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. Incident response stage in which a final report is presented to management. the goal is to detail ways in which the identification could have occurred sooner - the response could have been quicker or more effective - and organizational shortcomings t






2. 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






3. 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






4. 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






5. 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






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






7. Mirrored striped set with distributed parity (some manufacturers label this as RAID 53)






8. 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






9. Multi-raid - means that one standard RAID level is encapsulated within another.






10. 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






11. A replica of all allocated data on a disk






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






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






14. Backup of any files that have changed since the last backup






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






16. Administrative security control that prescribes that multiple people are required to complete critical or sensitive transactions. The goal is to ensure that in order for someone to be able to abuse their access to sensitive information or transaction






17. Incident response stage in which the response team attempts to keep further damage from occurring as a result of the incident. also the phase where a binary forensic backup is made of systems involved in the incident.






18. 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






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






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






21. 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






22. Writing the same data on multiple hard disks






23. Places the attacker between the victim and another system. the attackers goal is to be able to serve as an undiscovered proxy for either or both of two endpoints engaging in communication. Uses sniffing and spoofing. The capabilities of session hijac






24. 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






25. An offline technique in which the attacker has gained access to the password hashes or database






26. 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






27. 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






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






29. 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






30. Detection - containment - eradication - recovery - reporting






31. Trying all possible password combinations until a correct match between the hashes is found. may make use of rainbow tables which contain precomputed password-hash combinations






32. 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






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






34. Incident response stage in which the affected system(s) are restored to operational status. typically the business unit responsible for the system will dictate when the system will go back online. close monitoring is necessary






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






36. Data that persists beyond noninvasive means to delete it. sometimes used to refer to residual data that remains after sanitization takes place






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






38. The medium that allows the threat agent to exploit a vulnerability






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






40. OS - like the smurf attack - leverages a third party - the attacker who has poorly configured third party DNS servers queries an attacker controlled DNS server and cahce the response (the maximum size DNS response). Once the large record is cached by






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






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






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






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






45. 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.






46. 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






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






48. 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






49. 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






50. Introducing a magnetic field to magnetic storage media. a degausser destroys the integrity of the magnetization of the storage media - making the data unrecoverable
