Enquadramento
A major concern in many kinds of modern systems, such as web-based content and service provider infrastructures, is security. These systems are connected to the Internet through a number of external Internet Service Providers and are prone to situations such as Distributed Denial of Service (DDoS) attacks. Under such attacks, the system will exhaust its resources trying to serve a massive number of requests, rendering the service unavailable to legitimate clients. Currently, there are different techniques to avoid such kind of attacks, although they are not fully effective, since they rely on a human operator to decide when the defense mechanisms need to be activated, requiring permanent supervision of the system.
Objetivo
Extend Znn.com, a case study of a self-adaptive system news serving content that is able to dynamically manage resources to adapt to variability in service demand with self-securing capabilities. Znn.com is implemented using Rainbow, a platform for architecture-based self-adaptation. The work will concretely consist in extending Znn.com with the capability of facing DDoS attacks using the tools provided by Rainbow and validating the resulting prototype.
Plano de Trabalhos - Semestre 1
1. Analysis of the architecture of the Rainbow Framework and implementation of the Znn.com case study (2 months).
2. Analysis of Remote-Triggering Black-Hole (RTBH) technique to face DDoS attacks (3 weeks).
3. Initial design to build RTBH into Znn.com in terms of the mechanisms provided by Rainbow (1 month).
4. Modelling of the decision-making process regarding the detection of DDoS attacks and triggering of RTBH (1 month).
Plano de Trabalhos - Semestre 2
1. Implementation (2 months).
5. Experimentation (2 months).
6. Writing of final report (2 months).
The activities described in the different semesters may overlap in time
