Organizations around the world must combat the growing threat of drive-by cyber attacks. Firewall appliances are often configured as the first line of defense against malicious attacks like malware or ransomware, and installing a firewall is the first step in securing your network.
Once your firewall is up and running, your IT team must properly configure the device so that critical services can get through while unwanted connections are explicitly denied. How can your organization get the most out of its firewall? Let’s take a deeper look at the most powerful features of common firewall appliances.
Just about every employee will sooner or later distract themselves at work by browsing their favorite websites, playing games, or streaming television or music. Salary.com reports that 61% of employees who participated in a recent survey admitted to wasting between 30 minutes to an hour at work each day. Properly configuring content filtering options will take away the urge for employees to browse the internet on the company’s dime.
From an information security standpoint, organizations that house sensitive data should always have some sort of content filtering policy enabled. Without content filtering, the attack surface of your organization grows exponentially. Seemingly innocent websites such as MSN nd Forbes have unknowingly served malware to their visitors after a group of hackers compromised the advertising platform that was embedded into each of these websites.
Most firewalls give administrators the ability to pick and choose the categories of websites that can be displayed on company PCs. For example, if you blocked the email category, your users would not be able to login to email service providers such as Gmail, Office 365 or Yahoo Mail.
Most modern firewall appliances have an intrusion prevention feature baked into the platform that prevents known cyber attacks from happening on your network. Perhaps you have a public facing web server that clients use to transmit, fetch or store data.
Servers facing the outside internet are frequently scanned by penetration testing scripts. If your servers are vulnerable, these pen testing scripts provide hackers with an easy method of compromising your server and causing harm to your network.
When you configure your firewall using intrusion prevention policies, your network can automatically deflect and defend against known cyber attacks. Intrusion prevention is typically an add-on service for many firewalls, so be sure to confirm that your firewall will have it. Most firewalls will automatically reach out to the manufacturer’s database to grab definition files that are updated daily.
Ready to take control over the connection attempts into your network? Firewalls provide your IT team with the ability restrict both inbound and outbound network traffic. Administrators can easily block specific IP addresses by setting up a firewall rule. These rules can be granularized to only allow connections on specific ports.
These robust features provide administrators with the ability to keep harmful traffic out of their network while simultaneously providing legitimate traffic a prioritized route to the packet’s final destination.
The most overlooked feature is often the logs. The easiest way to detect and a prevent a cyber attack is meticulously evaluate this documentation. If a malicious attack is launched against your network, your firewall logs will serve as the forensics evidencing the payload of the attack. Many firewalls can be setup to email alerts to administrators when specific events occur.
Many system administrators have automated the task of sifting through these logs. Sophisticated 3rd party tools are available to help your organization rapidly make their way through all the logs your firewall devices generate. These apps can prove to be extremely helpful, should your organization consist of several firewalls networked together in a site to site VPN configuration.
