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






2. 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






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






4. 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






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






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






7. 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






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






9. Denial of service - one to one availability attack






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






11. 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






12. 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






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






14. A replica of all allocated data on a disk






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






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






17. Writing the same data on multiple hard disks






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






19. 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






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






21. 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






22. 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






23. Detection - containment - eradication - recovery - reporting






24. 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






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






26. 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)






27. 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






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






29. 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.






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






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. Stipulate all expectations regarding the providing of a service and its quality. what is considered acceptable regarding things such as bandwidth - time to delivery - response time - etc.






33. 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






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






35. 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






36. 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






37. 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






38. 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






39. 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






40. 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.






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






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






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






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






45. 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






46. 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






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






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






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






50. 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
