Securing Critical Infrastructure: Insights from Tom Sego

15 minutes

Tom Sego, founder and CEO of BlastWave, discussed his background in chemical engineering and his journey through various industries, including roles at Caterpillar, Eli Lilly, Emerson Electric, Alta Vista, and Apple. He explained that BlastWave was founded to combine Apple’s ease of use with cybersecurity, focusing on protecting critical infrastructure as it becomes increasingly digitized. Tom emphasized that human error is a significant security risk, citing an example from the San Jacinto Water District. This Follower Friday podcast is sponsored by UTSI International.

Tom’s podcast includes:

Critical infrastructure sectors (like oil and gas, transportation, and manufacturing) face higher cyber risks than traditional IT systems due to the severe consequences of attacks and the challenge of securing legacy devices.

Integrating old and new technologies is achieved by using a translation mechanism that enables secure communication between legacy systems and modern infrastructure.

Artificial intelligence (AI) has a dual impact: it can enhance attackers’ ability to automate cyberattacks, but it also offers opportunities to improve security, such as by eliminating vulnerabilities like passwords.

Technology solutions are essential for reducing the human burden in security, especially for defending against phishing and reconnaissance attacks.

Eliminating attack vectors (e.g., usernames and passwords) can significantly reduce security risks, regardless of how effective or frequent attacks become.

Focusing on the safety of critical infrastructure allows people to prioritize what matters most in life, such as family, relationships, and health.
