How to deternine what QRadar processes are using the most resources.
Is there a command I can run as a customer to help me understand when a certain process is running out of memory?
urlscan.io is a service to scan and analyse websites. When a URL is submitted to urlscan.io, an automated process will browse to the URL like a regular user and record the activity that this page navigation creates. This includes the domains and IPs contacted, the resources (JavaScript, CSS, etc) requested from those domains, as well as additional information about the page itself. urlscan.io will take a screenshot of the page, record the DOM content, JavaScript global variables, cookies created by the page, and a myriad of other observations.
Finally, urlscan.io will try to make a verdict whether the scanned website is considered malicious or suspicious. If the site is targeting the users one of the almost 400 brands tracked by urlscan.io, this will be shown in the scan results.

This document provides administrators and engineers guidance on securing Cisco firewall appliances, which increases the overall security of an end-to end architecture. The functions of network devices are structured around three planes: management, control, and data. This document is structured around security operations (best practices) and the three functional planes of a network. In addition, this document provides an overview of each included feature and references to related documentation. For the purposes of this document, all mentions of "Cisco firewall" refer explicitly to the Cisco ASA Adaptive Security Appliances, though the concepts may apply to other firewall and security devices.
What is the impact of initiating a Deploy Full Configuration on QRadar systems?
The Network Situational Awareness (NetSA) group at CERT has developed and maintains a suite of open source tools for monitoring large-scale networks using flow data. These tools have grown out of the work of the AirCERT project, the SiLK project and the effort to integrate this work into a unified, standards-compliant flow collection and analysis platform.
If you are new to the NetSA Security Suite, start with this overview of the components that comprise the NetSA Security Suite and their inter-operation.
CERT is a part of the Software Engineering Institute (SEI), a federally funded research and development center (FFRDC) operated by Carnegie Mellon University.

I am curious as to what is the average size or my events for disk space estimates. Is there a method to determine this in QRadar?
General overview of the Event Pipeline and Processes
Syslog Watcher installs a dedicated syslog server, integrating log data from multiple network devices into a single, easily manageable and accessible place. Collecting and analyzing syslogs is essential for maintaining network stability and auditing network security.
If your organization is using a security incident and event management (SIEM) server, you can integrate Office 365 Advanced Threat Protection with your SIEM server. SIEM integration enables you to view information, such as malware or phish detected by Office 365 Advanced Protection, in your SIEM server reports. To set up SIEM integration, you use the Office 365 Activity Management API.

Syslog messages from transit network devices can provide insight into and context for security events that may not be available from other sources. This insight aids in determining the validity and extent of an incident. Within the context of a security incident, administrators can use syslog messages to understand communication relationships, timing, and, in some cases, the attacker's motives and/or tools. These events should be considered complementary and should be used in conjunction with other forms of network monitoring that may already be in place.
Siphons cookies, exposes internal router & installs web backdoor on locked computers
The PowerShell execution policy is the setting that determines which type of PowerShell scripts (if any) can be run on the system. By default it is set to “Restricted“, which basically means none. However, it’s important to understand that the setting was never meant to be a security control.
FireEye’s Mandiant Incident Response and Intelligence teams have identified a wave of DNS hijacking that has affected dozens of domains belonging to government, telecommunications and internet infrastructure entities across the Middle East and North Africa, Europe and North America. While we do not currently link this activity to any tracked group, initial research suggests the actor or actors responsible have a nexus to Iran.
Cisco Talos recently discovered a new campaign targeting Lebanon and the United Arab Emirates (UAE) affecting .gov domains, as well as a private Lebanese airline company. Based on our research, it's clear that this adversary spent time understanding the victims' network infrastructure in order to remain under the radar and act as inconspicuous as possible during their attacks.
