How do small and medium-sized enterprises (Smes) within the UK prepare for and manage the consequences of a cyber-attack? A study on cyber resilience
Cyber resilience is essential for Small and Medium-Sized Enterprises (SME), those with fewer than 250 employees, to protect themselves against cyber-attacks and to ensure their continued operation. This research focusses on how United Kingdom (UK) based SMEs prepare for and manage the consequences …

Measurements Associated With Learning More Secure Computer Configuration Parameters
To defend against a cyber attack in which the attacker searches the network for vulnerable machines, most people will install some specific security software that cost some money, or download the newest patches for the softwares to avoid some vulnerabilities. Neither way can be efficient especially …

Fundamental limit of network flow attacks
A network flow-based attack refers to a cyber-attack where the adversary seeks to block user traffic from transmission by sending adversarial traffic that reduces the available user capacity. In this thesis, we explore the fundamental limits of network flow attacks by investigating its feasibility …
