Components of a strong firewall include:

* User identification and access management
* Credential theft and abuse mitigation
* Application and control function safety
* Encrypted traffic security
* Advanced threat defense and cyberattack prevention
* Mobile workforce protection
* Cloud environment security enhancement
* Management centralization and security capability integration
* Task automation and threat prioritization

## User Identification and Access Management

Identification and access management are critical in an effective firewall. These mechanisms ensure only verified users can access the network by granting the appropriate level of permission. As individuals use various devices to connect, distinguishing users becomes crucial. A robust firewall identifies users beyond their IP addresses by considering the risks associated with the devices in use. This goes beyond traditional firewalls that may focus solely on IP addresses to consider the entirety of the user's context, including their location and device.

![A diagram of an IT network showing various devices connected to cloud services, internet, and a data center.](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/what-makes-a-strong-firewall/users-access-data.png)

Users changing locations or devices test a firewall's ability to maintain security protocols. Traditional IP subnet methods cannot track these changes at the user level. Consequently, a firewall must integrate user and group data to adhere to security protocols regardless of user movement. This integration pulls from various sources like virtual private networks (VPN), WLAN controllers, and directory servers to provide a comprehensive view of network activity.

Policy enforcement within a firewall should be user centric. It should allow certain applications to be accessible to specific users or groups. Whether a user connects from the office or remotely, the policies linked to their identity should remain consistent. This ensures the internal network remains secure, and the security team can swiftly address any unusual activity.

[What Is a Firewall?](https://www.paloaltonetworks.com/cyberpedia/what-is-a-firewall?ts=markdown)

## Credential Theft and Abuse Mitigation

In the [network security](https://www.paloaltonetworks.com/cyberpedia/what-is-network-security?ts=markdown) landscape, credential integrity is essential. Many data breaches involve compromised privileged credentials. Once in the hands of unauthorized users, these credentials can increase the risk of network breaches and decrease the likelihood of detecting the attackers. Methods like phishing, malware, and social engineering are common ways attackers acquire credentials, which they use to infiltrate networks and escalate access privileges.

Firewalls act as a gatekeeper, using advanced mechanisms to prevent credential theft and abuse. By monitoring traffic by default, firewalls can identify and mitigate threats, stopping unauthorized users from exploiting credentials to gain network access.

Traditional measures against credential theft include user training, password policies, and security products for email filtering. While these practices contribute to security, they have varying effectiveness. Sophisticated phishing and social engineering techniques, as well as inherent static password weaknesses, make clear the need for advanced security mechanisms. Firewalls enhanced with machine learning analytics can help identify and block malicious websites in real time.

![Multifactor authentication components: knowledge, possession, inherence.](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/what-makes-a-strong-firewall/multifactor-authentication.png)

A strong firewall employs multifactor authentication (MFA) to bolster defenses against credential misuse. MFA implementation typically involves a combination of something known, like a password, and something possessed, such as a smartphone or token. It significantly reduces the chances of unauthorized access because even if an attacker steals credentials, they still need the physical authentication device. An MFA system sends a code to the user's device, which is necessary for login and valid for a single use within a short time frame. Even if an attacker intercepts the code, it invalidates after one use, safeguarding the network.

## Application and Control Function Safety

Effective firewalls must manage application usage with precision. Users often access a variety of applications across multiple devices and networks for both professional and personal use. These applications may have features that can pose security risks, such as the ability to operate on nonstandard ports. Firewalls need to discern and manage such applications, which vary in how organizations classify them: sanctioned, tolerated, or unsanctioned.

![Icons for applications including download, upload, posting, A/V, accounts, file transfer, remote control, and sharing.](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/what-makes-a-strong-firewall/control-application-usage-in-policy.png)

The firewall should have the capacity to identify and control incoming and outgoing traffic consistently across all ports. This includes monitoring application features and functionalities that carry different risk levels. For instance, while certain applications like email and document sharing provide essential services, they also have features that could breach internal or regulatory standards if misused. It is necessary for a firewall to maintain granular control over applications to ensure compliance with corporate policies.

Continuous monitoring and dynamic control of application functions are essential. Applications may switch functions within the same session, and the firewall must be able to reassess policies in response to such changes. Stateful tracking of applications and their functions allows the firewall to recognize and mitigate associated risks, ensuring a secure network environment.

## Encrypted Traffic Security

![A diagram showing steps for encrypted traffic security, from risk detection in SSL/SSH to adhering to privacy regulations.](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/what-makes-a-strong-firewall/encrypted-traffic-security.png)

A robust firewall must be capable of managing encrypted traffic based on security policies to secure web communications. While vital for protection information, attackers can exploit Secure Sockets Layer (SSL) encryption to conceal threats. Monitoring SSL encrypted traffic is necessary even for internal networks with otherwise extensive security measures.

Secure Shell (SSH) encryption is also common, sometimes used to obscure non-business-related activities.

The decryption of SSL and SSH encrypted traffic is a crucial capability of a strong firewall. It should recognize and decrypt external network traffic on any port and offer policy control over which traffic to decrypt. To handle the demands of decrypting numerous SSL connections simultaneously, the firewall requires the right combination of hardware and software, designed for high performance.

Flexibility in handling encrypted traffic is also key. Firewalls configuration should allow for the decryption of certain encrypted communications, such as HTTPS from non-sensitive websites, while respecting privacy regulations by not decrypting traffic from known financial institutions. In addition, a firewall should enable security policies and load balancing on decrypted traffic, facilitating additional security measures without the need for separate SSL decryption hardware.

## Advanced Threat Defense and Cyberattack Prevention

An effective firewall must provide advanced threat defense to prevent cyberattacks. Malware often employs complex methods to evade detection by security systems. Attackers have developed means to circumvent dynamic analysis, such as detecting virtualized environments or monitoring for user activity, making it crucial for firewalls to adapt continuously.

Integrated security services within a firewall should block known threats and analyze unknown threats to offer proactive protection. A strong firewall observes the entire attack lifecycle, preemptively blocking risky file types or access to known malicious sites. It should autonomously update its threat signatures, maintaining robust defense against evolving threats without reliance on additional single purpose security tools.

![Icons depict stages of an attack lifecycle: vulnerability exploit, malware installation, command/control, lateral movement, data exfiltration.](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/what-makes-a-strong-firewall/attack-lifecycle.png)

A multifaceted approach to threat detection is key. Firewalls should employ static and dynamic analysis, supplemented by machine learning, to detect sophisticated threats. Content based signatures, rather than attribute-specific ones, enable the identification of polymorphic malware and command-and-control patterns. Cloud based security infrastructures play a crucial role in this, allowing for scalable threat detection and prevention across various environments.

## Mobile Workforce Protection

![A diagram showing a mobile workforce protection strategy with connectivity and security layers.](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/what-makes-a-strong-firewall/mobile-workforce-protection.png)

Strong firewalls must offer protection for a mobile workforce. As mobile device usage increases among remote employees, the risk of exposure to advanced threats also rises. When employees are outside the traditional network perimeter, they lack the inherent protections a network firewall provides, heightening vulnerability to cyber threats. The prevalence of cloud services and the trend of bring-your-own-device (BYOD) further complicate securing these devices.

Workers need access to business applications from various locations, along with robust defense against cyber threats such as targeted attacks, malicious software, and phishing attempts. Achieving consistent security across various locations demands a firewall that provides comprehensive visibility, threat prevention, and policy enforcement. This level of protection should be deliverable from the cloud, obviating the need for physical hardware deployment at remote sites.

## Cloud Environment Security Enhancement

![Cloud environment security: multicloud, cloud services \& automation integration, policy enforcement](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/what-makes-a-strong-firewall/cloud-environment-security.png)

Businesses are increasingly hosting sensitive data on various cloud platforms, necessitating robust security measures beyond the network perimeter. Traditional security tools designed for static networks often fall short in cloud environments. Furthermore, security services provided by cloud platforms typically offer limited protection and are not universally applicable across different providers.

A firewall must extend consistent policy enforcement from the network to the cloud, preventing malware from infiltrating and propagating within data centers and cloud infrastructures. It should facilitate simplified management and quickly adapt to changes in virtual workloads. For multicloud strategies, compatibility with all major cloud services is necessary, ensuring the security posture in the cloud matches that of the physical network.

Integration with cloud native services and automation tools is crucial for modern firewalls. This integration allows for seamless security within cloud development projects, providing protection for applications and data regardless of their cloud environment. Firewalls must support a range of virtualization options and work in tandem with services like AWS Lambda and Azure, as well as automation tools such as Ansible and Terraform.

## Management Centralization and Security Capability Integration

Centralized management in firewalls is essential for streamlined operations. Security products often come with their own unique management interfaces. Using multiple products from different vendors can lead to disjointed security protocols. Centralization consolidates various management tasks, making it easier for security operators to oversee the network.

Maintaining a consistent security stance across a large array of firewalls is a substantial challenge. This is especially true in complex networks that span multiple locations and cloud environments. Centralized management is critical for the efficient deployment and maintenance of uniform security policies. A single management console can offer visibility into all network traffic, facilitate configuration management, policy application, and detailed reporting on security and malicious traffic events.

![Centralized Management](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/what-makes-a-strong-firewall/centralized-management.png)

Given the diverse nature of threats and the need for agile responses, firewalls must integrate with a variety of security services and insights. When a firewall delivers capabilities from the cloud, security teams can more effectively prevent threats across the network. Integration with third party services is also essential. Integration allows the incorporation of external intelligence and innovation into the security framework. This interoperability is a key consideration when assessing future security solutions.

## Task Automation and Threat Prioritization

A strong firewall must incorporate task automation and prioritize threats effectively. The cybersecurity sector faces a skills shortage, compounded by reliance on manual security operations. Manual efforts in data analysis and false positive alerts management are inefficient and prone to errors, often leading to missed critical threats. It is imperative to source and prepare data from all facets of an organization's digital presence for analysis.

Big data analytics requires precise data to generate actionable intelligence. As the demand for cybersecurity professionals grows, the importance of automating routine tasks and focusing on essential threats increases.

![3 strong firewall capabilities: workflow automation, policy automation, and security automation](https://www.paloaltonetworks.com/content/dam/pan/en_US/images/cyberpedia/what-makes-a-strong-firewall/three-capabilities-of-strong-firewalls.png)

To address these challenges, firewalls need to automate workflows, policies, and security tasks. They should offer standardized APIs for integration with other tools. Firewalls should also enable automated policy adaptation to environmental changes, including application mobility and threat intelligence integration. By automating threat detection and response, firewalls can help in discovering concealed threats.
