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






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






3. 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






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






5. 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






6. 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






7. 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






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. 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






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. 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.






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






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






14. 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






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






16. Denial of service - one to one availability attack






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






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






19. 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






20. 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






21. 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






22. 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






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






24. 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






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






26. 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






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






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






29. 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






30. 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






31. 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






32. 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






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






34. 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






35. 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)






36. 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






37. 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






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






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






40. A replica of all allocated data on a disk






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






42. Striped set with dual distributed parity - allows for recovery if two disks fail






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






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






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






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






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






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






49. 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






50. Detection - containment - eradication - recovery - reporting
