Faster than a speeding bullet: Geolocation data and account misuse
by Tim Collyer - December 1, 2014
Today's global economy and mobile workforce have a large impact on modern network security, elevating the importance of a "defense in depth" approach. Geolocation information has become an important element to monitor as part of such a layered defense. Incorporating geolocation information into network security programs does not necessarily require additional expenditure if the appropriate resources (such as a SIEM) are already in place. By tracking the geographic location for account logins, it is possible to discover anomalies by calculating the distance between two logins from the same account.

Mastering the Super Timeline With log2timeline
by Kristinn Guðjónsson - August 25, 2010
Timeline analysis is a crucial part of every traditional criminal investigation.

The same applies in the digital world, timeline information can provide a computer forensic expert crucial information that can either solve the case or shorten the investigation time by assisting with data reduction and pointing the investigator to evidence that needs further processing. Timeline analysis can also point the investigator to evidence that he or she might not have found using other traditional methods.

Effective Use Case Modeling for Security Information & Event Management
by Daniel Frye - March 10, 2010
With todays technology there exist many methods to subvert an information system which could compromise the confidentiality, integrity, or availability of the resource. Due to the abstract nature of modern computing, the only way to be reliably alerted of a system compromise is by reviewing the systems actions at both the host and network layers and then correlating those two layers to develop a thorough view into the systems actions. In most instances, the computer user often has no indication of the existence of the malicious software and therefore cannot be relied upon to determine if their system is indeed compromised.
SIEM Based Intrusion Detection with Q1Labs Qradar
by Jim Beechey - February 18, 2010
Attackers continue to find new methods for penetrating networks and compromising hosts. Therefore, defenders need to look for indications of compromise from as many sources as possible. Collecting and analyzing log data across the enterprise can be a challenging endeavor. However, the wealth of information for intrusion detection analysts is well worth the effort. SIEM solutions can help intrusion detection by collecting all relevant data in a central location and providing customizable altering and reporting. In addition, SIEM solutions can provide significant value by helping to determine whether or not an incident occurred. The challenge for analysts is creating effective alerts in order to catch todays sophisticated and well funded attackers.

Configuring and Tuning Cisco CS-MARS
by John Jarocki - January 4, 2008
CS-MARS (Cisco Security Monitoring, Analysis and Response System) and referred to as MARS, receives real-time alerts from IDS sensors, firewalls, Windows domain controllers, and many other devices. SNMP traps and syslog alerts can be forwarded to MARS, and vulnerability scanning information can also be imported. MARS groups events into sessions, and it uses endpoint vulnerability and network topology information to identify false positives automatically when possible. For example, an IDS sensor might report a PC attempting peer-to-peer file sharing, but the firewall log shows those packets were dropped . CS-MARS would mark this as a System Identified False Positive. In another case, a Windows RPC DCOM Overflow might be seen by an IDS system, but the target vulnerability scan shows the host is not running an affected version of Microsoft Windows another false positive (at least for the attack itself). From mountains of IDS, IPS, firewall, router, and system event logs, a properly tuned CS-MARS installation produces a correlated set of incidents that are likely to need real attention. The key to this degree of data reduction is the proper configuration and tuning of the CS-MARS device. The following configuration and tuning steps will be covered in depth, based on tuning work done by the author and his team in a large, worldwide installation.

Log Management SIMetry: A Step by Step Guide to Selecting the Correct Solution
by Jim Beechey - October 24, 2007
The information security profession continues to evolve and advance as organizations place greater value on their information security programs. These programs have grown significantly in the past few years, especially in small to medium sized organizations. Technical solutions such as: firewalls, VPNs, antivirus, patch management systems, intrusion detection/preventions systems and vulnerability scanners have all helped to address specific security issues. These technologies have also created a mountain of alerts and logs requiring a significant time investment to properly address important issues. As compliance, incident response and an increasing demand for IT security efficiency become more prevalent, organizations struggle with how to manage these disparate technologies efficiently and effectively. This is where a security information and event management system can help solve some of those challenges.
