2. 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






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






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






5. Message in its encrypted form






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






7. 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






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






9. 128.0.0.0 through 191.255.255.255 - with a subnet mask of 255.255.0.0






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






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






13. Considered to be a perimeter device






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






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






16. Confidentiality - symmetric encryption






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






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






19. 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






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






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






22. 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






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






24. Allows segmentation of a switch into different networks - regardless of where a system is plugged in - creates separate networks through software not hardware

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






26. 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.






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






28. 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






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






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






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






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






33. 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






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






35. Migrate to WPA2 - use strong authentication like PEAP or TTLS - audit network installations - require mutual auth between client and infrastructure equipment






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






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






38. 8 bytes per packet - UDP SRC port - UDP DST Ports - UDP length - UDP Checksum






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

40. Syn - Syn/Ack - Ack






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