Softpedia Job interview : Nicholas Lemonias on Satellite Conversation Vulnerabilities


Nicholas Lemonias, an details protection expert with Advanced Info Security Company and senior lecturer at a London college, has been investigating satellite interaction security.

He has written a analysis paper on the matter and he has been sort sufficient to present a lot more particulars on the subject in an job interview with Softpedia.

Softpedia: How did you occur up with the concept to analysis the stability of satellite communications?

Nicholas Lemonias: The determination of this thesis is technological evolution, and especially the evolution of data techniques, the swift progress of threats of the menace landscape.

This thesis relates to the fixing of the concern of in- ample security and the co- issue of Quality of services that must be equilibrated with safety, and as a result not be hindered as also place ahead by subject matter literature, referring to (Roy-Chowdhury et al., 2005).

The use of incompatible protection mechanisms for the provision of satisfactory safety in satellite networks, obvious Little bit Error transmission charges (BER), latency difficulties and Excellent of Support (QoS) degradation challenges. As a consequence, stability gets to be out of date, and an inconsiderable solution, even for satellite operators. < br />
Typical safety answers envisage the use of typical Conclude -to- End stability protocols, over the Internet Protocol Suite, and as a result constitute of an equilibrium trade-off among protection and Top quality of Services (QoS)

Thus the accumulation of end -to- conclusion stability protocols present fragmentary stability, at some sections of the satellite conversation mediums, are however also a main explanation for provider degradation.

My desire in Hacking and Facts Safety have inspired me to create this Thesis.

This thesis research is also dependent on previous matter literature which indicates that scientists of the College of Ruhr-Bochum have learned in a true experiment that the security of satellite programs is inadequate simply because it is in very clear - text as elaborated by issue issue literature.

The motivation of this analysis is also centered on various arguments that allege that security fl aws exist because of inherent vulnerabilities which at this phase 's believed to be a major barrier to sufficient stability (Saltzer et. al, 1975). Satellite communications depend on Internet protocols for protection, on the other hand this doesn&rsquot remedy the inherent stability difficulties.

The European Union has invested huge quantities of money for resolving safety difficulties in satellite communication and have produced calls for exploration in this discipline, however these challenges have not been solved, and as a result the quick advancement of safety threats have also achieved the satellite room sector.

In the previous few a long time information headlines and stories from govt departments, this kind of as the USCC (Congression) stated that two satellites programs belonging to the U.S authorities (LandSat- seven and Terra-AM1) were compromised in 2007-2008. The hackers are said to have taken complete management of the devices and this is also another evidence of the existent vulnerabilities in devices of Crucial Infrastructure.

Governments are reliant on personal corporations for the provision of satellite services, possibly for scientific or navy needs. Consequently for this reasons the thesis motivates for investigation in the area, with the all round intention of the functional implementation of Protection Confidentiality, Integrity and Availability which are crucial safety solutions.

Softpedia: What instruments have you employed in your work ?

Nicholas Lemonias: In our investigation we have applied Wire Shark for capturing and examining knowledge streams, but we have also employed common scientific methodologies these as ANOVA ( Evaluation of Variance) and ARC SIN Data Transformations to existing our evidences. For the graphs w e have used Excel and SPSS for some calculations.

Softpedia: What have you identified ? What kinds of vulnerabilities are there?

Nicholas Lemonias: A essential issue with satellite communications is that stability generates network congestions and for that reason cannot co-exist successfully with Performance Improvement Proxies or other accelerating agents, and hence therefore are contradictory in scope and operate.

Therefore in our analysis Thesis we address this dilemma with the creation of an first and incisive know-how that does not hinder the interoperation of accelerating brokers and helps make this inter- procedure far more subtle.

This new scientific prototype helps make use of the latest condition of the art Cryptography, particularly State-of-the-art Encryption Standard (AES). The effects from the experiments shown interoperable ranges of operate, with tiny delay.

Softpedia: What sorts of satellites are impacted by the vulnerabilities you've uncovered?

Nicholas Lemonias: This new technological innovation solves a pragmatic issue of non-interoperability involving safety co-existence with Efficiency Enhancement Proxies (PEP's). This vulnerability is existing - thanks to inherent flaws in the stability architecture of satellite devices.

This is a very long present vulnerability that the safety researcher group has not tackled beforehand. Consequently this new engineering provides a fully purposeful resolution that addresses this gap completely and effectively.

Softpedia: What are the pitfal ls ?

Nicholas Lemonias: The aforementioned vulnerabilities have long been existent and the protection group has mourned the lack of sufficient technologies to tackle the concern. Other technologies these as ML-IPSEC and MML-IPsec do exist and supply related answers, nevertheless they also produce plethora of other troubles, and the configuration is not so uncomplicated.

Softpedia: What should be performed to address the protection troubles ?

Nicholas Lemonias: The concerns arise thanks to inherent vulnerabilities in the architectural layout of Satellite techniques specifically subject subject literature by (Saltzer et. al, 1975) furnished a fundamental basis on how protection and computational system s must be intended, in conditions of safety, nevertheless this is presently missing in present patterns.

Present satellite protection models are much from the rules of Details Security, and as a result absence essential safety attributes. The application of Cryptography may provide extra levels of safety provision, this kind of as Confidentiality and Integrity, but that happens with out addressing the inherent protection vulnerabilities - proper at the core of the difficulty.

Softpedia: How challenging would it be to put into practice the changes you are proposing?

Nicholas Lemonias: The prototype presented works by using the Advanced Encryption Normal, and the way it functions by means of an alternative medium of conversation, it is comparatively easy and really configurable in conditions of adding extra en cryption procedures.

Softpedia: Have you tried out contacting the impacted parties (satellite makers or other entities) to see what they have to say about your function ?

Nicholas Lemonias: This vulnerability has extended been existing, but we haven't noticed any other engineering either from The Nationwide Aeronautics and Area Administration, the company of the United States Govt, or in academia. Some solutions are existent on the other hand these do not really deal with the inherent flaws right to the core of the challenge, as much as I know, and according to what is also posted on the Online.

Softpedia: In your belief, why haven&rsquot NASA or satellite businesses arrive up with a remedy to addressing this extended current vulnerability ?

Nicholas Lemonias: I really can't discuss for them, but someone who understands the challenge thoroughly, can see that inheritance of these vulnerabilities relate to causal result made by the safety composure of the devices. The application of Typical Security Protocols bridges the gap, but doesn't patch it at the main of the challenge.

Softpedia: When do you plan on publishing the analysis paper?

Nicholas Lemonias: This Thesis has by now been submitted to academia in fulfilment of my award, of Grasp of Science in Data Security. Even so there will also comply with a publication as a e-book, and submitted to tutorial portals in the in the vicinity of future.
