Designing Network Infrastructure Security. Network Infrastructure Security Overview. Network infrastructure refers to the grouping of physical hardware and logical components which are needed to provide a number of features for the network, such as connectivity, routing and switching capabilities, network security, and access control.

Active Directory (AD) is a directory service that Microsoft developed for Windows domain networks. It is included in most Windows Server operating systems as a set of.

Unlike System Monitor, which is used to monitor anything from hardware to software, Network Monitor focuses exclusively on network activity. To understand the traffic.

Network Infrastructure Security Overview Network infrastructure refers to the grouping of physical hardware and logical components which are needed to provide.

The physical infrastructure of the network refers to the physical design of the network together with the hardware components. The logical infrastructure of the network consists of all the software components required to enable connectivity between devices, and to provide network security. The network's logical infrastructure consists of software products and networking protocols and services. While Windows Server 2.

There are a number of different risks that have an impact on an organization. Some of the primary threats which you should address are listed here: Environmental threats pertain to both environmental disasters and disasters due to human intervention. Examples of environmental threats are fires, earthquakes, storms, faulty wiring, and so forth. Accidental threats relate to threats which are caused without malicious intent. Accidental risks occur when an employee accidentally deletes important files, or modifies data that should not have been changed. Deliberate threats relate to threats which are caused with malicious intent as the primary objective. Examples of deliberate threats are viruses, Trojan horses, and all other network attacks caused by hackers and intruders.

A typical security life cycle is consists of the following processes: Determining and designing the security infrastructure: The design phase of the security life cycle includes elements such as identifying the resources of the organization that needs to be secured, and then designing the security infrastructure to protect these resources. The security design team should be accountable for creating and designing security policies for the organization. Deploying and implementing security features and security policies: The security design team should also be responsible for implementing security features and security policies. Continually managing the security solution: All security software should be upgraded as necessary, and audit logs should be regularly examined. A number of common steps or processes have to be completed to design network infrastructure security: Determine the security requirements of the organization. Plan network security which should be implemented. Establish and create secure boundaries.

Implement security technologies for the network. Implement server security technologies. Implement application security technologies. Implement user security technologies. Implement an auditing strategy.

Implement a network monitoring strategy. A few methods of securing your network infrastructure are listed here: Physically secure all mission- critical network servers: A few guidelines and recommendations for implementing physical security are detailed below: All servers should be secured in a locked server room. Only those individuals that need access should be permitted to access the server room using a key or security code. You can also implement a mechanism that monitors who enters and leaves the server room. All hubs, routers and switches should be placed in a wiring closet, or in a locked cable room. You should use case locks on your servers.

You can also install case locks on other systems that can be physically accessed. You should restrict access to the floppy drive as well.

Set a BIOS password on all systems. This would prevent an unauthorized person from accessing the BIOS. You should change the operating system selection timeout interval to 0 in order for Windows to boot automatically. When you are setting up Windows, disconnect the server from the Internet. Install Windows operating systems to a NTFS partition. Ensure that you use a strong local administrator password during setup.

Using the NTFS file system and its security features. Using the Encrypting File System (EFS).

Securing network access points. Enforcing user authentication. Securing network access. Enforcing the use of strong passwords. Securing confidential network service data as it moves over the network.

Securing confidential application data as it moves over the network. Securing confidential user data as it moves over the network. Each Windows server operating system provides different features, and different security configurations which can be enabled to enhance network security and server security.

Before deciding on the operating system to utilize, you have to know which security features are required for your network design, as determined by the organization's requirements. Most organizations use a security design committee or team to determine the security needs of the organization and to deploy security policies which can meet these requirements.

The members of the network security design committee should be knowledgeable on a number of factors, including the following: The mission critical resources of the organization. The security weaknesses or vulnerabilities of the organization. The threats to which the mission critical resources of the organization is exposed.

The resources which are mainly at risk. The loss to the organization should particular resources of the organization be compromised. The level of security needed to secure the organization's resources. The security features and security policies which can be used to secure the resources of the organization. The security features and security policies which are ideal to secure particular resources. The impact of implementing security features and security policies on employees, users and administrators. The requirements for deploying identified security solutions.

Finding the Balance between Security and Usability. One of the trickiest challenges of designing network infrastructure security is to establish a balance between security and usability. The network has to be secure so that valuable network resources can be protected, but it also has to allow the sufficient extent of usability.

Networks that are too secure, or that have an exceptional high level of security can end up having low levels of usability. This typically leads to users not being able to access network resources and services. On the other hand, a network that has an exceptionally low level of network security has a somewhat higher level of vulnerability to network attacks and data corruption.

To find a balance between security and usability, the following approach is recommended: Determine the risk to which the network and its data is exposed to, and then establish the level of security needed to alleviate and protect against these risk: This would typically involve an assessment of the physical security of your network infrastructure: Assessing whether the physical building is secured. Assessing whether the network location is secured.

Determining whether access to the physical building is access controlled. Determine the impact of data being compromised. Determine which data is valuable and mission critical data: Valuable and mission critical data would typically include usernames and passwords, confidential customer information, company financial and legal information, and so forth. As mentioned previously, one of the challenges you face when designing network infrastructure security is to find a balance between security and usability.

You also need to find a balance between securing valuable or mission critical data and performance of the network. For each traffic class that should be secured, an additional layer of processing is added to the actual processing of IP packets. This makes the process of identifying valuable and mission critical data a bit more complicated. You need to find an acceptable balance between applying too much security and applying too little security. Determine which security policies need to be implemented.
