It’s been weeks since Apple released its new operating systems, iOS 10 and mac OS Sierra. The new updates brought security patches, features and upgrades. Has finally arrived on desktops, and an exciting universal clipboard allows you to select photos from an iPhone device and paste them directly on the desktop. However, with these changes, Apple has decided to leave old loose ends which could affect the security of its products. One of the changes is Apple’s departure from the PPTP encryption protocol in its built-in VPN. The reason for such a step is because of a found in this security protocol. Cisco AnyConnect Client for Mac incompatible with MacOS High Sierra I'm trying to connect with a DevNet Lab sandbox and have to download the Cisco AnyConnect Client in order to connect with the sandbox VPN, but when I try to download the client and install it i get a warning saying the version of the client i'm downloading is incompatible with. Due to changes in how Apple treats systems extensions in macOS High Sierra (10.13). WHO IS AFFECTED? Users attempting to upgrade to Cisco AnyConnect 4.5 on macOS High Sierra. Earlier versions of macOS are not affected. WHAT DO YOU NEED TO DO? Affected users will need to take an extra step to upgrade to Cisco AnyConnect 4.5. Apple has publicly announced the and encouraged the use of other security protocols, such as L2TP/IPsec, IKEv2/IPsec, Cisco IPsec, and SSL VPN.

PPTP (Point-To-Point Tunneling protocol) – which is considered weak encryption protocol – is also perceived as the fast communication protocol that offers better speed than other protocols. It leaves many PPTP VPN users frustrated as they are hand-tied to using third-party client applications in order to use PPTP VPN connection. ![]() ![]() Microsoft also mentioned and advised its users to use alternative protocols in a: “iOS 10 no longer supports the PPTP VPN protocol. If you have deployed any custom profiles in Intune that use the PPTP protocol, iOS 10 will remove the PPTP connections from any VPN profiles when a user upgrades their device. Intune supports alternatives to PPTP from the IT Admin console.” Apple has always been taken the security a top priority, which could be seen by the recent question and answers session by the company’s CEO, Tim Cook. There, he described encryption as “one of the things that make the public safe.” He further said: “We feel we have a responsibility to protect our customers.” “We believe the only way to protect both your privacy and safety from a cyber attack is to encrypt. We throw all of ourselves into this and are very much standing on principle in this.” While departing from a PPTP connection may seem a frustration for some and a cumbersome process for organizations to update their protocols, it is also a step forward to ensure the security of those who are using and iOS devices. Understanding the said protocols L2TP/IPsec L2TP (Layer 2 Tunneling Protocol) is a tunneling protocol used in VPN connection. It does not have its own encryption algorithm but relies on the encryption suite of IPsec, which authenticates and encrypts each IP packet of a communication taking place. This protocol offers a balance of speed and security as compared to PPTP. However, L2TP is not compatible with NAT, port-forwarding becomes a necessity in some cases, and if the IP of the IPsec server changes, all clients needs to be informed of the change. IKEv2/IPsec (VPN Reconnect) IKEv2 (Internet Key Exchange version 2) is a tunneling protocol that uses IPsec encryption protocol over UDP port 500. Jointly developed by Microsoft and Cisco, also dubbed as “VPN reconnect,” IKEv2 provides resilience to the VPN connection. When the VPN client moves from one wireless hotspot to other, it automatically disconnects all internet activities when a VPN connection is lost and re-establishes the connection upon successful connectivity. Mobile users specifically can benefit from such a protocol. However, it is not supported on many platforms as it is fairly new to VPN services.
