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






2. Writing the same data on multiple hard disks






3. 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.






4. 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






5. 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






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






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






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






9. 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






10. 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)






11. Denial of service - one to one availability attack






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






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






14. 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






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






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






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






18. 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






19. 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






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






21. Detection - containment - eradication - recovery - reporting






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






23. 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






24. 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






25. 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






26. 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






27. 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






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






29. 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






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






31. Most often associated with providing an attacker with persistent backdoor access. Trojans provide desirable functionality that the user is seeking but also come with malicious functionality that the user does not anticipate






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






33. 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






34. 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






35. 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






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






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






38. A replica of all allocated data on a disk






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






40. 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






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






42. 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






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






44. 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






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






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






47. 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






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






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






50. 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.
