New York, New York, United Statescomputer & network security

1GCYBER researches cybersecurity skills in developing countries. Researchers recently published work that explored Latin America and the Caribbean. Key findings include improving support for cybersecurity education, establishing coordination and collaboration between the public and private sectors, improving information-sharing structures, and creating an inventory of critical infrastructure assets at a national level. Our new framework addresses these concerns by examining national cybersecurity strategy, the current state of the cyber workforce (skill set), cybersecurity challenges, and the current impact of cybercrime on economic sectors. Governments and stakeholders in developing countries can benefit from this framework because of its external and internal validity. Cybersecurity is a driver of economic growth and organizations must take full advantage of it. A strategy for differentiation must include workforce skills development. Although it is challenging to measure cybersecurity competency across the organization, employee knowledge and skills are inputs to cybersecurity governance. We are intrinsically motivated to explore and investigate the challenges of developing cybersecurity and governance programs. The governance frameworks provide guidance, but organizations require professionals. Let us analyze the gaps in your governance program to develop tailored cybersecurity roadmaps intrinsically.

That is, we build comprehensive, realistic, effective IT security solutions that solve our clients' problems. • We are solutions builders who provide comprehensive, complete IT security management programs. In an IT security solutions initiative involving many vendors, we are the project managers who pull it all together and make sure it works as planned – for the long term. • Adsero's ideal clients are medium to large businesses whose executive teams are serious about developing relationships with IT security experts who can identify, build and manage long-term solutions supported by written policies. • An IT security audit merely observes the status of your environment, and always requires follow-up to address the deficiencies the audit identified. Most firms don't have the staff to effectively execute implementation and develop written policies to continually safeguard their businesses. • The audit is one step in the process. Once the risks identified have been addressed, IT security policy written, risk management standards set and people trained, you can feel confident that probability of a breach has been significantly lessened. • With a combined 45 years in IT security, Adsero's principals have seen it all.
