Security and Risk Management

Integral and continuous process

 

Governance, Risk & Compliance (GRC)

Cyber security must not be patchwork, but requires the frame of an integral security management from security conception to compliance of regulations up to estimation of residual risks.

PDCA Concept

The BSI-Standard 100-1 for Information Security Management Systems (ISMS) as per ISO 27001 recommends the well-proven PDCA concept (Plan, Do, Check, Act) for all IT security processes.

3 Posts of Security

  • Technical measures
  • Physical measures
  • Organisational measures

"Plan" and "Do"

Plan and realise the use of our innovative INSYS routers with effective security features like for manipulation protection for example.

"Check"

Check the e.g. the following using the INSYS routes:

  • unauthorised access attempts at the web interface
  • each change of configuration
  • connecting and disconnecting a device at the Ethernet switch (link up, link down) 
  • the receipt of IP packets from an unknown device (statefull firewall)

 
"Act" 

Benefit from the "duress alarm" and act since our routers inform you immediately - a later evaluation of the log file might literally be too late.

Policies & Procedures

Only the interaction of technical, physical and organisational measures as well as their regular check and update provides maximum security; raising the awareness of the employees is only one of many factors of success. This is based on clear guidelines and processes.

INSYS icom routers support the processes recommended by the BSI. Moreover, they meet the concepts of the BDEW White Paper and are based on the Associated Execution Notes.
