Introduction: Problem Definition or Background
The increasing sophistication of cyber attacks is threatening the information assets of businesses and individuals. In 2026, the advancement of Agentic AI technology is expected to bring even more complex and unpredictable security threats. Therefore, establishing proactive security strategies for system protection and customer information security is essential. In an unstable global environment, consumers are seeking stability, requiring companies to build more robust and reliable security systems. This goes beyond mere technological investment; it plays a crucial role in building and maintaining trust with customers.
Core Concepts and Principles
A security system is a collection of technical and administrative measures designed to protect information assets. This includes access control, encryption, intrusion detection, and vulnerability management. The core principles are the 'Principle of Least Privilege,' 'Defense in Depth,' and 'Continuous Monitoring.' The Principle of Least Privilege reduces the threat from insiders by granting users only the minimum necessary permissions. Defense in Depth involves building multiple layers of security to ensure that even if one line of defense is breached, others remain in operation. Continuous Monitoring involves constantly monitoring the system's status to detect and respond to anomalies early.
Detailed Item 1: Access Control
Access control consists of user authentication, authorization, and access auditing. Strong authentication mechanisms (e.g., multi-factor authentication) are used to verify user identities, and role-based access control (RBAC) grants users only the necessary permissions. Additionally, all access attempts are logged and audited to detect abnormal activity.
Detailed Item 2: Encryption
Encryption is an essential technology for securely transmitting and storing data. Data in transit is encrypted using TLS/SSL protocols, and data at rest is encrypted using algorithms such as AES and RSA. Encryption key management is critical to security, and a secure key management system must be established.
Latest Trends and Changes
Agentic AI is expected to have a significant impact on the security field in 2026. Agentic AI can automatically respond to security threats by learning and making decisions independently. Furthermore, the advancement of quantum computing technology can neutralize existing encryption algorithms, making research and adoption of post-quantum cryptography (PQC) technology crucial. According to Euromonitor International, global consumers in 2026 will seek comfort and simplicity and tend to seek stability in an unstable global environment. This means that security systems must be user-friendly and easy to use.
- 2026 Technology Trends: Major institutions such as Gartner and IDC have identified Agentic AI, Infrastructure, Security, Physical AI, and Quantum Computing as key trends. The era of Agentic AI is expected to arrive, moving beyond generative AI.
- Global Consumer Trends: According to Euromonitor International, global consumers in 2026 will seek comfort and simplicity and tend to seek stability in an unstable global environment.
Practical Application Plans
In practice, the following security application plans can be considered. First, adopt a Zero Trust Architecture (ZTA) to verify all users and devices continuously, without trusting anyone. Second, build a Security Information and Event Management (SIEM) system to manage and analyze security events and logs in an integrated manner. Third, improve the security awareness of employees through regular security education and training. By referring to various tax-related cases in the National Tax Laws Information System, tax-related risks can be prevented.
Expert Suggestions
💡 Technical Insight
Precautions When Introducing Technology: Before introducing new security technologies, thorough review and testing are necessary. In particular, advanced technologies such as Agentic AI can have unexpected side effects, so it should be introduced carefully with the help of experts.
Outlook for the Next 3-5 Years: Cyber attacks will become more intelligent and complex over the next 3-5 years. Companies must build AI-based security systems and introduce post-quantum cryptography (PQC) technology to prepare for future threats. In addition, the shortage of security personnel will become more severe, increasing the demand for automated security solutions and security professional services.
Conclusion
The 2026 security trends will revolve around system protection and customer information security. The development of new technologies such as Agentic AI and quantum computing is changing the landscape of security threats, and companies must prepare for them. By improving security levels through practical application plans such as Zero Trust Architecture, building SIEM systems, and providing security education, and by proactively responding to future threats based on expert advice. Ultimately, building a robust security system will strengthen trust with customers and enable the company's continued growth.
