  • End point alert / HIPS / Host based malware alerts for local script execution for the same user, raise incident
  • Identify usual traffic volumes to multiple ports or IP addresses or excessive packet loss (connection over 4 hours to external IP )
  • Examine abnormal services on known ports and abnormal ports for well-known services, verify reputation scores of IP (SSH to port 80)
  • EDR and WAF alerts for scripts, hash mismatch
  • Botnet filter alerts for traffic to blacklisted domains
  • Email / SPAM filter misbehavior / maintainance activity followed by suspicious activity on the network specially related to unknown / suspicious remote destinations
  • Monitor packet flow inside and outside from the network for likely patterns of Command and Control (C + C) traffic, outbound custom encrypted communications, covert communication channels with external entities etc.
  • Threat intelligence alerts for connections / data sent to suspicious destination outside organization specially belonging to less reputed geographic location and at odd hours
  • Examine if any data breach has occurred like large HTML packet
