Closing the loop of SIEM analysis to Secure Critical Infrastructures
Critical Infrastructure Protection is one of the main challenges of last
years. Security Information and Event Management (SIEM) systems are widely used
for coping with this challenge. However, they currently present several
limitations that have to be overcome. In this paper we propose an enhanced SIEM
system in which we have introduced novel components to i) enable multiple layer
data analysis; ii) resolve conflicts among security policies, and discover
unauthorized data paths in such a way to be able to reconfigure network
devices. Furthermore, the system is enriched by a Resilient Event Storage that
ensures integrity and unforgeability of events stored.Comment: EDCC-2014, BIG4CIP-2014, Security Information and Event Management,

Towards a Secure Smart Grid Storage Communications Gateway
This research in progress paper describes the role of cyber security measures
undertaken in an ICT system for integrating electric storage technologies into
the grid. To do so, it defines security requirements for a communications
gateway and gives detailed information and hands-on configuration advice on
node and communication line security, data storage, coping with backend M2M
communications protocols and examines privacy issues. The presented research
paves the road for developing secure smart energy communications devices that
allow enhancing energy efficiency. The described measures are implemented in an
actual gateway device within the HORIZON 2020 project STORY, which aims at
developing new ways to use storage and demonstrating these on six different
demonstration sites.Comment: 6 pages, 2 figure

Passive security threats and consequences in IEEE 802.11 wireless mesh networks
The Wireless Mesh Network (WMN) is ubiquitous emerging broadband wireless network. However, the open wireless medium, multi-hop multi-radio architecture and ad-hoc connectivity amongst end-users are such characteristics which increases the vulnerabilities of WMN towards many passive and active attacks. A secure network ensures the confidentiality, integrity and availability of wireless network. Integrity and availability is compromised by active attacks, while the confidentiality of end-users traffic is compromised by passive attacks. Passive attacks are silent in nature and do not harm the network traffic or normal network operations, therefore very difficult to detect. However, passive attacks lay down a foundation for later launching an active attack. In this article, we discuss the vulnerable features and possible passive threats in WMN along with current security mechanisms as well as future research directions. This article will serve as a baseline guide for the passive security threats and related issues in WMNs
