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. Two parties conspire to undermine the security of the transaction






2. 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






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






4. 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






5. 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.






6. 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






7. 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






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






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






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






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






12. 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






13. 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






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






15. 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






16. 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






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






18. 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)






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. 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






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






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






23. 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






24. Detection - containment - eradication - recovery - reporting






25. 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.






26. 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






27. 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






28. 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






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






30. 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






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






32. 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






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






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






35. 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






36. Denial of service - one to one availability attack






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






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






39. 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






40. A replica of all allocated data on a disk






41. Attacks against vulnerabilities with no patch or fix






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






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






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






45. 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






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






47. 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.






48. 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






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






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
