Predictive blacklisting with DShield

The DShield project is hoping to change how we protect our networks from malware with predictive blacklisting. Using a method similar to Google’s PageRank, DShield collects logs from network administrators to help develop a score based on maliciousness. They combine this score with information about where the malware has already hit to determine an overall threat level.

Similar to antivirus programs, the system still relies on networks being attacked to rate the threat level. They have shown though, that the predictive method is consistently more effective than manual blacklisting. The system has been available for free for the past year. Those utilizing the system have been reporting positive results. They do note that there are a few people whose network infrastructure doesn’t match up with the predictions very well.
