Building SQL firewall: insights from developers
How SQL firewalls can help to protect databases from SQL injections: the main difference from web application firewalls (WAFs), common usage scenarios, pros, and cons. We implemented SQL firewall as part of data encryption proxy Acra, and we will share insights about security and development decisions. Expect a story about parsing SQL protocols, matching rules, hidden dangers of logging, best of configuration and usage patterns.
