What is a Firewall: Virus Removal for your Small Business

Building an network to store information and facilitate communication can be advantageous for small businesses. The downside is that any sensitive information flowing through the Internet is extremely vulnerable to online threats. Firewalls are key for small business’ strategy for network security, and therefore a key aspect of network setup. A network firewall benefits a small business by offering an extra layer of support against threats for multiple servers across a network. Companies with a network firewall define their own security parameters by restricting access to certain sites, thereby thwarting hackers, viruses, and worms. Even if a hacker manages to break through a network firewall, he or she will still face the entirely new challenge of gaining access to the host.

Rather than covering large (or several) networks, host-based firewalls protect a single computer. Only those with direct access to the physical device will be able to partake in host-based firewall setup. Network and host-based firewalls function in different ways, but serve the same ultimate purpose: keeping your computer safe. Ultimately, the best choice for any modern small business would be to employ both devices. After all, even the slightest vulnerability poses an open invitation to online threats. A credit card breach can cost the average small business upwards of $36,000. It is important to note that while firewalls block malicious traffic, antivirus software is responsible for the actual removal of computer viruses. Together, firewall and antivirus software will render your small business virtually impenetrable to online threats.

Network Firewall

Network firewall for small business

Every small business needs a firewall in order to ensure safe browsing, data sharing, and general network security between and within networks. Firewalls prevent pop-ups, malware, cookies, and e-mail viruses from infecting your small business network/computer. Operating a small business without strong fortification is a serious risk. A combination of network and host-based firewalls (plus antivirus software) can mitigate these dangers, warding off hackers and keeping confidential company information safe and secure. The most rigorous firewall systems make it possible to set up encrypted remote connections. In other words, small business owners and employees can browse securely whether they’re at work or at a remote location.

Firewall Setup for your Small Business

Firewall setup is quite simple. Software firewalls – which protect only the device to which they have been downloaded - can be purchased online at relatively low price. There are dozens of firewall options from which to choose. Some websites even offer firewall software for free, and certain computers come with firewall software already built in. While these are certainly viable routes, it is necessary to note that more expensive varieties are typically more comprehensive, and contain antivirus features. A software firewall alone will protect your small business; but in order to make your network as secure as possible, it is important to install some sort of hardware appliance wherever there is a main Internet connection. Most Internet routers contain built-in firewalls. In this instance, firewall setup is as switching the “on” button. A combination of both software and hardware firewalls will ensure optimal protection for your small business.
