Mark Low, CSIT Undergraduate Scholar, is constantly staying abreast of the latest Linux security and system developments while adapting to the evolving cybersecurity landscape. As a Linux Security Engineer at the Centre for Strategic Infocomm Technologies (CSIT), he conducts exploratory analysis of threats on Linux systems, as well as designs, develops, and implements innovative software solutions on the Linux platform to counter threats.

We speak to Mark to learn about his dynamic work and what he enjoys about it.

What sparked your decision to pursue a career in security engineering?

I would credit my relative, a lecturer at Nanyang Polytechnic, who introduced me to the dynamic world of cybersecurity and its abundant opportunities. This inspired me to pursue a career in security engineering as I wanted to do something challenging and meaningful at the same time.

Why did you choose the CSIT Scholarship?

In polytechnic, I took up the CSIT Diploma Scholarship. During the internship with CSIT, I gained invaluable exposure to the exciting world of cybersecurity and really enjoyed myself. The experience convinced me to apply for the CSIT Undergraduate Scholarship to continue my journey with CSIT.

The scholarship provided invaluable financial assistance, mentorship, additional learning opportunities, and assurance of a meaningful career. This significantly eased my undergraduate journey and allowed me to focus on my studies.

How has the scholarship aided you in your career?

My academic background in Information Security has equipped me with the knowledge and problem-solving skills to effectively contribute as a Linux Systems and Security Engineer. For example, the red teaming techniques and methodologies I learned during my studies prepared me for CSIT’s in-house training and my subsequent role as a blue teamer.

Walk us through the daily job scope as a Linux Security Engineer

The cybersecurity landscape is fast-paced and threat actors are becoming increasingly sophisticated. To stay ahead, we develop advanced detection tools and research the latest techniques and procedures of sophisticated threat actors to create countermeasures against them.

CSIT also places a high emphasis on training and learning. To stay ahead, we are sent on many local and overseas courses to further hone our skills. This continuous development ensures that we remain up to date with the evolving cybersecurity landscape.

My role involves building and securing Linux servers and systems against potential cyber-attacks. Our blue teaming efforts include developing security software to detect potential intrusions and writing scripts to detect server misconfigurations.

Could you name one work-related challenge that further cemented your joy in your current role?

One challenge I faced was encountering technical roadblocks while researching new ideas to improve efficiency and effectiveness. To overcome this, I revisited the fundamentals, explored alternative methods, and discussed their feasibility with the senior engineers.

I am thankful to have wonderful teammates who are very patient in addressing our queries and providing great advice on developing solutions to challenges. With their guidance, I was able to achieve the desired outcomes for my work.

The technical depth of my work makes it very challenging, but it is also most rewarding and fulfilling when I manage to develop solutions to the challenges faced. I am also glad that CSIT offers many cybersecurity research opportunities, allowing me to engage in new projects and further develop my expertise.

That’s great! Tell us about your career milestones and what you hope to achieve in the future

My most significant professional accomplishment so far is achieving a desired outcome for a cybersecurity research project and collaborating with my counterparts to build and deploy the project on our servers.

I hope to better contribute to CSIT by taking up higher appointments to lead and guide fellow engineers. To achieve my goal, I will continuously upskill myself to gain the necessary expertise and leadership skills.

CSIT provides leadership development opportunities and encourages cross-postings including to corporate roles. This facilitates holistic development and better prepares us to take on leadership roles.

What would you say to our readers who are considering a similar career trajectory?

As technology is always evolving with new cyber threats emerging frequently, continuous learning and upskilling are essential to stay ahead.

At CSIT, we work with advanced technologies and grow alongside some of the best cybersecurity experts in Singapore. If you are keen to pursue a cybersecurity career that is challenging and immensely meaningful, I strongly encourage you to apply for the CSIT Undergraduate Scholarship and make a meaningful impact in protecting Singapore’s security.
