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






2. 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






3. 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






4. One is for talking - one is for implementing






5. 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






6. 1.0.0.0 through 127.255.255.255 - subnet mask starts at 255.0.0.0






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






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






9. 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






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






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






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






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






14. Protected at rest - protected in transit - secure the key






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






16. 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






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






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






19. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






20. Means multiple iterations won't matter. If you encrypt with a key - then re-encrypt - it's the same as using one key.






21. 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






22. Application layer attacks may get through - dialup - VPN - extranet connections may bypass firewalls






23. Infects MBR - no network spreading potential






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






25. OSI






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






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






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






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






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






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






32. Connection oriented - before systems can communicate over an ATM network - they must establish a virtual circuit between each other - this can span across multiple ATM switches that also handle communications for other systems - at the end of the con






33. 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






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






35. It interacts with data and prepares it to be transmitted across the network. It ensures reliable connectivity from end-to-end






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






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






38. Unencrypted message in its original form






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






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






41. 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






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






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






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






45. 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






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






47. 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






48. Wide Area Network - Larger than MAN or LAN - uses public network - phone lines - and leased lines to tie LAN and MAN over a dispersed area






49. 192.0.0.0 through 223.255.255.255 - subnet mask of 255.255.255.0






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