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. Denial of service - one to one availability attack






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






3. 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






4. 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






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






6. 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






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






9. Attacks against vulnerabilities with no patch or fix






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






11. 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)






12. 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






13. 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






14. Writing the same data on multiple hard disks






15. Detection - containment - eradication - recovery - reporting






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






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






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. 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






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






21. 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






22. 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






23. 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






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






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






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






27. 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






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






29. 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






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






31. 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.






32. 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






33. 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






34. 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






35. 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






36. A replica of all allocated data on a disk






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






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






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






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






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






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






43. 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.






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






45. 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






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






47. 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






48. 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






49. 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






50. 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
