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. 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






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






3. OSI






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






5. Relies on executable code insertion and user interaction to spread






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






7. 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






8. removable media - email attachments - web browsing - social networking - network vulnerabilities - IM applications - p2p






9. An attempt to gain access by bombarding it with guesses until the password is found.






10. 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






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






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






13. Malware - insider threat - natural disaster - terrorism - pandemic






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






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






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






17. Network scanner.






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






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






20. 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






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






22. 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.






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






24. 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






25. FIN 130 - ACK 131 - FIN 570 - ACK 571






26. 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






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






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






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






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






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






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






33. Take the file and try to compress it. If it compresses - it means there is a pattern and it's more easily crackable

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






35. One is for talking - one is for implementing






36. 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






37. 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






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






39. 53 bytes - 48 bytes for data - 5 bytes for the header






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






41. Going around with equipment to detect wireless networks






42. 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






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






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






45. Publish separate mail - web - and DNS servers to the internet - provide appropriate access from internal network to internet - protect internal from external attack - provide defense in depth - protect all aspects of the system






46. -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






47. Connects the physical part of the network (cables) with the abstract (packets and datastreams)






48. It handles the establishment and maintenance of connections between systems






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






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