Remote Desktop via VPN

USB Backup File Restore Improvements ,Backup files auto-restored during boot from a USB key (by naming the file to "restore.abf") will no longer be ,repeatedly restored during power-on boots. Once a restore has happened successfully, a file will be written to ,the USB drive and must be removed before the auto-restore operation will work again.  ,This prevents endless restore cycles where a USB key with a backup has been accidentally left plugged into the ,ASG and then incessantly re-applied each upon new hard-boot. ,Require TLS for certain hosts/domains in SMTP proxy ,At Mail Security >> SMTP >> Advanced >> TLS settings you can now configure lists of hosts, networks, and/or ,sender domains that should always use Transport Layer Security to communicate with the SMTP proxy. If they ,attempt an unencrypted connection with the proxy, the proxy will abort the connection. , This feature is useful for aiding compliance efforts by certain businesses or at those which require TLS as part ,of their corporate mail communications policy. ,SHA2 Site-to-Site IPSec between ASG V7 and V8 ,You can now choose SHA2 as IPSec authentication algorithm when configuring an IPSec Site-to-Site connection ,from an ASG V8 to an ASG V7 (or other IPSec servers implementing an older draft). At  Site-to-Site ,VPNIPSecPolicies, create a new policy and choose one of the entries with the "(96 bit)" suffix as IPSec ,authentication algorithm. ,WebAdmin "Terms of Use" ,Astaro WebAdmin now supports companies which require the administrator(s) to accept a legal-type disclaimer ,before entering vital areas of infrastructure for compliance or policy reasons. When enabled, users which login ,to WebAdmin must agree to the Terms of Use, and their acceptance of the agreement is logged accordingly.  ,The text is customizable via WebAdminManagementWebAdmin SettingsAdvanced.,

VPN class in C++

In our implementation, a generic controller is realized as a container class in C++, whichincludes as base classes the subcontrollers, trigger, allocator, coordinator, etc. Interfacesoffered by these subcontrollers are implemented as virtual functions that are overloaded for aspecific realization of the controllers.The design of the generic controller shown in Figure 6 has brought us the following benefits.First, it was possible for us to design and implement all three classes of controllers --VPadmission controller, VPG controllers, and VPN controller-- as a refinement of the genericcontroller class. For example, the VP admission controller in Figure 5 has two "non-trivial"controller objects --the VC resource allocator and the coordinator-- and five "trivial" controllerobjects. (Trivial controller objects can be thought of as objects which perform no action exceptthat of forwarding data to another object. They are not shown in Figure 5). The VPG controller

A qualitative analysis is presented to compare the data transfer efficiency of thetwo system topologies, assuming there are four identical crypto engines in eachsystem. The former system has 4 cryptochannels and a 32-bit bidirectional bus,whereas the optimised one has 2 C/WDMAs and 2 RDMAs as well as dual one-way64-bit data buses, hence DMA/bus transfer time in the optimised system is half ofthat in the former system under the same clock frequency. Now five data packets arerequesting the service supplied by the crypto engines. Define data transfertime ¼ 2 6 (PCI transfer time þ DMA/bus transfer time). Considering therelationship of data processing time and data transfer time, we illustrate threetypical examples in Figure 3. In Figure 3a, the data processing time is shorter thanthe data transfer time in the former system. With the system level pipelineimprovement, the PCI interface works consecutively from packet to packet in theoptimised system; however, in the former system, the PCI interface cannotcommence the next data transfer until the current data are transferred to the cryptoengine by the cryptochannel. With the dual one-way buses, the fifth data packetinput has been finished by the end of the first packet processing so that the firstcrypto engine can process the new one without halt. On the contrary, in the formersystem, the fifth data packet cannot be input until the first cryptochannel is releasedwhen the first data packet has been exported. This situation can be seen in bothFigure 3b and 3c, in which the data processing time is longer than the data transfertime. An obvious performance improvement can be found in all these three figures.Since the crypto engines are all the same, the proposed system topology improves thedata transfer efficiency significantly. Note that not only the double data bus width,but also the implementation of the dual one-way pipelined data transfer paths as wellas the independent DMA arrays make contributions to the improvement. Meanwhile, the amelioration of the data transfer efficiency drops when the data processingtime increases. Hence, the crypto engine design and the integration of theheterogeneous crypto engine arrays are critical to a high performance NSP.

There is a rich body VPN

There is a rich body of literature in social psychologythat provides a solid base for research in predictingbehaviour in a variety of domains. MIS researchers havein recent years devoted increased attention to selfe� cacy construct to better understand why people use asystem or how successful the usage might be (Venkateshand Davis 1996, Marakas et al. 1998, Compeau et al.1999, Torkzadeh et al. 1999).In order to measure dimensions of Internet selfe� cacy, we reviewed the literature on informationprocessing and self-e� cacy (Hurphreys and Revelle1984, Murphy et al. 1989, Harrison and Rainer 1992,Torkzadeh and Koufteros 1994, Compeau and Higgins1995) and generated a list of 24 items. Then ®vepractitioners and four academics were consulted toreview these items. The wording for a few items werealtered based on their input. A ®ve-point Likert-typescale was used where 1 is strongly disagree to 5 isstrongly agree. The survey was administered to MISundergraduates at a state university in the Southwestregion of the United States. Students in several sectionsof information system courses participated in the study.Participation in the study was voluntary. A total of 277(51% male, 49% female) participated in the study. Theage of the participants ranged from 17 to 57 with a meanof 24.88.The questionnaire responses were explored withseveral objectives in mindÐpuri®cation, unidimensionality, reliability, brevity and simplicity of factor structure. First, we wanted to purify the items before doingfactor analysis. The need to purify the items (i.e.eliminate `garbage items' ) that are suggested as measures

Interoperability and Mixed versus Homogenous Device Deployments

Interoperability and Mixed versus Homogenous Device Deployments

Although IPSec is a documented standard, the Request for Comments (RFCs) that document it has left room for

interpretation. In addition, Internet drafts such as IKE mode-configuration and vendor-proprietary features increase the

likelihood of interoperability challenges. For instance, there is no standard mechanism for IPSec to determine tunnel up/down

state and remote peer reachability. For these reasons, you should check with vendors of both products for interoperability

information and their participation in interoperability bake-offs. Typically a few minor changes to configurations-and

sometimes-code-are necessary to facilitate interoperability in a reliable fashion. Realize, though, that these changes may

affect the security stance of the device, so be aware of the implications of these changes. Also, in order to ensure

interoperability between products from a single vendor, it is a best practice to use the same code base across all platforms.

This scenario will decrease the likelihood of any interoperability issues with products made by the same vendor as changes

are made over time to adhere to the standards and increase interoperability with other vendors.

Issues in addition to interoperability arise in environments where different device types are deployed to build a VPN. These

issues usually arise because of interaction between the VPN and other features that complement its operation. For instance,

consider the authentication, authorization, and accounting (AAA) protocol used to manage remote users and administrators.

The granularity of support for this protocol, say Terminal Access Controller Access Control System Plus (TACACS+) or

Remote Access Dial-In User Service (RADIUS), may differ among the device types. This difference can complicate matters if

your user database does not support one of these mechanisms across all the device types deployed. The mechanisms used for

IPSec high-availability and CA support differs for some routers, firewalls, concentrators, and remote-access clients. Finally,

consider the additional resources required to train administrators on how to configure, manage, monitor, and troubleshoot

multiple device types.

used toillustrate an adaptive VPN

Source NAT. So far, in the cases we have used toillustrate an adaptive VPN, the selection of an appropriate tunnel has been based only on subnet policyrules, as it commonly is. However, an applicationbased adaptive VPN (as illustrated in Figure 6) alsoallows tunnel selection to be based on the destinationTCP port number. Unfortunately, routing tables specify routes by means of destination IP addresses and donot provide the flexibility to specify them by means ofa combination of destination IP addresses and TCP portnumbers. Let us consider again the configuration inFigure 10 and assume that now it is required thatpackets destined to the subnet 192.168.5.0/24 be sentthrough the enterprise tunnel if the destination TCPport number is 25 (i.e., e-mail) and through thenetwork tunnel if the destination TCP port number is80 (i.e., the Web). This means that the list of hostsbehind both the enterprise and network tunnelsshown in Figure 10 must be modified to include the subnet 192.168.5.0/24. The local presence IP addressesfor these two tunnels are 192.168.5.10 and192.168.1.10, respectively. But if a packet is to be sentto a specific IP address in the 192.168.5.0/24 subnet,there is no way to specify in the routing table that thegateway should be at IP address 192.168.5.10 if thepacket is to be sent to destination port 25 and at IPaddress 192.168.1.10 if the packet is to be sent toport 80.
