    CYBERSECURITY POSTURE EVALUATION


    According to NIST, the security posture is:
    “The security status of an enterprise’s networks, information, and systems based on information security resources (e.g., people, hardware, software, policies) and capabilities in place to manage the defense of the enterprise and to react as the situation changes.”
    To react to an always growing and challenging threat landscape we strongly suggest to measure and keep under control your cyber security posture. We might help you with the following services:
    • Gap analysis of your CSMS against reference security standards from your domain.
    • Identification of your Enterprise attack surface.
    • Evalutation of the potential threats you are facing.
    • Overall Risk exposure quantification.







     

    THREAT ANALYSIS AND RISK ASSESSMENT


    Threat analysis and Risk assessment is a key step towards a secure system architecture.

    Our cybersecurity experts will assure valuable results by leveraging the following points:
    • Deep knowledge of the threat landscape related to your domain.
    • Clear identification of the system under analysis, its border and its assets list.
    • A complete identification and evaluation of System and products vulnerabilities.
    • Full comprehension of the impact of each potential threats to your business.
    • A Sound model based enabled methodology to handle the process.







     

    DEFENCE IN DEPTH ARCHITECTURE DESIGN


    To keep the all unauthorized person away from your systems you must let their life to be as much difficult as possible.

    System networks and subnetworks shal be organized according to the defence in depth approach that foresees multiple layer of security with multiple and different security solutions in place for each layer.
    Resiltech has the expertise to support you in the design of a new ICS system architecture or in the identification of additional measure to strengthened what is already in place.
