I host and maintain several websites. The users pay to have their sites maintained and secured. However, with the amount of web applications like joolma, wordpress, ect... and their plugins, I need a way to monitor and stay on top of exploits and fixes as they come out.
Now one idea is to follow twitter and stream the alerts on a screen. Are there other ideas? I don't believe every place as a mailing list that alerts you of security issues.
EDIT: Also started to watch Twitter feeds but they seem very limited.
