Laitteistopalomuuri, also known as "device firewall," is a security system designed to protect computer networks and devices from unauthorized access and cyber threats. It operates by monitoring and controlling incoming and outgoing network traffic based on predetermined security rules. These rules can be configured to allow or block specific types of traffic, such as certain protocols, ports, or IP addresses. The primary function of a device firewall is to create a barrier between a trusted internal network and untrusted external networks, such as the internet. By doing so, it helps prevent malicious activities like hacking attempts, malware infections, and data breaches. Device firewalls can be implemented in various forms, including hardware-based appliances, software solutions, and integrated features within operating systems and network devices. They are essential components of a comprehensive cybersecurity strategy, working in conjunction with other security measures like antivirus software, intrusion detection systems, and encryption to safeguard digital assets and maintain the integrity of network operations.
