Core Telemetries: Focus on the Right Data Sources to Achieve An Enterprise-Grade Security Monitoring Program
According to the most recent Verizon Data Breach Investigations Report, 73% of cyberattacks can be attributed to outsiders. This means that, generally speaking, the attacker will have to compromise an endpoint device and cross the enterprise threshold to accomplish their goals. Imagine a drive-by download that compromises a remote user’s laptop: the endpoint may run the malicious code, but the attackers still need to use the network to move laterally and access your data.
In this case, as in most attacks, the attack might have been detected on the endpoint as well as from any one of many other points within your environment. If your security monitoring system is able to collect sensor data from at least one of these points and if you’re able to monitor that data effectively, you’ll discover the attack and prevent a breach.
Each additional source of security data provides an extra layer of defense against cyberattacks. The deeper your defenses, and the more redundancy that’s built into them, the stronger your security monitoring program.
But even the most diligent SecOps teams are challenged by data overload. Teams report that less than 10 percent of the data they collect is analyzed.
Many organizations with limited resources find it challenging to prioritize security projects. Which data sources are most important? What solutions should be deployed first?
Build the Foundation with Endpoint Protection and Network Security Monitoring
If you haven’t already implemented it, setting up a basic endpoint protection platform (EPP) is a critical first step towards securing your network. EPP solutions allow you to collect, monitor, and analyze data from endpoint devices, reporting on known threats, preventing malware from executing, and in some cases quarantining unknown files until they can be investigated. Endpoint protection is relatively simple to deploy, and provides a valuable first layer of defense.
To improve visibility into your environment, consider adding a Network Intrusion Detection and Prevention Solution (NIDPS). Most NIDPS solutions rely on signatures to detect a broad range of threats, and are able to provide comprehensive network threat detection for your network, as well as from connected mobile and remote devices and cloud-based resources. NIDPS modules can be enabled within many Unified Threat Management (UTM) solutions as well, so you might actually already have a solution in place that you simply need to start monitoring.
Go Deeper With Advanced Solutions
If you’d like to improve upon the basic coverage offered by EPP and NIDPS, you can add one of today’s more advanced solutions, such as web proxy filtering and monitoring, URL filtering, email filtering (or anti-phishing solutions) or endpoint detection and response (EDR). These solutions can provide additional coverage of commonly exploited attack vectors (such as web browsers or email), or a more detailed record of the actions taken by the operating system. This can add up to deeper and more comprehensive coverage, but only if you are able to effectively monitor the larger amounts of log and event data they supply.
Boost Your Security Data Monitoring Capabilities With Security Analysis Software
Adding telemetries to your security stack can mitigate your risks and improve your security posture, but only if you are able to monitor those additional data sources continuously and effectively. Incorporating advanced solutions that you don’t have the time or ability to monitor doesn’t help.
And effectiveness in security monitoring is defined not by the number of data sources you monitor, but rather by how continuous and thorough your analysis of that data is.
This is where automated solutions can add the most value. The Respond Analyst can monitor sensor data from both foundational and advanced solutions. It’s able to work 24/7/365, and is capable of handling more events per hour than 14 human security analysts. The Respond Analyst is quick to deploy, and seamlessly integrates with a broad range of third-party security solutions, enabling it to ingest and monitor their data feeds without significant onboarding time, data tagging, or “training.”
The Respond Analyst enables smaller teams to monitor telemetries across their infrastructure—something they could not hope to accomplish manually. It makes it possible for smaller organizations to collect, monitor, and analyze security alerts and relevant contextual information on a scale that was previously available only to the largest enterprises. Along the way, the Respond Analyst brings advanced security capabilities within reach for businesses large and small, in numerous industries and verticals.
