Simplifying Cybersecurity: Back to the Fundamentals - ThreatLocker
Overview
In this masterclass from the CISO Inspired Summit Ireland at Carton House, Seamus Lennon, VP of Operations at zero trust endpoint security provider ThreatLocker, argues that as threats grow more complex and the stakes get higher, going back to the fundamentals has never been more important.
Drawing on more than 25 years in IT, Seamus traces how attacks have evolved from nuisance viruses to organised crime, and walks through simple, effective controls that make a real difference in real-world environments.
Key takeaways
- Zero trust at the endpoint, including application allowlisting, has been around for years and no longer needs to be a headache to manage.
- Security frameworks are often vague, so translate them into simple, practical controls your teams can actually apply.
- Basic hygiene matters: an unlocked screen left unattended for 26 minutes is an open door.
- Attackers who reach hypervisors can shut down virtual machines, strip security software and encrypt unprotected disks, while in-memory tools can evade EDR.
- Block what you don't need, such as SMB on workstations and USB storage, and ring-fence tools like PowerShell so they can't access or exfiltrate data.
