Hello David,
As mentioned by Morgan, there are plenty of papers and blogs about corruption and countering-corruption on the ISSAT website. As you specifically referred to the security sector, may I draw your attention to an event last month sponsored by SIPRI, where they hosted a lecture by Mark Pyman, Director of Transparency International's Defence and Security Programme. The lecture was entitled
Transparency in the military sector: the role of parliaments and would be definitely worth listening to.
I would add, however, a couple of words of caution on the discussion. First, as SSR practitioners we really need to be holistic in our worldview of corruption and not just focus on the security sector otherwise we might be missing systemic corruption across the board. Second, I would totally agree with you that corruption is not just about bribery. Corrupt politics in a country can easily create a climate of impunity that goes well beyond the opportunity costs of lost government revenue in security and defence budgets. This a point that James Cohen alludes to in his OpenSecurity blog. I believe therefore that ISSAT might even wish to look again at the definition of corruption that they have on their SSR Glossary. And finally, we always need to take into account the context, and particularly local culture, in our SSR interventions. As a former NATO Senior Civilian Representative in Afghanistan said: "My obligation is your patronage is his corruption."
Happy to talk further.
