Digital forensic science involves the detection of digital fraud with malicious intent. The scope of digital forensics can vary from simple information retrieval to reconstruction of a series of events.
The capabilities of contemporary software have made the manipulation of digital content more complex and harder to detect.Although it’s often hard to quantify, the Digital Forensics Association estimates losses related to digital fraud to be more than $630 million dollars.
Tools are available to detect and reduce your organizations risk.
The Marjau Systems team provides you with an authority experienced in many aspects of digital forensics including:
- Cryptography
- Steganography
- Intrusion Detection
- Biometric Technology
- Forensic Data Profiling
Cryptography
Cryptography can be defined as the practice and study of writing in secret code to hide information. Cryptography is necessary when communicating over any untrusted medium, which includes just about any network, particularly the Internet.
Since the advent of the computer, the methods used to carry out cryptology have become increasingly complex and its application more widespread. Modern cryptography crosses the disciplines of mathematics, computer science and engineering.
Steganography
Whereas the goal of cryptography is to make data unreadable by a third party, the goal of steganography is to hide the data from a third party. Forms of steganography often are used in conjunction with cryptography so that the information is doubly hidden.
Steganography includes the concealment of information within computer files. In digital steganography, electronic communications may include steganographic coding inside of a transport layer, such as a document file, image file, program or protocol.
Detecting and defeating both cryptography and steganography has become an important part of protecting our country against those who may want to harm us. Employing a resource with significant experience in these methods of digital forensics will ensure your task is handled properly.
Intrusion Detection
An Intrusion Detection System is a device or software application that monitors network and/or system activity for malicious intent. Intrusion prevention is the process of performing intrusion detection and attempting to stop detected incidents.Intrusion detection and prevention systems are primarily focused on identifying possible incidents, logging information about them, attempting to stop them, and reporting them to security administrators.
In addition, organizations use intrusion detection systems for other purposes, such as identifying problems with security policies, documenting threats and deterring individuals from committing violations. Intrusion detection systems have become a necessary addition to the security infrastructure of nearly every organization.
The team at Marjau Systems has deep experience with both Host-Based and Network-Based forms of pre-emptive real-time intrusion detection.
Biometric Technology
Biometrics comprises methods for uniquely recognizing humans based upon one or more intrinsic physical or behavioral traits. In computer science, biometric technology is used as a form of access control. Biometrics can also be used to identify individuals in groups that are under surveillance.
A biometric security system operates in both verification and identification modes. Verification occurs when a stored biometric scans is compared to a real-time scan. Identification occurs when a real-time scan is used to identify an unknown individual. The identification mode is often used as a surveillance tool to identify a potential threat individual.
Biometrics has emerged as a promising technology for authentification and has already found a place in most hi-tech security areas.
Various forms of biometric technology are being utilized in healthcare and military applications. Applications of biometrics to enhance security are predicted to expand at unprecedented levels. Although our biometric capabilities are vast our skills in this science began with the discipline of liveliness authentification.
Forensic Data Profiling
Forensic data profiling refers to the study of multiple complex data sources in order to develop a forensic profile identifying dynamic security threats and suspect activities. This information links investigation, intelligence, surveillance and risk analysis entities.
Forensic data profiling is conducted using advanced data mining techniques to identify relevant patterns within a large quantities of data. Modern methods incorporate digital evidence, internet activity and software access.
Enterprise organizations are challenged because data is entering the enterprise from multiple diverse sources. It’s imperative that you work with a firm that has experience analyzing all modern data sources.
