“…The introduction of LigtVN [37] promises better performance but the efficiency is still limited to running at most twenty network nodes in one deployment on a rather capable server machine. Both V-NetLab and LightVN have a promising architecture but still cannot be deployed in a lightweight and portable manner to enable easy setup migration and versioning.…”

Subject reviewSecurity attacks are becoming a standard part of the Internet and their frequency is constantly increasing. Therefore, an efficient way to research and investigate attacks is needed. Studying attacks needs to be coupled with security evaluation of currently deployed systems that are affected by them. The security evaluation and research process needs to be completed quickly to counter the incoming attacks, but this is currently a complex and timeconsuming procedure which includes a variety of systems and tools. Furthermore, as the attack frequency is increasing, new security specialists need to be trained in a comprehensible and standardized way. We propose a new approach to security evaluation and research that uses scalable network emulation based on lightweight virtualization implemented in IMUNES. This approach provides a unified testing environment that is efficient and straightforward to use. The emulated environment also couples as a portable and intuitive training tool. Through a series of implemented and evaluated scenarios we demonstrate several concepts that can be used for a novel approach in security evaluation and research.

Zbog toga je potrebno razviti metodu za učinkovito istraživanje i analizu takvih napada. Proučavanje napada potrebno je izvoditi u sprezi s procjenom sigurnosti računalnih sustava na kojima se u tom trenutku izvršavaju napadi. Procjena sigurnosti i proces istraživanja moraju se moći obaviti u kratkom vremenu zbog što brže zaštite od dolazećeg napada. Trenutno je to kompleksan i vremenski zahtjevan zadatak koji uključuje širok raspon sustava i alata. Također, budući da se učestalost napada povećava, novi sigurnosni stručnjaci moraju se obučavati na način koji im je razumljiv i standardiziran. Predlažemo novi pristup procjeni sigurnosti i istraživanju koji koristi skalabilnu emulaciju mreže zasnovanu na virtualizaciji korištenoj u alatu IMUNES. Ovakav pristup pruža ujedinjenu okolinu za testiranje koja je efikasna i jednostavna za korištenje. Emulirana okolina također može služiti kao prenosiv i intuitivan alat za podučavanje i vježbu. Kroz niz implementiranih i analiziranih scenarija, pokazali smo određene koncepte koji se mogu koristiti za novi pristup u procjeni i istraživanju sigurnosti.

“…In this latter case, it would be possible to host multiple virtual networks over a single underlyingnetwork infrastructure. Developers should take care to prevent thetraffic and settings of these virtual networks from being interfere witheach other.This approach is supposed to provide more costeffective and scalable architecture [6].…”

“…However, using real testbeds involves important challenges like the need of a reasonable amount ofinvestment, difficulties regarding flexibility and scalability, and the securitythreatsthat they can impose to the public network. In spite of the possibility of reducing these security threats by isolating the testbed from the public network, this can result in considerable difficulties in remote accessing of thetestbedfrom the public network [6], [7].…”

Abstract--Information security now is considered to be cross-disciplinary and comprehensive field. It integrates the accumulation of knowledge in many disciplines like computer science, mathematics, communications, electronics, physics, etc. Thus, there has been an ongoing effort to improve the experiences in information security experimentation. Many international institutions are investigating enhanced approaches to provide hands-on learning and research environments. However, academic institutions are facing with the difficult challenge of providing lab infrastructuresthat meet the increasingly growing needs of cybersecurity training. In this paper, we report on the necessity and importance of building an effective national testbed for cybersecurity experimentation. We also present a general top-level architecture for this testbed emphasizing the most important enabling technologies.
