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






2. 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.






3. 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






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






5. 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






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. A replica of all allocated data on a disk






8. 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






9. 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






10. Detection - containment - eradication - recovery - reporting






11. 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






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






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






14. 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






15. 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






16. 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






17. 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






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






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






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






21. Writing the same data on multiple hard disks






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






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






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






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






26. 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.






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






28. 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)






29. 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






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






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






32. 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






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






34. 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






35. 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






36. 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






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






38. 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






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






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






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






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






43. 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






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






45. Denial of service - one to one availability attack






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






47. 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






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






49. 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






50. 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
