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. 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






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






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. 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






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






7. 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






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






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






10. 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






11. A replica of all allocated data on a disk






12. 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






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






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






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






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






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






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






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






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






21. Writing the same data on multiple hard disks






22. 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






23. 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






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






25. 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






26. 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






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






28. 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.






29. 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






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






31. 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






32. 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






33. 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






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






35. 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






36. Denial of service - one to one availability attack






37. 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






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






40. 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






41. 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






42. 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






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






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






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






46. 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






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






48. 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.






49. 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






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