KNOW YOUR ENEMY, KNOW HIS SWORD.― Miyamoto Musashi
Last month I delivered a talk at CyberSecurePakistan’15 conference and made an attempt to shed light on a blackspot in our corporate network security monitoring (NSM) practices.
In the face of ever growing sophisticated and targeted attacks the Network Security Monitoring (NSM) practices are becoming less concerned about intrusion analysis and more about playing Whac’a Mole.
The following stats which are derived from real life security incident response operations depicts a clear version of the problem.
The above graph from Verizon Data Breach Investigation Report (DBIR) report maps compromise and discovery activities which took days or less. Around 80% of intrusions took days or less to compromise a network but only 20% were discovered in days or less of time frame.
In 60% of cases, attackers are able to compromise an organization within MINUTES – Verizon DBIR 2015
What’s the norm for rest of 80% discoveries which didn’t take place in days or less?
According to Mandiant’s incident response experience in fortunate 100 companies it takes roughly 7 months to just discover the breach. The longest intrusion discovery time is 8 years (2,982 days).
Question to ask!
Where the heck are we disposing forensic artifacts for these intrusions?
The only reason we aren’t able to detect an intrusion for months is that either we aren’t acquiring enough artifacts or we are not processing them the right way.Continue reading

I will be taking FOR408 course at SANS first Digital Forensics and Incident Response (DFIR) themed training conference dē-‘fәr-‘kän / DFIRCON 2014. I will be participating via Simulcast as I don’t have the luxury to attend the conference live in Monterey, CA.
However, the best news I’ve heard is that SANS Institute has recently announced the new version of their Digital Forensics course FOR408 Computer Forensic Investigations – Windows in-depth.

The training is now renamed to “Windows Forensic Analysis” , however, new title isn’t the only change. Here is what SANS says about it
This course utilizes a brand-new Windows 8.1 based case exercise that took over 6 months to create the data. Realistic example case data takes months to create in real time correctly. The example case is a Windows 8.1 based image that has the subject utilize Windows Phone, Office 365, Sharepoint, MS Portal Online, Skydrive/Onedrive, Dropbox, and USB external devices. Our development team spent months creating an incredibly realistic scenario. The case demonstrates the latest technologies an investigator would encounter analyzing a Windows operating system. The brand new case workbook, will detail the step-by-step each investigator could follow to examine the latest technologies including Windows 8.1.
So, I believe I’m right on time :) Course material arrived yesterday and I’m feeling excited to get onto the training.
