What is security?

… protecting your servers, code, data, network, users from the bad guys

What is large scale?

Big infra (apps, servers, routers, firewalls), lots of stored data, lots of streaming data, partners

… so much that’s humanly impossible to manage or make sense out of .. and where traditional technologies fail to be of help

What is security @ large scale?When traditional security techniques fail. Too

many devices to manage. Too much logs. Many ways of getting attacked. Lots of applications.

Multiple programming stacks. Lots of code pushed out daily. Acquisitions. Mergers.

Outsourced Service Providers. 3rd party software.

DoS – a novice as well as a sophisticated attacker’s attack

Monitor, Learn, Adapt

The mystery of DDoS

Is it the holiday traffic or a botnet? Sometimes just being a difficult or

expensive target is a win… also called raising the bar

Aurora, Stuxnet

Use technology for it

Hadoop, MapReduce, Data Mining, CommonCrawler, Nutch, Splunk,

NodeJS, PhantomJS………

To win some battles, you need Avengers

Restrictive ACLs, Continuous Inventory Discovery, Proactive Vulnerability Detection, Patch

Management beyond at Web layer, Secure programming stack, Abuse Detection, Static

Analysis, Dynamic Analysis, Red Team, Trainings, Bug Recognition / Bounty program
