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 handles the establishment and maintenance of connections between systems






2. Known - unknown - zero day






3. 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






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






5. A cracking tool inserted into the OS that allows the attacker to do as they please.






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






7. Unencrypted message in its original form






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






9. 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






10. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






11. A list of files is defined that should be monitored for a change - HIDS software calculates a one-way hash for each file - if a change is made to the file - the hash is changed






12. Used by IDS for a baseline before analysis - attackers will try to de-normalize traffic to evade detection - IDS will normalize data for understood protocols






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






14. 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






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






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






17. Connection oriented - before systems can communicate over an ATM network - they must establish a virtual circuit between each other - this can span across multiple ATM switches that also handle communications for other systems - at the end of the con






18. 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






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






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






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






22. Going around with equipment to detect wireless networks






23. Message in its encrypted form






24. 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






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






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






27. Syn - Syn/Ack - Ack






28. 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






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






30. Trying to ID modems in a telephone exchange that may be susceptible to compromise






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






32. Most commonly used transport protocol today - ensures reliable packet delivery - has error handling built in






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






34. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






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






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






37. Strips OS commands and characters from input - avoid making system calls from within the app * especially based on user input






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






39. 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






40. rules indicate criteria in packets that represent events of interest - rules are applied to packets as they are received - alerts are created when matches are found






41. 1 and 2 - Voice/Low speed data - 3 - Voice/Data 10Mb - 4 - Voice/Data 16Mb - 5 - 5e - Voice/Data 100Mb to 1Gb - 6 - Standard for gigabit






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






43. Allows admins to remotely access a system for troubleshooting. - E.g VNC - GoToMyPc - PC Anywhere






44. Confidentiality - symmetric encryption






45. 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






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






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






48. OSI






49. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






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