The focus of this module is to provide a core understanding of the fundamental areas of cryptography, identity, and trust. A key feature is to cover both the theoretical areas, while often demonstrating practical applications including key protocols.
The module key areas are:
• Privacy, and Cryptography Fundamentals (Confidentiality, Sec Models, Cipher types)
• Asymmetric Key Encryption. Including RSA and Elliptic Curve Cryptography (ECC).
• Symmetric Key Encryption. Including AES and associated modes.
• Hashing and MAC Methods. Including MD5, SHA-1, SHA-256, SHA-3 and PBKDF2.
• Security Protocols: HTTPS, SSL/TLS, DNSSec, IPSec, WPA
• Key Exchange. Diffie-Hellman Method, ECDH.
• Trust Infrastructures. Digital Certificates, Signatures, Key Distribution Centres (Kerberos), OAuth
• Identity and Authentication (Passwords, Authentication tokens, Key pair identity, Multi-factor, Biometric Authentication).
• Distributed Systems: Blockchain, Distributed Ledgers and Cryptocurrency. Smart Contracts, Data Tokenization, and Transactions.
• Future Cryptography: Zero Knowledge Proof, Homomorphic Encryption, Light-weight cryptography, and Quantum robust methods.
• Host and Domains: Trust systems. Authentication with Active Directory Authorisation: Log integration and rights.
This module will cover a range of elements concerned with digital penetration testing and security testing. Initial lectures consider important soft skills such as documentation techniques, reporting, the law, and risk assessment and management. The practical skills and their related theoretical knowledge include operating system weaknesses, information gathering (both passive and active), and various ethical hacking techniques and processes. Considerable practical focus is made on available tools to assist in auditing and penetration testing. Aspects targeted include operating systems, common network services, and network-based applications.
This module will cover elements of operating system disk-level architectures, such as Windows and Linux. This will allow students to study how operating systems store system and user data, and thus students will gain an understanding as to what information could technically be held on such systems. This data could include user files, as well as user activities such as login session data, browsing histories, operating system manipulation, and general user interactions with a variety of operating system tools. This understanding will be expanded through theoretical knowledge and practical exercises in extracting information from systems, using a variety of open source and commercial forensic analysis tools, and documenting the results of such a process using consistent and thorough evidential procedures. This includes the production of event timelines, as well as the analysis of system logs, operating system state, file systems, and application data. The module will also consider the ethical and professional issues related to digital forensics.
The aim of the module is to develop a deep understanding of advanced areas related to security and live/network forensics, with a strong focus on virtualised environments that will allow graduates to act professionally within incident response and in malware/threat analysis. An outline of the main areas includes:
• Threat Timelining This involves networks and host traces around key threats, such as DDoS, malware infection and data loss.
• Host Investigation Evidence Gathering: Windows, Linux, Android and Mac OS.
• System Architectures, Services and Devices. Networked infrastructures (Servers/Firewall/IDS/ Syslog).
• Network Protocol Analysis. Advanced Network Protocol Analysis, Advanced Trace Analysis, IDS Signature Detection, and Security Threat Network Traces.
• Log Capture/Analysis, and Time-lining. Creating large-scale data infrastructure and analysis methods such as Big Data, SIEM and cross-log analysis .
• Malware Forensics. Code Analysis, Host/Network Analysis, Reverse Engineering. Mobile/x86 architecture, Machine Code Analysis, Vulnerability Analysis and Sandboxed Analysis.
• Malware Analysis. Encoding methods. Static/Dynamic Analysis. Disassembly. Obfuscation. Behaviour Analysis. Encoding methods.
• Advanced Malware Analysis. Anti-disassembly, anti-debugging, packers and unpackers, malware launching, malware signatures, and shell code analysis.
• Data Hiding Data hiding methods, tunnelling, and disk encryption.
• Current Related Research.
