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. Protected at rest - protected in transit - secure the key






2. logic bomb - trojan horse - trap door






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






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






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






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






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






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






10. 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






11. Anonymous FTP - FTP passes through clear text - Bounce attacks with the PORT command - user can cause an FTP to open a connection from the FTP's own commands and bypass a firewall






12. OSI






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

14. Very simplistic. All systems are attached to the same cable segment. Rarely used because they're unreliable - low fault tolerance - poor traffic isolation - with limited scalability






15. Known - unknown - zero day






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






17. 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






18. 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






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






20. Good for multimedia - can use small single packets - multicasting is required - speed is the highest priority






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






22. 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.






23. Attempt to manipulate or trick a person into providing information or access - bypass network security by exploiting humans - vector is often outside attack by telephone or visitor inside






24. Confidentiality - integrity - availability






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






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






27. 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






28. True positive - false positive - true negative - false negative






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 it's corresponding IP address






30. -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






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






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






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






34. UDP based infection - infected through vulnerability in SQL server - caused DoS on saturated networks






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






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






37. 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






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






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






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






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






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






43. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






44. 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






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. 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.






47. Syn - Syn/Ack - Ack






48. destruction of data - leaking confidential information - providing backdoor access






49. 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






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