Senior Security Analyst

Responsibilities:

  • Securing the Incident Response process by vetting undetermined yet apparent links in the threat-killchain. Protecting the global WAN/LAN from areas of compromise such as: malware, APT groups, internal asset, misuse, and improbably identifiable threats by conventional IPS
  • Perform digital forensics in incident response using common freeware tools. Examining host to further develops IOCs for internal use, reporting, and threat vectoring.
  • Proficiency in power shell scripting to add to an already developed skill set in windows command line and debugging tools.
