Charles Leaver – Ask These 6 Questions For Damage Control Before A Cyber Attack

Written By Michael Bunyard And Presented By Ziften CEO Charles Leaver

The reality of modern-day life is that if cyber hackers wish to breach your network, then it is just a matter of time before they will be successful. The endpoint is the most typical vector of attack, and individuals are the greatest point of vulnerability in any company. The endpoint device is where they connect with whatever information that a hacker seeks: intellectual property, information, cyber ransom, and so on. There are brand-new Next Generation Endpoint Security (NGES) systems, where Ziften is a leader, that supply the needed visibility and insight to assist minimize or prevent the opportunities or period of an attack. Methods of prevention consist of lowering the attack surface area through removing known vulnerable applications, curtailing version proliferation, eliminating destructive processes, and ensuring compliance with security policies.

However prevention can only go so far. No solution is 100% effective, so it is important to take a proactive, real time methodology to your environment, viewing endpoint habits, identifying when breaches have taken place, and reacting instantly with remediation. Ziften likewise provides these abilities, typically known as Endpoint Detection and Response, and organizations should alter their frame of mind from “How can we avoid attacks?” to “We will be breached, so exactly what do we do then?”

To understand the true breadth or depth of an attack, companies have to be able to rewind the clock and rebuild the conditions surrounding a breach. Security investigators need answers to the following 6 questions, and they need them quickly, given that Incident Response officers are outnumbered and handling restricted time windows to reduce damage.

Where was the cyber attack behavior initially seen?

This is where the capability to look back to the point in time of preliminary infection is critical. In order to do this effectively, organizations have to have the ability to go as far back in history as necessary to determine patient zero. The regrettable state of affairs in accordance with Gartner is that when a cyber breach happens, the typical dwell time prior to a breach is found is a stunning 205 days. In accordance with the 2015 Verizon Data Investigations Breach Report (DBIR), in 60% of cases, cyber attackers had the ability to permeate organizations within minutes. That’s why NGES systems that do not continually monitor and record activity but rather periodically poll or scan the endpoint can lose out on the preliminary important penetration. Likewise, DBIR found that 95% of malware types appeared for less than four weeks, and 4 from five didn’t last 7 days. You need the ability to continually monitor endpoint activity and recall in time (however long ago the attack occurred) and reconstruct the preliminary infection.

How did it act?

What happened piece by piece after the preliminary infection? Did malware execute for a second every five minutes? Was it able to obtain escalated privileges? A constant image of what took place at the endpoint behaviorally is critical to get an investigation began.

How and where did the cyber attack disperse after preliminary compromise?

Normally the enemy isn’t after the details readily available at the point of infection, however rather want to utilize it as a preliminary beachhead to pivot through the network to get to the valuable data. Endpoints include the servers that the endpoints are connected to, so it is essential to be able to see a complete image of any lateral motion that occurred after the infiltration to know exactly what assets were jeopardized and potentially likewise contaminated.

How did the infected endpoint(s) behavior(s) change?

Exactly what was going on before and after the contamination? What network connections were being attempted? Just how much network traffic was flowing? What processes were active prior to and after the attack? Immediate answers to these concerns are critical to fast triage.

What user activity took place, and was there any potential insider involvement?

What actions did the user take before and after the infection happened? Was the user present on the device? Was a USB drive inserted? Was the time period outside their normal usage pattern? These and many more artifacts must be offered to paint a complete image.

What mitigation is needed to deal with the cyber attack and prevent another one?

Reimaging the contaminated machine(s) is a lengthy and costly solution however many times this is the only way to know for sure that all hazardous artifacts have been removed (although state-sponsored attacks might embed into system or drive firmware to stay immune even to reimaging). But with a clear picture of all activity that took place, simpler actions such as getting rid of malicious files from all systems affected might suffice. Re-examining security policies will most likely be necessary, and NGES solutions can assist automate future actions should comparable scenarios emerge. Automatable actions consist of sandboxing, cutting off network access from infected devices, eliminating processes, and a lot more.

Don’t wait till after a cyber attack takes place and you need to call in an army of experts and spend your time and cash piecing the realities together. Ensure you are prepared to respond to these six crucial concerns and have all the responses within your grasp in minutes.
