Accelerating Cybersecurity Culture Maturity in the Workplace

A Digital, Data-Driven Organization

While companies can have an excellent safety culture, cyber threats are always on the horizon. Trends in ICS cybersecurity have reported more unauthorized attempts and a marked increase in malicious code attacks. As a commercial off-the-shelf (COTS) software, ICS uses more and more hardware and software with IT technology being embedded (e.g., Windows operating system, ethernet IP-based communication, and virtualization such as VMWare and Hypervisor).

Slide1

Implementing IP exposes ICS to the same vulnerabilities as IT. Common cyber incidences include blue screens, denial of service (DOS), and unauthorized remote access. Studies have shown that about 24% of cybersecurity threats come from insiders who inadvertently compromise businesses. Unknowingly, one can plug in an infected USB stick into a PCS computer and spread malware into plants, causing sometimes irreversible damage.

Therefore, aggressive education, training, visual management, audits, and the courage to give feedback to staff on PCS cybersecurity malpractices is surely needed. As part of an accelerated cybersecurity culture at the workplace, one must engage staff, conduct awareness training, and foster an understanding that becoming inactive and uneducated on cybersecurity risk management can lead to a major loss of business.

PETRONAS Use Case

For example, in the case of a threat from a phishing email, which accounts for more than 90% of cyberattacks, we at PETRONAS heavily engage our staff on human firewall campaigns. This includes not including confidential information in an email subject, logging out at the end of computer sessions, and periodically changing passwords. With a strong staff conviction, we further accelerate a matured cybersecurity culture at the workplace.

The followings images are exhibits of visual management, cybersecurity collaterals (OT stickers, PCS rules posters and cards) that are issued to all our sites at PETRONAS:

OT/IT Convergence

In leading the OT Cybersecurity team at PETRONAS, we engage and support staff as much as possible. We build and nurture our best performing teams with our new cybersecurity taskforce, as well as guide them using international standards best practices on sustainable, pragmatic approaches. The taskforce’s leadership ensures PETRONAS’ growth and sustainability, no matter what obstacles may come during the crafting and shaping of new outfits within the cybersecurity team.

Slide2

With IT/OT convergence, which requires cybersecurity to be looked at from a single enterprise lens, both our IT and OT staff are brought into the same classroom to share and learn from each other. During our classroom trainings on fundamental cybersecurity for ICS and IACS, for example, both IT and OT terminologies and priorities (such as confidentiality, integrity, and availability) are taught so that both teams can achieve commonality with our company KPIs. It is indeed a convergence in action when a nurtured trust is sowed for both departments which were previously siloed. Indeed, managing cybersecurity risks requires not only teamwork, but both alignment between processes and technology.
