55 Security Assessment of Microsoft DirectAccess #55 Source:

56 Conclusion DirectAccess is a relatively new technology that offers the corpnet users a flexible, an always-on and an automatic access to the internal resources. The security assessment process showed that IP-HTTPS is a very critical component, which could be utilized by attackers to perform many IPv6 attacks on both DirectAccess client and server. The Thesis also pointed out the necessity of reviewing the configuration of both TLS and IPSEC protocol. The infrastructure tunnel and the 6to4 tunneling represent very attractive sources of attacks Security Assessment of Microsoft DirectAccess #56
