ZoneAlarm Firewall comes configured with optimal basic Firewall Zone settings. If you need to make changes to the basic settings, you can do these:. You can further customize High and Medium security settings for the Trusted and Public security zones to allow or to block specific types of traffic based on protocol types and port numbers. By default, ZoneAlarm software records all Firewall events in a log, and archives the log file every seven days.

By default, the Public Zone works in High security mode, and the Trusted Zone works in Medium security mode: High security mode for Public Zone lets you connect to network resources, but prevents other unauthorized network users and computers from accessing the resources on your computer and compromising your computer protection.
Unknown networks and most wireless networks, even secured wireless networks, should be in this High security Public Zone. Medium security mode for Trusted Zone protects your computer from possible attacks on Windows networking services, but lets you share resources with other computers on the network. Networks you know and trust, such as your home or business LAN and known protected wireless networks, should go in this Medium security Trusted Zone.
Blocked Zone - contains computers and networks you distrust. No traffic to or from this zone is allowed. Click Settings in the Advanced Firewall section.

The weight given to each of the three major requirements describing needs for information security—confidentiality, integrity, and availability—depends strongly on circumstances. For example, the adverse effects of a system not being available must be related in part to requirements for recovery time. A system that must be restored within an hour after disruption represents, and requires, a more demanding set of policies and controls than does a similar system that need not be restored for two to three days.
Likewise, the risk of loss of confidentiality with respect to a major product announcement will change with time. Early disclosure may jeopardize competitive advantage, but disclosure just before the intended announcement may be insignificant.

In this case the information remains the same, while the timing of its release significantly affects the risk of loss. Confidentiality is a requirement whose purpose is to keep sensitive information from being disclosed to unauthorized recipients. The most fully developed policies for confidentiality reflect the concerns of the U. Since the scope of threat is very broad in this context, the policy requires systems to be robust in the face of a wide variety of attacks. The specific DOD policies for ensuring confidentiality do not explicitly itemize the range of expected threats for which a policy must hold.
Instead, they reflect an operational approach, expressing the policy by stating the particular management controls that must be used to achieve the requirement for confidentiality. Thus they avoid listing threats, which would represent a severe risk in itself, and avoid the risk of poor security design implicit in taking a fresh approach to each new problem. The operational controls that the military has developed in support of this requirement involve automated mechanisms for handling information that is critical to national security.
Within each level and compartment, a person with an appropriate clearance must also have a "need to know" in order to gain access. These procedures are mandatory: elaborate procedures must also be followed to declassify information.

Classification policies exist in other settings, reflecting a general recognition that to protect assets it is helpful to identify and categorize them. Some commercial firms, for instance, classify information as restricted, company confidential, and unclassified Schmitt, Even if an organization has no secrets of its own, it may be obliged by law or common courtesy to preserve the privacy of information about individuals.
Medical records, for example, may require more careful protection than does most proprietary information. A hospital must thus select a suitable confidentiality policy to uphold its fiduciary responsibility with respect to patient records. In the commercial world confidentiality is customarily guarded by security mechanisms that are less stringent than those of the national security community. For example, information is assigned to an "owner" or guardian , who controls access to it. With Trojan horse attacks, for example, even legitimate and honest users of an owner mechanism can be tricked into disclosing secret data.
The commercial world has borne these vulnerabilities in exchange for the greater operational flexibility and system performance currently associated with relatively weak security. Integrity is a requirement meant to ensure that information and programs are changed only in a specified and authorized manner. It may be important to keep data consistent as in double-entry bookkeeping or to allow data to be changed only in an approved manner as in withdrawals from a bank account. It may also be necessary to specify the degree of the accuracy of data. Some policies for ensuring integrity reflect a concern for preventing fraud and are stated in terms of management controls.
For example, any task involving the potential for fraud must be divided into parts that are performed by separate people, an approach called separation of duty. A classic example is a purchasing system, which has three parts: ordering, receiving, and payment. Someone must sign off on each step, the same person cannot sign off on two steps, and the records can be changed only by fixed procedures—for example, an account is debited and a check written only for the amount of an approved and received order.
In this case, although the policy is stated operationally—that is, in terms of specific management controls—the threat model is explicitly disclosed as well. Other integrity policies reflect concerns for preventing errors and omissions, and controlling the effects of program change. Integrity policies have not been studied as carefully as confidentiality policies.

Computer measures that have been installed to guard integrity tend to be ad hoc and do not flow from the integrity models that have been proposed see Chapter 3. Availability is a requirement intended to ensure that systems work promptly and service is not denied to authorized users. From a security standpoint, it represents the ability to protect against and recover from a damaging event.
The availability of properly functioning computer systems e. Contingency planning is concerned with assessing risks and developing plans for averting or recovering from adverse events that might render a system unavailable. Traditional contingency planning to ensure availability usually includes responses only to acts of God e.
However, contingency planning must also involve providing for responses to malicious acts, not simply acts of God or accidents, and as such must include an explicit assessment of threat based on a model of a real adversary, not on a probabilistic model of nature. For example, a simple availability policy is usually stated like this: "On the average, a terminal shall be down for less than 10 minutes per month.
This policy means that the up time at each terminal, averaged over all the terminals, must be at least A security policy to ensure availability usually takes a different form, as in the following example: "No inputs to the system by any user who is not an authorized administrator shall cause the system to cease serving some other user.
