The 1990s
Networks of computers became more common; so too did the need to interconnect networks
Internet became first manifestation of a global network of networks
In early Internet deployments, security was treated as a low priority
![Page 17: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/17.jpg)
2000 to Present
The Internet brings millions of computer networks into communication with each other—many of them unsecured
Ability to secure a computer’s data influenced by the security of every computer to which it is connected
Growing threat of cyber attacks has increased the need for improved security

Introduction
The concept of computer security has become synonymous with the concept of information security
Information security is no longer the sole responsibility of a discrete group of people in the company
![Page 19: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/19.jpg)

What Is Security?
• How do you define security?
• Specialized areas of security• Physical• Operations• Communications• Network
Each of these areas contribute to the information security program as a whole

CNSS Security Model (cont’d.)
C.I.A. triangle – Confidentiality, integrity, and availability – Has expanded into a more comprehensive list of
critical characteristics of information
NSTISSC (CNSS) Security Model – Provides a more detailed perspective on security– Covers the three dimensions of information security– Primary purpose: identify gaps in the coverage of
an information security program
![Page 26: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/26.jpg)
CNSS Security Model (cont’d.)
NSTISSC Security Model (cont’d.)– Must address all 27 cells when
designing/reviewing a program
Main Purpose: identify gaps in an information security program

How to measure the value of information - CIA Triangle
IdentificationAuthentication AuthorizationPrivacyAccountability
Expanded toinclude
The value of information comes from the characteristics it possesses
![Page 28: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/28.jpg)
Confidentiality
The characteristic of information whereby only those with sufficient privileges may access certain information
Measures used to protect confidentiality:– Information classification– Secure document storage– Application of general security policies– Education of information custodians and end users
![Page 29: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/29.jpg)
Integrity
The quality or state of being whole, complete, and uncorrupted
Threats to information integrity:– Corruption– Damage– Destruction– Other disruption of its authentic state
![Page 30: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/30.jpg)
Availability
The characteristic of information that enables user access to information in a required format, without interference or obstruction
Availability does not imply that the information is accessible to any user (Implies availability to authorized users)
![Page 31: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/31.jpg)
Identification and Authentication
Identification– An information system possesses the characteristic
of identification when it is able to recognize individual users
– Identification and authentication are essential to establishing the level of access or authorization that an individual is granted
Authentication – Occurs when a control proves that a user possesses
the identity that he or she claims
![Page 32: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/32.jpg)
Authorization
Assures that the user has been specifically and explicitly authorized by the proper authority to access, update, or delete the contents of an information asset
Authorization occurs after authentication
![Page 33: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/33.jpg)
Privacy
Information collected, used, and stored by an organization is to be used only for the purposes stated to the data owner at the time it was collected
Privacy as a characteristic of information does not signify freedom from observation
Means that information will be used only in ways known to the person providing it
![Page 34: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/34.jpg)
Accountability
Exists when a control provides assurance that every activity undertaken can be attributed to a named person or automated process
![Page 35: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/35.jpg)
Balancing Information Security and Access
Impossible to obtain perfect security—it is a process, not an absolute
Security should be considered balance between protection and availability
![Page 36: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/36.jpg)
Information Security: Is it an Art or a Science? Implementation of information security often
described as combination of art and science “Security artesan” idea
![Page 37: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/37.jpg)
Security as Art
No hard and fast rules nor many universally accepted complete solutions
No manual for implementing security through entire system
![Page 38: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/38.jpg)
Security as Science
Dealing with technology designed to operate at high levels of performance
Specific conditions cause virtually all actions that occur in computer systems
Nearly every fault, security hole, and systems malfunction are a result of interaction of specific hardware and software
If developers had sufficient time, they could resolve and eliminate faults
![Page 39: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/39.jpg)

Planning
• Planning as part of InfoSec management– An extension of the basic planning model
discussed earlier in this chapter
• Included in the InfoSec planning model – Activities necessary to support the design,
creation, and implementation of information security strategies
![Page 41: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/41.jpg)
Planning (cont’d.)
• Types of InfoSec plans– Incident response planning– Business continuity planning– Disaster recovery planning– Policy planning– Personnel planning– Technology rollout planning– Risk management planning– Security program planning
includes education, training and awareness
![Page 42: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/42.jpg)
Policy
• The set of organizational guidelines that dictates certain behavior within the organization
• Three general categories of policy: – Enterprise information security policy (EISP)– Issue-specific security policy (ISSP) – System-specific policies (SysSPs)
UNCW Policies
![Page 43: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/43.jpg)
Programs
• InfoSec operations that are specifically managed as separate entities– Example: a security education training and
awareness (SETA) program
• Other types of programs – Physical security program
complete with fire, physical access, gates, guards, etc.
![Page 44: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/44.jpg)
Protection
• Executed through risk management activities
– Includes:– Risk assessment and control– Protection mechanisms– Technologies– Tools
• Each of these mechanisms represents some aspect of the management of specific controls in the overall information security plan
![Page 45: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/45.jpg)
People
Managers must recognize the crucial role that people play in the information security program
This area of InfoSec includes security personnel and the security of personnel, as well as aspects of a SETA program
The most critical link in the information security program
![Page 46: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/46.jpg)
Project Management
Identifying and controlling the resources applied to the project
Measuring progress
Adjusting the process as progress is made
![Page 47: INFORMATION SECURITY MANAGEMENT I NTRODUCTION TO THE M GT OF I NFORMATION S ECURITY.](https://reader030.fdocuments.net/reader030/viewer/2022033105/5697bfd11a28abf838cab200/html5/thumbnails/47.jpg)
