Ocala Florida Firewalls

What Is A Firewall?

A firewall is a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules. Firewalls have been a first line of defense in network security for over 25 years. They establish a barrier between secured and controlled internal networks that can be trusted and untrusted outside networks, such as the Internet.  A firewall can be hardware, software, or both.

Firewall FAQs

Is a firewall necessary?
When you are connected to the internet (which for most users is 100% of the time), there are all kinds of little bugs and bots and malicious people that would like to get into your computer and take a look around. You don’t want any of these bad things having access to your computer.

Second – do you really need a firewall? Yes, you do need a firewall.

What Type of Firewalls Exist?
Packet filtering: The system examines each packet entering or leaving the network and accepts or rejects it based on user-defined rules. Packet filtering is fairly effective and transparent to users, but it is difficult to configure. In addition, it is susceptible to IP spoofing.

Circuit-level gateway implementation: This process applies security mechanisms when a TCP or UDP connection is established. Once the connection has been made, packets can flow between the hosts without further checking.

Acting as a proxy server: A proxy server is a type of gateway that hides the true network address of the computer(s) connecting through it. A proxy server connects to the internet, makes the requests for pages, connections to servers, etc., and receives the data on behalf of the computer(s) behind it. The firewall capabilities lie in the fact that a proxy can be configured to allow only certain types of traffic to pass (for example, HTTP files, or web pages). A proxy server has the potential drawback of slowing network performance, since it has to actively analyze and manipulate traffic passing through it.

Web application firewall: A web application firewall is a hardware appliance, server plug-in, or some other software filter that applies a set of rules to a HTTP conversation. Such rules are generally customized to the application so that many attacks can be identified and blocked.

Is a Firewall Expensive?
Good news is firewalls are very affordable. Depending on the model and security software it can be as low as $50/month! Our firewall expert will discuss which model is your best fit.
Is Anti-Virus Enough?
Having multiple layers of protection is the best method to ensure security on a network. Anti-virus on your PC is great to have in case someone uploads a file onto your network, or if the website was hacked and a trojan was installed.

Fact is, reactive software is not enough to prevent a full network meltdown. A firewall PLUS software can ensure your are covered both internally and at the entrance to your network.

What Happens After Installation?
Your new firewall will work 24×7 checking your network for incoming and outgoing suspicious packets of information. Blocking or allowing websites and files according to the policy we set for the office.

Since the firewall is at the modem, you can block websites like Facebook or Twitter so employees work while at work. There are many other settings to choose from. Speak to our firewall expert for details.
