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. 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






2. 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






3. 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






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. 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. 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






7. 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






8. 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.






9. 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






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






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






12. 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






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






14. 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






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






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






17. Writing the same data on multiple hard disks






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






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






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






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






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






23. 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






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






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






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






27. Attacks against vulnerabilities with no patch or fix






28. A replica of all allocated data on a disk






29. 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






30. 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






31. 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






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






33. 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






34. 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






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






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






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






38. 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






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






40. Used to prevent an attack from being able to simply guess the correct password by attempting a large number of possibilities






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






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






43. 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






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






45. 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






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






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






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






49. Detection - containment - eradication - recovery - reporting






50. 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
