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






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






4. 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.






5. 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






6. 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






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






8. 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






9. 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






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






11. 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






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






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






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






15. 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.






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






17. 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






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






19. 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






20. 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






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. 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






23. 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






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






25. 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






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






27. 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






28. 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






29. Denial of service - one to one availability attack






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






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






34. 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






35. 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






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






37. 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






38. 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






39. 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






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






41. Writing the same data on multiple hard disks






42. 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






43. 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






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






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






46. 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






47. 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)






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






49. 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






50. A replica of all allocated data on a disk
