahead of time to simultaneously release a flood of traffic at a specific target.






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






23. Program disguised as something helpful - only to perform actions the user did not intend. Opening ports - installing other programs - etc.






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






25. 53 - DNS - 67 - BootP - 68 - BootP - 69 - TFTP - 123- NTP - 137-139 NBT - 161 - SNMP - 162 - SNMP - 2049 - NFS






26. Poor programming without error checking can allow commands to be run in an input field. This can point to a command further in the buffer that will execute the attacker's payload.






27. Most common approach - firewall - VPN - intrusion detection - AV - disk encryption - all parts of the organization receive equal protection - particularly vulnerable to malicious inside attacks






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. Application layer attacks may get through - dialup - VPN - extranet connections may bypass firewalls






30. Intrusion detection system - it reports attacks against monitored systems/networks






31. Unified data carrying service - replacing from replay and ATM






32. Simplest form of a research honeypot - useful in identifying nature of TCP scans - allows attacker to complete 3-way handshake - listens on a defined port - logs incoming requests for analysis






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






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






35. Attaches itself to existing program files and activated when the exe is launched






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






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






38. Wide Area Network - Larger than MAN or LAN - uses public network - phone lines - and leased lines to tie LAN and MAN over a dispersed area






39. Spread as an office attachment with executable code programmed using macro facility - targets are data files - visual basic editor and other macro languages - payload executes when the code is launched






40. A system resource that has no legitimate purpose or reason for someone to connect to it - its purpose is to draw in attackers to understand how they break into a system






41. Identify critical assets and provide layered protection - data is accessed by applications - applications reside on hosts - hosts operate on networks






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






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






44. Parasitic malware - boot record infector - macro - COM/Script program infector - EXE program infector






45. Infects the EXE and make them operate slightly different - when infected - exe header sizes are altered to point to the appended viral code






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






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






48. A low end firewall that can quickly be deployed using existing hardware. They examine packets themselves with no content.






49. 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






50. Uses flow control to handle network congestion - can send larger amounts of data per packet - has guaranteed delivery of transmitted data - better protection against spoofing - reduces need for error checking at higher OSI layers
