• Remove or update legacy software that is no longer supported by the vendor.

By staying current with software updates, you can ensure that your systems are protected against known security vulnerabilities and reduce the likelihood of a successful attack.

3. Secure Network Perimeters

Securing network perimeters is essential for preventing unauthorized access to systems and data. Network perimeters act as the first line of defense against external threats, making it crucial to implement robust security measures. To secure network perimeters effectively, consider the following practices:

• Install and configure firewalls to monitor and control incoming and outgoing network traffic.
• Use virtual private networks (VPNs) to encrypt data traffic and establish secure connections.
• Implement intrusion detection and prevention systems to detect and respond to suspicious network activity.

By fortifying network perimeters with these security measures, you can reduce the risk of unauthorized access and enhance the overall security of your systems.

4. Conduct Regular Security Audits

Regular security audits are essential for evaluating the effectiveness of your system security measures and identifying potential vulnerabilities. By conducting comprehensive security audits, you can proactively assess the security posture of your systems and take remedial action where necessary. Consider the following practices when conducting security audits:
