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






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






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






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






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






6. 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






7. 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






8. Detection - containment - eradication - recovery - reporting






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






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






11. 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






12. 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






13. Writing the same data on multiple hard disks






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






15. 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






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






17. 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






18. 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






19. 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






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






21. 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






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






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






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






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






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. Administrative control where employees are required to take a vacation. helps determine personnel single points of failure - detection and deterence of fraud - and the risk that comes with employees being unavailable for work. can also detect suspici






28. 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






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






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






31. Attacks against vulnerabilities with no patch or fix






32. 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






33. 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.






34. 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






35. 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






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






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






38. 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)






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






40. 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






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






42. 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






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






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






45. 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






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






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






48. A replica of all allocated data on a disk






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






50. 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
