How to allow a normal user to start, stop, and pauze/continue a Windows service

By default, starting and stopping Windows services are tasks that can only be performed by administrators. There are cases where you want regular users to be able to start or stop services. This can be easily accomplished using the subinacl.exe command-line tool.

This is the subinacl.exe syntax of how you can allow a normal user to start, stop, and pauze/continue a service.

How to list hidden shares remotely

When sharing Windows folders on the network, it is possible to hide the shared folder from the list of shares. This can be done by adding a $-sign to the end of a share name.
It is important to mention that this does not really hide such shares from the network. If you ask a Windows machines for a list of its shares, then it reports all shares, including those with a $-sign. It are then the clients who filter out all shares that end in a dollar-sign.

So how can you get a list of all the hidden shares on a server?

Remove whitelisted events from Splunk search results

Splunk is a great tool to monitor and review many different kinds of log files. In some cases it can occur that you want to be alerted of specific types of events, but only for occurrences of the events that are not defined in an exceptions whitelist. For example: you may want to be alerted of all logons to your server by users who are not IT employees. While it is possible to enumerate all exceptions in the search query, this article shows how this can be done by storing all exceptions in a CSV-file.

Scan for FREAK using nmap

Not everyone is vulnerable to the potential attack vector that researchers from INRIA, a French research institute, and Microsoft disclosed recently. In order to be vulnerable, the computer or server must support a class of deliberately weak export cipher suites. Support for these weak algorithms has remained in many implementations, however they are typically disabled by default. Nevertheless, the researchers discovered that several implementations incorrectly allow the message sequence of export ciphersuites to be used even if a non-export ciphersuite was nogotiated.
