Microsoft's Authenticode and Security Zones When a signed ActiveX control is downloaded, the browser detaches the signature block (which is a signed one-way hash of the control packaged together with a standard X.509 certificate issued by a certificate authority) and performs checks on the identity of the signer using Authenticode. This is a twostep process. First the certificate is examined by checking the certificate authority's identity. Then the oneway hash is checked to ensure that the same code that was signed was the code that arrived. Note that these checks say nothing at all about whether a control will or will not behave maliciously. They only check the identity of the signer and that the code has not changed since signing. Microsoft Internet Explorer 4.x implements a security zone concept meant to ease the management of security policies for signed content such as ActiveX controls and Java applets. The system organizes Web sites into four "zones of trust" (or more if you customize): Local intranet zone, Trusted sites zone, Internet zone, and Restricted sites zone. Each zone can be configured with security levels of: High (most secure), Medium (more secure), Low, or Custom. The idea is to divide Web sites into these zones and assign the zones varying levels of trust. Figure 1.7 shows a dialog box from Microsoft Internet Explorer (MSIE) that allows a user to manage Authenticode security zones.

The total cost of implementation is $105,160 Note that these costs are for the first cluster Additional clusters will cost less because implementation costs will drop Once their system administrators have been trained, there will not be any need to send them to training every time they implement a cluster Plus, after a few installs, it will probably not be necessary to employ implementation services for every cluster Per-server costs also decline as cluster sizes increase Because we are considering implementing clustering software, we must examine all the outages that it will affect Table 32 lists the outages we will consider, along with their durations and likelihoods before the clustering software is implemented Given all the statistics in Table 32, we get: RB = $75 9,360 = $702,000 The 99644 percent availability in the last box in Table 3.

2 is the level of availability that your system would attain if it had all of these outages and no others over the five-year life span of the systems It is the best possible level of availability, given these outages Additional outages would cause that level to drop even further In Table 33, we examine the same values after the clustering software has been installed We make the conservative assumption that we will recover from any outage in 5 minutes with a reliable failover In reality, failover times will vary depending on your application Some failovers will be longer than 5 minutes, whereas others will be shorter The duration of the failover will depend mostly on the time it takes to restart the application on a different host File service, shown in this example, is particularly adept at failing over quickly.

Figure 81-1: A simple scenario illustrating the uses of network management In order to motivate our study of network management, let's begin with a simple example Figure 81-1 illustrates a small network consisting of three routers, and a number of hosts and servers Even in such a simple network, there are many scenarios in which a network administrator might benefit tremendously from having appropriate network management tools:

Figure 1.7 Authenticode's signature-based trust model implements the concept of security zones in order to aid in managing mobile code. Microsoft Internet Explorer provides a dialog box that users can access to manage security zones. Though the importance of powerful policy management tools cannot be overstated, some security professionals complain that allowing a user to set security levels is not a good idea-especially if high security correlates with high level of annoyance (through implementing, for example, too many security queries).

We assume that likelihood and impact values have not changed and that only the duration of the outage is affected by the presence of clustering software..

Failure of an interface card at a host (eg, H1) or a router (eg, A) With appropriate network management tools, a network entity (eg router A) may report to the network administrator that one of its interfaces has gone down (which is certainly preferable than a phone call to the NOC from an irate user who says the network connection is down) A network administrator who actively monitors and analyzes network traffic may be able to really impress the would-be irate user by actually detecting problems in the interface ahead of time and replacing the interface card before it fails This could be done, for example, if the administrator noted an increase in checksum errors in frames being sent by the soon-to-die interface Monitoring traffic to aid in resource deployment A network administrator might monitor sourceto-destination traffic patterns and notice, for example, that by switching servers between LAN segments, the amount of traffic that crosses multiple LANs could be significantly decreased Imagine the happiness all around (especially in higher administration) when better performance is achieved with no new equipment costs Similarly, by monitoring link utilization, a network administrator might determine that a LAN segment, or the external link to the outside world is overloaded and a higher-bandwidth link should thus be provisioned (alas, at an increased cost)
