  • It is becoming clearer every year that workstations require as much comprehensive IT security attention as servers – particularly as the popularity of mobile workstations (laptops) continues to rise. Microsoft has advanced several technologies in Windows Vista to increase workstation security. This white paper introduces eight such technologies: • User Account Control • IE7 Protected Mode • Service Hardening • Windows Resource Protection • Windows Defender • TPM and BitLocker • Network Access Protection • PatchGuard and Driver Signing (64-bit platform)...

  • As of November 8, 2010, Manually entered IP addresses are no longer supported on campus if the device is capable of using DHCP. This is true for normal dynamically assigned IP's and Static IP's. All NEW devices added to the network must be set to receive their network address via DHCP (Dynamic Host Configuration Protocol). This is the default setting for campus PC and Mac workstations and most printers. No user action is anticipated. There is no change or downtime expected for the vast majority of campus workstations or devices. We have made great efforts to put exceptions in place...

  • Taking the network scenario of Figure 1, there will be web interfaces (routers and serv- ers), BACnet/IP controllers (connected to interesting devices that are network accessible), and operator workstations that may have vulnerable OS as well as configuration files and other interesting data and resources. The following table is adapted from a Drexel report on network security [Eisenstein et al., 2003a] and lists known IT threats to a BACnet network connected to the public Internet.

  • The routed network running RIP is set up to source a default RIP advertisement to all the hosts connected to the engineering lab’s LAN. Hosts running RIP typically send all traffic destined to other IP subnets to the default router. If one of the workstations connected to this LAN has a second interface connected to another LAN segment, it advertises itself as the default router. This would cause all hosts on the engineering LAN to send traffic destined to other IP subnets to the misguided workstation.

  • In our example, we have made some simplifications. Specifically, if the DNS system worked as we just described it is not difficult to see that the root servers would receive an enormous amount of traffic. In practice this problem is solved in two ways. First, the “clients” in our example will cache all answers it receives. This means that once it has received the addresses for “se” from the root server it is able to query these servers directly for addresses within the “se” zone in the future.

  • The importance of mobile systems programming has emerged over the recent years as a new domain in software development. The design of software that runs in a mobile device requires that developers combine the rules applicable in embedded environment; memory-awareness, limited performance, security, and limited resources with features that are needed in workstation environment; modifiability, run-time extensions, and rapid application development. Programming Mobile Devices is a comprehensive, practical introduction to programming mobile systems.

  • When the need arises to protect selected user workstations from intrusion and virus epidemics, the administrator usually has to visit each computer to manually install and configure its firewall to comply with corporate security policies. Practically always, the same settings and tools are used with each workstation. In complex distributed networks this requires an administrator to spend a lot of time duplicating the same sets of operations multiple times. Moreover, the administrator must manually reapply all modifications made by each individual user.

  • The first step is to install the administration management tools. Agnitum Command Center, the main managing application is implemented as an MMC snap-in. It lets you manage Outpost Network Security Client installations over the network and control the other Outpost Network Security components (Client Configuration Editor to create and configure firewall settings, Agnitum Update Service, and Agnitum Publisher Service to publish and transfer your firewall settings to clients). Outpost Network Security does not need to be installed on a server or domain controller.

  • After the installation of Outpost Network Security is complete, you can configure the centralized automatic updates so when Outpost Network Security Client is installed on user workstations all available updates will be immediately applied so your network and each workstation always has the strongest and latest security. Centralized updates decrease network traffic. Agnitum Update Service provides automatic download and installation of each available update on all computers in your network.

  • These days, as Internet dangers and risks increase exponentially, administrators of corporate networks are obliged to pay special attention to user workstation protection. Corporate servers can be very well protected, yet their client workstations may have backdoors for outside intrusions, which can be used to steal internal data or introduce confusion. To reduce the amount of network traffic and to control Internet usage by staff, administrators are filtering web site content and blocking net advertisements.

  • Static IP addresses are typically assigned to common resources and DHCP is used for workstations. When the network was originally designed, IP subnets were assigned to dif- ferent offices and departments. However, over time and as the network grew, this subnet organization has broken down. Over the last several years IP subnets have been as- signed and reassigned without any regard to department or location. The networking staff has employed all of the standard security practices one would expect to find at most organizations of this size.

  • Although it is nearly impossible to assess all of the costs associated with virus attacks, the immediate cost of locating and removing viruses can be easily quantified. Assuming the network engineer’s yearly salary is $75,000 and he spent 75 hours searching for the in- fected workstations, the loaded labor cost of responding to this incident would have been approximately $3,750. Using Locate the network engineer was able to identify the workstations in approximately 10 minutes for a total cost of approximately $6.00.

  • The last security incident of this week occurred on Friday morning. The security adminis- trator received an alert from the intrusion detection system (IDS) in the Boston office that indicated suspicious activity originating from that office directed at the company main- frame system. The workstation IP address was available in the IDS logs. The security administrator reviewed the access logs from the mainframe and confirmed that the suspi- cious activity reported by the IDS needed to be reported to the Vice President of Informa- tion Security.

  • The security administrator logged into the Locate web console and input the IP address and dates from the IDS log. Locate looked up the historical information for the time period in question. He was immediately presented with the name, location, and phone number of the user who was using the workstation to log into the mainframe. Within seconds the security administrator had the information he needed to make his report. The Locate Solution The security administrator logged into the Locate web console and input the IP address and dates from the IDS log.

  • Changing and filling vaporisers during use. It may be necessary to change a vaporiser during use. Where possible, repeat the leak test; failure to do so is a common cause of critical incidents [10]. Some anaesthetic workstations will automatically test vaporiser integrity. It is only necessary to remove a vaporiser from a machine to refill it if the manufacturer recommends this. Vaporisers must always be kept upright. Tilting a vaporiser can result in delivery of dangerously high concentrations of vapour [11].

  • Dynamic, or "lock-and-key," access lists are one of the IOS features commonly used to tighten security on a router. They allow the network administrator to grant temporary access to a network or service when a user gives a valid ID and password. Dynamic access list statements have several advantages over static ACL entries: access can be granted for only a short time, and access can be based on the user, rather than on the IP address of the workstation.
