Internet security is a key aspect of any company’s operation. Cyber attacks, data breaches, phishing, and ransomware can cause massive financial and reputational losses. In the era of digitalization and remote work, organizations must implement effective strategies to protect their resources. This article presents a comprehensive approach to internet security for companies, including protection of computer networks, cloud data, and tools used in daily work.
1. Computer Network Protection
a) Firewalls and IDS/IPS systems
Every company should deploy network firewalls (firewalle) and intrusion detection and prevention systems (IDS/IPS), which monitor network traffic and block suspicious activity.
b) Network segmentation
Dividing IT infrastructure into different segments (e.g., office, production, guest networks) limits the impact of potential attacks and improves resource management.
c) Wi-Fi security
Wireless networks should be protected with strong encryption (WPA3), and access to them should be controlled through unique passwords for each user.
d) Monitoring and security audits
Regular network scanning and security audits help detect potential vulnerabilities and eliminate threats before they are exploited by cybercriminals.
2. Cloud Solution Security
a) Choosing a trusted provider
Before deploying cloud services, it is essential to thoroughly verify the service provider’s security policy, compliance with standards (e.g., ISO 27001), and data encryption availability.
b) Access management
Access to cloud resources should be regulated according to the principle of least privilege (PoLP). It is crucial to use strong passwords and multi-factor authentication (MFA).
c) Data encryption
Data stored and transmitted in the cloud should be encrypted both on the client-side and provider-side. It is recommended to use internally managed encryption keys.
d) Backup and data recovery
Regular backups and testing of data recovery procedures minimize the risk of information loss due to failures or ransomware attacks.
3. Identity Management and Access Control
a) Password policy
All company accounts should have strong, unique passwords, stored and managed by password managers. Regular password changes and using phrases instead of simple combinations of characters significantly increase security.
b) Multi-factor authentication (MFA)
Implementing MFA makes it difficult for unauthorized individuals to access systems. It is recommended to use authentication apps like Google Authenticator or Microsoft Authenticator.
c) Role-Based Access Control (RBAC)
Each user should have access only to resources necessary for their tasks. Implementing RBAC allows for precise management of permissions.
d) Incident detection and response
SIEM (Security Information and Event Management) systems enable real-time monitoring and analysis of logs, as well as detecting suspicious activities. Response to incidents should be part of the company’s security policy.
4. Employee Cybersecurity Education
a) Training and phishing simulation
Regular training increases employee awareness of threats. Phishing simulations allow testing educational programs’ effectiveness.
b) BYOD (Bring Your Own Device) policy
If a company allows employees to use personal devices for work, it should implement safety guidelines, such as system updates and antivirus software installation requirements.
c) Social engineering awareness
Employees should be aware of social engineering threats – manipulations aimed at obtaining sensitive information. Phishing, vishing, or smishing attacks are among the most common types of deception.
5. Protection against Cyber Threats
a) Regular software updates
Outdated operating systems and applications may contain security vulnerabilities exploited by cybercriminals. Automatic updates should be standard.
b) Malware protection
Antivirus software, EDR (Endpoint Detection and Response), and WAF (Web Application Firewall) help detect and eliminate malware-related threats.
c) Incident response plan
Every company should have a procedure for responding to cyber attacks, including quick isolation of the threat, informing relevant teams, and data recovery.
Summary
Internet security requires a comprehensive approach that includes network protection, cloud data management, access policies, and employee education. Implementing modern solutions like MFA, RBAC, SIEM, or network segmentation reduces the risk of cyber attacks and data loss. In today’s world, where digital threats are becoming increasingly sophisticated, every company should prioritize security. A website or an online store is also a very vulnerable place for such attacks.
