Saiful Islam

I’m a cybersecurity analyst with 3+ years supporting financial services and consulting environments, focusing on SIEM monitoring, cloud security, incident response, and vulnerability management. I align my work to NIST Cybersecurity Framework, ISO 27001, SOC 2, and SOX controls, with a strong emphasis on threat detection, security alert investigation, and security posture reporting.

At BNY Mellon, I analyze enterprise security alerts using Splunk SIEM, AWS CloudTrail, and Microsoft Defender for Endpoint, reviewing 1,800+ monthly security events and accelerating incident investigation turnaround from 4 hours to 95 minutes. I strengthen cloud protection with AWS IAM, AWS GuardDuty, AWS Security Hub, and Azure Security Center—resolving 240 high-risk cloud configuration issues affecting 12 production banking applications—and uncover 37 privilege escalation attempts using EDR telemetry and the MITRE ATT&CK framework.

I also secure regulated reporting environments using RBAC, network segmentation, and Tenable Nessus vulnerability scanning, resolving 118 critical security findings before 3 financial compliance audit cycles. I automate incident handling workflows with SOAR playbooks and PowerShell scripting, improving phishing response across 9 enterprise business units, and coordinate security posture reviews with cloud and application teams to guide remediation for 6 financial platforms processing 600K+ monthly transactions.
