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 - 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






2. 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






3. 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






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






5. Writing the same data on multiple hard disks






6. Denial of service - one to one availability attack






7. 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)






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






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






10. 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






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






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






13. 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






14. 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






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






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






18. 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






19. 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






20. 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.






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






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






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






24. 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






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






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






27. Attacks against vulnerabilities with no patch or fix






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






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






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






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






32. 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






33. 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






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






35. 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.






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






37. 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.






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






39. 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






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






42. Detection - containment - eradication - recovery - reporting






43. 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






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






46. 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






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






48. 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






49. 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






50. 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
