Võrguseinad

Võrguseinad, meaning "network walls" in Estonian, refers to firewalls used to protect computer networks. These are essential security devices that monitor and control incoming and outgoing network traffic based on predetermined security rules. A firewall acts as a barrier between a trusted internal network and untrusted external networks, such as the internet.

The primary function of a võrgusein is to prevent unauthorized access to a private network. It achieves this by analyzing data packets and deciding whether to allow or block them based on a set of rules. These rules can be configured to block specific IP addresses, ports, or even certain types of applications. By doing so, võrguseinad help protect against various cyber threats, including malware, viruses, and hacking attempts.

There are several types of võrguseinad, including hardware firewalls, software firewalls, and cloud-based firewalls. Hardware firewalls are dedicated physical devices, while software firewalls are applications installed on individual computers. Cloud-based firewalls are hosted by a third-party provider and protect networks from the cloud. The choice of firewall depends on the specific needs and size of the network being protected. Implementing and maintaining effective võrguseinad are crucial for maintaining the security and integrity of digital information.
