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. Detection - containment - eradication - recovery - reporting






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






3. 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






4. 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






5. 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






6. 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






7. 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






8. 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






9. 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






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






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






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






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






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






15. 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






16. Denial of service - one to one availability attack






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






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






19. A replica of all allocated data on a disk






20. 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






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






22. 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.






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






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






25. 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






26. Writing the same data on multiple hard disks






27. 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






28. 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






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






30. 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.






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






32. 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






33. Attacks against vulnerabilities with no patch or fix






34. 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






35. 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






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






37. 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






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






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






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






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






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






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






44. 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






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






46. 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






47. 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






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






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






50. 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
