Check the md5 checksum of WordPress Core files against WordPress’ checksums API, using this standalone PHP file.

In various hosting environments, WordPress core-, plugin- and theme updates sometimes fail because of enabled opcode caches. Popular PHP opcode caches are OPcache, WinCache and APC.

ab, is a small benchmark utility that comes with Apache. It’s a really simple HTTP load generating tool, ideal for a simple WordPress load & speed test. How fast does your WordPress site respond? How many HTTP requests per second can your server handle? These are questions on which ab can shed some light.
How to measure WordPress’ loading time and executed database queries? During an HTTP request, WordPress executes a lot of queries on your MySQL database. Not just the database queries take time, also loading and executing PHP takes time. But how does one measure this?
Found via cyber-ir.com: This paper is the best I have ever read on how to build IOC’s with Windows Event ID’s. I highly recommend you to read it, it contains very useful information and some very interesting behavioural examples of attacker activity. If you are looking to enhance your detection in your core network this is the document!

Over the course of one week I had the opportunity to audit two hacked WordPress websites. I could quickly discover two vulnerabilities: a Cross Site Scripting, or XSS, in a premium WordPress theme
Akal, and a
SQL injection Denial-of-Service in a later to be disclosed plugin. This post describes the Akal theme XSS vulnerability.
Disk cleanup in Windows Server 2012 (R2) using DISM is one of the most popular posts here on Saotn.org. So apparently, disk space usage is an issue on Windows Server. And that made me wonder: what more ways to clean up disk space in Windows Server are there?
