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. Known - unknown - zero day






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






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






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






5. 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






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






7. Unencrypted message in its original form






8. 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.






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






10. 53 bytes - 48 bytes for data - 5 bytes for the header






11. 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






12. 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






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






15. 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






16. 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






17. An attacker spoofs the victim's IP and sends an ICMP ECHO request to the broadcast address of a network. When every system responds - a DoS occurs.






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






19. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






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






21. 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






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






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






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






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






26. Confidentiality - integrity - availability






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






28. Hash Authentication - asymmetric - non repudiation - digital signature - hash + asymmetry






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






30. 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






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






32. Provides insight into the tactics - motives - and attacker tools






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






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






35. When someone has compromised the integrity of data or a program. Allows attackers to create backdoors.






36. True positive - false positive - true negative - false negative






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






38. 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






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






40. 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






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






42. Threat requires a vector to cross the vulnerability - stop the ability of the threat to use the vector






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






44. Resource exhaustion like DDoS or fork attack - unexpected input value the machine does not know how to process






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






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






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






48. Infected millions through various methods - vulnerability in the MS Server Service - brute force admin password through network shares - infect removable devices with a malicious autorun script






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






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