System Monitor or Sysmon is a Windows system service and device driver that provides event data on process creation, network connections and file alterations. It is one of the most powerful tools available for security monitoring and gives detailed insight on what is happening on an endpoint.
Sysmon can be started from the command line, with a specific set of modules and processes to monitor but will in most cases be installed as a service … Read more.
Security Onion is a free tool to monitor for suspicious activity in network events. I find it very easy to use, especially if you integrate the MISP threat data with the Bro -Zeek- intelligence framework. Besides investigating network events, you can also use it to analyze Windows Event logs, both from a live event stream and for analyzing stored Windows events.
Winlogbeat, part of Elastic, is the shipper that we will use to send the … Read more.
I published an article on the IBM SecurityIntelligence blog on to Which Incident Response Investments Are You Prioritizing in 2020?
The post describes that improving incident response plans should be the number one priority for future investment, but there are other pressing areas to consider as well. Invest in the Future of Digital Forensics, especially in light of further inclusion of cloud, BYOD and IoT related devices. Get Ready for Changes in Network Monitoring as … Read more.
Recent versions of Sysmon support the logging of DNS queries. This is done via event ID 22 in Applications and Services Log > Microsoft > Windows > Sysmon Operational.
To enable DNS logging, you need to include the section DnsQuery in your Sysmon configuration file. For example via
Note that enabling DNS queries can be noisy. It’s best to apply filtering as proposed by the SwiftOnSecurity sysmon config file and, additionally, filter out the commonly … Read more.
I published an article on the IBM SecurityIntelligence blog on how to Improve Your Detection Capabilities With Cyber Simulation Datasets
The post describes how you can develop a strategy for testing and improving your existing detection capabilities. It starts with the traditional testing strategies as paper tests and tabletop exercises. The bulk of the article covers cyber simulation datasets, including network based data sets, host based datasets and system and application logs. The final part … Read more.
Interested in sharing your MISP usage experiences? How did you integrate MISP in your incident response workflow? Have anything to say about threat sharing in general?
There’s a BelgoMISP Meeting 0x01 for all Belgian MISP users. Submit your proposals via Github or contact us via Twitter.
I published an article on the IBM SecurityIntelligence blog on how to Measure and Improve the Maturity of Your Incident Response Team
The post describes how you can create an incident response development plan and which proven frameworks exist to assist you with this. I then provide more details on the NIST and the Global CSIRT Maturity framework. The latter, which is based on SIM3 and the ENISA three-tier approach, is then covered in more … Read more.
I published an article on the IBM SecurityIntelligence blog on How PR Teams Can Prepare for Data Breach Risks With Incident Response Planning
The post describes how you can take control of the incident response communication, how to prepare for incidents by identifying your stakeholders and preparing communication templates and which tooling is available for communication during a security incident.
Attributes in MISP have a boolean flag to_ids allowing you to indicate if an attribute should be used for detection or correlation actions. According to the MISP core format data standard, the to_ids flag represents whether the attribute is meant to be actionable. Actionable defined attributes that can be used in automated processes as a pattern for detection in Local or Network Intrusion Detection System, log analysis tools or even filtering mechanisms.
Unfortunately attributes marked … Read more.
I run a couple of honeypots which allow me to map some of the bad actors and scanners on the internet. The most popular honeypots are Dioanea, Cowrie (ssh, previously kippo) and Conpot (ICS). So far I’ve not really used this honeypot data that much for defensive purposes but a recent writeup on using ModSecurity and MISP gave me inspiration to transform this data into information that I can use as a defender.
The core … Read more.
