The role requires strong cloud and network security knowledge, hands-on experience with security tools, and the ability to lead strategic initiatives while coordinating with partners, vendors, and internal teams.
Responsibilities
- Implement network segmentation and Zero Trust to reduce attack surfaces, enforce least-privilege access, and isolate systems across enterprise and cloud environments.
- Lead the deployment, optimization, and upkeep of tools like EDR, AV, DLP, VPN, and firewalls to improve Arm’s security posture.
- Promote Zero Trust principles—identity-based access control, continuous verification, micro-segmentation, and clear trust boundaries—to limit lateral movement and protect key assets.
- Collaborate with architects and infrastructure teams to define segmentation policies that align with Arm’s threat model.
- Drive enhancements to security technologies, ensuring compliance with standards like NIST, CIS, and ISO 27001.
- Partner with IT and security teams to roll out new technologies and extend Zero Trust and segmentation across environments.
- Mentor analysts and engineers, promoting a culture of proactive defense and secure-by-design practices.
Required Skills And Experience
- Demonstrated ability in security operations, infrastructure security, or network security roles.
- Strong expertise in network security technologies, including VPN, firewalls, IDS/IPS, Zero Trust Network Access (ZTNA), and segmentation strategy and implementation.
- Technical proficiency in security solutions, including EDR, DLP, AV, email security, and cloud-native security controls.
- Experience implementing Zero Trust frameworks and network segmentation architectures in hybrid or multi-cloud environments.
- Understanding of Identity and Access Management (IAM) systems, including least-privilege access models, directory services, and policy-based access control. Familiarity with ITIL processes, security governance, and risk management, with experience tracking SLAs and compliance objectives.
Nice To Have Skills & Certifications
- Security certifications such as CISSP, CISM, CCSP, AWS Certified Security, or Cisco Certified CyberOps Professional.
- Experience with scripting and automation for operational efficiency (e.g., Python, PowerShell, Terraform), as well as modern Infrastructure-as-Code and Policy-as-Code frameworks.
- Familiarity with Zero Trust security models, segmentation technologies (e.g., SDN, NGFWs, NAC), and continuous risk assessment techniques.
In Return What You Get
