Anomaly Detection Reading Group: Graph Classification

Speaker: Andra Băltoiu (University of Bucharest)


Abstract: We continue our investigation on the task of detecting outliers in networks, by looking at the concept of signal variation on a graph.

Anomaly Detection Reading Group: Deep OC-SVM

Speaker: Andrei Pătrașcu (University of Bucharest)


Abstract: Recent empirical results confirm that one-class (OC) classification methods remain among the most important learning strategies for anomaly detection. In this seminar, we will technically describe in detail multiple basic OC schemes such as OC-SVM and SVDD and their deep variants, in order to identify room of improvements or generalization directions towards the graph anomaly detection context.

Protocols in Dynamic Epistemic Logic

Speaker:  Alexandru Dragomir (University of Bucharest)


Abstract: Dynamic epistemic logics are useful in reasoning about knowledge and certain acts of learning (epistemic actions). However, not all epistemic actions are allowed to be executed in an initial epistemic model, and this is where the concept of a protocol comes in: a protocol stipulates what epistemic actions are allowed to be performed in a model. The aim of my presentation is to introduce the audience to two accounts of protocols in DEL: one based on [1], and the second on [2].

Dynamic Code Analysis

Speaker:  Radu Velea (BitDefender)


Abstract: Static code analysis methods have the advantage of providing deterministic and reliable results. Malware has evolved beyond the point where simple pattern matching algorithms or signatures can provide adequate levels of protection. To respond to new threats we have to look at other hidden aspects such as execution behavior and fight evasive techniques by performing dynamic code analysis. This presentation discusses how to do this using runtime emulation and describes the existing challenges for the most popular architectures and executable file formats.

House of clouds – sau cum sa auditezi un sistem in cloud

Speaker: Georgel Gheorghe este absolvent al facultatii de Electronica, Telecomunicatii si Tehnologia a informatiei. Este membru ISACA si detine certificari precum CISA (Certified Information Systems Auditor), CGEIT (Certified in the Governance of Enterprise IT) si CRISC (Certified in Risk and Information Systems Control).

Are o experienta de peste 11 ani in audit si consultanta in industrii de tipologii diferite (servicii financiare, retail, productie, telecomunicatii, energie) cu proiecte precum: evaluari ale mediilor IT&IS, audituri de conformitate, evaluari ale configurarilor de securitate, managementul vulnerabilitatilor, managementul continuitatii afacerii, managementul schimbarilor.

Dupa mai multi ani petrecuti in Deloitte, Ericson si Mazars, s-a alaturat unei noi echipe unde cunostintele si experienta sa sunt o baza solida pentru identificarea unor solutii potrivite pentru noile provocari digitale.


Abstract: Prezentarea propusa, House of clouds – sau cum sa auditezi un sistem in cloud, va aborda aspecte relevante ce tin de intelegerea si delimitarea sistemelor in scop, identificarea riscurilor si selectarea masurilor de control necesare.

In introducere, Gratiela Magdalinoiu (presedinte ISACA Romania) va face o scurta prezentare ISACA Romania.
