Optimal Source-Based Filtering of Malicious Traffic ABSTRACT: In this paper, we consider the problem of blocking malicious traffic on the Internet via source-based filtering. In particular, we consider filtering via access control lists (ACLs): These are already available at the routers today, but are a scarce resource because they are stored in the expensive ternary […]

Revisiting Defenses against Large-Scale Online Password Guessing Attacks ABSTRACT: Brute force and dictionary attacks on password-only remote login services are now widespread and ever increasing. Enabling convenient login for legitimate users while preventing such attacks is a difficult problem. Automated Turing Tests (ATTs) continue to be an effective, easy-to-deploy approach to identify automated malicious login […]
