Introduction to Infosec
Information Security (Infosec) refers to the processes and methodologies designed to protect digital and analog information from unauthorized access, use, disclosure, disruption, modification, inspection, recording, or destruction. It encompasses a broad spectrum of practices, tools, and concepts aimed at securing data and information systems. Examples of Infosec in action include encryption, which scrambles data so that it can only be read by someone with the key; firewalls, which serve as barriers between secure internal networks and potentially insecure external networks; and intrusion detection systems (IDS), which monitor networks for malicious activities or policy violations. A real-world scenario illustrating these aspects could involve a financial institution implementing layered security measures to protect sensitive customer data. This could include using encryption for data at rest and in transit, employing firewalls to guard the perimeter of its network, and deploying IDS to detect and respond to potential threats in real time.

Main Functions of Infosec
Protecting data confidentiality
ExampleEncryption of sensitive files
ScenarioA healthcare provider encrypts patient records to ensure that even if a data breach occurs, the information remains unreadable to unauthorized individuals.
Ensuring data integrity
ExampleDigital signatures
ScenarioAn e-commerce platform uses digital signatures to verify that messages or transactions have not been altered during transmission, thus ensuring the integrity of communication between buyers and sellers.
Maintaining availability
ExampleRedundant systems and backups
ScenarioAn online service provider implements redundant infrastructure and regular backups to ensure service availability even in the event of hardware failures or cyberattacks.
Threat detection and response
ExampleIntrusion Detection Systems (IDS) and Security Information and Event Management (SIEM)
ScenarioA corporation uses IDS to monitor its network for suspicious activities and SIEM to analyze and manage security alerts, enabling rapid response to potential security incidents.
User authentication and access control
ExampleMulti-factor authentication (MFA)
ScenarioA financial institution requires MFA for all online banking transactions, adding an extra layer of security by requiring users to provide two or more verification factors to gain access to their accounts.
