Industrial control systems (ICS) are the backbone of modern industry, managing critical infrastructure and processes. However, even the most robust security measures can become ineffective without consistent maintenance. This is where, controls sustainment, also known as operations support, becomes crucial, to overcome,

• Evolving Threats:

  Cybercriminals are constantly developing new attack methods. Sustainment activities like regular security assessments and system updates are mandatory in line with policies and procedures to ensure controls remain effective against the latest threats.

• Configuration Drift:

  Over the period, system configurations can unintentionally change, creating vulnerabilities. Sustainment programs help to identify and rectify these configuration drifts before they become exploitable.

• Proactive Maintenance:

  Regular maintenance not only optimizes system performance but also helps identify potential security weaknesses before they become critical issues.

At OSICS Technologies, we empower control system OEMs and end-users to achieve optimal performance through our comprehensive support services. We partner with you to establish a robust preventive maintenance program (PM) – including system hardening, OS updates, and network optimization – delivered through flexible call-off contracts or comprehensive SLAs. This approach minimizes downtime, and enables you to focus on core business activities.

Our team's expertise ensures you achieve your KPIs and maintain a secure, high-performing control system environment with the help of:

• Patch management:

  Unpatched vulnerabilities are open doors for cyberattacks. Our proactive patch management service keeps your industrial control systems secure by identifying, prioritizing, and deploying critical security updates. This minimizes the attack surface and ensures your systems remain protected against evolving threats.

• System Hardening:

  System hardening is your control system's suit of armour. By removing unnecessary features, tightening permissions, and keeping software updated, it minimizes the attack surface and makes it significantly tougher for cyber threats to infiltrate your system. This proactive approach strengthens system controls and helps ensure the continued reliability and security of your industrial operations.

• Access reviews:

  Periodic access reviews is critical cybersecurity control in line with industry best practices and typically mandatory requirement as per company security policies. This activity ensures only required personnel are continued to provide system access a. This process involves verifying that users still require access to specific systems and role, and removing access for those who no longer need it. By conducting access reviews, you minimize the risk of unauthorized access and data breaches, ensuring the ongoing security of your sensitive information.

• System backups:

  Regular system backups are essential part of disaster recovery. Offsite backups and system onsite backups are essential to restore the system in the event of failure or cyber-attack. We provide services to perform backups of all ICS systems including standalone systems which are unique within ICS /OT environment. We provide services to backup r critical data, configurations, and applications, allowing you to restore them quickly in case of system failures, cyberattacks, or accidental deletions. This ensures minimal downtime, data recovery, and a swift return to normal operations.

• User management:

  Robust user management is the cornerstone of industrial control system security. OSICS offers services to support management of ICS user access across the entire OT environment. This ensures only authorized personnel have access to systems as approved by system custodians while allowing segregation of duties, clear accountability, and at the same time strengthening the overall security posture. Security advisory reviews and corrective action implementation: Proactive security is paramount. At OSICS, we don't just identify vulnerabilities – we empower action. Our team meticulously reviews security advisories, pinpointing potential threats to your control systems. We then translate those findings into actionable steps, guiding you through the implementation of corrective measures that effectively mitigate risks and safeguard your critical infrastructure.

• Asset management:

  The first step in managing security program is to know the complete inventory of all operational assets. At OSICS we provide services to undertake discovery of all assets. Reliable asset inventory is a must to avoid any security gaps and legacy systems which often lack security compliance thus posing weak link providing backdoor for unauthorised access. It also helps to develop focussed vulnerability management to identify and address vulnerabilities efficiently.
