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. Confidentiality - integrity - availability






2. Confidentiality - symmetric encryption






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






4. 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






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






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






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






8. 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






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






10. 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






11. 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






12. 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






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






14. An attacker recruits zombie systems ahead of time to simultaneously release a flood of traffic at a specific target.






15. 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






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






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






18. 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






19. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






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






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






22. -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






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






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






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






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






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






28. rules indicate criteria in packets that represent events of interest - rules are applied to packets as they are received - alerts are created when matches are found






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






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






31. 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






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






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






34. 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






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






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






37. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






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






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






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






41. Syn - Syn/Ack - Ack






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






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






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






45. 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






46. One is for talking - one is for implementing






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






48. Confidentiality - integrity - availability






49. 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






50. Uses a 1 to 1 substitution of characters - rotate the alphabet by 'n' number of characters - rot+X means rotate the letters X characters
