PERFORMANCE

Packet Loss Leads to Performance Degradation

• Packet Loss is a Real World problem • Packet loss translates to severe performance

degradation due to architectural flaw in current SSL VPN products from the market leaders

• In the US, it is not unusual to see 5~8% packet loss across the public internet

• 15-20% packet loss is typical in wireless networks (i.e., 802.11)

• In some parts of Asia 50% packet loss is typical• Worldwide average is >24% packet loss

D: Application TCP data packetA: application TCP ACK packetSD: SSL tunnel data packetSA: SSL tunnel ACK packet

This is what will be achieved.This happens when the user is working in office, i.e. connected to LAN

Comparison of NeoAccel vs. Others

Why ICAA?

• It is observed that other SSL VPN vendors simply tunnel (proxy) a complete Ethernet frame over the SSL connection to private network resulting in two TCP layers for each packet. This results in redundant layer of reliability which causes TCP over TCP meltdown problem. (Slide 4)

• Many of the applications are not designed to work over varying bandwidth lousy networks like Internet.

• There are known issues with TCP layer when working over Internet. In case of SSL VPNs when multiple application TCP connections are tunneled into a single TCP connection, the effect of TCP problems is increased exponentially. This results in frequent connection disconnects.

ICAA Benefits

• ICAA avoids the overhead of extra reliability layer induced because of tunneling application TCP traffic into SSL VPN TCP tunnel.

• ICAA reduces TCP packet loss recovery time by 30 times by avoiding tunneling of TCP connection inside another TCP connection.

• ICAA avoids the TCP layer limitations which makes TCP not suitable for remote application connections over WAN with varying bandwidth and congestion. ICAA avoids parameters like TCP window size and congestion window for each application connection. The parameters of a single SSL VPN TCP tunnel are applied to all application connections.

• ICAA does not let application connection to flow over WAN, thus avoiding TCP slow start problem, fragmentation and avoids congestion control algorithm limitations for each application connection.

• Even in 0% packet loss networks (like LAN), the number of packets are reduced by 50% straightaway.

CONFIDENTIAL

Why TSSL?

• It was observed that other SSL VPN vendors do encryption/decryption at application layer which is normally implemented at less privileged level in an OS (Slide 3, 4). This results in slow SSL processing resulting in high latency for applications connections

• The high context switching of CPU results in slower packet processing, higher latency, less throughput and low user logins/sec.

• Because SSL processing is done at user mode (less privileged mode of OS), there is an overhead between SSL module and SSL hardware accelerator cards. This results in less output from SSL hardware accelerator cards.

TSSL Benefits

• TSSL avoids the CPU context switching for both SSL VPN Gateway and Client while handling each application connection over SSL VPN resulting in high tunnel throughput.

• TSSL helps CPU spend less time doing non-VPN related tasks and helps process VPN data faster resulting in low latency and faster user logins per second.

• TSSL enables SSL VPN Gateway and SSL VPN Client to do bulk encryption resulting in better throughput.

• TSSL reduces the communication over head between SSL VPN Gateway and SSL accelerator card resulting in maximum throughput and higher SSL transactions per second.

• TSSL helps control latency added because of SSL processing for real time traffic like VOIP and video.

Why ATCE (Dynamic Compression) ?

• Other VPN solutions have a switch like functionality for compression.

• Compression benefits are truly based on the available bandwidth and the current load on the VPN gateway. Other VPNs do not consider these factors

• A ON/OFF functionality makes compression increase more load of VPN gateway even if compression of data is not required

ATCE Benefits

• Calibrates compression benefits at regular interval of times.

• Low bandwidth connections get more compression benefits compared to higher Internet bandwidth users

• Data is compressed only if data is compressible

• Optimizes the ratio of load/bandwidth

•Help•Open Help resources

General

The landing page is the System/General which displays information suchas; Version Number, Processor Information, Memory Utilization and interfaceinformation.

Interface Configuration

The interface configuration allows the administrator to change/modify ipaddress information for each network interface adapter.

To configure the SSL VPN-Plus Gateway for single arm mode select the desired interface and check the box “Configure for Single ARM mode” and click Save.Advanced configuration allows specifying Link speed & MTU size

The route menu option displays currently configured routes. To add routesto other networks select the Add button and provide the necessary information.

The DNS and Hosts Configuration sets parameter related to the SSL VPN-PlusGateway. Setting Hostname, Primary and Secondary DNS servers as well asdefining static computer hostname to IP address mappings.

NMC Administration

Ability to create multiple administrators with different access over configuration of appliance ranging from full control, restricted or read only access. 1 Full control, 8 Restricted and 8 Read only administrators can be configured.

Module 2 – SSL VPN-Plus

Module 2 focuses on creating and configuring the SSL VPN-Plus Gatewayinstance that end users will establish the tunnel with. It is possible and oftenuseful to run multiple instances or gateways on a single device. This allowsthe administrator to provide different options for user connectivity.

One example would be configuring a separate gateway for third party business partners who need tunnel connectivity. Creating a separate gateway with a singleauthentication source and other options is an effective way to plan your RemoteAccess strategy.

Gateways

The Gateways menu allows you to Add/Modify/Remove gateways and parameters. The right hand side of the screen lists the configured options.

Modify Gateway

Highlight the gateway in previous screen and select Modify. This opensa dialogue window with the General/Authentication and Advanced tabs.

Administrator can define the IP address, port, certificate and the cipher used to encrypt traffic over SSL server. A broadcast message can be optionally specified to be displayed to all end users when they get connected to VPN.

Authentication

Select the Authentication tab to change Authentication options such asEnable or Disable Authentication, prevent multiple logons with same usernameas well as prioritizing the cascaded authentication server list.Dual Authentication can be enabled wherein the end user will need to authenticate twice against two different authentication servers.

Certificate Authentication

Enable Client certificate Authentication such that end user will need to provide a certificate to be able to access private network resources. CA list contains the list of CA certificates to which the client certificate can belong.Username can also be extracted from the certificate such that end user will only be allowed to enter password for username extracted from certificate used for authentication.

Portal Customization

Portal customization allows complete redesign of how the web based access is visible to user. Look & feel can be chosen from a list of Layout & Color schemes.Layout scheme allows for logo, company name or title to be defined as per the corporation.Color scheme allows for complete change in look and feel of the portal.

Advanced

The Advance tab sets parameters for Enabling Acceleration triggered Compression,Client Auto Update Notification, Endpoint Securing Agents, Virtual Keyboard, SSO, User Logging and timeout values and enabling Forced Timeout.

Active Clients

The Active Clients shows the users who are logged into the SSL VPN-Plusand information regarding the tunnel established. The administrator candisconnect a single tunnel or all tunnels by select the appropriate button.

View Certificate

Allows the administrator to view the contents of the SSL certificate.

Module 3 – Users/Groups

The NeoAccel SSL VPN-Plus allows granular control of users and groups.You will find that most of the power of this access control is based on groupmembership. The ability to limit access methods, apply access control policies, Provide resources to access, do cleanup as well as provide the user with a customized experience is gained by the use of Group policies.

When using an external authentication source such as RADIUS or Active Directory it is not necessary to configure users directly on the gateway provided you have selected the Group Extraction option in the configuration of the external authentication servers.

Upon presenting credentials to the PHAT client or Portal, the gateway will forward that request to the authentication server and extract the users group membership and apply configured Group Policies to that user.

Authentication Servers

The SSL VPN-Plus Gateways supports the following authentication methods

•Local Database•Active Directory with/without Group Extraction•RADIUS with/without Group Extraction•LDAP with/without Group Extraction•RSA Secure ID•Client Certificates – X.509

SSL VPN-Plus utilizes a “cascading authentication” mechanism wherebythe user credentials supplied at time of login can be validated against multipleauthentication servers. Authentication servers are bound to the Gateway instanceand not the User/Group. Order of search precedence is determined by the administrator.

Menu Section

This menu selection will allow the administrator to configure Groups, Users and Auth Servers.

List of Authentication Servers

Add Auth Server - RADIUS

•Select Server type RADIUS•Provide an alias identifier•Enter the IP address of the RADIUS server•Enter the Port listening on the server•Server timeout value in seconds•Shared secret •NAS IP Address•Retry count•Enable/Disable Group Extraction based on the Class attribute in the server

Group – Private Network List

Select the Private IP network that you want to allow via the tunnel. To selectmultiple subnets hold the Control key down and select then click Add.

Group – Private Network ICAA options

The administrator can enable/disable private networks from usingICAA® technology. ICAA greatly increases traffic performance but in somecases is not compatible with certain applications/protocols.

Exclude allows the administrator to direct the client computer to exclude portions of a private network subnet traffic from being sent over VPN tunnel.

Group – Logon & Logoff Scripts

Upload certain scripts to be executed when the user gets connected to VPN or at the end of users VPN session.

Scripts could be either a batch,Java or vb based.

Group – End Point Protection

The administrator can enable certain data cleanup mechanisms for set of users belonging to a group. Either Browser cache cleanup can be enabled or blocking of cut/copy/paste canbe enabled for the duration of end users session.Secure workspace can be activated such that end user will need to work inside a secure desktop and all data will be stored in a encrypted manner on end users machine,traces of which will be deleted at the end of users VPN session.

Authorization

The authorization menu selection allows the administratorTo configure Access Control Policies, Endpoint Security scansand Security Zones

Access Control Policies - ACL

This screen is a repository of configured ACL’s. These ACL’s can be appliedto Groups and Security Zones to control user access. Much like firewall rulestake caution in applying these rules.

Add Policy – Network ACL

Add Policy – Application ACL

Blacklist / Whitelist specific set of application from being executed during the VPN Session on the basis of name or MD5 of the process.

Block VPN Access to allow execution of process , but disallow any of the traffic generated by the process to be sent over VPN tunnel.

Apply Group Access Control Policy

• Select Groups• Modify• Add ACL on

General tab and set priority

• OK

Endpoint Security Policies

Endpoint Security Policies allow the administrator to define machine specificscans to validate whether the client computer meets the security policies of the company. These security scans, host validation, are pre-user authentication.

The administrator can configure scans for the following items•File•Process•Registry•Ports•Services•WMI•Certificate Template

EPS policies are evaluated in the following order of precedence

Zone=ANDPolicy=ORRule=AND

Endpoint Security Policies

The SSL VPN-Plus comes with approximately 100 pre-configured Endpoint Security checks. The administrator can create custom check byselecting the Add button.

Modify Existing Policy

Creating Process Policy

To create a Process policy use the Windows Task Manager to locatethe running process to test for and note the executable name.In this case the test will check for Skype.exe running.

Add Policy – Skype running

Select Add Rule and enter the required information

Completed Skype EPS check

EPS - File

The administrator can check for the following attributes of Files by specifyingthe File Name and full path and File Properties.

EPS - Registry

The administrator can test for the Existence of Registry entries.

EPS – Registry cont.

The above example would check to determine if the client machine isa member of the company domain

EPS – Port Status

This allows the administrator to perform a basic port scan on theClient machine to determine whether certain ports are open/closed/listening

EPS - Service

This scan detects whether the client computer has a Windows service andwhether the service is Running or Not Running.

EPS - WMI

WMI helps in reading dynamic database of Windows. Rules created using WMIare used to check for health of firewall, anti-virus, anti-spyware.

EPS – Certificate Template

This scan helps to do a water mark check of the end users machine to identify a corporate issues machine

Security Zones

Once the administrator has configured EPS policies, upon the client computerestablishing a tunnel and prior to authentication, the results of the EPS scan willdetermine Zone membership. SSL VPN-Plus ships with 5 pre-configured Zonesand the ability to create up to 40 different security zones.

Membership of a particular zone starts at the Highest level and based upon Pass/Failof the EPS policies will traverse downward into lower zones where ACL’s may beapplied to limit resource access.

Zones allow the administrator to over-ride Group policies and control access basedupon the validation of the client computer.

In general one should never add an allow policy to a Security Zone with the exception of the Quarantine Zone.

EPS – Modify Zone

Allows the modification of EPS checks for particular Zone.

EPS – Modify Zone with ACL

This example denies RDP based on the client be placed in Semi-Trusted Zone.

EPS Upgrade

Periodic synchronization with Global EPS Upgrade server to update factory default list of policies with new releases of firewalls, anti-virus etc and security patches, servicepacks of windows.

Module 5 – Network Extension
