Implement Firewalls and Access Control Lists (ACLs):
Firewalls serve to create a barrier between untrusted and trusted networks, restricting incoming and outgoing traffic based on predefined security policies. ACLs go a step further by establishing what users or devices can access specific resources or services. Together, they restrict the attack surface and deny unauthorized access.
Regular Patch Management and System Updates
Implementing security patches and updates in a timely manner prevents known vulnerabilities within operating systems, applications, and firmware from being exploited by attackers. Automation ensures constant security throughout the network.
