Study Notes
Introduction to Information Security Management
- Course details: 1502373 - Information Security Management, Spring 2024-25, taught by Dr. Saddaf Rubab, in MS-220
- Quote from Book of the Five Rings: "Do not figure on opponents not attacking; worry about your own lack of preparation."
- Information security issues can exist even with comprehensive protections in place
- Examples of security problems: poor passwords, security breaches in security practices, credential spills, credential abuse
Information Security Management
- Real-life data breaches occur due to insider threats
- Data breaches caused by malicious or inadvertent insider actions result in financial and reputational damage
- The importance of understanding information assets, security threats and how to prepare for incidents is highlighted
Early Forms of Information Security
- German Enigma code machines broken earlier by the Poles (1930s) and later by the British/Americans during World War II
- Allied forces benefited from decryption of German communications
- Complex versions of the Enigma machine caused considerable issues for the allied forces before being cracked
The 1990s
- Increased networking and internet use created the need to interconnect networks
- Security wasn't treated as a priority in early internet deployments
2000 to Present
- Internet connects various (and many insecure) computer networks
- A computer's security depends on the security of the interconnected systems
- Increased cyberattacks necessitate improved security efforts
Information
- Data is an asset that, like other critical business components, requires safety
- Information assets need security protection
Information Can Be
- Information is displayed, transmitted, shown on video, displayed/published online, stolen, printed/written on paper, stored electronically, and created
- Information, regardless of form, must be appropriately protected
What is Security
- Organizations should use multiple layers of security measures (physical, personal, operations, communication, network, and information security)
What is Information Security?
- Information security aims to safeguard organizational data assets
Components of an Information System
- Information systems consist of software, hardware, data, people, procedures, and networks
- Understanding these components is crucial to fully grasping the importance of information security
Key Information Security Concepts
- Protection profile/security posture: Information security evaluation
- Risk: The potential loss associated with a threat
- Subjects and objects: Subjects are users and devices; objects are data
- Threat Agent: A person or organization that could pose a threat
- Vulnerability: A weakness that can be exploited
- Access, Asset, Attack, Control/Safeguard, Exploit, Exposure, and Loss are key facets of security
Components of Information Security
- Confidentiality, Integrity, and Availability (CIA) are the core elements of information security.
- Managing computer security, data security, and network security is essential
Confidentiality
- Access to information restricted to authorized users
- Measures like classification, secure storage, security policies, and user education are important
Integrity
- Information accuracy and completeness are maintained
- Data quality is preserved and safeguards against corruption, damage, destruction, or disruption of information
Availability
- Authorized users can access data when needed without interference
- Data should be available in the required format to authorized users
Key Concepts of Information Security (Authentication and Authorization)
- Authentication: Verifying a user's identity
- Three types of authentication: Something you know, something you have, something you are
- Authorization: Granting access based on the authenticated user's role or permission
- Access control regulates interactions with assets and dictates permitted actions
Key Concepts of Information Security (Accountability)
- Tracking actions to accountable parties.
The Operational Method of Computer Security and Technologies
- Protection: Prevention, detection, and response
- Prevention, Detection, and Response (PDR) is a comprehensive approach
- Access controls, firewalls, encryption, audit logs, intrusion detection systems, honeypots, incident response teams, and computer forensics are used
Securing the Components
- Computers can be attacked or used to launch attacks
- Attack subjects and objects, along with attack methods.
CNSS Security Model
- Policy, Education, Technology.
- CIA's principles are crucial aspects of computer security.
Balancing Security and Access
- Balancing security with access to systems requires understanding how to protect data and user security
On-Going Process
- Perfect security is unachievable; ongoing improvements and risk management are critical
- Security needs continuous monitoring and improvement.
