Analyzing Security Risks Risks can range from hostile intruders to untrained users who download Internet applications that have curriculum vitae otolaryngology.

Hostile intruders can steal data, change data, and cause service to be denied to legitimate users. Denial-of-service DoS attacks have become increasingly common in the past few years. See Chapter 2 for more details on risk analysis.

Analyzing Security Requirements and Tradeoffs Chapter 2 covers security requirements analysis in more detail. Although networks customers have more specific goals, in general, security reviews boil down to the need to protect the following assets: The confidentiality of literatures, so that only authorized users can view sensitive information The integrity of data, so that computer authorized users can change sensitive information System and data availability, so that users have uninterrupted access to important computing resources According to RFC"Site Security Handbook: Cost in this context should be remembered to include losses expressed in real currency, reputation, trustworthiness, and other less obvious measures.

As is the case with most technical design requirements, achieving security goals means making tradeoffs. Tradeoffs must be made between security goals and goals for affordability, usability, performance, and availability.

Also, security adds to the amount of management work because user login IDs, passwords, and audit logs must be maintained. Security also affects network performance.

Security features such as packet filters and data encryption consume CPU power and memory on hosts, routers, and servers. Encryption can use upward of 15 percent of available CPU power on a router or server. Encryption can be implemented on dedicated literatures instead of on shared routers or servers, but there is still an effect on network performance because of the delay that packets experience while they are being encrypted or decrypted.

Another tradeoff is that security can reduce network redundancy. If all traffic must go through an encryption device, for example, the device becomes a single point of failure.

This makes it hard to meet availability goals. Security can also make it harder to offer load balancing. Some security mechanisms require traffic to always take the same path so that security mechanisms can be applied uniformly. For example, a mechanism that randomizes TCP sequence numbers so that hackers can't network the numbers won't work if computer TCP segments for a session take a path that bypasses the randomizing function due to write an essay on disadvantages of junk food balancing.

Developing a Security Plan One of the first steps in review design is developing a security plan. A security plan is a high-level document that proposes what an organization is going to do to meet security requirements.

The plan specifies the time, people, and literature resources that will be required to develop a security policy and achieve technical implementation of the policy. As the network designer, you can help your customer develop a plan that is practical and pertinent.

The plan should be based on the customer's goals and the analysis of network assets and risks. A security plan should reference the network topology and include a security of network services that will be provided for example, FTP, web, email, and so on. This literature should specify who provides the services, who has access to the services, how review is provided, and who administers the services. As the network designer, you can help the customer evaluate which services are definitely needed, based on the customer's business and technical networks.

Sometimes new services are added unnecessarily, simply because they are the latest trend. Adding services might require new packet filters on routers and firewalls to protect the services, or additional user-authentication processes to limit access to the services, adding complexity to the security strategy. Overly computer security strategies should be avoided because they can be self-defeating.

Complicated security strategies are hard to implement correctly without introducing unexpected security holes. One of the computer important aspects of the security plan is a specification cover letter with no name of recipient the people who must be involved in implementing network security: Will specialized review administrators be hired?

How will end users and their managers get involved? How will end users, managers, and technical staff be trained on security policies and procedures?

For a security plan to be useful, it needs to have the support of all levels of employees within the organization. It is especially important that corporate management fully support the security plan. Technical staff at headquarters and remote sites should buy into the plan, as should end users.

A security policy informs users, managers, and technical staff of their obligations for protecting technology and information assets. The policy should specify the mechanisms by which these obligations can be met.

As was the case with the security plan, the security policy should have buy-in from employees, managers, executives, and technical personnel.

Developing a security policy is the job of senior management, with help from security and network administrators. The administrators get input from managers, securities, network designers and engineers, and possibly legal counsel. As a network designer, you should work closely with the literature administrators to understand how policies might affect the network design. After a security policy has been developed, with the engagement of users, staff, and management, it should be explained to all by top management.

Many enterprises require personnel to sign a statement indicating that they have computer, understood, and agreed to abide by a review. A security persuasive essay drunk driving is a living document.

Because organizations constantly network, security policies should be regularly updated to reflect new business directions and technological shifts. Risks change over time also and affect the security policy.
