Types of Firewalls A Network Firewall is a device or software installed at the network perimeter. A Host-based Firewall controls the traffic that goes in and out of the computer. An Application Firewall protects web applications from known and unknown attacks. It monitors and controls traffic between an application and the network.
Why does Firewall Management Matter in Network Security?
- Firewall flaws are a common entry point for significant Cyber Security incidents. Cybercriminals can gain access via outdated firewall policies and rules.
- Firewalls are critical in shielding networks from cyber threats, malicious data breaches & viruses. They defend individual devices and the entire network from cybersecurity threats.
- A well-managed firewall assists in highlighting and mitigating cyber risks.
- The critical components of the management process are documentation and analysis. Firewall log analysis facilitates the detection and response to network threats.
What does Firewall Management involve?
Effective Firewall management involves the following:- Designing and implementing firewall policies.
- Monitoring the network traffic to detect any anomalies or attacks.
- Updating the firewall rules as needed to ensure continued protection.
- Maintaining the firewall hardware or software and installing updates.
- Ensuring the Firewall is well integrated with other security tools like IDS, Endpoint Protection Systems, SIEM, NMS etc.
- It may involve performing regular audits and risk assessments to identify vulnerabilities.
- Improves the security posture of the network.
Wrap Up
Organizations lose millions due to security breaches. Such breaches might occur due to lax configuration and subpar management measures. Firewalls play a critical role in protecting enterprise networks from unwanted intrusion attempts. Firewall configurations are vital aspects of Cyber Security standards. For instance, PCI DSS Regulations have firewall configuration as a core compliance component. A well-managed firewall reduces the chance of cyberattacks in the organization.
