Firewall is a network security device that allows or blocks network traffic flows that occur between a non-secure zone (eg the Internet) and a trusted zone (for example, a private or corporate network). A firewall should prevent any unwanted traffic, block “downtime” in the local network and it should protect the computers in it. One of the popular are Sonicwall firewalls which work is impeccable.
As a “traffic police” in the network, Firewall monitors all traffic and allows or disables the flow of traffic, so it is the best location for implementing security policies. That’s why we say that the Firewall is the most important security component in network infrastructure.
Do you have a company?
If we have learned so far about the owners of small and medium-sized companies, it is the fact that we all work hard to build the success of our companies. We understand the months of stress, the countless sleepless nights and all the other sacrifices that must be submitted to achieve the goals.
And we know that after all these efforts, tears and sweat, we really do not want to do anything that can jeopardize this success. But there is a lot of risk for any company that uses IT equipment or the Internet that can jeopardize business, and we want you to be safe and secure (at least as far as possible). That is why it is important to keep your company safe.
Types of firewalls
Firewall systems can perform different functions and offer different solutions, but the primary function of the firewall is to control access to specific resources. The firewall system consists of several different components. One of these components is filtering the network flow that most people call a firewall.
The firewall for filtering traffic consists of several different types, such as:
- Packet filtering firewall,
- Stateful firewall,
- Application gateway firewall,
- Address-translation firewall,
- Host-based firewall
- Hybrid firewall
Depending on the firewall filtering mode, they have different levels of protection. Of course, the way the firewall works much depends on the performance of the firewall itself.
High-tech crime / e-crime / cybercrime
High-tech crime, also known as e-crime or cybercrime, includes a set of offenses that involve the use of the Internet, a computer, or some other electronic device. Some forms of e-crime are directly related to computers, such as the spread of dangerous electronic viruses or the launch of Denial of Service Attack which disables the computer system so that it refuses to perform any service of an authorized user.
How to protect yourself from e-crime?
Make sure your internet transactions, as well as your customer information, are safe. Design a fair use policy in your workplace and inform your employees about it by entering it into individual contracts. Monitor the use of the Internet to make sure that this policy is respected. Fair Use Policy is a set of rules applied by the owner, author or network administrator, website or service that limits it and prescribes how to use the network, website, or system, and provide guidelines on how to use them.
