Security Compliance & Auditing: Monitor and report on the status of encryption and network security controls. Conduct regular reviews to ensure that all hybrid and cloud-based configurations meet organizational security policies and industry regulatory requirements.
Vulnerability & Risk Mitigation: Identify and remediate security gaps in the hybrid network infrastructure. This involves assessing the risks associated with data movement between environments and implementing hardening measures to protect against unauthorized access or data leakage.
Incident Response Support: Provide subject matter expertise during security incidents involving encryption failures or unauthorized network access. Assist in the rapid revocation and replacement of compromised credentials to restore secure operations.
