Securing Manufacturing company on AWS with Palo Alto Next-Gen Firewalls
Palo Alto & AWS: A Dynamic Duo for Manufacturing Security Reinvention | Case Study
In a strategic move, an established Manufacturing company shifted a segment of its digital infrastructure to AWS. The goal was to enhance connectivity with numerous suppliers and wholesalers engaged in daily business transactions. With numerous orders and third-party transactions at play, stringent security measures were imperative. The challenge was to ensure not only security but also granular inspection facilitated by Multi-Factor Authentication.
Additionally, the AWS environment had to meet the demands of scalability and redundancy and handle sudden spikes in demand during busy periods.

Objective
The existing environment posed challenges: it lacked a security-first design and scalability. Growing organically, it faced hurdles like difficult-to-manage Network Access Lists (NACLs) and limited resiliency due to applications in the same Availability Zone. Moreover, the AWS architecture fell short of compliance, lacking proper access limitations and network segmentation, along with security vulnerabilities.
Our objective was clear: enhance the system’s security and compliance. We addressed gaps, revamped infrastructure, and ensured adherence to standards. This included refining access controls, segregating networks, and implementing fault tolerance and monitoring mechanisms, providing comprehensive assistance for a robust, compliant AWS solution.
What was done
To meet the Core requirement, we deployed Palo Alto in High-Availability mode, surpassing client expectations. The network architecture was optimized, featuring separate VPCs for Prod/OAT/TestDev, segregated Public/Private Subnets, and strict inbound/outbound traffic filtering via the Palo Alto Firewall. Additionally, we implemented Multi-Factor Authentication for end-user access, ensuring a near 100% success rate while eradicating unauthorized login attempts.
Furthermore, a robust central logging solution, utilizing AWS Elasticsearch and CloudWatch, enabled comprehensive system audits through AWS CloudTrail. We developed a monitoring solution gathering metrics from all VPC services and instances, enhancing insights. We fortified security by installing and updating anti-virus and vulnerability detection software in all instances, ensuring a robust shield against potential threats.
Achievement
The Company’s security standards significantly improved post-adjustments, resulting in a fault-tolerant, data theft-protected infrastructure for safeguarding both internal and client data. Palo Alto firewall played a pivotal role by efficiently denying and logging malicious traffic, ensuring a resilient defence against potential threats.
