Firewall Security Testing
Network Firewalls can present a boundary between the internet and a range of potential cyber threats and your internal business-critical devices.
Maintaining a securely configured firewall is often the first line of defence for your business and is crucial to prevent malicious traffic from targeting your business services.

Why Conduct A Security Assessment
Security incidents are often reported to have impacted over half of businesses and lead to costs and impacts which can be difficult to recover from. Assessments of your network security devices can help to provide assurance to your clients, peace of mind to your business owners, and to proactively address risks.
On average, over a hundred new vulnerabilities are disclosed each day, which may impact your firewall solutions.
When a business conducts security assessments of its firewall technology, it can uncover the vulnerabilities which impact your internal and external networks and help to identify solutions to improve your security posture.
Cyber Security has become increasingly prevalent as a client, partner and supplier requirement.
Firewall security reviews can evidence your commitment to cybersecurity, illustrate your proactive approach to security and demonstrate a seriousness to information security best practices, helping to maintain the confidence of existing clients and win new business.
Where a cyber security incident does occur, there are often several associated costs involved, such as the time and resources required for recovery, and any relevant fines and penalties which may be levied against your business for not managing information security effectively.
Conducting assessments against your firewall rules can identify the areas of risk within your business and help to produce a cost-effective approach and targeted strategy to address these security weaknesses.
Multiple compliance standards focus on your cyber security posture and how a business manages information security effectively.
Regular Penetration Testing has become a staple component of compliance requirements, and can be conducted to align with your certification standards, and improve your organisation’s overall reputation for the secure management of information security.
Benefits of A Security Assessment
Firewall assessments offer a range of benefits for your business to help improve overall security posture and gain a detailed knowledge of the real-world security risks from incoming and outgoing traffic.
Conducting a regular test of your devices and network traffic can highlight the risks which attackers may use to compromise credentials and gain unauthorized access to your business-critical systems.
This allows proactive steps to be taken to improve cyber security and resolve potential vulnerabilities.
Through conducting tests for the most common firewall security issues your teams can gain insight into your first line of defense and how insecure practices can introduce vulnerabilities into your systems.
This information can be used to guide improvements to enhance your cyber security, block malicious traffic and improve the security of your network connections.
The cost of a cyber security incident can quickly escalate due to downtime, reputational impacts, and information security fines. Implementing cyber security measures can also be a costly exercise if not focused on the areas which present a critical business risk.
Penetration testing services, can help to inform a vulnerability and risk management strategy, reducing the risk of an incident and targeting cyber security measures where needed.

Popular Questions
Network firewalls can be affected by several vulnerabilities which may impact your private network. As these devices can act as your first line of defense, it is important to ensure your firewall solution provides a level of protection against a number of risks, such as:
- Your Firewalls and network security devices may utilise outdated software to host their own services, and may present administrator and configuration interfaces to users over the internet.
- Firewalls make use of access control lists to filter and restrict incoming and outgoing traffic. These access control rules can introduce vulnerabilities into your network by exposing business-critical services and allowing access to sensitive data.
- Firewalls can often be configured to conduct multiple functions, such as deep packet inspection, web application firewall security, and act as an intrusion prevention system. Where these options are not configured in line with recommended security policies, it can introduce vulnerabilities to your business.
Next-generation firewalls can be vulnerable in many different ways and can therefore present a range of different risks to a business.
- Attackers will conduct reconnaissance of the different services which are exposed through your firewall and network perimeter, targeting insecure services which are made accessible.
- Bypass techniques identified within web application firewalls and other types of firewalls can allow malicious traffic to target your internal networks
- Missing security updates and misconfigured security policies can allow cyber threats to target your firewall directly, resulting in a compromise of your external and internal networks.
Where a security issue does occur, there are several aspects which can impact your business:
- The time required to recover from a security breach and restore your systems can incur costs such as recruiting people to aid in the recovery and the loss of business during any downtime.
- The ongoing impacts on your business reputation can impact current and potential clients’ likelihood to work with you, as it can be seen as a security risk.
- Fines and penalties can be levied against your business where a data breach occurs that impacts client data and personal data.
There are different benefits from both vulnerability scanning and penetration testing and each should be considered and applied for different reasons.
- Vulnerability scanners and automated tools are useful for speed and are cost-effective, allowing them to be run on a regular basis. This is useful to identify the latest available security updates for known vulnerabilities, and can help maintain your ongoing security.
- Penetration testing is useful for in-depth assessments, highlighting and contextualising API security vulnerabilities which scanning tools are often not able to identify. This can be useful when conducted on an annual basis, or after significant changes.
Although there can be several overlapping areas for security and testing techniques with an internal network test, firewalls have their own specific set of identified vulnerabilities and testing techniques, which can be followed to ensure your first line of defense are configured to a secure standard.
- Firewalls often present an internet-accessible target which may be targeted by malicious software. It is therefore important to ensure security policies are in place to protect private networks and limit potential access to network resources.
- Your firewall protects internal networks from internet traffic, and relies upon security rules to secure your IP Addresses. Consistent security policies need to be implemented to maintain protection and block malicious traffic.
- Your firewalls can be configured to control access, blocking unauthorized access to IP Addresses and network services which should not be accessed by incoming and outgoing network traffic. Access controls, configured to monitor network traffic can be utilised to detect threats and protect destination IP addresses.
There are a broad range of network security features which can be applied to your firewalls and packet filtering rules. The individual features can each play an important role in your business’s security system and provide a layered approach to your network security. Some of the most common features which are available include:
- Software Firewalls can offer essential security rules for your end user devices such as laptops, and desktops, providing security to your network traffic when not connected to your primary business firewall.
- Web Application Firewalls offer essential monitoring tools to protect your web services, identifying and restricting malicious software and network traffic which can be used to attack your external facing systems.
- An Intrusion Prevention System monitors network traffic for activity and behaviour which can indicate external threats and aims to block malicious traffic from targeting your IP Addresses and devices.
- Virtual Firewalls are set up and managed similarly to a traditional firewall but are managed as a virtual machine, often to manage and protect other virtual devices and cloud environments.
- Packet filtering firewalls are a standard and fundamental approach to network security. Firewalls are setup with access control rules, which review the network traffic which is transferred as packets. If the packet matches one of the allowed firewall rules, the data packets will be allowed to connect to their destination IP Adresses, however where there are no matching rules, or a specific deny rule, the connection will be refused or dropped by the firewall.
- Deep Packet Inspection (DPI), adds an additional level of security to standard packet inspection techniques, which only review information such as IP Addresses and Ports. DPI inspects the data which is transferred within individual packets and can be useful to monitor for malicious software and other types of external threats.
- A Stateful Inspection Firewall monitors network traffic and a connections status over time, allowing the connection to be dropped if deemed suspicious or for dynamic rules to allow related network traffic, such as responses to initial connections.
- Next Generation Firewalls offer additional features in addition to traditional network filtering, such as inspecting data packets, protecting against modern threats, reviewing allowed users or implementing intrusion prevention systems.
- Unified Threat Management consolidates multiple security solutions, which can be offered independently into a single, often cost-effective service. This can include firewalls, intrusion prevention, VPN’s, and antivirus software.
- Network Address Translation is a common feature of firewalls, allowing internal devices with a private IP Address to be translated into a Public IP Address, allowing businesses to control access to specific systems which are required to be accessible.
- Proxy Firewalls control communications between your internal users and the internet, allowing outgoing network traffic-based controls to be implemented and security rules to be applied based upon destination IP Addresses and preventing unauthorized access.
