Akamai: The Financial Sector Is Seeing More APIs-Based Attacks

Cyberattackers are now increasingly targeting APIs, especially in the financial sector, according to content delivery network Akamai’s between 15% and 30% of all web traffic. The Cambridge, Massachusetts-based company hAndy Ellis neatly summarized the resultsemail to VentureBeat, Akamai explained some of the advantages of automation: criminals “use bots and tools that allow threading, or multiple simultaneous connections, to attempt multiple logins at once.” And by targeting APIs, “they hope to avoid some front-end defenses and speed up their validation times.” A recent Franck V. on

Gen X Performance Tuning

We are using AMD 2nd Gen EPYC 7642 for our tenth generation “Gen X” servers. We found many aspects of this processor compelling such as its increase in performance due to its frequency bump and cache-to-core ratio. We have partnered with AMD to get the best performance out of this processor and today, we are highlighting our tuning efforts that led to an additional 6% performance.

Thermal Design Power & Dynamic Power

Thermal design power (TDP) and dynamic power, amongst others, play a critical role when tuning a system. Many share a common belief that thermal design power is the maximum or average power drawn by the processor. The 48-core AMD EPYC 7642 has a TDP rating of 225W which is just as high as the 64-core AMD EPYC 7742. It comes to mind that fewer cores should translate into lower power consumption, so why is the AMD EPYC 7642 expected to draw just as much power as the AMD EPYC 7742?

Let’s take a step back and understand that TDP does not always mean the maximum or average power that the processor will draw. At a glance, Continue reading

Upcoming Events and Webinars (March 2020)

Starting with a short message to anyone interested in our on-site events in Switzerland: on March 10th we’re running our first 2020 workshop, focusing on Docker and containers.

I totally reworked the material, adding tons of new Docker networking examples (including deep dive into iptables) and a few fun things like building an Ansible container, or starting the whole NetBox stack with a single command. Even if you don’t plan to deploy containers in your production network, you might drop by just for that part.

And now for the upcoming webinars:

Juniper EVPN BGP options – eBGP-only design

In another part of his never-ending EVPN/BGP saga Ivan Pepelnjak argued with Juniper fanboys once again about sanity of iBGP-over-eBGP and eBGP-over-eBGP designs and all that fun stuff. I’ve already written my opinion about that topic in my previous post and numerous comments to Ivan’s posts (TL;DR: iBGP-over-eBGP design has its advantages, just implement it wisely – don’t place RR on spine switches).

But there is one thing that worries me. In almost every one of his posts Ivan talks about some mythical Junos limitations that don’t allow Juniper to support eBGP only (over single session) design. So let’s find out what these limitaions are.

Juniper has freely available version of vQFX for Vagrant. There are a few lab topologies available on GitHub. I will be using full-2qfx-4srv-evpnvxlan topology in this post.

This topology comes with Ansible playbook that configures vQFX switches with iBGP-over-OSPF EVPN. Standard Juniper configuration, just for reference:

YAML

Yaml- YAML Ain’t markup langauge

The devices need a standard  protocol to communicate between each other , similarly there  is requirement of specific standard data format to communicate between application .YAML is one of the data format and is best known to be human friendly  means it’s easier to understand and write  for human compare to other well know data format such as JSON and XML

YAML document starts with 3 hyphen ‘—‘ at top ,it indicate beginning of YAML  document .

We can have mix data types in YAML, let’s see with an yaml example

ex1_ya.yaml

---
IOS: CISCO
JNOS: JUNIPER
CISCO:
  - Router
  - 7600
  - True
  - ['interface','ip address']

 First and second item i.e IOS: CISCO  and JNOS: JUNIPER is dictionary where ‘IOS’ and ‘JNOS’ is key and ‘CISCO’ and ‘JUNIPER’ is respective values

Third Item too is dictionary which comprises of list having different data type as below:

    ‘Router’ is string type.

     ‘7600’  is integer type

    ‘True’ is Boolean type

    Fourth item [‘interface’,’ip address’] is list  containing strings

Working with YAML using Python

The first and foremost thing to use YAML is to install PyYAML  , it’s  a YAML parser .
