CISSP Operational Security

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. Malicious code that hooks onto executable code - and requires user interaction to spread. In addition to spreading - the actual payload of the virus - that is - what it is intended to do - could be anything






2. Administrative control - a work related contractual agreement that ensures that employees - prior to being given sensitive information - will maintain the confidentiality and sensitivity of this information (also considered a directive control)






3. Confidentiality attack on network traffic - involves monitoring packets as they traverse a network.






4. An administrative security control that dictates a person should have no more access that the access that is strictly required to perform their job






5. DOS - malformed packet - the teardrop attack is a malformed packet attack that targets issues with systems fragmentation reassembly. The attack involves sending packets with overlapping fragment offsets - which can cause a system attempting to reasse






6. Striped set with dual distributed parity - allows for recovery if two disks fail






7. Striped set with dedicated parity at the byte level - data at the byte level is striped across multiple disks - but an additional disk is leveraged for storage of parity information - which is used for recovery in the event of a failure. allows for d






8. Masquerading as another endpoint. presenting false information - usually within packets - to trick other systems and hide the origin of the message. done to prevent an identity from becoming uncovered






9. Redundant array of inexpensive disks - goal is to mitigate the risk of failure of a hard disk






10. Incident response stage in which the process of understanding the cause of the incident so that the system can be readily cleaned and ultimately restored.






11. Any type of software that attacks a system or application - also called malicious code






12. A means to achieve data redundancy without incurring the same degree of cost as that of mirroring in terms of disk usage and write performance






13. Striped set - offers no data redundancy and is a poor choice if recovery of data is the reason for leveraging RAID






14. Incident response stage in which events are analyzed in order to determine whether these events might comprise a security incident. is the event occurring or has it occurred






15. Distributed denial of service - many to one availability attack






16. Writing the same data on multiple hard disks






17. DOS - resource exhaustion - most basic type of resource exhaustive attacks - and involve an attacker - or attacker controlled machines - initiating many connections to the victim - but not responding to the victim's SYN/ACK packets. The victim's conn






18. Administrative control where employees are required to take a vacation. helps determine personnel single points of failure - detection and deterence of fraud - and the risk that comes with employees being unavailable for work. can also detect suspici






19. Process: identify a change - propose a change - assess the risk associated with the change - test - schedule the change - notify impacted parties - implement - report the results to management - all changes must be tracked and auditable - a detailed






20. Administrative control that makes sure employees have the proper rights and privileges to perform their work. escalation of priviliges can occur as employees are promoted or change jobs - yet their access rights and priveleges to systems and informat






21. Considered the most secure means of data sanititzation - commonly uses incineration or pulverization






22. Striped sets in a mirrored set (minimum four disks; even number of disks) provides fault tolerance and improved performance but increases complexity. The key difference from RAID 1+0 is that RAID 0+1 creates a second striped set to mirror a primary s






23. DOS - resource exhaustion - involves ICMP flooding. The attacker sends ICMP echo request messages with spoofed source addresses of the victim to the directed broadcast address of a network known to be smurf amplifier. As with most resource exhaustive






24. Mirrored sets in a striped set (minimum four disks; even number of disks) provides fault tolerance and improved performance but increases complexity.






25. Mirrored set - creates an exact duplicate of all data to an additional disk. allows for data recovery in the event that n-1 disk fails






26. Means load balancing - each node in a HA cluster is actively processing data prior to failure






27. Define a minimum reporting threshold level and help differentiate an attack from noise - but can also cause false negatives






28. Administrative control where in order to mitigate risk and uncover potential fraud - employee's job or job functions are shifted and changed






29. A hot standy - configuration in which the backup systems only begin processing when a failure state is detected






30. Administrative security control used in MAC systems where access determination is based upon a clearance level of subjects and classification levels of objects. Compartmentalization enforces need to know which necessitates that someone requires acces






31. Deleting the file allocation on a storage device. important in security because it does not delete the data - it merely deletes the points that are used to find the data






32. Dictionary attacks - directs the password cracking tool to use a supplied list of words as potential passwords.






33. DOS - resource exhaustion - a variation of the smurf attack - the main difference being that fraggle leverages UDP for the request portion - and stimulates an ICMP port unreachable message being sent to he victim rather than an ICMP echo response






34. DOS - malformed packet - the land attack uses spoofed SYN packet that includes the victim's IP address and TCP port as both source and destination. This attack targets the TCPIP stack






35. Uses the dictionary attack but makes alterations to the word before putting the guess through the hashing algorithm






36. An online technique that involves attempting to authenticate a particular user to a system






37. Administrative control - the sensitivity of the position being filled largely determines the extent to which this control is used. Try to uncover any information that may indicate a prospective employee will be unable to perform their job






38. Back up any files that had changed since the last full backup






39. Failover cluster - employs multiple systems that are already installed - configured - and plugged in - such that if a failover causes one of the systems to fail - then the other can be seamlessly leveraged to maintain the availability of the service






40. Two parties conspire to undermine the security of the transaction






41. Spreading data across multiple hard disks. increases performance and does create data redundancy






42. Malicious code that infects Microsoft Office documents by means of embedding malicious macros within them.






43. Striped set with distributed parity - uses block level striping - writes parity information that is used for recovery purposes. distributes the parity information across multiple disks. allows for data recovery in the event that one disk fails






44. Striped set with dedicated parity at the block level - employs a dedicated parity drive rather than having parity data distributed amongst all disks. allows for data recovery in the event that one disk fails






45. The actors causing the threats that might exploit a vulnerability






46. More effective data sanitization technique where data on a drive is overwritten






47. Denial of service - one to one availability attack






48. Detection - containment - eradication - recovery - reporting






49. Term used for malware that is focused on hiding its own existence. Typical capabilities include file - folder - process - and network connection hiding. The techniques developed with rootkits are now commonly included in other types of malware






50. Have the ability to self-propogate - or spread without user interaction. more well known worms: Code Red - Nimda - SQL Slammer - Blaster - MyDoom - Witty
