"PHP Web Security Monitor" is designed to protect Internet sites created with PHP from malicious queries from hackers and Web viruses. It filters common PHP variables via prepared security patterns and compares (unprotected) input variables against patterns of dangerous data, such as SQL injection, XSS injection, and PHP code compromising.
dynalogin is a distributed two-factor authentication suite that combines a secure UNIX server and API with an Android soft token. Open standards (HOTP, TOTP, and soon OCRA) are used for one-time passwords. A C library is provided for inclusion in existing software and Web sites. OpenID (using SimpleID) is supported for Web applications and single sign on. PAM is supported for easy UNIX and LDAP integration (SASL, RADIUS, and JAAS in development). It works with Google Authenticator or the dynalogin Android application.
