• Design and develop security systems by establishing requirements for public key infrastructures (PKIs), including use of certification authorities (CAs) and digital signatures as well as hardware and software; adhering to industry standards.
• Design and develop security systems by specifying intrusion detection methodologies and equipment;
• Design security architecture elements to mitigate threats as they emerge.
• Create solutions that balance business requirements with information and cybersecurity requirements.
• Identify security design gaps in existing and proposed architectures and recommend changes or enhancements
• Align standards, frameworks and security with overall business and technology strategy
• Develop TOR’s and evaluate requests for information (RFIs) and requests for proposals (RFPs).
