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. 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






2. 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.






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






4. Physical layer - Data link layer - Network Layer - Transport Layer - Session Layer - Presentation Layer - Application Layer






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






6. Going around with equipment to detect wireless networks






7. 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






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






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






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






11. An agreement on how different computer will work - protocols define the format and order of messages and what to do upon receipt of the messages - basically the rules of the network






12. 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






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






14. Confidentiality - integrity - availability






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






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






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






18. -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






19. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






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






21. 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






22. Infects MBR - no network spreading potential






23. logic bomb - trojan horse - trap door






24. 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






25. Worms and Wireless - modems - tunnel anything through HTTP - social engineering






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






27. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






28. local area network - small network confined to small location - all equipment owned by a single entity - vulnerable to inside threats and logic bombs






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






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






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






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






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






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






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






36. Prepends to the beginning of the file and gains control when the first instruction of the infected COM file is executed - appending to the end - virus writes its payload to the end and inserts jump instruction as the first instruction - which execute






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






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






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






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






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






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






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






44. 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






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






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






47. 53 bytes - 48 bytes for data - 5 bytes for the header






48. Network scanner.






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






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