On May 19, 1998 seven intrepid hackers from Boston drove a Ford Econoline van down Route 95 to Washington DC to offer testimony to the Senate Government Affairs committee on the state of computer security in government. Their voices still echo across the Internet today.

In an article I just released, I discuss how you can build your own compliance smorgasbord from ISO/IEC 27002 and NIST CSF, picking the controls that suit your business and your risks. morrisec.com.au/nist-cyberse… #compliance #riskmanagement #iso27001

You may have noticed two little robots associated with Morrisec, Morri and Dr Bot. We have had great feedback on both these robots, but people then ask, why robots? So, I have written an article to provide some context. morrisec.com.au/who-are-morr… #cybersecurity #securityawareness

Doing a lot of ISO/IEC 27001 work at the moment and getting a lot of questions, and there's also a lot of misconceptions. So I've put an article up on the @morrisec_au site addressing these questions and issues. morrisec.com.au/what-is-iso-… #infosec #compliance #riskmanagement
