Critical Analysis on Advanced Persistent Threats

Defending Against Advanced Persistent Threats

Diagnosing Advanced Persistent Threats: A Position Paper

When a computer system is hacked, analyzing the root-cause (for example entry-point of penetration) is a diagnostic process. An audit trail, as defined in the National Information Assurance Glossary, is a securityrelevant chronological (set of) record(s), and/or destination and source of records that provide evidence of the sequence of activities that have affected, at any time, a specific oper...

Schemes for Surviving Advanced Persistent Threats

Mission critical systems are prevalent in the military and industry which renders them attractive as targets for security attacks. Their constantly increasing structural complexity contributes to benign faults and further facilitates malicious entities. Over the years, these malicious entities in cyber-space have grown smarter and extremely resourceful. Advanced persistent threat (APT) is a cle...

Protecting Industry 4.0 against Advanced Persistent Threats

The SADCIP project has arisen from the need to deal with increasingly intelligent and autonomous industrial and monitoring systems, capable of collaborating with each other to meet a common objective: provide efficient and real-time manufacturing and logistics from anywhere, at any time and anyhow [1]. However, any new condition that implies open communication with the Internet and the adaptati...

Defend against advanced persistent threats: An optimal control approach

The new cyber attack pattern of advanced persistent threats (APTs) poses a serious threat to cyberspace. This paper addresses the issue of defending against APTs in a cost-effective way. First, the APT-based cyber attack-defense processes are modeled as a type of differential dynamical systems. Then, the cyber defense problem is modeled as an optimal control problem. The optimal control problem...
