How to Choose the Right Security System

Choosing the right security system requires a comprehensive assessment based on five dimensions: needs alignment, technical capabilities, compliance requirements, cost-effectiveness, and scalability. The following are specific steps and key points:

1. Clarifying Core Needs: From "What to Protect" to "What to Defend Against"
Protection Objects:
Data: Does it require encrypted storage and leakage prevention (e.g., customer information, R&D code)?
Endpoints: Do employee devices need to be managed (e.g., disabling USB drives, restricting software installation)?
Network: Does it require protection against external attacks (e.g., DDoS, APT) or internal threats (e.g., unauthorized access)?
Business Systems: Does it require ensuring critical business continuity (e.g., trading systems, production control)?
For example: Financial companies may prioritize protecting transaction data and terminal compliance, while manufacturing may focus more on industrial control system security.
Threat Scenarios:
External Attacks: Hacker intrusion, ransomware, phishing attacks.
Internal Risks: Employee misoperation, data theft, and privilege abuse.
Compliance Risks: Data privacy regulations (e.g., GDPR) and industry regulatory requirements (e.g., SSL 2.0). Example: The healthcare industry needs to prevent patient data leaks while also complying with the requirements of the Personal Information Protection Law.

II. Assessing Technical Capabilities: Do the functions cover core requirements?

Basic Protection Functions:

Antivirus/Anti-Ransomware: Does it support real-time scanning, behavior monitoring, and ransomware isolation?

Data Encryption: Does it support transparent encryption, permission control, and audit logs?

Access Control: Does it support multi-factor authentication (MFA) and granular permission management?

Example: Choose a security system that supports "export approval" to prevent employees from leaking sensitive data via email or cloud storage.

Advanced Threat Response:

AI Behavioral Analysis: Can machine learning identify abnormal operations (such as nighttime batch downloads)?

Zero Trust Architecture: Does it default to distrusting all devices/users and continuously verify identity and security status?

Threat Hunting: Does it support proactive searches for potential attack traces (such as hidden backdoors)?

Example: Choose a system with integrated EDR (Endpoint Detection and Response) capabilities to quickly isolate infected endpoints and trace the attack path. Compatibility and Integration:
Cross-Platform Support: Is it compatible with Windows, Linux, macOS, and mobile devices?
Integration with Existing Systems: Can it integrate with firewalls, SIEM (Security Information and Event Management), and IAM (Identity Access Management)?
Example: If an enterprise already has a Palo Alto firewall deployed, it can choose a security system that supports its API to enable threat intelligence sharing.
III. Verifying Compliance: Avoiding Legal and Regulatory Risks
Domestic Regulations:
Level 2, Level 3, and Level 4 security requirements must be met (e.g., log retention for at least six months).
Data Security Law: Requires classified and graded protection of important data.
Example: Government agencies should choose a security system certified under Level 4.
International Regulations:
GDPR: The EU's data protection regulation, which requires data minimization and cross-border transfer compliance.
HIPAA: The US healthcare privacy regulation, which requires patient data security.
Example: A cross-border e-commerce company should choose a security system that supports GDPR data encryption and auditing.
