Tactics Techniques and Procedures (TTPs) in cyber domain is an important threat information that describes the behavior and attack patterns of an adversary. Timely identification of associations between TTPs can lead to effective strategy for diagnosing the Cyber Threat Actors (CTAs) and their attack vectors. This study profiles the prevalence and regularities in the TTPs of CTAs. We developed a machine learning-based framework that takes as input Cyber Threat Intelligence (CTI) documents, selects the most prevalent TTPs with high information gain as features and based on them mine interesting regularities between TTPs using Association Rule Mining (ARM). We evaluated the proposed framework with publicly available TTPbased CTI documents. The results show that there are 28 TTPs more prevalent than the other TTPs. Our system identified 155 interesting association rules among the TTPs of CTAs. A summary of these rules is given to effectively investigate threats in the network.

There are many object oriented design patterns and frameworks; to make the Information System robust, scalable and extensible. The objected oriented patterns are classified in the category of creational, structural, behavioral, security, concurrency, and user interface, relational, social and distributed. All the above classified design pattern doesn't work to provide a pathway and standards to make the Information system, to fulfill the requirement of confidentiality, Integrity and availability. This research work will explore the gap and suggest possible object oriented design pattern focusing the information security perspectives of the information system. At application level; this object oriented design pattern/framework shall try to ensure the Confidentiality, Integrity and Availability of the information systems intuitively. The main objective of this research work is to create a theoretical background of object oriented framework and design pattern which ensure confidentiality, integrity and availability of the system developed through the object oriented paradigm.

Anwar, Z., Malik, A.W..  2014.  Can a DDoS Attack Meltdown My Data Center? A Simulation Study and Defense Strategies Communications Letters, IEEE. 18:1175-1178.

The goal of this letter is to explore the extent to which the vulnerabilities plaguing the Internet, particularly susceptibility to distributed denial-of-service (DDoS) attacks, impact the Cloud. DDoS has been known to disrupt Cloud services, but could it do worse by permanently damaging server and switch hardware? Services are hosted in data centers with thousands of servers generating large amounts of heat. Heating, ventilation, and air-conditioning (HVAC) systems prevent server downtime due to overheating. These are remotely managed using network management protocols that are susceptible to network attacks. Recently, Cloud providers have experienced outages due to HVAC malfunctions. Our contributions include a network simulation to study the feasibility of such an attack motivated by our experiences of such a security incident in a real data center. It demonstrates how a network simulator can study the interplay of the communication and thermal properties of a network and help prevent the Cloud provider's worst nightmare: meltdown of the data center as a result of a DDoS attack.
