Defence Industry Security Program (DISP). Previously, companies and contract staff had to have a Defence contract to get a security clearance, but it was difficult to get a contract without a clearance. The new procedures allow a company to apply for DISP membership, and then tender for contracts. The company can then appoint their own Security Officer, to nominate staff for security clearances. That all makes sense, but one curious side effect is that companies will also have to check the qualifications of staff. This may require universities to improve the certification service they provide. An easily faked paper certificate will likely not be sufficient.
As well as private companies, universities can apply for DISP membership. There are four levels of membership (Entry, 1, 2, 3) and four categories (Governance, Personal Security, Physical Security, Information & Cyber Security), making a sixteen cell matrix.
