Introduction to Information Security Management
Do not figure on opponents not attacking;worry about your own lack of preparation.

Technology is not enough…..(From: PWC Global State of Information Security 2015)
Even the best technological solutions are being constantly worked on to circumvent.
Essential governance and operational processes:•Incident management response process•Classifying business value of data•Risk assessments on internal systems•Security Audits•Governance, risk and compliance

Information Security Management
The goal of this course is to take a step back and examine how security functions as a whole within the organization.
Challenge:Everything cannot be categorized as right or wrong
What works for one company may fail in another

Early forms of Information Security
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
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
Information Security Decision Makers
1) Information security mgr and professionals (InfoSec Community)
2) Information technology mgr and professionals(Information Technology Community)
3) Non-technical business mgr and professionals (General Business Community)
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
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
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
Integrity
The quality or state of being whole, complete, and uncorrupted
Threats to information integrity:– Corruption– Damage– Destruction– Other disruption of its authentic state
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)
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
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
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
Accountability
Exists when a control provides assurance that every activity undertaken can be attributed to a named person or automated process
Balancing Information Security and Access
Should everyone have an access button?
Should information be kept in a vault?
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
Principles of Information Security Management
Include the following characteristics that will be the focus of the current course (six P’s):

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
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
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
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.
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
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
Project Management
Identifying and controlling the resources applied to the project
Measuring progress
Adjusting the process as progress is made
