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






2. 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






3. Detection - containment - eradication - recovery - reporting






4. 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






5. 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






6. 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






7. 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






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






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






10. Writing the same data on multiple hard disks






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






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






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






15. 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






16. 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)






17. 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






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






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






20. Attacks against vulnerabilities with no patch or fix






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






22. A replica of all allocated data on a disk






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






24. 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.






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






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






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






28. 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






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






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






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






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






33. 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.






34. 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






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






36. 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






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






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






39. 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






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






41. 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






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






43. Denial of service - one to one availability attack






44. 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






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






46. 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






47. 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






48. 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






49. 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






50. 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
