What you will gain after the course

  • Network Inspection for Critical Information and Communications Infrastructure

  • Risk Assessment and Action Plan Establishment

🚀 PM Project Management Capability Enhancement Training – Mastering Network Vulnerability Assessment Practice for Major Information and Communication Infrastructure (No Audio)

💡 “Can you judge a network check just by looking at the commands?”
The most core area in public institutions and major information and communication infrastructure
is network security inspection.
In this lecture, we will perfectly organize the practical network vulnerability inspection based on major information and communication infrastructure standards
at a professional level.


📌 This course is recommended for the following people!

👶 New Security Personnel – Those who are unfamiliar with network inspection commands
📊 Junior/Senior Practitioners – Those who have performed inspections but find the standards ambiguous
🧑‍💻 Infrastructure PL / PM – Those who need to understand both technical and management aspects
🛡️ Security Consultants – Those who want to strengthen their capabilities for public sector and ISMS-P compliance


🔥 Core Lecture Curriculum

🧩 1. Perfect Understanding of the Critical Information and Communication Infrastructure Network Inspection Structure

  • Inspection framework based on the protection measures for Critical Information and Communication Infrastructure

  • Summary of network inspection flow and overall structure

  • Explanation of core points you must know in practice


🔍 2. Key Account and Access Control Inspection

🔐 Account Security Management

  • Privilege Authorization Setting Check

  • Check whether secret encryption is applied

  • vty ACL access control configuration

🧑‍💻 Remote Access Security

  • Secure access policy allowing only SSH

  • Disable AUX port and configure no exec

  • Management of session timeout (based on 5 minutes)


📡 3. Network Service and Security Configuration Check

🌐 Network Protection Settings

  • SNMP Service Security Audit

  • ACL (Access Control List) policy check

  • Check Anti-DDoS settings

🚫 Block Dangerous Functions

  • Block proxy-arp

  • Block redirects

  • mask-reply blocking

📴 Basic Service Management

  • Checking the default deactivation of unnecessary services

  • The key point is "understanding the default state"

  • Focusing on the parts most frequently missed in actual field practice.


⚙️ 4. Core Technologies for Logging and Time Synchronization

📊 Log Management

  • logging host (Log Server IP) configuration

  • logging buffered / logging trap debugging

  • Essential use of the show logging command

⏱️ Time Management

  • NTP server configuration

  • timestamps configuration

👉 “Logs and time are the core of incident response”


📋 5. Practical-Focused Inspection Strategy

📌 Characteristics of Network Inspection

  • Most are inspections based on command results

  • Determining whether the service is active or inactive is key

📌 Analysis of Inspection Difficulty

  • Basic checks are easy, but

  • Many cases where the "Pass/Vulnerable criteria" are ambiguous

📌 Practical Know-how

  • Providing actual back data used in real projects

  • Summary of criteria for making judgments in ambiguous situations


📊 6. Expanding to the Project Management (PM) Perspective

📅 Inspection schedule and manpower management strategy
📄 How to write ISMS-P and Major Information and Communications Infrastructure reports
📈 Risk assessment and establishment of improvement measures
🧠 Practical management know-how applicable immediately in the field


🎯 What you will gain from this course

✅ Complete understanding of major information and communication infrastructure network inspection standards
✅ Acquisition of inspection capabilities based on network equipment commands such as Cisco
✅ Improvement in log analysis and security setting judgment capabilities
✅ Strengthening of ISMS-P and public security response capabilities
✅ Acquisition of checklists that can be used immediately in practice


👨‍🏫 Lecture Differentiation Points
📚 "Field Practice-Oriented Education" rather than theory
🛠️ Case-oriented explanations based on actual projects


💬 Core One-Line Summary
👉 “A lecture that transforms network inspection from a 'list of commands' into 'decisive practical competence'”


⚠️ Key Point!

📢 Network inspection is not just a simple check, but an "interpretation skill"
📢 If you don't properly understand the command results, they are meaningless
📢 This lecture will establish those "interpretation standards" for you


⏳ Start now!
If you want to take your network security skills to the next level,
this course is the fastest way. 🚀
