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 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






2. 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






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






4. 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






5. 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






6. 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






7. 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






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






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






10. Writing the same data on multiple hard disks






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






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






13. Attacks against vulnerabilities with no patch or fix






14. 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.






15. 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






16. 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






17. 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






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






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






20. 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






21. 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.






22. Detection - containment - eradication - recovery - reporting






23. 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






24. 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






25. 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






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






27. 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






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






29. A replica of all allocated data on a disk






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






31. 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






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






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






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






35. 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






36. 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






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






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






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






40. 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






41. 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






42. Denial of service - one to one availability attack






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






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. 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






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






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






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






49. 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)






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