Case Study: Securing a Network with 50 Computers

This case study presents a comprehensive solution for securing and backing up a corporate network with 50 computers. The goal is to protect data against cyber threats such as ransomware, data loss, and operational disruption.

1. Introduction

The study covers analysis of the current situation, solution design, implementation, testing, and long-term maintenance.

2. Current Situation Analysis

The following weaknesses were identified:

• Missing central backup system
• No automated backups or regular testing
• No network segmentation, increasing the risk of malware spreading
• Insufficiently restricted user access rights

3. Solution Design

The proposed solution includes:

• NAS device: Synology DS1524+ or QNAP TS-453D
• Professional backup software (Veeam Backup or Acronis Cyber Protect)
• Network segmentation using VLANs
• Automated backups to NAS, cloud, and external HDD
• Data encryption and backup status monitoring

4. Implementation

Implementation included NAS installation, backup software configuration, network segmentation, and cloud backup setup. Backup policies were established and testing was performed.

5. Testing and Monitoring

Testing included data recovery from local and cloud backups, access verification, and failure simulations. Regular monitoring ensured ongoing backup verification.

6. Long-term Maintenance

Includes regular updates, recovery testing, security audits, and employee training.

7. Costs and Timeline

Estimated solution costs:

• NAS Synology DS1522+: CZK 18,500 – 21,800
• Veeam backup software: CZK 10,000 – 15,000/year
• Acronis Cyber Protect: CZK 4,000 – 6,000/year per device
• Hard drives: CZK 12,000 – 15,000
• Cloud storage: CZK 100 – 200/month per TB
• Implementation time: 8 – 11 business days

8. Benefits of the Proposed Solution

• Enhanced data protection against ransomware and other threats
• Easy management and fast data recovery in case of outage
• Customizable solution for various business needs
• Combination of local and cloud backups for greater security
• Continuous monitoring and simple management

FAQ

How often should backups be performed?
We recommend daily incremental backups and weekly full backups.

What are the benefits of cloud backup?
Cloud backup protects data from physical threats such as fire or theft.

Is employee training necessary?
Yes, employees should be trained on cybersecurity and data recovery procedures.
