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. 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






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






3. 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






4. 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.






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






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






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






8. Detection - containment - eradication - recovery - reporting






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






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






11. Denial of service - one to one availability attack






12. 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






13. 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






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






15. 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






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






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






18. A replica of all allocated data on a disk






19. 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.






20. 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






21. 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






22. 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






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






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






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






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






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






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






29. 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






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






31. 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






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






33. 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






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






35. 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






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






37. Attacks against vulnerabilities with no patch or fix






38. 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






39. 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






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






41. 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






42. 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






43. 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






44. 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






45. Writing the same data on multiple hard disks






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






47. 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






48. 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)






49. 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.






50. 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
