Geolocation can be automatically built into the Graylog platform by using the "GeoIP Resolver" plugin with a MaxMind database. However, you can further improve your ability to extract meaningful and useful data by leveraging the functionality of pipelines and lookup tables. In fact, these powerful features allow you to do much more than the basic plugin.
Log management software operates on the basis of receiving, storing, and analyzing different types of log format files. There are several of these standardized log formats that are most commonly generated by a wide assortment of different devices and systems. As such, it is important to understand how they operate and differ from one another so that you can use them the right way, as well as avoid some common mistakes.
Gathering logs that contain IP addresses are quite common across your infrastructure. Your firewalls, web servers, wireless infrastructure and endpoints can contain IP addresses outside your organization. Having additional data on those logs that gives you the Geolocation of the IP address helps in your investigations and understanding of your traffic patterns. For Example, if you can see logs on a World Map, you know if you are communicating to a country you don’t normally talk to.
Cloud computing has changed the way we think about software, and opened up many new possibilities in both business and software development. Log management tools have also been affected by this, which begs the question – what are the pros and cons of cloud log management when compared to on-premises solutions? There are several key things you should consider before opting for either one, so here is a brief overview of the most important aspects that will help you make an informed decision.
AWS is a popular destination for IaaS that offers quickly saleable resources to meet even the largest customer demands. Cloud scalability like this can generate a large amount of logs you need to monitor to keep up with your cybersecurity goals. Getting those logs into a SIEM or centralized log management platform such as Graylog is key to have proactive monitoring and alerting.
Logs are a wealth of information containing meta-data from IP addresses, User Names, and error codes. While this is all extremely helpful, the task of understanding all this can seem overwhelming at times to an untrained eye. Other times, corporations might have additional resources they would like to enrich their logs with, i.e., adding a department name to a log message that depends on the username in the log.
Any system connected to the Internet is vulnerable to malicious attacks and breaches. If it’s online, there’s someone out there trying to break into it and do something bad with it (usually stealing data). Plain and simple. To protect your most valuable assets, you need bulletproof security measures, a skilled SecOps team, robust investigation tools, and reliable prevention/mitigation strategies.
Behavior analytics is a powerful tool in intrusion detection and prevention, using insights from typical user behavior to detect suspicious activity. What role does log monitoring have in this process and how does it work together with behavioral analytics?
Cloudtrail logs provide excellent insight into how your AWS account is being used. They record all activity by the web console, SDKs, and APIs. With help from the AWS plugin, getting this information into Graylog is easier than ever. In this blog post you'll set up the required AWS resources, configure the Graylog input, and do some basic searches to explore its capabilities.
The Internet of Things (IoT) revolution has set the beginning of a new age of data transfer. Each day, a massive number of new devices get added to all kinds of network infrastructures, transferring gargantuan amounts of data back and forth. In the next decade, we expect the number of IoTs to grow to a staggering 80 billion connected devices – practically outnumbering the human population tenfold.
