Information Cybersecurity (InfoSec)
Understanding Information Cybersecurity
What Is Information Cybersecurity (InfoSec)?
Information cybersecurity, often referred to as InfoSec, is the protection of information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction.
Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. While the terms are often used interchangeably, information cybersecurity is broader. It includes not only technical protections, but also physical security, endpoint protection, and data encryption.
From a business perspective, InfoSec plays a critical role in identifying and reducing risk. It is a core component evaluated during a cyber risk assessment, helping organizations understand how information is stored, accessed, and protected across the environment.
Information Security (InfoSec) ensures three core objectives: Confidentiality, Integrity, and Availability (the CIA Triad). The foundation of InfoSec is defined by these three pillars:
Confidentiality: Ensures only authorized users and systems can access and/or modify data.
Integrity: Ensures that stored data is not altered without proper permissions.
Availability: Deals with ensuring timely and reliable access to and use of data and systems.
InfoSec and Third Party Risk Management
In the context of Third-Party Risk Management (TPRM), InfoSec is a primary focus during the Pre-Contract Due Diligence phase, where an organization evaluates the security posture of potential vendors through robust risk assessments. An InfoSec Questionainaire is often part of a good risk assessment, and is used to identify residual risk by evaluating a third party's controls. This shouls cover several critical domains:
Data Protection: Evaluates data governance, data loss prevention, recovery & integrity controls.
Encryption: Focuses on encryption protocols, key mgmt, and password storage. (Assessors seek unsafe standards (i.e.SHA-1 algorithm), and contrast them with safe standards (SHA-2).
Network Security: Covers patch management, network segmentation, pen testing & more. Assessors flag unsafe issue like Port 25 (SMTP) unencrypted or Port 23 (TELNET) unsafe.
Access Controls & Authentication: Includes reviews of Multi-Factor Authentication (MFA), Single Sign-On (SSO) & privileged access management (PAM). For example, having no limits on login attempts is identified as a brute force attack vulnerability.
Application & Server Security: Involves testing applications, managing server configurations, and reviewing Software Development Lifecycle (SDLC) practices for software vendors.
Incident Response: Evaluates vendor plans & testing for security events, incidents, or breaches.
Ways to Protect Information and Systems
Information cybersecurity relies on a combination of technical safeguards, policies, and access controls. Common approaches include:
Nonrepudiation - Ensures 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 systems, data, and applications, and what actions they are allowed to perform.
Multi-Factor Authentication (MFA) - Requires users to supply multiple credentials to verify identity before access is granted.
Adaptive Authentication - Detects risky or unusual behavior and applies additional authentication challenges when needed.
Zero Trust Security - Verifies all connection requests between users, devices, applications, and data, rather than assuming trust based on location.
Cloud Security - Protects data as it moves between internet-based applications and cloud platforms.
IoT Security - Secures smart devices and networks connected to the Internet of Things.
These controls are commonly reviewed during a cyber risk assessment to identify gaps that could expose sensitive information.
Information Cybersecurity (InfoSec) Skills
Competence in information cybersecurity requires a blend of technical skills, knowledge, and experience. It involves understanding how information flows through systems, identifying potential threats, and applying appropriate cybersecurity controls to reduce risk.
For example, endpoint protection tools such as EDR solutions can automatically respond to threats using predefined rules. Endpoint security solutions may also include:
Data encryption at rest and in transit
Web content filtering
Application control
Together, these capabilities help protect information assets across user devices and systems.
How InfoSec Fits Into Cybersecurity
Information cybersecurity is only one dimension of cybersecurity. While network security focuses on protecting connectivity and infrastructure, InfoSec focuses on safeguarding the information itself.
For small and mid-sized businesses, understanding this distinction is important. A strong InfoSec program supports better decision-making, improves resilience, and strengthens outcomes identified through a cyber risk assessment.
How tekrisq Supports SMBs with Information Cybersecurity
tekrisq helps small and mid-sized businesses understand and manage information cybersecurity as part of a practical, risk-based approach.
Rather than focusing on tools alone, tekrisq evaluates how information is accessed, protected, and shared across the business. This includes identifying weaknesses uncovered during a cyber risk assessment and helping organizations prioritize actions that meaningfully reduce risk.
By aligning InfoSec with business operations and real-world threats, tekrisq helps SMBs improve security without unnecessary complexity.
