Network security Features

Why is Information Security Complex?
1) Adversaries do not have a single set ofbasic motives which drive and motivatethem
2) Distributed systems are very complex andconsist of a heterogeneous set of servers,operating systems and network protocols
3) Organisations vary so much in their goalsand strategies and can be prone to threatfrom numerous adversaries.

  • Every week a new post and file(s) will be uploaded to extend your further knowledge on how to secure a network.

    Hello,

    This is Rose writing from www.huliq.com. I visited your blog and liked your content.

    Would you be interested to send us a guest post on any of the issues related to the topics that you cover in your blog. We will publish it in our site www.huliq.com

    In return with each guest blog we will give one link in the author's byline back to your blog. We only ask that the guest post ( we prefer it be a news coverage, sources can be Google News, CNN, MSNBC, Yahoo News, BBC and others) be a unique story and not be published in your blog.

    HULIQ is indexed by Google News and Google requires that the length of the unique news is at least 5 paragraphs. We desire it to be at least 6 paragraphs if possible. And that all need to be a unique content. Once you send us a new story totally unique we will immediately publish it with you link in it, and within 15 minutes it should be indexed by Google News.

    Also, please structure author byline as follows:

    author's name:
    author's e-mail:
    author's blog url:

    Please let me know if you may have any questions about www.huliq.com.

Network Policy-Based Management

Policy-based Network Management or PBNM is the network management that is based on policy. The policy is the blend of regulations and services where these rules and regulations illustrate the conditions for resource access and management. A policy is appropriately described as a grouping of policy rules (Kenneth, 1998). Every policy rule is consists of a set of consequent set of events and conditions. The condition describes when the policy rule is can be implemented. Once, a policy rule is so started one or supplementary actions controlled by that policy rule may possibly then be executed. These events or actions are linked with either meeting or not meeting the set of conditions described in the policy rule (Mark, 1999).
The Motivation behind the Policy-based Network Management:
The mission of managing information technology resources turned out to be more and more complex as managers have to take heterogeneous systems, unlike networking applications, and scattered applications into concern. As the amount of resources to be administered raises the assignment of managing these devices and applications depends on several systems and dealer related matters. To avoid the operators from going down in too much point, the stage of pensiveness have need of to be raised in order to conceal system and network particulars. Strategies which are follow-on from the objectives of management describe the preferred performance of distributed heterogeneous networks and systems, and state means to implement this conduct. Policy offers a way of identifying and dynamically altering management approach with no coding policy addicted to the implementation. Policy based management has a lot of reimbursements of bringing steady, accurate, and understandable network systems. The profit of policy based management will cultivate as network systems turn out to be extra intricate and offer additional services like QoS and security service (Westerinen et al, 2001).
