Advanced Persistent Threats
… kyberuhkiin, jotka tunnetaan nimellä Advanced Persistent Threats (APT). Opinnäytetyön tarkoitus on antaa selvitys siitä, mitä APT:t oikeastaan ovat ja mitä kaikkea erityisen edistyneisiin kyberuhkiin liittyy. Tutkimme keskeisiä työkaluja ja metodeja, joita hyökkääjät käyttävät. …

Securing information systems against advanced persistent threats (APTs).
Advanced Persistent Threats (APTs) have been a major challenge in securing both Information Technology (IT) and Operational Technology (OT) systems. APTs are sophisticated attacks that masquerade their actions to navigate around defenses, breach networks, often over multiple network hosts, and …

Using detection in depth to counter SCADA-specific advanced persistent threats
… environments. Moreover, the recent advent of advanced persistent threats (APTs) has highlighted the relative ineffectiveness of existing SCADA-centric security solutions. In this thesis I will identify various algorithmic strategies for detecting and mitigating common APT attack vectors …

Quantifying the Impact of Defensive Cybersecurity Effort Against Advanced Persistent Threats For Industrial Control Systems
… defense tactics for countering cybersecurity threats within Industrial Control Systems (ICS) by modeling the offensive and defense interactions between ICS organizations and Advanced Persistent Threats (APTs). In recognizing the persistent and targeted nature of APTs, this research underscores …

Dominion: A Game of Information Exploitation
… for managing security resources in response to Advanced Persistent Threats. In this thesis, we place FlipIt within a more general category of 'stealthy move' games, and provide an approach towards solving such games. We produce a new stealthy move game, 'Dominion', and derive Nash equilibria for …

Threat Detection in Program Execution and Data Movement: Theory and Practice
… are one of the oldest and fundamental cyber threats. They compromise the confidentiality of data, the integrity of program logic, and the availability of services. This threat becomes even severer when followed by other malicious activities such as data exfiltration. The integration of …

Data-driven Algorithms for Critical Detection Problems: From Healthcare to Cybersecurity Defenses
… groups and reduces biases. Cyber threats, such as ransomware and advanced persistent threats (APTs), have presented growing threats in recent years. Existing ransomware defenses often rely on black-box models trained on unverified traces, providing limited interpretability. To …

Classifying advanced malware into families based on instruction link analysis
… a big threat in today’s computing world such as Advanced Persistent Threats (APTs). APTs is customized for a specific target and can be subtly altered to avoid detection. In that, APTs attack is considered as a serious problem whose devastating effects cannot be overemphasized. To combat this …

ALFA-Chains: An Artificial Intelligence Approach to Exploit Chain Discovery in Networks
Exploit chains play a crucial role in advanced persistent threats (APTs) and other malicious cyber campaigns. Sophisticated attackers can navigate across a network, escalate their privileges, and compromise valuable targets by executing the right exploits in the right order. However, finding these …

Advanced Threat Intelligence: Interpretation of Anomalous Behavior in Ubiquitous Kernel Processes
… and sensitive data. With the emergence of advanced persistent threats (APTs), identifying and understanding such attacks has become an increasingly difficult task. Current signature-based systems are heavily reliant on fixed patterns that struggle with unknown or evasive applications, while …

Game-Theoretic and Machine Learning-based Defensive Deception for Dependable and Secure Cyber-Physical Systems
… face growing risks from sophisticated cyber threats, particularly Advanced Persistent Threats (APTs), which conventional security measures struggle to counter effectively. These threats can subvert controls or launch multi-stage attacks, compromising critical infrastructure. This dissertation …

A Multi-Agent Approach to Advanced Persistent Threat Detection in Networked Systems
Advanced cyber threats that are well planned, funded and stealthy are an increasing issue facing secure networked systems. As our reliance on protected networked systems continues to grow, the motivation for developing new malicious techniques that cannot be easily detected by traditional …

A novel flow-based statistical pattern recognition architecture to detect and classify pivot attacks
Pivot attack or pivoting is a well-known technique used by threat actors to cover their tracks and overcome connectivity restrictions imposed by the network defences or topology. Therefore, detecting ongoing pivot attacks while the opponent has not yet achieved their goals is essential for a solid …

Information-fusion-based methods to improve the detection of advanced cyber threats
… solutions to protect systems against malicious threats. Intrusion detection is an essential strategy that, together with intrusion prevention and response, make systems more resilient against malicious access. The challenges that are faced while developing intrusion detection systems (IDSes) are …
