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






2. 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






3. Denial of service - one to one availability attack






4. Detection - containment - eradication - recovery - reporting






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






6. 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






7. 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






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






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






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






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






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






13. 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






14. 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






15. 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






16. 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






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






18. 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






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






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






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






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






23. 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.






24. 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






25. 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






26. 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






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






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






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






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






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






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






33. 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






34. 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






35. Attacks against vulnerabilities with no patch or fix






36. 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






37. 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






38. 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






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






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






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






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






43. 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






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






45. 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)






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






47. 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






48. 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






49. 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






50. 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
