His presentation title is “Intent-Based Networking: Another Round of Hype?”
Remember Software Defined Networking (SDN)? It’s so last year – the industry has moved on to intent-based networking… which is often nothing more than another pile of hype.

The presentation will answer these questions:
  • Does “intent-based networking” mean anything?
  • Does it do more than manage device configurations?
  • Why is it so important to have feedback loops and post-change validation?
We’ll also touch on unicorns like machine-learning-driven intent and automated remediation, and try to figure out what could go wrong in an intent-based orchestration system.

His presentation title is “WiFi DesignPro – Power vs Sensitivity and EM wave propagation complexity”
Nowadays, with the implication of WiFi connectivity and the growing number of connected devices, planning freedom is tightened with the help of professional software tools that fail to anticipate all the disturbing WiFi wireless network environment parameters. Presentation will emphasize issues of transmitting / receiving characteristics of WiFi access points in the “friendly” and “hostile” environments of the EM Wave propagation, and consequently the awareness of the importance of the baseline requirements for the design and deployment of wireless WiFi points in complex environments.

Existing WiFi networks can be improved with new admissions and their usability is extended. Additional skills rae required from the planner and the practitioner. With clear requirements and desires, a modern wireless network predicts useful coverage and number of users as a challenge. In the short presentation, problems will be presented.

Arnold Nipper, Chief Technology Evangelist: DE-CIX (GER)

Arnold Nipper is in the Internet industry since 1989. He was instrumental in setting up RIPE, DeNIC and the academic and research IP network in Germany while working at one of the first commercial ISP in Germany.

SINOG (Slovenian Network Operators Group) je neodvisna skupnost, ki združuje omrežne strokovnjake različnih področij. Ustanovljena je bila z namenom povečati kakovost, učinkovitost, stabilnost in varnost slovenskih omrežij in omrežnih storitev ter dejavno vzpodbujati izmenjavo idej, znanja in dobre prakse med strokovnjaki v Sloveniji ter širše. Srečujemo se na letnem srečanju, polletnih tematskih delavnicah in mesečnih »Meetup« srečanjih. Osrednji dogodek skupnosti je letno SINOG srečanje, ki bo letos že šesto po vrsti.

Sprva smo letna SINOG srečanja organizacijsko pridružili slovenskemu IPv6 srečanju, ki je bil do nedavna največji osrednji dogodek v slovenskem in tudi širšem regijskem prostoru, namenjen spremljanju napredka in dosežkov ter izmenjavi dobrih praks pri prehodu na protokol IPv6 v organizacijah in poslovnih okoljih. Zadnji dve leti pa sta IPv6 in SINOG srečanje združeni pod enotnim imenom – SINOG srečanje.

Ker cenimo in spoštujemo vaš čas smo se letos na vašo željo odločili, da strnemo vsa predavanja na en dan in vam tako omogočimo lažjo udeležbo na vseh predavanjih SINOG srečanja. 

SINOG 6.0 srečanje nadaljuje dobro prakso predhodnih IPv6 in SINOG srečanj in združuje visoko-tehnološka predavanja vrhunskih mednarodnih in domačih strokovnjakov o aktualnih izzivih, reševanju le-teh in kratke predstavitve dosežkov domačih podjetij in organizacij.

Tematska delavnica o prepoznavanju in odzivanju na anomalije v omrežju

Omrežne strokovnjake in SINOG skupnost vabimo na tematsko delavnico SINOG 5.1 z naslovom “Prepoznavanje in odzivanje na anomalije v omrežju”.

Delavnica bo v četrtek, 4. aprila 2019, s pričetkom ob 16.30, v Veliki predavalnici Instituta “Jožef Stefan”, Jamova 39, Ljubljana.

Tematska delavnica bo obravnavala izzive, ki jih imajo tehniki pri zaznavanju anomalij v omrežju in kako se odzivati na konkretne varnostne grožnje. Nekatere anomalije prepoznamo hitro z dokaj enostavnimi orodji, pri drugih pomagajo le kompleksna orodja in veliko prakse ter inženirskega znanja. V delavnici bodo predstavljeni trije različni pristopi in dobre prakse, ki se izvajajo v poslovnem in operaterskem okolju.

Prepoznavanje in odzivanje na anomalije v omrežju

Bojan Zajc
Sodobna požarna pregrada in Layer 7 – ko potrebujemo več, kot le prepoznavo aplikacije

Kaj so požarne pregrade, danes bolj ali manj vsakdo ve. Razmeroma malokdo pa ve, da so nekatere nekoliko bolj ‘dlakocepske’, kakor druge. V bistvu je poznavanje različnih vrst požarnih pregrad in principov njihovega delovanja / razlik med njimi na izredno nizkem nivoju in vedno znova naletim na presenečenje, ko nekomu razlagam, kaj WatchGuard požarne pregrade zmorejo.

Tzv. ‘Enterprise’ požarne pregrade se s tem ne ukvarjajo, saj predvidevajo, da bomo to reševali z drugimi specializiranimi rešitvami. WatchGuard, ki je specialist za SME in močno distribuirana Enterprise okolja, pa je ravno na tem področju izredno močan. Pri odkrivanju anomalij, pa gre dinamično blokiranje z roko v roki z Dimension (u:demo p:visibility) – njihovim brezplačnim log&report strežnikom, kjer v Security dashboard-u potem lepo vidimo rekapitulacije najbolj pogosto blokiranih naslovov, protokolov, aplikacij, uporabnikov,…. Ko tu neke številke bistveno odstopajo od povprečja, hitro vemo, kaj moramo preveriti.

Inšpekcija prometa na L7 z aplikacijsko logiko je tu ključnega pomena, saj ravno ona generira tiste zadetke, kateri na koncu v Dimension statistiki ‘ven skačejo’ in pritegnejo našo pozornost.

Behaviour and anomaly detection

Look into how Network Telemetry and Cisco Stealthwatch work together to illuminate fundamental security gaps deep within a network. Learn how you can leverage your deployed network as a vast, enterprise-wide automated sensor grid to protect against advance zero-day threats, detect anomaly changes in host behaviour, segmentation violations within your network and much more.


Vladimir Ban
Umetna inteligenca oz. kako zaznati napade, ki jih nihče ne zazna?

Anomalije v omrežju so lahko že same po sebi idealne za zaznavanje groženj in napadov. Pravi izziv ni kako narediti povezavo iz zaznane anomalije in neke konkretne varnostne grožnje. Pravi izziv je, kako anomalijo sploh zaznati. Nekatere anomalije lahko zaznamo na preprost način in s preprostimi orodji, nekatere pa so “navadnim” očem skrite.

Kdaj je sploh anomalija koristna ali celo potrebna za zaznavanje varnostnih groženj in na kakšen način lahko zaznavamo kompleksne anomalije, si bomo v teoriji in praksi pogledali v tem predavanju.
