MLDS: Multi-Layer Defense System for Preventing Advanced Persistent Threats

Here we report on the issue of Advanced Persistent Threats (APT), which use malware for the purpose of leaking the data of large corporations and government agencies. APT attacks target systems continuously by utilizing intelligent and complex technologies. To overthrow the elaborate security network of target systems, it conducts an attack after undergoing a pre-reconnaissance phase. An APT at...

Preventing Advanced Persistent Threats in Complex Control Networks

An Advanced Persistent Threat (APT) is an emerging attack against Industrial Control and Automation Systems, that is executed over a long period of time and is difficult to detect. In this context, graph theory can be applied to model the interaction among nodes and the complex attacks affecting them, as well as to design recovery techniques that ensure the survivability of the network. Accordi...

Defending Against Advanced Persistent Threats

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...

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...
