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. 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






3. 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






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






5. 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






6. 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






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. 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






9. 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.






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. Writing the same data on multiple hard disks






12. 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






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






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






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






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






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






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






19. 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






20. 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






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






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






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






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






25. 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.






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






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






28. 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






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






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






31. 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.






32. 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






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






34. 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






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






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






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






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






39. 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






40. 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)






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






42. Denial of service - one to one availability attack






43. 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






44. 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






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






46. 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






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






48. 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






49. Attacks against vulnerabilities with no patch or fix






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