Security experts at Arishti have years of experience in conducting
security assessments on various industrial components. By providing
customised services to analyse and understand your industrial processes
and operational technologies. We seek security flaws on all levels
starting from physical and network security to vendor-specific
vulnerabilities in ICS components such as supervisory control and data
acquisition (SCADA) systems, programmable logic controllers (PLCs) and
other industrial systems. Providing you with information on the
consequences of vulnerability exploitation and evaluating the
effectiveness of implemented security measures enables you to plan
further actions needed to fix flaws and improve security.
Our experts conduct internal penetration testing on agreed sets of
systems and components to identify all potential vulnerabilities in an
ICS environment. This testing includes:
Industrial control systems are designed with the assumption that they
would communicate via small, dedicated networks isolated from the public
internet and protected by the physical security of the plant itself.
However, the ubiquitous nature of Internet connectivity has radically
changed the threat landscape, as seen by the significant rise in
malicious activity within the Industrial Environment.
Arishti can deliver in-depth vulnerability assessment and penetration
testing services for industrial control systems, including testing live
production environments cautiously if required. Capable of handling
complex, large-scale OT networks in any ICS environment. We follow the
3-step process to assess the ICS security posture. First, we test the
ICS environment Network, then IT systems are tested, and finally, we
test selected ICS systems offline for vulnerabilities. Further, during
the penetration testing phase, we simulate tactics attackers use to
compromise ICS systems to find further vulnerabilities.
Our approach will help you and your organisation investigate and
identify security weaknesses. Assuring your board of directors,
customers, industry, or regulators that your systems have been tested
for cybersecurity weaknesses.
Regular security audits of your ICS, SCADA and OT networks are essential
for
defending your system against cyberattacks. Our security audit service
is
conducted based on accepted global industry standards such as IEC 62443
or
NIST 800-82 & others specific to the country or industry’s legal
requirements. In addition, we will adequately analyze the procedure for
applying updates, the effectiveness of anti-virus protection, usage of
any
counterfeit or 3rd-party software, firewall rules, and many other areas
of
your OT networks.
Arishti performs SCADA/ICS Risk and Vulnerability Assessments to provide
a
complete evaluation and holistic view of your organization’s security
posture to identify any possible flaw in large-scale OT networks. Our
skilled security assessor team conducts multi-disciplinary, multifaced
reviews of your company’s current OT ICS network and SCADA systems,
delving
deep into any industrial control system to identify vulnerabilities and
control gaps that an attacker could exploit. Our team will identify
threats
that could adversely affect critical operations and harm your OT
networks.
We document the risk assessment results and develop an action plan based
on
that. The action plan includes cost-effective solutions to mitigate
cyber
threats and risks. Also, it may consist of implementing new operation
procedures & policies and physical or technical control. As cyberattacks
continue to rise every day, it is essential to perform security
assessments
regularly.
It is becoming increasingly difficult to prevent security incidents. For
example, cyber-attacks targeting industrial organizations, including a
recent spike in ransomware, can potentially disrupt operations and pose
real
safety risks if not swiftly mitigated. While it may not always be
possible
to stop an attack before it infects your environment, it is possible to
limit the resultant damage and prevent the attack from spreading.
Our Incident Response (IR) Service helps organizations prepare for,
respond
to, and recover from cyber incidents in industrial environments. Our
experienced incident responders offer rapid response availability to
help
resolve the ongoing crisis as quickly as possible.
With the growing threat of cyberattacks, a SOC is vital to an
organization’s
ability to sustain operations, remain profitable, and comply with
applicable
regulations. The efficacies cybersecurity professional at Arishti can
help
design and deploy an effective SOC (Security Operation Center). We
intensely
focus on implementing the necessary & standard operating procedures to
ensure that the SOC is deployed with experts that can effectively deal
with
future threats and risks. Our SOC deployment is intended to comply with
all
regulations and deliver value to your business. We help choose the
technologically advanced platforms for the design and deployment of SOC
with
operational processes like incident management, case management,
escalations, roles, shift, etc.
