To enhance internet and IT security in a business, a combination of tools and strategic practices is essential. Here’s a list that encompasses both:

**Security Tools:**

1. **Firewalls:** Use hardware and software firewalls to protect your network from unauthorized access and monitor traffic.

2. **Antivirus and Anti-Malware Software:** Employ comprehensive antivirus solutions to protect against malware, ransomware, and other threats.

3. **Intrusion Detection and Prevention Systems (IDPS):** Implement IDPS to detect and respond to suspicious activities on the network.

4. **Virtual Private Network (VPN):** Utilize VPNs for secure remote access to your business network, ensuring data is encrypted during transmission.

5. **Data Encryption Tools:** Encrypt sensitive data both at rest and in transit to protect it from unauthorized access.

6. **Multi-Factor Authentication (MFA):** Implement MFA to add an extra layer of security beyond just passwords.

7. **Secure Wi-Fi Networks:** Use WPA3 or the latest secure Wi-Fi standards and regularly change Wi-Fi passwords.

8. **Patch Management Software:** Keep all software up-to-date with the latest patches to fix vulnerabilities.

9. **Email Security Solutions:** Deploy email security tools to filter out spam, phishing emails, and other malicious content.

10. **Web Application Firewalls (WAF):** Protect your web applications from various attacks such as SQL injection and cross-site scripting (XSS).


**Security Practices and Tips:**

1. **Regular Security Audits:** Conduct regular security assessments to identify vulnerabilities and improve defenses.

2. **Employee Training:** Educate employees about cybersecurity risks such as phishing, social engineering, and safe internet practices.

3. **Data Backup:** Regularly backup important data and store it securely, ideally offsite or in the cloud, to prevent data loss.

4. **Least Privilege Principle:** Implement access controls and ensure employees only have access to the information necessary for their roles.

5. **Strong Password Policies:** Enforce strong password policies and encourage the use of password managers.

6. **Incident Response Plan:** Have a well-defined incident response plan for handling security breaches or data leaks.

7. **Secure Configuration:** Ensure that all systems and software are configured securely by default.

8. **Network Segmentation:** Segment your network to limit the spread of malware and ease network management.

9. **Regularly Update Security Policies:** Keep your cybersecurity policies updated in response to new threats and changing business processes.

10. **Vendor Risk Management:** Evaluate the security protocols of third-party vendors and partners to ensure they meet your security standards.

Implementing these tools and practices creates a robust security framework that protects a business from a wide array of cyber threats and vulnerabilities.
