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. 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






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. 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






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






6. 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






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






8. 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






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






10. Denial of service - one to one availability attack






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






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






13. 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






14. 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






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






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






18. 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






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






20. 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






21. 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






22. 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






23. 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)






24. 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






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






26. 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.






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






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






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






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






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






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






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






36. 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.






37. 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






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






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






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






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






42. 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






43. 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






44. Attacks against vulnerabilities with no patch or fix






45. 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






46. 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






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






48. 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






49. 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






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