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. 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






2. Denial of service - one to one availability attack






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






4. 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






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






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






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






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






10. 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






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






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. 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






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






15. 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)






16. 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






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






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






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






20. 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






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






22. 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.






23. 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






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






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






26. 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






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






28. 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






29. 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






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






31. 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






32. Detection - containment - eradication - recovery - reporting






33. A replica of all allocated data on a disk






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






35. DOS - Malformed packet - denial of service involved in sending a malformed ICMP echo request (ping) that was larger than the maximum size of an IP packet. Patching TCPIP stacks of systems removed the vulnerability of this DOS attack






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






37. 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.






38. 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






39. Writing the same data on multiple hard disks






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






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






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






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






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






45. 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






46. Attacks against vulnerabilities with no patch or fix






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






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






49. 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






50. 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
