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






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






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






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






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






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






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






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






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






10. 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






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






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






14. 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






15. 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






16. Infects MBR - no network spreading potential






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






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






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






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






21. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






22. logic bomb - trojan horse - trap door






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






24. 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.






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






26. 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






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. Simple attack done by simply browsing available information that's allowed on a local network.






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






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






32. 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






33. 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






34. 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






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






36. Slow - requires stateful data tracking - inspects all fields - including variable-length fields






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






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






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

40. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






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






42. -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






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






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. Confidentiality - integrity - availability






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






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






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






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






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