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






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






3. 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






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






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


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






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






8. 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






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






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






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






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






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






14. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






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






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






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






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






19. 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






20. Confidentiality - integrity - availability






21. 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






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






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






24. 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






25. Metropolitan area network - spans across city or town - larger than a LAN - uses fiber for backbone






26. Confidentiality - symmetric encryption






27. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






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






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






30. Network scanner.






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






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






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






34. -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






35. Going around with equipment to detect wireless networks






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






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






38. Stateful firewalls maintain state of traffic flows






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






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






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






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






43. 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






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






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






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






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






48. Message in its encrypted form






49. 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






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