For several years, most news articles about a computer, network, or Internet-based compromise have mentioned the phrase "zero day exploit" or "zero day attack," but rarely do these articles define what this is. A zero day exploit is any attack that was previously unknown to the target or security experts in general. Many believe that the term refers to attacks that were just released into the wild or developed by hackers in the current calendar day. This is generally not the case. The "zero day" component of the term refers to the lack of prior knowledge about the attack, highlighting the idea that the victim has zero day's notice of an attack. The main feature of a zero day attack is that since it is an unknown attack, there are no specific defenses or filters for it. Thus, a wide number of targets are vulnerable to the exploit.

New in Windows Server 2012 is the Unified Remote Access (URA) role. In Windows Server 2008 R2, DirectAccess and Routing and Remote Access Service (RRAS) were two separate roles. In fact, they could not be co-located on the same server. In Windows Server 2012, DirectAccess and RRAS can be co-located, allowing for what is now legacy remote access VPN client connectivity (L2TP/IPsec, PPTP, and SSTP). This means that the Unified Remote Access provides DirectAccess, Remote Access VPN, and site-to-site VPN and can now serve as your complete remote access solution.

In actuality, there are a few other features that Windows 10 picked up first, such as PowerShell 5.0 and the latest version of Hyper-V, that are also part of Windows Server 2016. Many other heavy-hitting server-only features will be here soon.
