Information Security Management Do not figure on opponents not attacking; worry about your own lack of preparation. BOOK OF THE FIVE RINGS

Information Security Management You can have all the protection mechanisms in place and still have security problems:

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: n Everything cannot be categorized as right or wrong n What works for one company may fail in another

Certified Information Systems Security Professional (CISSP) n Five years of experience in information security n There are 250 multiple-choice questions n Exam duration: six hours

SSCP - Systems Security Certified Practitioner n Only one year of experience required n Test is 90 minutes long, 50 -70 questions

Associate of (ISC)^2 Certification n No experience required n Shows that you passed the exam, and that you are serious about a career in Information Security n Subscribe to the (ISC)² Code of Ethics

Early forms of Information Security Figure 1 -1 The Enigma Source: Courtesy of National Security Agency

The 1990 s n Networks of computers became more common; so too did the need to interconnect networks n Internet became first manifestation of a global network of networks n In early Internet deployments, security was treated as a low priority

2000 to Present n The Internet brings millions of computer networks into communication with each other —many of them unsecured n Ability to secure a computer’s data influenced by the security of every computer to which it is connected n 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 q 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 (Info. Sec 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

What Is Information Security? What is Information security? How do we achieve Information Security? q Policy q Technology q Training and Awareness Programs Role of information security is to protect an organization’s information assets

Components of an Information System n Information system (IS) is entire set of components necessary to use information as a resource in the organization Software n Hardware n Data n People n Procedures n Networks n Principals of Information Security, Fourth Edition 22

CNSS Security Model (cont’d. ) q C. I. A. triangle – Confidentiality, integrity, and availability – Has expanded into a more comprehensive list of critical characteristics of information q 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. ) q 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 The value of information comes from the characteristics it possesses Exp and incl ed to ude Identification Authentication Authorization Privacy Accountability

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 n 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 n Impossible to obtain perfect security—it is a process, not an absolute n Security should be considered balance between protection and availability

Information Security: Is it an Art or a Science? n Implementation of information security often described as combination of art and science n “Security artesan” idea

Security as Art n No hard and fast rules nor many universally accepted complete solutions n No manual for implementing security through entire system

Security as Science n Dealing with technology designed to operate at high levels of performance n Specific conditions cause virtually all actions that occur in computer systems n Nearly every fault, security hole, and systems malfunction are a result of interaction of specific hardware and software n If developers had sufficient time, they could resolve and eliminate faults

Principles of Information Security Management Include the following characteristics that will be the focus of the current course (six P’s): 1. Planning 2. Policy 3. Programs 4. Protection 5. People 6. Project Management http: //csrc. nist. gov/publications/Pubs. TC. html

Planning • Planning as part of Info. Sec management – An extension of the basic planning model discussed earlier in this chapter • Included in the Info. Sec planning model – Activities necessary to support the design, creation, and implementation of information security strategies

Planning (cont’d. ) • Types of Info. Sec plans – Incident response planning – Business continuity planning – Disaster recovery planning – Policy planning – Personnel planning – Technology rollout planning – Risk management planning – Security program planning n 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 (Sys. SPs) UNCW Policies

Programs • Info. Sec operations that are specifically managed as separate entities – Example: a security education training and awareness (SETA) program • Other types of programs – Physical security program n 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 Info. Sec 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

Summary • What is security? • Principles of information security management – – – Planning Policy Programs Protection People Project management

Next Class (in 2 weeks) • Read Chapter 2 – Planning for Security • Signup for Entropy • Lecture Slides and additional readings will be posted in the calendar • Teams and Topic Selections • I will cover discussion of cases and current events next week but read them before class!
