Hey, there. This is part six of the Elastic SIEM for home and small business blog series. If you haven’t read the first, second, and third blogs, you may want to before going any further. In the Getting started blog, we created our Elasticsearch Service deployment and started collecting data from one of our computers using Winlogbeat. In the Securing cluster access blog, we secured access to our cluster by restricting privileges for users and Beats.
Editor’s note: CVE-2020-0601, unsurprisingly, has created a great deal of interest and concern. There is so much going on that we could not adequately provide a full accounting in a single blog post! This post focuses on detection of the vulnerability based on network logs, specifically Zeek as well as Endpoint. If you are collecting vulnerability scan data and need to keep an eye on your inventory of systems that are at risk, then check out Anthony Perez’s blog.
AWS S3 Server Access logs provide detailed records for requests made to S3 buckets. They’re useful for many applications. For example, access log information can be useful in security and access audits. It can also help generate customer insights and better understand your Amazon S3 bill. Coralogix makes it easy to integrate with your S3 server access logs via a Lambda function.
AWS VPC Flow Logs record details about the traffic passing through your application, including requests that were allowed or denied according to your ACL (access control list) rules. It also has information about the IP addresses, and ports for each request, the number of packets, bytes sent, and timestamps for each request. This information brings deep visibility and the ability to improve your security posture over time.

Security logs can be kept by the system itself or various applications that aim to provide security or enhance the efficiency of already installed security software. Read our article to learn more about them and for how long you should keep them.
When it comes to having visibility and detecting threats on macOS, one of the best sources of information for file system events, process events, and network events is the kernel. MacOS kernel extensions provide the ability to receive data about these events in real time with great detail. This is good for providing quick visibility into detecting anomalies and identifying possible threats.
Recently, Security Boulevard published an article I wrote about the role technology plays in the modern security operations center (SOC). It’s a topic near to my heart, since I began working in SOCs back when we were known as “computer incident response teams” (CIRT). Over the years, I’ve seen a lot of outstanding technologies hit the market that have contributed greatly to improving security teams’ ability to identify, investigate and respond to threats.
