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






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






3. size is whatever the length of the UDP portion of the packet. Could be as large as 65 -535






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






5. Trying to ID modems in a telephone exchange that may be susceptible to compromise






6. Common backdoor to open a port - port scan scans for open ports on remote host - scans 0 - 65 -535 twice. TCP and UDP






7. 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






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






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






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






11. Allows admins to remotely access a system for troubleshooting. - E.g VNC - GoToMyPc - PC Anywhere






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






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






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






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






16. 20 - FTP data - 21 - FTP - 23 - Telnet - 25 - SNMP - 53 - DNS - 79 - Finger - 80 - HTTP - 110 - POP - 443 - HTTPS






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






18. Intrusion detection system - it reports attacks against monitored systems/networks






19. A spoofed IP is used to send a SYN to the target. It then responds with a SYN/ACK that never receives the final ACK to complete the handshake. This occupies a portion of the target's pre-established buffer for TCP and can prevent the target from acce






20. Syn - Syn/Ack - Ack






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






22. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






23. 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






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






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






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






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






28. Infects MBR - no network spreading potential






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






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






31. Handles transmissions across the physical media like wires - fiber - etc






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






33. Confidentiality - integrity - availability






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






35. -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






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






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






38. 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






39. 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






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






41. 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






42. 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






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






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






45. flags anomalous conditions in traffic on the network - requires understanding on what is normal - bases good traffic as a baseline






46. Stateful firewalls maintain state of traffic flows






47. Network scanner.






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






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






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