Most breaches do not come from sophisticated hackers — they come from missing basics. As a cybersecurity practitioner in Dhaka, these are the fundamentals I tell every business to implement first.
Enable multi-factor authentication (MFA)
MFA blocks the overwhelming majority of account-takeover attacks. Turn it on for email, admin panels and remote access today.
Patch everything, quickly
Unpatched software is the easiest way in. Automate updates for operating systems, browsers and plugins.
Back up — and test restores
Follow the 3-2-1 rule: three copies, two media, one offsite. A backup you have never restored is only a hope.
Train your people
Phishing is the number-one entry point. Short, regular awareness training dramatically lowers click rates.
Least privilege
Give users only the access they need. Fewer admin accounts means a smaller attack surface.
These five steps stop the majority of real-world attacks. Once they are in place, layer on EDR, monitoring and an incident-response plan.
