Firewalls are like security checkpoints; they monitor information going in and out of a network. If you’ve installed a firewall on your business system, congratulations! But is your business firewall enough to protect you from cyber-attacks?
Hardware vs. Software
First, what kind of firewall did you install? You may have a physical unit, a hardware firewall, sitting between your router and your server. This firewall filters incoming data packets, allowing only the information that meets specific criteria to enter your network. Modern firewalls also examine outgoing data, applying permissions to prevent hackers from using your computers to send malicious code to other devices on the internet.
Software firewalls also examine incoming and outgoing information, but the software firewalls sit on your computers as applications. This software usually requires a monthly subscription fee, and all computers must be updated regularly to the most recent version. In addition, these applications also use some of your devices’ resources.
While there are pros and cons to both kinds of firewalls, neither one may give you all the security you need.
External vs. Internal Threats
Your firewall protects your system from external threats by restricting unauthorized entry. These external threats include malicious attacks from sources outside your network. If a hacker has gained entry to your network and attempts to send out malicious code from your computers, your firewall can also attempt to prevent the distribution of the code.
Internal threats, on the other hand, relate to security breaches from inside your network. From time to time, a disgruntled employee may attempt to sabotage your system, but internal threats often originate from unsuspecting employees falling prey to phishing schemes, trojan horses, spyware, or other malicious attacks.
Firewall vs. Antivirus Software
Your firewall protects your network from external menaces, but you need antivirus software to capture, disable, and alert you to internal threats. There is good news – some providers bundle antivirus software with firewall software. Some modern solutions offer Cloud-based, SaaS, firewall, and antivirus protection.
You can also add antivirus software to work alongside your current firewall. In summary, you need both firewall and antivirus protection to adequately secure your network. You may not have the time or the expertise to assess your need. A Managed Service Provider can help you.
