Information cybersecurity (InfoSec) is the protection of information and systems from unauthorized access, use, or modification. Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. While the terms are often used interchangeably, information security is broader and includes physical security, endpoint security, and encryption.
Ways to Protect Information and Systems
Nonrepudiation: The sender receives proof of delivery and the recipient receives proof of the sender’s identity.
Identity and access management (IAM): Tools and strategies that control how users access resources and what they can do with them.
Adaptive authentication: Detects when users are engaging in risky behavior and raises additional authentication challenges.
Zero trust architecture: Verifies all connection requests between users and devices, applications, and data.
Cloud security: Ensures data remains private and secure as it passes between different internet-based applications.
IoT (Internet of Things) security: Secures smart devices and networks connected to the IoT.
Information Cybersecurity (InfoSec) Skills
Competence in information security encompasses a blend of technical skills, knowledge, experience, and the application of these attributes to protect information assets effectively. It involves understanding complex systems, identifying potential threats, and implementing strategic defenses.
For example, an endpoint detection and response (EDR) tool can automatically respond to a threat using predetermined rules. Endpoint security solutions can employ additional strategies to protect endpoints, such as data encryption in transit and at rest, web content filtering, and application control.
Information cybersecurity (InfoSec) is only one dimension of cybersecurity.
