Phase 1 is resource-intensive and time-consuming. When peers agree on an IKE SA, they establish a bi-directional secure, authenticated channel for phase 2. Phase 1 authenticates peers with the ISAKMP protocol and negotiates IKE SA. IKE phase 1: Main Mode or Aggressive Mode IKE is used for the negotiation of IPSec SAs and the establishment of secure channels. This happens in the Internet Key Exchange (IKE) protocol. One secure channel for ingoing traffic and one for outgoing. IKE SA: For a bidirectional secure channel, where IPSec SAs can be negotiated. A SA is a set of security parameters encryption algorithm, encryption key length, integrity (hash) algorithm, and more. VPN) but can also be used for host-to-host as well.īefore two hosts can communicate with IPSec, they need to agree on three Security Associations (SAs). It is primarily meant for network-to-network or host-to-network communication (e.g. The entire IP packet is encapsulated inside another IP packet. Both modes can be used with AH, ESP, and AH combined with ESP. The IP packet is encryption with symmetric-key encryption. It does not provide confidentiality, as the IP packet is not encrypted.ĮSP provides confidentiality, integrity, anti-replay, and optional authentication.

AH may also prevent replay attack, by requiring a sequence number in the header. Though, NAT-T (NAT traversal) for IPSec makes it possible to use transport mode and NAT without conflict. The IP addresses in the IP header are not excluded from the hash, which is why Network Address Translation (NAT) invalidates the packet. A few IP header fields like TTL are excluded from the hash, as they will change in legitimate traffic. If the hashes do not match, the header or data must have been tampered with. If the receiver will also hash the IP header and IP payload to check if it matches the AH header hash. The IP header and IP payload are hashed together and the hash is used to build an AH header, which is appended to the original packet. IPSec consist of the following two protocols:ĪH provides authentication and integrity of the IP packet.

IPSec is integrated into the Windows Defender Firewall. It provides data confidentiality, data integrity, and data authentication between participating peers at the IP layer, which prevents impersonation, data tampering, eavesdropping, and replay attacks.

Internet Protocol Security (IPsec) is a secure network protocol implemented as an add-on in IPv4 to protect communication.

Skip to section 2, 3, and 4 if you only want to know how to set it up. However, PAW is not necessarily the favored solution by system administrators, because of the need for an extra dedicated workstation.Ĭheck out my colleague’s Nichlas Falk’s blogpost on PAW and jumphost for further details and how to deploy: īefore deploying - a common problem when testing PAW is a better solution security vice since the clean-source principal is broken with a shared server accessed by regular Tier 2 workstation. You will often log in to a jumphost over the network from your workstation and RDP to the critical server. It should only be used for management of critical servers like a DC, and daily activity as email and Internet browsing should be blocked, to prevent hackers to enter via these ways.Ī jumphost is the same as a PAW, however, the jumphost is usually a server shared amongst system administrators whereas the PAW is often a dedicated physical workstation assigned to each administrator. This guide is designed for connections between a jumphost/PAW and a DC, but it can be used for any Windows computers of Vista/Server 2008 and later.Ī physical workstation with maximal security hardening. Additionally, I will protect the RDP connection between the hosts with IPSec.

This blog post will focus on the configuration of secure RDP (Remote Desktop Protocol) access for a jumphost/PAW (Privileged Access Workstation) to a DC (Domain Controller), such that the jumphost/PAW is the only computer which the DC will accept ingoing RDP connections from.
