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. 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






2. 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.






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






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. 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






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






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






8. 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






9. 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






10. 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






11. 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






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






13. 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






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






15. 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.






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






18. Detection - containment - eradication - recovery - reporting






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






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






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






22. 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






23. 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






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






25. 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






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






27. 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






28. 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






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






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






31. 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






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






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






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






35. 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






36. 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






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






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






39. Denial of service - one to one availability attack






40. 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






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






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






43. 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






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






45. Attacks against vulnerabilities with no patch or fix






46. 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.






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






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






49. 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






50. Writing the same data on multiple hard disks
