Network Security Operations Engineer
Encora, Kuala Lumpur
About the job
We are seeking a hands-on Network Security Engineer to operate and continuously improve our network security stack—primarily enterprise firewalls (Palo Alto, Fortinet, Cisco), secure web gateways/proxies, and site-to-site/remote-access VPNs. The ideal candidate is an operator-engineer hybrid with deep knowledge across L2–L7 security controls, strong troubleshooting skills, and proven experience in high-availability, low-latency environments. Experience supporting MAS TRM or BNM RMiT audits is highly preferred.
Operations & Reliability
Own day‑to‑day operation of Palo Alto, Fortinet, and Cisco firewalls, Proxies, and VPN appliances (IPSec/SSL). Monitor and maintain HA clusters, dynamic routing (BGP/OSPF) on firewalls, and NAT/policy objects to ensure availability and performance SLAs. Execute change management: rule modifications, NAT adjustments, SSL decryption policies, URL categories and app‑ID signatures. Perform break/fix troubleshooting using methodical, packet‑level analysis (pcaps, flow records, session tables, global counters).
Security Engineering & Hardening
Manage segmentation (zones, VRFs, tags), east‑west and north‑south controls, and zero-trust policy baselines. Develop and maintain standardized security templates (objects, groups, security profiles, threat/vulnerability profiles, URL filtering, DLP where applicable). Tune IPS/IDS, Anti‑Malware, URL filtering, WildFire/ATP, DNS Security, and sandboxing controls to reduce false positives while maintaining strong coverage. Integrate firewalls with identity (AD/LDAP, IdP, SSO), SIEM/SOAR, PKI, and EDR/XDR telemetry to enrich detections and automate response.
