Q

This involves the implementation of standard operational security procedures that define the nature and frequency of the interaction between users, systems, and system resources, the purpose of which is to:
* achieve and sustain a known secure system state at all times, and
* prevent accidental or intentional theft, release, destruction, alteration, misuse, or sabotage of system resources.

Q

What level:
Desired Effects: to affect the technical performance and the capability of physical systems, to disrupt the capabilities of the defender.

Attacker’s Operations: physical attack and destruction, including: electromagnetic attack, visual spying, intrusion, scavenging and removal, wiretapping, interference, and eavesdropping.

Defender’s Operations: physical security, OPSEC, TEMPEST. Thus, IA includes aspects of COMPSEC, COMSEC, ITSEC, OPSEC

Q

The second level focus of IA is the ___________.

A

Information Infrastructure Level

22
Q

This covers information and data manipulation ability maintained in cyberspace, including: data structures, processes and programs, protocols, data content and databases.

A

Information Infrastructure Level

23
Q

What level:

Desired Effects: to influence the effectiveness and performance of information functions supporting perception, decision making, and control of physical processes.

Attacker’s Operations: impersonation, piggybacking, spoofing, network attacks, malware, authorization attacks, active misuse, and denial of service attacks.

Defender’s Operations: information security technical measures such as: encryption and key management, intrusion detection, anti-virus software, auditing, redundancy, firewalls, policies and standards.

A

Information Infrastructure Level

24
Q

The third level focus of IA is the _______, also called social engineering:

A

Perceptual level

25
Q

This is abstract and concerned with the management of perceptions of the target, particularly those persons making security decisions.

A

Perceptual level

26
Q

What level:

Desired Effects: to influence decisions and behaviors.

Attacker’s Operations: psychological operations such as: deception, blackmail, bribery and corruption, social engineering, trademark and copyright infringement, defamation, diplomacy, creating distrust.

Defender’s Operations: personnel security including psychological testing, education, and screening such as biometrics, watermarks, keys, passwords.

A

Perceptual level

27
Q

This is the flip side of Information Assurance. In fact, one can think of the offensive part of IW as ‘information operations,’ and the defensive part as ‘information assurance’.

A

Information Warfare (IW)

28
Q

This type involves managing an opponent’s perception through deception and psychological operations. In military circles, this is called Truth Projection.

A

Type I

29
Q

This type involves denying, destroying, degrading, or distorting the opponent’s information flows to disrupt their ability to carry out or co- ordinate operations.

A

Type II

30
Q

This type gathers intelligence by exploiting the opponent’s use of information systems.

A

Type III

31
Q

The offensive players in the world of IW come in six types:

A

Insiders
Hackers
Criminals
Corporations
Governments and agencies
Terrorists

32
Q

It consists of employees, former employees and contractors.

A

Insiders

33
Q

They are the one who gains unauthorized access to or breaks into information systems for thrills, challenge, power, or profit.

A

Hackers

34
Q

They target information that may be of value to them: bank accounts, credit card information, intellectual property, etc.

A

Criminals

35
Q

Those who actively seek intelligence about competitors or steal trade secrets.

A

Corporations

36
Q

Those who seek the military, diplomatic, and economic secrets of foreign governments, foreign corporations, and adversaries. May also target domestic adversaries.

A

Governments and agencies

37
Q

They are those who usually politically motivated and may seek to cause maximal damage to information infrastructure as well as endanger lives and property.

A

Terrorists

38
Q

True or False:
IA is both proactive and reactive involving: protection, detection, capability restoration, and response.

A

True

39
Q

True or False:
IA environment protection pillars: “ensure the availability, integrity, authenticity, confidentiality, and non-repudiation of information”

A

True

40
Q

: “timely attack detection and reporting is key to initiating the restoration and response processes.”

A

Attack detection

41
Q

: “relies on established procedures and mechanisms for prioritizing restoration of essential functions. Capability restoration may rely on backup or redundant links, information system components, or alternative means of information transfer.”

A

Capability restoration

42
Q

This is the resource being protected, including: physical assets: devices, computers, people; logical assets: information, data (in transmission, storage, or processing), and intellectual property; system assets: any software, hardware, data, administrative, physical, communications, or personnel resource within an information system.

A

Asset

43
Q

The items being protected by the system (documents, files, directories, databases, transactions, etc.)

A

Objects

44
Q

The entities (users, processes, etc.) that execute activities and request access to objects.

A

Subjects

45
Q

Operations, primitive or complex, that can operate on objects and must be controlled.

A

Actions

46
Q

Critical Aspects:
authorized users are able to access it;

A

Availability

47
Q

Critical Aspects:
the information is free of error and has the value expected;

A

Accuracy

48
Q

Critical Aspects:
the information is genuine;

A

authenticity

49
Q
