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. 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.






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






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






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






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






6. 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






7. 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






8. 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






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






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






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






12. 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






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






14. 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






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






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






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






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






19. 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






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






21. 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






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






23. A replica of all allocated data on a disk






24. 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






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






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






27. 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






28. 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.






29. 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






30. 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)






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






32. 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






33. 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






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






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






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






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






38. 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






39. 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






40. 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






41. 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






42. 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






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






44. 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






45. Denial of service - one to one availability attack






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






47. 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






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






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






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