Firewall configuration: What is it? How does it work? Firewalls can greatly increase the security of enterprise networks, and enable organizations to protect their assets and data from malicious actors. But for this, proper firewall configuration is essential. Firewall configuration involves configuring domain names and Internet Protocol (IP) addresses and completing several other actions to keep firewalls secure. Firewall policy configuration is based on network types called “profiles” that can be set up with security rules to prevent cyber attacks. Schedule a demo Watch a video Firewall configuration challenges Configuring firewalls can raise many challenges Finding the right firewall It can be overwhelming to decide between a hardware or software firewall, so make sure you first determine your business needs and network configuration. Software firewalls can protect individual machines against harmful traffic; hardware firewalls are suitable for protecting enterprise networks. Broad firewall policy configurations During firewall setup, broad approvals policies that allow traffic from any source to any destination can expose the network to several security risks. It’s safer to implement narrow permissions from the start by following the Principle of Least Privilege (POLP). These firewall rule configurations can be widened later as required. Non-standard authentication With non-standard authentication methods, your firewall could accept weaker passwords or place less stringent limits on the number of login attempts allowed. This increases the risk of cybersecurity breaches. For safety, use only standard authentication methods. Open ports and risky management services Cybercriminals leverage open firewall ports and dynamic routing protocols to penetrate and exploit enterprise networks. Disable open ports at the time of firewall configuration. Other open ports should be adequately protected. Inadequate firewall monitoring If firewalls are not monitored, you may miss signs of unusual traffic that could indicate the presence of cyber attackers. Always monitor and log outputs from security devices so you will be alerted if you’re under attack. If an attacker does break through, alerts reduce the time to response. Guest or public networks: Use this profile when the system is connected to a public network. It’s best to set restrictive access because the other systems on the network could be potentially harmful. Private networks: Use this profile when connected to a network in workgroup mode. Set access to medium levels since the other systems can be mostly trusted. Domain networks: This profile is used when networks are connected to an Active Directory (AD) domain. A group policy controls the firewall settings. What are the network profiles for firewall configuration? A typical enterprise-level network is segregated into multiple security zones or “rings”: Ring 1: The Internet Edge Ring 2: The Backbone Edge Ring 3: The Asset Network Edge Ring 4: Local Host Security These zones are a logical way to group the firewall’s physical and virtual interfaces, and control traffic. Traffic can flow freely within a zone, but not between different zones until you define and allow it within the firewall policy configuration. In general, more zones means a more secure network What is the role of security zones in firewall settings? Yes, you can create a filter with a list of words, phrases and variations to be blocked. Configure your firewall settings to “sniff” each packet of traffic for an exact match of this text. Can I configure my firewall to block specific words or phrases? For each network profile, a firewall displays status information like: Profile currently in use Firewall state (On or Off) Incoming connections and current policy Active networks Notification state What information does a firewall display for each network profile? You can set firewall filters for all these protocols: Internet Protocol (IP) to deliver information over the Internet Transmission Control Protocol (TCP) to break apart and reconstruct information over the Internet HyperText Transfer Protocol (HTTP) for web pages User Datagram Protocol (UDP) for information that requires no user response File Transfer Protocol (FTP) to upload/download files Simple Mail Transport Protocol (SMTP) for sending text-based information via email Simple Network Management Protocol (SNMP) to collect system information from a remote computer Telnet to perform commands on a remote computer What are the protocols you can set firewall filters for? Here’s a 6-step secure firewall setup process: Secure the firewall Update with the latest firmware Replace default passwords with strong, unique passwords Avoid using shared user accounts Disable Simple Network Management Protocol (SNMP) or configure it securely Restrict incoming/outgoing traffic for TCP Create firewall zones Group assets into zones based on functions and risk levels Set up the IP address structure to assign zones to firewall interfaces Configure Access Control Lists (ACLs) Make them specific to the source and destination port numbers and IP addresses Create a “deny all” rule to filter out unapproved traffic Create an ACL (inbound/outbound) for each interface and sub-interface Disable admin interfaces from public access Disable unencrypted firewall management protocols Configure firewall logging Critical if PCI DSS compliance is a requirement Disable extra/unused services Test the firewall configuration Ensure the correct traffic is being blocked Perform penetration testing and vulnerability scanning Securely back up the configuration After you complete the firewall setup, manage and monitor it continuously to ensure that it functions as intended What are the firewall configuration steps?
