What are the Programming Languages Required for Cybersecurity?

Technology continues to play an essential role in daily life processes causing the world to be connected extensively. Whether it is video calling loved ones living on the other side of the world or using an AI assistant to control critical operations, technology has become mainstream, and it is here to stay. It is indeed a blessing to many, including cybercriminals, who are increasing by the day as new, easy to use, but highly sophisticated malware variants emerge. Cyber actors hone their skills to compromise protected networks and systems belonging to an individual or a company. Cyber-attacks have increased tremendously recently, thus requiring industry leaders to not only concentrate on innovating new technological advancements but also to eliminate and mitigate adverse cyber events.

To mention just a few cybersecurity statistics, Gartner estimates that the global spending on cybersecurity will surpass $3.9 trillion by the end of 2020. Also, a study by Accenture showed that 68% of the sampled business leaders believe that cybersecurity threats and risks are on the rise. Moreover, the global number of machine and human passwords will reach 300 billion by 2020. It is also worth noting a research finding by the University of Maryland, which revealed in every 39 seconds, cyber adversaries attempt an attack, with hacktivist attempts averaging 2,244 times daily. As of 2019, the average cost of a cybersecurity attack or a data breach was $3.92 million.

These and many other statistics are proof that cybercriminals are relentless in delivering sophisticated malware. They focus on breaching critical systems to exfiltrate data, spy on users, or achieve other illegal purposes.

Although a shortage of cybersecurity skills and talent has contributed to the rising cases of cybercrime, developing insecure applications and systems is also to blame. In essence, DevSecOps is a prerequisite for developing secure and resilient applications. The concept means development, security, and operations, and it involves observing the recommended practices to ensure a secure development environment to provide end-users with trusted and safe products. Cyber actors can, however, still work around and compromise systems with the highest security levels.

To prevent this, cybersecurity professionals need to possess diverse skills to be able to detect security issues in a system and deploy sufficient mitigations. For this reason, having a strong programming background can equip the required skills needed to thrive in the cybersecurity profession today.

Importance of Programming to Cybersecurity

Henrique, a Brazil-based Python expert and trainer, stresses that “besides keeping abreast with the latest happenings in the cybersecurity field, you also need to be acquainted with various programming languages.”
