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






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






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






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






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






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. 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. 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






9. 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






10. 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






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






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






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






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






15. 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






16. 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






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






18. 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






19. 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






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






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






23. A replica of all allocated data on a disk






24. Writing the same data on multiple hard disks






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






26. 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






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






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






29. 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






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






31. Denial of service - one to one availability attack






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






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






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






35. Detection - containment - eradication - recovery - reporting






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






37. 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






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






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






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






41. 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






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






43. 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






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. 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






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






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






48. 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






49. 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






50. 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
