Architecture Description Languages

(ADL) are used by System Designer as

a conceptual model



Focus is on ADLs for distributed

systems



They allow:



Rapid Prototyping



Direct Execution or simulation



Your task



Survey current ADLs



Categorize them based on their capabilities

(9)

 Publish/Subscribe is a hot candidate

 NextGen Internet  Distributed services

 Security & privacy is crucial requirement

 Confidential information  Anonymous comm.  Trust and authenticity

Privacy-preserving Publish/Subscribe

Motivation

Task

 Discover and survey new publications

 What it the SotA?

(10)

Machine Learning in Anomaly Detection:

Artificially intelligent techniques to detect intruders

Overview:

● Machine Learning: Techniques for extracting knowledge from data. ● Anomaly Detection: Intrusion detection using machine learning tools :)

● Are you interested in learning more about this field of Artificial Intelligence?

[email protected]

Goal:

•

Explore different tools and algorithms already used by anomaly detection systems.

•

Review what the latest papers are talking about.

•

Find different and current algorithms for supervised, unsupervised, semi-supervised and reinforcement learning.

(11)

Remote Exploits:

Techniques to detect and prevent them

Overview:

● Exploit: Programs that take advantage of bugs or vulnerabilities in a system. ● Remote Exploits: Exploits that work remotely over a network.

❏ Multiple techniques exist to try to detect remote exploitation attempts.

❏ Intrusion Detection Systems (IDS) already use some of these technologies.

Goal:

● Identify current techniques applied in modern Intrusion Detection Systems. ● Survey on state-of-the-art remote exploit detection technologies.

(12)



History: Two independent fields for enhancing ASR



HCI Field vs. NLP-field (Diphones vs. Word-relations)



Also other fields like robotics are active…



Task:



Identify the active fields where ASR is enhanced by topic / domain

identification



Create an overview about the promising fields on paper level for supporting

interdisciplinary activities



Starting Paper: Sorbello – Topic Recognition System, some further papers

available

Telecooperation 12

Topic: Speech-Recognition & „Topic

Recognition“

(13)

Data Correlation & Aggregation in

Collaborative Intrusion Detection Systems



IDS

:

Monitors a host or network and analyzes them for signs of intrusions

manifested by malicious behavior

or security policy violations



Collaborative IDS (

CIDS

): A number of IDS monitors

that collaborate by exchanging alert data



Motivation

: How to reduce the huge amount of alert

data that is exchanged over the CIDS?



Data correlation and aggregation techniques: similarity-based, attack

scenario-based, etc.



Goal

:

State-of-the-art of CIDSs data correlation & aggregation techniques

(14)

Defense Mechanisms of P2P Botnets



Overview:

Botnets: Infected machines/computers over the Internet (via Malwares) and turned into Bots/Zombies/Drones.

P2P botnets are very resilient to take downs

Recent botnets defend themselves upon recognizing they are being

investigated/probed



Goal:



State-of-the-art survey on P2P Botnet’s

defense mechanisms and countermeasures

How to work with Literature and

write Scientific Material

(17)

CONTENT



What’s a scientific publication?



Finding (good) references

Correct referencing



Writing your own paper



Reviewing papers

(18)



Basically a message

 With scientific background

 Offer a new insight of a scientific problem (solution)

OR a survey of a research field



The message is a claim

 That needs to be evaluated

AND validated

Leonardo Martucci - Telecooperation

What’s a scientific publication?

(19)



Books

 Survey (mostly) about a topic



Journal Articles

 Quality mostly depends on the Journal Good Journal Good Article

 Sometimes articles are outdated



Conferences and Symposia

 Quality is usually connected to the Conference Good Conference Good Paper

 The most recent research achievements

 http://core.edu.au/index.php/categories/conference%20rankings/1



Workshops

 Mostly for work in progress

 Good for discussing new ideas



Standard and RFCs

Types of Publications

(20)



Refer back to the original source of information

 For others to identify the foundations of your work

 Giving credit, when credit is due

Not doing so is REALLY bad practice aka plagiarism

 Grundregeln der wissenschaftlichen Ethik am Fachbereich Informatik

References and Referencing

(21)



Scientific publications

 Articles, papers, books



Standards

 RFC, ITU, IEEE, W3C etc.

+ All other non-scientific sources

 Surveys

 Magazines

 Reports

 Can I reference Wikipedia? or any other online material?

YES, but mind: not reliable (or stable) information sources

What should I reference?

(22)

1. First, define the message

 Objective of your publication define the area of research

2. Read the related work

 Define the work around your work

 Finding out what has been done

3. Implement your idea

 Evaluate your idea

 Validate your idea

4. Write your publication

Writing a Scientific Publication

3. Survey the related work

 Evaluate differences

 Identify trade-offs

 Introduce your own classification

(23)



Finding the message

 The most difficult part (!)

 Also, the creative one

going beyond the state of the art



A message that needs science

 Scientific foundations + challenges can be found in the related work

1. Your Work, Your Message

!

(24)



Related Work? Where?

 For the initial literature ask a researcher in the field it will give you a broad idea about the area

 Check publication repositories

ACM Digital Lib http://portal.acm.org/portal.cfm

IEEE Xplore http://ieee.org/portal/site

Google Scholar http://scholar.google.com

Academic Search http://academic.research.microsoft.com/

Conference directories http://www.dblp.org/search/

Authors’ home pages

 Other sources from the reference lists

REPEAT

2a. Related Work? Where? How?

(25)



Related Work ∞

 Identify the relevant sources

 Evaluating the importance of a publication 1. Read the abstract

2. Check the reference list 3. Read the conclusions 4. Read the rest



Related work will

 Compare your results against their results

 Be used as input for a survey

2b. Related Work and Relevance

Good Good Good Paper Read Next Paper No Yes Yes Yes 25

(26)



A reference looks like this:

 there are also other reference styles

 if you use LaTeX to write your report, have a look at BibTeX.

Referencing: doing it right

authors

title

how was it published (proceedings)

publisher date page number

(27)



Always have a good paper structure

 Organize your ideas

 Organize your papers

Define it BEFOREstarting to add text

 Plan the content of each section



Writing skills

 No one learns without doing it General Guidelines:

 Be concise (dt. “prägnant”)

 Be precise (dt. “präzise”)

4. Write your Publication

(28)



Peer-reviews

 Peers review your work and verify its general quality

 Evaluate the work before being published

 Offer suggestions to improve the work (!)



How’s quality defined

in a publication?*

 Novelty  Soundness Evaluation + Validation  Completeness  Readability

Peer-reviews

* it sometimes depends on the venue

28



What to write

 Positive and negative aspects of the work

 Constructive criticism (if possible)

 Offer suggestions to improve the paper e.g. additional literature

 Suggest an overall evaluation of the work



It is

NOT

the reviewer’s work

 to correct the publication!

(29)



A scientific publication is a

message

, a

validated claim



Refer to the original source of information,

avoid plagiarism



The peer-review should help, not criticize

Leonardo Martucci - Telecooperation 29

Summary

Good Good Good Paper Read Next Paper No Yes Yes Yes

1. Read the abstract

2. Check the reference list

3. Read the conclusions
