Android 4.4.4 "KitKat" hardened binary distribution
This is the Android 4.4.4 "KitKat" hardened binary distribution by Guido Trentalancia for
the Sony Xperia E3 device (D2203, D2206, D2243, D2202):
This Android distribution is mostly focused on security and privacy and it is provided freely to you, in the hope that amongst other things it will prevent tedious and dangerous electronic "infections"
: if you like it and benefit from using it, I would recommend making a small donation to: International AIDS Vaccine Initiative
. For those of you opposing the use of vaccines, I would still recommend to read the following resource carefully: Clearinghouse on Male Circumcision
This distribution includes over a thousand fixes to common security vulnerabilities that would otherwise let potential attackers execute malicious and harmful code remotely to obtain sensitive information from the device or, even worse, take complete control of the device.
In addition, the following security features and improvements, not available in the original distribution from the device manufacturer, are included in this hardened distribution:
- Security Enhanced Linux (SELinux) enabled (Enforcing Mode) rather than disabled (Permissive Mode) and using a customized policy;
- Updated Certificate Authority (CA) certificates bundle;
- End-to-end encryption for the Web (HTTPS) and other Internet services such as Mail Transport (IMAP/SMTP) using Transport Layer Security (TLS) only, thus disabling the insecure Secure Sockets Layer (SSL) protocol;
- Removal of several obsolete, insecure and weak ciphers previously used for encryption using TLS and other protocols;
- Optional browser protection from the CORS Vulnerability;
- New browser option to disable Third-Party Cookies for increased privacy;
- Removal of several other online tracking and identification mechanisms (super cookies) such as TLS Session Tickets and TLS Session Resumption, TLS Channel ID, Shared Dictionary Compression over HTTP (SDCH) information persistance;
- Stronger GCC stack-smashing protection.
An extensive collection of free applications from various authors is also available: selected binary Android applications
The following optional extensions are currently available upon request: SMS (Short Message Service) Encryption. Further extensions, functionality or security enhancements and customizations can be developed upon request.
