With the rapid spread of technology and increasing the popularity of the internet every day. There is no home or workplace where the internet does not enter. The Internet has become the sine qua non of our lives. Nowadays, the concept of network security and firewall have become even more important with the fact that things are running on the internet.
With the attacks, the service can be prevented, data losses can occur and material losses can occur unimaginably. A recent attack on DynDNS has caused access to many sites. And it caused serious material loss.
Network security does not consist of a single factor. For example, using a firewall does not mean that you are securing that network. To ensure complete security, you must bring together a variety of solutions and select the appropriate hardware and software for your system. Thus, even if a solution fails, other solutions will continue to provide protection.
The reason for this is the continuous development of technology and the attacks on the systems (networks) increase with this progress. For example, you store your valuables and money in your home safe. You also take a number of measures, such as a security guard, an alarm system in your home.
You can also consider network security as in this example. As a result, we have no choice but to pay attention to our bank accounts, credit card numbers and use your private information on the Internet. Imagine that your credit card number has fallen into the hands of hackers or that your credentials have been compromised. No one would want your information to be spent, made transactions, and made it look like you’re doing it, right?
Firewall, IPS, VPN, SSL
Firewalls are an essential part of network security. The firewall controls the flow of traffic between networks within the rules defined on it. The most common use is to protect your organization’s internal network from internet-related hazards. It examines incoming traffic, compares it with the rules defined on it, blocks traffic according to the result, permits traffic or forwards it to other network security technologies for further action.
The most basic capabilities of these products are access control, authentication, NAT. In addition to these basic functions, today’s firewalls have many capabilities. (VPN, SSL, IPS, URL Filtering, Web Security, Antivirus, Anti-Spam, Anti-Malware, Clustering, VOIP, etc.) Because of their capabilities far beyond a firewall. These advanced solutions can use as “Security Gateway” or next-generation firewall. also called.
