Web application attacks are an increasingly important area in information security and digital forensics. It has been observed that attackers are developing the capability to bypass security controls and launch a large number of sophisticated attacks. Several attempts have been made to address these attacks using a wide range of technology and one of the greatest challenges is responding to new and unknown attacks in an effective way. This study aims to investigate the techniques and solutions used to detect attacks, such as firewalls, intrusion detection systems, honeypots and forensic techniques. Data mining and machine learning techniques, which attempt to address traditional technology shortcomings and produce more effective solutions, are also investigated. It was aimed to contribute to this growing area of research by exploring more intelligent and convenient techniques for web application attack detection by focusing on the data mining techniques in forensics.

In speech processing, identification of speaker's gender has been considered as a topic of interest by many studies so far. Although various methods and approaches have been proposed to detect gender of a speaker, Voice Onset Time (VOT) values of stop consonants of a language can also contain cues about the speaker's gender. In this study, VOT values of six stop consonants (/p/, /b/, /t/, /d/, /k/, /g/) in Turkish language have been analyzed to find gender evidences by using classification algorithms like SVM, KNN, Logistic Regression etc. 10 males and 10 females speakers have uttered 48 isolated meaningful (number of combinations of all stop consonants and all vowels) Turkish syllables in this work. As a result of this study, VOT values of unvoiced stop consonants (/p/, /t/, /k/) together as one parameter have been found to be gender-related with a success rate of 90% via Ensemble algorithm. Also, stop consonant /t/ has been marked as most gender-related cue in a syllable, on the other hand /b/ has been detected as the least gender-related stop. These findings proved that acoustic VOT parameters of Turkish stop consonants, especially unvoiced stops, can be seen as gender distinctive feature for Turkish speakers.

Sound montage is used not only for the music and film industry, but also for criminal cases. The goal is sometimes to hide the crime and sometimes to blame the innocent. The montage always leaves some marks behind. In this study, the methods used to detect these traces are summarized and it is debated whether these traces can be completely erased. Since the sound signals can be considered periodically, they can be expressed by the Fourier series. Since the continuity of the cutting process will be deteriorated, a Gibss effect occurs and can be detected in a visual analysis. Background noise and acoustics are also used to detect the mounting in auditory analysis. The detection success rate is close to 100%. But sometimes the expert's fatigue, inexperience or carelessness and some montage tracks may not be detected.

The digital world is continuously changing, and new technologies affecting every aspect of our life. In order to keep up with these changes and have some impact and/or control over it; we must conduct advanced research on information technologies, future networks and security. In addition, we must educate the necessary human resource for the field. Today, developed countries are establishing large-scale research and education testbeds to support their researchers. Using these testbeds, they seek to increase their impact in the technology and security fields. In this paper, we propose a national information and communication technologies and security testbed, TRCyberLab. We also propose a road-map for the establishment and sustainment of this testbed. We believe, this testbed will help researchers in Turkey to conduct advanced research and develop new technologies also have an impact in the field.

The steganography word is derived from the combination of the steganos (στεγανός), which means “covered, hidden or protected”, and the graphein (γράφειν), which means “writing”. The main purpose of steganography studies is to prevent the hidden data from being to obtained by unauthorized persons. In order to realize the basic purpose of the steganography methods, there should be minimal change in the pattern file. In this study, LSB method which is one of the methods of concealing digital image information is examined. In this study, a new method of data hiding is proposed in order to minimize the changes occurring in the cover file while hiding the data with LSB method and to create the most appropriate mask to make it difficult to obtain hidden data.
