Profile bio

About Mark O'Brien

I am always looking for an opportunity to integrate a secure way of thinking into your operations.I am an information technologist with over 20 years of service-delivery experience. I believe that information security and assurance is not a bolt-on feature to business, but instead is a small shift in thinking about how data the business relies on is managed. This includes being a salesman, preacher, counselor, teacher, and mentor; all of these areas I have been successful in while helping the business manage their information. My expertise and passion is in information security and information assurance. The marriage of policy, technology, methods and intent into the current operations is how I express that passion. I am experienced in teaching and training IT topics to a variety of audiences. I am very familiar with methodologies such as ITIL, and familiar with compliance such as PCI and FISMA. I build and maintain strong interpersonal relationships. I have experience in project coordination and management, requirements drafting, and contractor and vendor selection.A little history. I compromised my first network in 1988, though that was hardly 1337 skills. In 1996 I was tasked with securing computers as it was found out that I knew how to break them. I continued breaking computers for a few more years but since I have been more focused on playing the harder role of protecting them.

Listed skills include Cissp, Security Clearance, Security+, Information Assurance, and 46 others.
