Study Notes

Information Security Areas

Three primary areas: People, Data, Attacks
People focuses on authentication and authorization to prevent scams
Data involves prevention and resistance to attacks.
Attacks involve detection and response to threats.

Authentication

Authentication verifies user identity.
Authorisation grants access levels and permissions to a user.

General Authentication

Public Key Encryption uses two keys: a public key accessible to everyone and a private key for individual use.
Private key typically decrypts; public key typically encrypts.
Authorization levels:
- None: No access to target information
- Read: View only target information
- Read/Write: View and modify target information
- Delete: Remove target information

Single-Factor Authentication

Uses a single factor like a username and password
Password is a string of alphanumeric characters.

Two-Factor Authentication

Combines single-factor authentication with a security token (something the user has)

Access Control Model (Four)

Mandatory Access Control: Most restrictive, giving control to a system owner/administrator
Discretionary Access Control: Least restrictive, giving complete control to the owner/administrator
Role-Based Access Control: Popular method, assigning permissions based on user roles.

Data Prevention and Resistance

Content Filtering: Software filters content to prevent accidental or malicious transmission.
Encryption: Scrambles data to prevent unauthorized decryption.
Firewall: Network security that guards a private network by analyzing incoming and outgoing information.

Attack: Detection and Response

Intrusion Detection System (IDS): Monitors network traffic to identify intruders
Intrusion Prevention System (IPS): Monitors network activities, detects intrusions, and blocks malicious activities.

Business Process Model

A graphical depiction of a process, showing tasks and sequence.
Business Process Model Notation (BPMN): A graphical notation for depicting steps of a business process.
Activity, Task, Work performed
Event: Anything happening during the business process (ex. Customer requests)
Workflow: Includes tasks, activities and responsibilities needed to execute each step of a business process (ex. Tasks involved in processing a customer order.)

As-Is and To-Be Process Models

As-Is: Represents the current state of an operation.
To-Be: Shows the result of applying changes to the existing processes.
