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. A replica of all allocated data on a disk






2. 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






3. 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






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






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






6. 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






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






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






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






10. 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






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






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






13. 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






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






15. 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






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






17. 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






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






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






20. 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






21. 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.






22. 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.






23. 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






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






27. 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






28. 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






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






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






31. 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






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






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






35. 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






36. 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






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






38. 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






39. 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)






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






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






42. Detection - containment - eradication - recovery - reporting






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






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






46. 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






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






48. Attacks against vulnerabilities with no patch or fix






49. 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






50. 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.
