Why is firewall security necessary for small businesses?

Firewall is a network security device that filters traffic from hackers and virus attacks so that they cannot sabotage or paralyze the network system. Because all incoming and outgoing access sources between the internal network and other networks must pass through the firewall, the firewall also has the effect of monitoring and analyzing traffic flows and deciding what to do with significant traffic flows.

Firewall systems are often very popular in medium to large sized businesses. Small businesses often do not prioritize investing in this issue. However, with today’s increasingly complex and risky internet system, Firewalls deserve more attention for the following reasons:Access control

Firewall is an important tool in controlling network access and protecting computer systems from threats from the Internet or internal network. Here are some key points about the role of firewalls in access control:

Prevent Unsuitable or Malicious Access: Firewalls can prevent unwanted connections or potentially malicious types of data from reaching the system.

Packet Filtering and Management: Firewalls can manage data packets traveling across a network by determining whether they are accepted or rejected. Packet filtering rules can be set up to allow only specific types of connections or prevent unwanted connections.

Protect against DoS and DDoS Attacks: Firewalls can help prevent types of attacks such as denial of service (DoS) attacks and distributed denial of service (DDoS) attacks by keeping traffic Unwanted people cannot compromise the system.

Connection and Port Management: Firewalls can control the opening, closing, or redirection of access ports. This is important for protecting network services and applications from external threats.

Keep the Internal Network Safe: Firewall not only prevents access from the Internet but also helps control connections and access within the internal network, preventing the circulation of unsafe data.

Virus prevention

For a small business, storing data, applications and services in the cloud requires a lot of effort, time and money. Therefore, choosing Cloud cloud storage service is a more suitable choice.
However, storing IT resources in the cloud also comes with many risks of information loss or data leakage due to cyber attacks or poor management of access rights to data. Therefore, maintaining a strict firewall policy is very important for customers, otherwise you may risk leaving your data exposed and dangerous to attacks.

Modern Firewalls can do more than just filter network traffic based on IP address. One of those features is detecting and preventing hackers and viruses in cyberspace.
In addition to hypertext transfer protocol (HTTP), which web browsers use to upload your web content, today’s most powerful firewalls also provide protection through Simple Mail Transfer Protocol (SMTP). That is, the firewall can check for viruses and dangerous attachments through your mail inbox.
