Preventing a Major Ransomware Attack
🚨 Challenge Snapshot
â—† Spike in phishing emails and malicious attachments targeting employees and shared mailboxesâ—† Increased exposure from unmanaged endpoints, outdated patches, and inconsistent security baselines
â—† Limited visibility into suspicious lateral movement, privilege escalation, and abnormal file activity
â—† Need to prevent business disruption and downtime while keeping operations running smoothly
🛠️ What KIS Implemented
â—† Rapid ransomware readiness assessment: critical gaps identified across email, endpoints, network paths, backups, and privileged access
â—† Identity & access hardening: MFA enforcement, privileged access tightening, conditional access rules, and removal of excessive admin rights
â—† Endpoint security uplift: EDR rollout/tuning, ransomware behavior detections, isolation workflows, and secure baseline hardening
â—† Network containment controls: segmentation improvements, firewall policy hardening, and restrictions on lateral movement paths
â—† Email security enhancement: anti-phishing and anti-impersonation controls, attachment/URL protection, and safer email handling
â—† Monitoring + response readiness: key telemetry onboarding, ransomware-focused detections, and IR playbooks (containment, eradication, recovery)
âś… Results (Business Impact)
â—† Prevented ransomware execution and stopped early-stage intrusion activity before encryption could occur
â—† Reduced attack surface through improved patch hygiene, hardened configurations, and tighter access controls
â—† Faster detection and containment with clear visibility across endpoints and critical systems
◆ Improved operational resilience with validated response actions and recovery readiness—minimizing downtime risk
