Every business network is different, just as every network firewall security configuration is different. Our expert IT consultants understand that there is not one single solution for firewall security setup for every company. We will work with your team to ensure that an effective, achievable strategy is in place.
Firewall security solutions to protect your company from unauthorized access, breaches, and security attacks.
Network Firewall Security for Small Business & Enterprise
The network firewall is the first line of defense for traffic that passes in and out of a network. The firewall examines traffic to ensure it meets the security requirements set by the organization and that unauthorized access attempts are blocked.
The intention behind network firewalls is that they filter internet transmissions so that only traffic that belongs is allowed into an organization. Decisions are based on pre-set rules or policies. Like many areas of technology, firewalls have evolved greatly over time and are more sophisticated in terms of efficacy as well as flexibility of deployment.
For example, they have developed the ability to be deployed in completely virtual environments to protect data transferred to and from the cloud or to protect remote branches. "Firewalls have also greatly improved their ability to integrate threat defense and intelligence to protect against a range of threats including botnets, command and control servers, advanced persistent threats (APTs) and zero-day threats," said Mihir Maniar, vice president of Security Business and Strategy at Juniper Networks.
How Does a Firewall Work?
Firewall software monitors, restricts and regulates networks connections and communications on the perimeter of a private network with a public network. Often firewalls are used within organizations to partition traffic or data flows based on a categorization of information risk. Restricting traffic from potentially hostile connections on the internet is the major function of most corporate firewalls.
Additionally, it is quite common that access from corporate client connections to the internet are permissioned on a service-by-service (and often, client-by-client) basis as well. In this case, if a Stanford University user who is using such a corporate network connection to access Stanford University network services wishes to connect across this firewall, the relevant networking ports must be allowed along with their associated transport type.
Best Practices for Network Firewall Security
Every organizations' network configuration is different, just like every network firewall security configuration is different. Our experts understand that there is no one-size-fits-all security setup and work with your IT department or security team to ensure that a customized, effective plan is in place.
We follow best practices to ensure that every enterprise and SMB organization receives the best protection possible. This includes:
- Thorough documentation of firewall security protocols, responsibilities, and key roles within your company that help your team understand and keep security efforts organized.
- Revisiting and improving the firewall configurations in place to remain effective.
- Protecting any new technology that may be added to your corporate network setup over time, including adding special network firewall security software to employee mobile devices.
Firewall Security Examples
Implementing network firewall security can come in several different forms spanning hardware and software. These special devices restrict incoming and outgoing network traffic using specifically coordinated criteria, keeping any unauthorized users out of your secure network.
A hardware firewall is installed between your company’s network and the Internet to protect the systems inside - typically a router. For example, if a hacker tries to access your systems from the outside, your hardware firewall should be able to block it.
A software firewall only protects the device it is installed on. While computers may come preinstalled with certain anti-virus software firewalls, they often don’t have the same protection as something more robust. If an employee were to accidentally click on a phishing email, a software firewall should stop the malware in its tracks.
The best enterprise firewall protection uses a combination of hardware and software firewall security. The vulnerability of one alone is too great of a risk for enterprises and SMBs to take when it comes to data security. Using both a wired or wireless router (hardware firewall) and anti-virus and firewall protection programs (software firewall), businesses can reduce as many vulnerabilities as possible.
