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. 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






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






3. 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






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






5. 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)






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






7. 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






8. 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






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






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






11. 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






12. 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






13. 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






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






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






16. 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






17. 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






18. 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






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






20. A replica of all allocated data on a disk






21. 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






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






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






24. Attacks against vulnerabilities with no patch or fix






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






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






27. 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






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






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






30. 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






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






32. Detection - containment - eradication - recovery - reporting






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






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






35. 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






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






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






38. 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






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






40. 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






41. 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






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






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






46. Denial of service - one to one availability attack






47. 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






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






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. 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.
