Albert Pichlmaier, Senior Cybersecurity Engineer, Drew & Napier LLC


Albert is currently working at Drew & Napier LLC as Senior Cybersecurity Engineer, where he supports the TMT and Data Protection Practice Groups in their legal work. In addition, he is also the Course Director for the Cybersecurity Modules at Drew Data Protection & Cybersecurity Academy.

Before, he was an Executive Manager with the Personal Data Protection Commission (PDPC), where he was involved in technology assessments for data breach investigations, research into trending/disruptive technologies, and was advising on technical aspects of various PDPC guidelines and publications (amongst other matters). Prior to his role with the PDPC, Albert worked in a number of technology-related roles with IDA and various companies in Germany, Spain and Singapore including as VP of research and development, lead Testware developer, and soft/firmware engineer. He was also a technopreneur, having set up a company to provide testing tools for embedded systems and smartcard applications.

Albert holds a degree in Computer Science from Germany. He is a Certified Information Systems Security Professional (CISSP), a Certified Data Privacy Solutions Engineer (CDPSE), and a Certified Blockchain Developer. He has a strong interest in a variety of topics like Artificial Intelligence/Machine Learning, Data Analytics, Big Data and Data Visualisation, and Quantum Computing.


In this session we will look at some high level anchor points in terms of Blockchain and Personal Data, which need to be well-thought-out when considering use of such technology in the context of a specific regulation. There is no simple answer, whether ‘matching them up’ would lead to a ‘happy ever after’ or a more shaky, troubled symbiosis. The points discussed, therefore, are more about aspects one might want to include in a risk management consideration (e.g. as part of a DPIA [Data Protection Impact Assessment]) than any kind of easy to follow recipe (or marketing hype talk).

Bernard Tan, Director/Cybersecurity Group, GOVTECH


Bernard is a Director in GovTech leading the GovTech Cybersecurity consultancy team to provide risk based consultancy services to architect the cybersecurity of Nationwide and Governmentwide strategic projects. Through his 15 years in the public sector, he has undertaken various cybersecurity roles and projects in areas of Homeland security. He held key roles such as Ministry Chief Information Security Officer (MCISO) and Head of Information security in MHA.

In his role as MCISO, he was also appointed as security advisor in audit and risk committee to provide security guidance to the home team's audit steering committee. Prior to joining GovTech, he was a security product developer and solution architect.


The current state of meeting compliance requirements subscribes a “good enough” security principle. This state of mind stands to be challenged with the rapid change in business needs such as the COVID-influenced working new norms that stretch the security compliance boundaries. The threat landscape has also continued to evolve and reminds us about the “cyber chase”, where our trust boundaries have to be redefined in the realms of people, processes and technology domains.

“Where we are now” will need a rethink and we should move towards a “where we should be” state. In this presentation, I will share some of the key sensible cybersecurity principles that help us not only maintain our compliance posture, but also inject agility which acts as tailwind to move us ahead with a pragmatic and sustainable cybersecurity undertaking.

Daniel Ehrenreich, Consultant and Workshop Lecturer, SCCE SCADA Cyber Security (Israel)


Daniel Ehrenreich, BSc. is a consultant and lecturer acting at Secure Communications and Control Experts, periodically lecturing at industry conferences cyber defense for industrial control systems; Daniel has over 30 years’ experience with ICS systems for: electricity, water, gas and power plants as part of his activities at Tadiran, Motorola, Siemens and Waterfall Security. Reselected 6th time as the Chairman for ICS Cybersec 2021  taking place on 27-10-2021 in Israel


CS-OT Security – Industrial Control Systems (ICS), also known as Operation Technology (OT), are broadly used in a wide range of industrial and utility applications. These ICS-OT systems include an Automation Server (AS) integrated with the Human Machine Interface (HMI) and use serial, ethernet or wireless media for connecting with Programable Logic Controllers (PLC) and a broad range of sensors and actuators.


While the majority of ICS-OT systems can be structured according to the Purdue Model (Layer 0 – sensors and actuators, Layer 1 – PLCs/RTUs and Layer 2 – the AS and the HMI), the architecture and cyber security solution for each ICS-OT must be defined and designed according to the criticality of the control process. In some cases, the cyber security requirements may be lighter and in other projects for a similar application the specification can be tougher and more complex. The ICS-OT expansion with Industrial Internet of Things (IIoT) ecosystems enhances the business performance and the productivity, but also increases the cyber-attack surface and the risk of attack against the organization. The system architect will have to deal with factors such as operation safety, reliability, productivity, data confidentiality, data integrity, operation convenience and lastly, but most importantly, with cyber security. This presentation will clearly elaborate on the risks and the consequences caused by a cyber-attack.

Users are connecting to applications and data residing on premises and in the cloud from any location and device today. With accelerated adoption of multicloud solutions and a distributed workforce, organizations are struggling to protect against evolving cyber threats, ensuring they have end-to-end visibility across their architecture and isolating and resolving performance issues across the internet, cloud and SaaS. Addressing this new multicloud, distributed work environment requires a new approach to networking, security and monitoring. This is when Secure Access Service Edge (SASE) which combines networking and security functions in the cloud comes into play, to deliver secure access to applications and users, regardless of where and when they are connecting from. Kerry will share how SASE can help organizations consolidate various functions which were traditionally delivered in silos, and how businesses can start on their SASE journey.

We hear about new breaches happening to organisations despite their enormous cybersecurity spends: databases are leaked online for sale; systems are locked down by ransomware; patents and confidential information are stolen; and operations are disrupted.

What could be the issue?

In this session, we share our insights and observations surrounding the common “mistakes” organisations might make when it comes to planning, budgeting and executing security exercises, either done incorrectly or inadequately, which could be “a waste of money”.

We will also introduce an innovative approach to attack simulations including a cyber resilience programme that will help organisations to improve their cyber defence in the long run.

Using and storing private data is a necessary part of doing business for most organizations and it remains both a highly targeted asset by attackers, as well as, a highly governed asset for regulators.  For years, organizations have tried to meet demands around data with limited successes and numerous failures.  In this presentation we will explore the modern demands on data from pro-active security, post-breach incident response, industry regulatory requirements to the more recent consumer privacy requirements, all while highlighting the questions organizational functions should be asking to determine how effective their program may be.
