System for automatic evaluation of email messages
Frkal, Jan ; Červenka, Vladimír (referee) ; Koutný, Martin (advisor)
This diploma thesis deals with the design and realisation of system for automatic evaluation of e-mail messages. The system works with PHP language and MySQL database. It also allows automatic synchronisation. During the synchronisation e-mail messages are downloaded and saved using IMAP or POP3 protocol. Subsequently, the messages are analysed. During the analysis the reports are classified into types, according to pre-defined keywords. The system also works with black lists and white lists. If the sender of an e-mail is during the synchronisation found in the blacklist, that e-mail will be skipped. On the contrary, if the sender of an e-mail is found within the white list, that e-mail will be excluded from keyword matching and from the list is type and category loaded. Most of the values from the carried out evaluation of the e-mails can be clearly seen in advanced statistics. Pie charts and numerical statistics are available. Access to the system is protected by a login. Therefore, login can only registered users.

Webmail Traffic Reconstruction
Slivka, Miroslav ; Ryšavý, Ondřej (referee) ; Veselý, Vladimír (advisor)
Webmail applications are very popular these days. Besides typical usage, thanks to ciphered communication, they can be used for malicious activity like confidential data loss. This thesis discusses webmail events detection based on common webmail signatures in captured network traffic. Also there will be discussed SSL/TLS interception and decryption for further data analysis. The modules in this thesis are designed and implemented for Netfox.Framework forensics analysis tool. The Netfox project is developed at FIT BUT under security research project SEC6NET.

Horák, Michael ; Strašil, Ivo (referee) ; Pavelka, Ondřej (advisor)
The thesis deals with project lay-out and realization of the internet system dedicated to sending newsletters via e-mail. It especially aims at working with contacts and putting them in groups, editation of pre-prepared texts and sending the e-mails themselves. In the theoretical part, there’s described main traits of PHP language. There’s also described methods of creating the web forms, handing over their inputs and processing of that data. Next, there’s closer look on the PHP functions, especially for text processing, programming structures and conditions. Other functions, that can be found in this thesis described, are meant for sending the e-mails, creating hashs and managing sessions. In practical part, the problems are described generally. In the next part of a practical realization, this methods are looked closer upon and described more thoroughly. Also there’s defined how does the scripts work and which functions are used to make it work.
