A firewall is the first line of defence against online attacks, making it a critical part of your network security strategy.
In a networked environment, a firewall is the first line of defense. For organistions that do not deployed multi-layered security mechanisms, firewall protects your network traffic based on different categories (viruses, network floods, malicious URLs).
A firewall review involves checking the configuration of the device including review of rule base. During the review, Defendza consultants seek understanding of network design, firewall function, business requirements before the review. This helps in understanding and assessing the firewall configuration with a balanced view to keep into account realistic attack scenarios.
Network traffic allowed through the firewall must be in line with functional requirements. Defendza have experienced contrary situations where either service provider or customer's IT team have temporary changes, duplicate rules, large/excessive attack surfaces been allowed.
Whether it's business as usual review or after changes, it's important to find out weaknesses in your firewall configuration and rulebase to identify gaps. These gaps could aid an attacker to initiate unauthorised connections to outside systems in order to exfiltrate data, set up command and control channels or other malicious actions.
We take customer communication as seriously as reporting or assessment execution. We engage with customers during all stages, and ensure that customer contacts are up to date in the language they understand. Post engagement, a free debrief is conducted to help the customers understand the weaknesses and prepare a mitigation plan.
The assessment-execution phase is followed by the analysis & reporting. Defendza performs analysis on the testing output, evaluates the risk impact and likelihood of exploitation in realistic scenarios before providing action plans to remediate the identified risks. All our reports address business as well as the technical audience with supporting raw data, including mitigation measures at strategic and tactical levels.
Firewall ruleset review involves understanding the traffic flows between different network segments. This process includes working on the following objectives:
A firewall configuration review checklist concentrates around the following areas:
Our reports are comprehensive and include all the evidence that supports our findings. We give you a risk rating that considers how likely an attack is as well as the impact it could have. We don’t create panic scenarios. Our mitigation is detailed, covering both strategic and tactical areas to help our clients prepare a remediation plan.
Apart from the range of commercial and open source tools available for specific testing, our team has its own custom scripts for efficient testing. We provide accurate results to make sure our clients completely understand any vulnerabilities we report.
Our teams are led by veteran security consultants accredited by CREST standards for the last several years. Our experience shows that our clients are best served by giving them the right advice for their cyber security needs. We do not believe in spreading fear, uncertainty and doubt to generate more business.
Much of the manufacturing industry has failed to take proactive steps to defend against cyber attacks—which is a notable problem considering the growing threats the industry faces
