- Evaluation & Deployment: Participate in the evaluation, proof-of-concept (PoC) testing, selection, and implementation of new security tools and technologies to continuously enhance the overall security posture.
- Incident Response & Log Analysis: Review security logs and reports to identify patterns or anomalies that may indicate potential security breaches; respond to and resolve security incidents in a timely manner.
- Documentation & SOPs: Assist in developing and maintaining comprehensive security documentation, including standard operating procedures (SOPs), user guides, and knowledge base articles to facilitate effective tool utilization and support.
- Training & Support: Provide technical support and training to end-users and other IT teams on the proper usage and maintenance of security tools.
- Cross-Functional Collaboration: Partner with vendors, internal stakeholders, and cross-functional teams to ensure security policies and procedures are followed and technical issues are resolved efficiently.
- Operational Flexibility: Support operational needs, which may require flexible working hours, shift schedules, or weekend/holiday coverage, while maintaining a standard 5-day in-office work week.
