Oops!

What happened next?

Ok, not that bad
errors in Checks
Errors in
Specs
Thresholds
too low
Incidents!

What to do?
Troubleshoot
Call the developer
Request help
from developer teams

Access To
A developer

Fixed it - all good nao
GOT IT
Working!
happily
ever

Set &
Forget
Or…???

maintenance

Conclusions

What did we Learn?
START with firewall ports / VPN connections.
access to a test environment
experienced tester.
Test thoroughly.

Think the checks through
very clear specifications
Remember:
Every 5 minutes

More lessions learned
A good programmer
Plan for THE aftermath,
log book &
Script Repository
Plan for improvements

But
most important
of all

No 1

Tips & tricks

Basic troubleshooting
Run check locally on host
( In solaris : as nagios USER + root )
RUN “Test check command”
in console
Check HOST config files
Solaris: /etc/nagios/nrpe.cfg
Windows: C:Program FilesNSClient++NSC.ini
Check HOST logs
Solaris: /var/adm/nrpe
Windows: C:Program FilesNSClient++nsclient.log
/etc/nagios/nrpe.cfg
/etc/nagios/nrpe.cfg

5 Bare Minimum Things A Web Startup CTO Must Worry About

So you have started-it-up and now you are getting good traffic — Thousands of users, etc. etc. Do you know script kiddies are scanning your website using simple dictionary attacks on SSH ports? Do you know that once in a while there is a Fatal application Error in your PHP log (which may point to bigger problem)? Do you know that the backup you are taking is actually not gonna restore your DB? Do you know that every night at 12 one of the servers has a CPU spike? It’s a good idea to catch some of the serious problems early on and deploy tools to proactively assess them. In this session we will discuss some very basic things, as a CTO you MUST worry about and proactively solve problems around them. These are (in the order of decreasing priority): 1. Security 2. Monitoring/Availability/Load (External/System level) 3. Application errors 4. Backup 5. Source control

44CON 2014 - Stupid PCIe Tricks, Joe Fitzpatrick

44CON 2014 - Stupid PCIe Tricks, Joe Fitzpatrick. Hardware hacks tend to focus on low-speed (jtag, uart) and external (network, usb) interfaces, and PCI Express is typically neither. After a crash course in PCIe Architecture, we’ll demonstrate a handful of hacks showing how pull PCIe outside of your system case and add PCIe slots to systems without them, including embedded platforms. We’ll top it off with a demonstration of SLOTSCREAMER, an inexpensive device that’s part of the NSA Playset which we’ve configured to access memory and IO, cross-platform and transparent to the OS - all by design with no 0-day needed. The open hardware and software framework that we will release will expand your Playset with the ability to tinker with DMA attacks to read memory, bypass software and hardware security measures, and directly attack other hardware devices in the system.

"Competent Analysts will require adequate networking knowledge, diligent security testing skills, and critical thinking skills to assure factual data collection creates factual results through correlation and analysis." - OSSTMM v3 Il Network Penetration Test (NPT) ha lo scopo verificare la sicurezza dei sistemi esposti sulla rete. Viene valutata la presenza di controlli - e la loro corretta implementazione - che annullano o limitano le minacce esistenti verso i beni dell'organizzazione. L'attività valuta uno scenario specifico che varia secondo il bersaglio, la posizione degli attaccanti e le informazioni in possesso al personale coinvolto. Un Penetration Test si esegue tramite varie attivtà spesso molto delicate e importanti e, come ben specificato nell'Open Source Security Testing Methodology Manual (OSSTMM), gli analisti non solo devono avere delle competenze adeguate della rete e dei suoi protocolli ma anche applicare un ragionamento critico per raccogliere e correlare le informazioni in maniera corretta così da ottenere risultati oggettivi. Durante il seminario verrà introdotta la metodologia OSSTMM, con particolare attenzione alle reti TCP/IP (Data Networks) e alle operazioni tipiche per la ricerca degli host sulla rete e l'identificazione dei servizi interattivi.

It's no secret that python is fantastic when it comes to rapid prototyping and development. When it comes to deploying a web application, the road to glory isn't as well paved and navigating the array of techniques and tools can be daunting. This talk will address the advantages of continuous deployment, the success factors involved and the tools available, mainly focusing on experiences with Django web development.

Open Source Monitoring Tools Shootout

Open Source Monitoring Tools Shootout

Open Source Monitoring Tools Shootout

The Open source market is getting overcrowded with different Network monitoring solutions, and not without reason, monitoring your infrastructure become more important each day, you have to know what's going on for your boss, your customers and for yourself. Nagios started the evolution, but today OpenNMS, Zabix, Zenoss, Groundworks, Hyperic and different others are showing up in the market. Do you want lightweight, or feature full, how far do you want to go with your monitoring, just on os level, or do you want to dig into your applications, do you want to know how many query per seconds your MySQL database is serving, or do you want to know about the internal state of your JBoss, or be triggered if the OOM killer will start working soon. This presentation will guide the audience trough the different alternatives, based on our experiences in the field. We will be looking both at alerting and trending and how easy or difficult it is to deploy such an environment.
