16 EncrypTight User Guide.
EncrypTight User Guide 17 1 EncrypT ight Overview EncrypT ight™ Pol icy and Key Manager is an innovative approach to netwo rk-wide encryption. EncrypT ight acts as a transparent over lay that inte grates easily into any existing netw ork architecture, providing encryption rules and keys to EncrypT ight encryption appli ances.
EncrypTight Overview 18 EncrypTight User Guide multiple Policy Enforcement Points (PEPs) can use common keys, while a centralized platform assumes the function of renewing k eys at pre-determined intervals.
Distributed Key Topologies EncrypTight User Guide 19 Regardless of topology , PEPs are typi cally located at the point in the ne twork where traffic is being s ent to an untrusted ne twork or coming from an untrusted net work. As an example, Figure 2 shows a hub and spoke network secured with Encryp T ight.
EncrypTight Overview 20 EncrypTight User Guide EncrypTight Element Management System The EncrypT ight Element Manageme nt System (ETEMS) is the devi ce management component of the EncrypT ight software, al lowing you to provision and manage m ultiple encryption appliances from a central location.
Distributed Key Topologies EncrypTight User Guide 21 Figure 3 Single ETKMS for multiple sites Figure 4 illustrates an EncrypTight deployment using multiple ETK MSs. W i th lar ge, compl ex networks that have hundreds of PEPs, you might want to use multiple ETK MSs.
EncrypTight Overview 22 EncrypTight User Guide T o securely transfer data between two PEPs over an untrusted network, both PEPs must share a key . One PEP uses the shared key to encrypt the data for transmission over the untru sted network, while the second PEP uses the same shared key to decrypt the data.
Security within EncrypTight EncrypTight User Guide 23 Figure 6 Layer 2 Point-to-P oint Deployment Use the Policy Manager (ETPM) and K ey Management System (ETKMS) to cr eate a Layer 3 point-to- point distributed key policy as one of several policies in a lar ger, m ore complex EncrypT ight deploym ent.
EncrypTight Overview 24 EncrypTight User Guide Secure Communications Between Devices Each node in the distributed key system, the EncrypT ight managemen t station, the ETKMSs, and the PEPs, communicate policy an d status information with other nodes.
EncrypTight User Guide 25 2 EncrypT ight Deployment Planning When deploying EncrypTight, you must plan the following: ● EncrypT ight Co mponent Connections ● Network Clock Synchroni zation ● IPv.
EncrypTight Deployment Planning 26 EncrypTight User Guide ● “Management Station Connections” on page 26 The EncrypT ight software includes ETEMS fo r appliance configuration, ETPM for policy management, and a local ETKMS. The local ETKMS depl oys k eys and policies to all of the PEPs that it manages and checks the PEPs’ stat us.
EncrypTight Component Connection s EncrypTight User Guide 27 This section describes the planning for the fol lowing connections: ● “ETPM and ETKMS on the Sam e Subnetwork” on page 27 ● “ETPM.

EncrypTight Component Connection s EncrypTight User Guide 31 Figure 1 1 Out-of-band manage ment of ETKMSs located on different Ether net networks ETKMS to PEP Connections The communications between the ETKMSs and the PEPs require a connection betw een the Ethernet ports on each ETKMS and the management port on each PEP.
EncrypTight Deployment Planning 32 EncrypTight User Guide Figure 12 In-line ETKMS to PEP communications in IP networks ETKMS to PEP Connections in Ethernet Networks If the ETKMS and the PEP are located on the same subnetwork, the ETKMS to PEP interconnection is straightforward.
Network Clock Synchronization EncrypTight User Guide 33 Network Clock Synchronization CAUTION Failure to synchroni ze the time of all EncrypTight components can result in a loss of packets or compromised security . EncrypT ight requires that the clocks on all the system ’ s components be synchronized.
EncrypTight Deployment Planning 34 EncrypTight User Guide IPv6 addresses are 128-bit addresses consisting of eight hexadecimal groups that are separated by colons, followed by an indicati on of the prefix length. Each group is a 4-digit hexadecim al number .
Network Addressing for IP Networks EncrypTight User Guide 35 Another factor to consider if you plan to use certificates is the si ze of your Encry pT ight deployment. Generating requests and installing cer tificates for a lar ge number of a ppliances can take a considerable amount of time.
EncrypTight Deployment Planning 36 EncrypTight User Guide Figure 14 Using remote IP and virtual IP addr esses to obscure the source add ress of the origin al packet ETEP PEPs operate in transparent mode by default and no IP address is assigned to the local or remote ports.
