Security Incident and Event Management

Unified Security Management (USM) Platform

CNS Mosaic Managed Services use a Unified Security Management (USM) Platform to provide log collections and SIEM.

Log collection is the ability to ingest log data into the system for automatic import and integration. This is a fundamental principle of the service because without it the current security posture of a network cannot be ascertained.

When an incident happens CNS is able to provide immediate visibility into the who, what, when, where, and how of an attack.

Event log data alone provides only pieces of this puzzle, without any context to make effective decisions.

code maintenance

The USM helps CNS move faster from raw event logs to actionable security intelligence by automating the event correlation process, providing every detail you need in the alarm such as:

  • Web service attacks (e.g. SQL injections, cross site scripting, etc.)
  • Client-side exploits (e.g. ActiveX, JavaScript, etc.)
  • Brute force authentication attacks (e.g. SSH, LDAP, NetBIOS, etc.
  • Distributed denial of service attacks (DDoS)
  • Malware detection (e.g. ransomware, Trojans, bots and more)
  • Common network attacks (e.g. IP spoofing, hijacking attempts, etc.)
  • Policy violations (e.g. anonymous proxy use, BitTorrent, P2P, etc.)
  • Other suspicious behaviour (e.g. login from Tor network)
