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. 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






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






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






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






5. 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






6. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






7. 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.






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






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






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






11. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






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






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






14. War dialing - war driving - Sniffing - eavesdropping - dumpster diving - social engineering






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






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






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






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






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






20. 1. physical 2. data 3. network 4. transport 5. session 6. presentation 7. application






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






22. 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






23. Physical layer - Data link layer - Network Layer - Transport Layer - Session Layer - Presentation Layer - Application Layer






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






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






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






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






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






29. 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






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






31. 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






32. Infects MBR - no network spreading potential






33. Very simplistic. All systems are attached to the same cable segment. Rarely used because they're unreliable - low fault tolerance - poor traffic isolation - with limited scalability






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






35. 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.






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






37. 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






38. An attacker spoofs the victim's IP and sends an ICMP ECHO request to the broadcast address of a network. When every system responds - a DoS occurs.






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






40. Stateful firewalls maintain state of traffic flows






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






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






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






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






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






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. Confidentiality - symmetric encryption






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






49. Going around with equipment to detect wireless networks






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