![]() ![]() I consider this a “phase 0” transformation because it does not require architecting in a new solution. As an incident responder, my goal is to both satisfy the logging needs for what is most commonly needed for ATT&CK detection as well as what is most useful for an IR engagement. The ATT&CK matrix is a framework that defines the tactics and techniques that an attacker may use to advance towards their goals. Let’s start with the MITRE ATT&CK® framework that has input from the global security community. After the why comes the what, which is the importance of what we can log. I want to put my experience into the hands of those who haven’t yet compiled the mountains of possibilities. This quote sums up why I’m writing this blog. “Hope in the form of glorious combat, battle is the great redeemer, the fiery crucible in which the only true heroes are forged.“ - Master Sergeant Farell from Edge of Tomorrow When the machine goes production, do you know if it will satisfy an incident responder’s needs? How sure are you that attacker actions are sufficiently recorded when you learn an attacker deployed ransomware from your domain controller? Have your logs run the IR gauntlet? The point is that log configurations are often not oriented to benefit a future investigation.įor mature environments, log configuration input may come from a compliance team, information security, or a commercial product as an automatic default build. ![]() Responsibilities may also extend to architecture, including both physical components and virtual environments. If the who is your Windows administrators, then while priorities can vary by role, typical responsibilities include maintaining a Windows domain and applications, ensuring access to business resources, meeting uptime SLAs, patching operating systems and applications, and satisfying audit compliance. Security Operations Center (SOC) Analystįor this reason, it’s important to understand who architected your current log configuration and why.It depends on what they are set to store or ignore, with the definition of proper logging differing by role: Their effectiveness, however, is another story. Whether raw or ingested into a SIEM, they are what incident responders most commonly request. While many artifacts exist across these disciplines, it’s Windows event logs that provide the most bang for the buck on endpoints. Each source has its own strengths and weaknesses, and artifact gathering is a team sport that engages network engineering, Windows and Linux administration, and cloud teams. In digital forensics, we look for traces in memory, on the network, or within any of a number of filesystem artifacts on disk. While breaches come in many different forms-ransomware, intellectual property theft, defacement-incident responders look for one commonality: traces of an attacker.Īccording to Locard's exchange principle, in physical forensics, every contact leaves behind a trace-for example, fingerprints, blood, or a shoe impression.
