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






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






3. 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






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






5. 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






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






7. 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.






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






9. A replica of all allocated data on a disk






10. 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






11. 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






12. 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






13. 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






14. 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.






15. 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






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






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






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






19. 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






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






21. 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






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






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






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






25. 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






26. Denial of service - one to one availability attack






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






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






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






30. Detection - containment - eradication - recovery - reporting






31. 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






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






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






34. 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






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






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






37. 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






38. 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.






39. 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






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. 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






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






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






44. 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






45. 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






46. Writing the same data on multiple hard disks






47. 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






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