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. 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 its corresponding IP address






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






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






4. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






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






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






7. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






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






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






10. -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






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






12. 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






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






14. 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






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






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






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






18. One is for talking - one is for implementing






19. 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






20. It allows the transport layer to detect when the UDP headers or the payload have been modified in transit






21. Network scanner.






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






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






24. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






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






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






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






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






29. 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.






30. 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






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






32. Trivial File Transfer Protocol - method to transfer files from one device to another without needing authentication






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






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






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






36. 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.






37. Isolates systems when they initially connect to the network - allows systems to be scanned and checked prior to being put on a trusted segment






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






39. 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






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






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






42. Full open - half open (stealth scan) - UDP - Ping






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






44. Going around with equipment to detect wireless networks






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






46. Most common approach - firewall - VPN - intrusion detection - AV - disk encryption - all parts of the organization receive equal protection - particularly vulnerable to malicious inside attacks






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






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






49. 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






50. 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
