Security is the most important aspect of any network, and with the rise of network threats, the importance of network security in the enterprise has grown significantly. However, there are three factors that can complicate the security of a network, and if not taken into consideration, these factors can cause huge damage to the network in the long run.
Network security is the first factor that should be looked at when designing a network. The network security should include the physical and logical network components of the system, the network access devices (the switches, routers, firewalls), the network security appliances (such as the antivirus, etc.) and the data center devices that manage the hardware of the whole network.
In addition, the network administrator also needs to consider the security needs of the devices such as the network access, data-center, switches, and routers. The access control lists (ACLs) are important components of the network security, because ACLs restrict the access to resources within the network. If the security provider allows the network administrator to deploy more than one device that accesses the same resource, it will create a loophole for the attack. The network administrator needs to be able to understand the hardware and software in the device, and to enforce the set of policies that apply to all the devices.
Access control lists are used to control the access to hardware resources in a network. These lists usually include a list of all the users that are allowed to use the resources. In order to protect the data on the devices, there are some default rules that a firewall also needs to implement. However, it is a good idea to implement separate rules to ensure that the security of the network is not compromised in any way.
Network security is a very complex subject, and it can sometimes be confusing to the network administrator about the various types of rules and controls that should be implemented. It is best to use a framework that is established by the industry standards for network security. These frameworks have specific standards to help the administrator to define the types of network security and the resources that should be secured.
A standard security framework has a number of components. The first one is the definition of security policies. The security policies can be as complex as the network security needs, but they should follow a predetermined set of rules. In addition, the policy and rules are enforced by an ACL.
An ACL is a simple classification of resources. There are two basic classifications of resources, network resources and storage resources. The definition of a policy is the criteria that a user applies to classify the resources.
In a domain environment, the application security applies to a single application and its users, while the data security applies to a group of resources. In a hybrid environment, the security policies are used to restrict the access to the resources, while the security and confidentiality policies are used to restrict the access to the network.
The process of implementing the network security must be systematic. There should be a standardized set of rules for implementing the security controls of the network, so that the administrators can implement the policies in a systematic manner. The only exception is that when a particular access control system is implemented, it is included in the standard security framework, which means that there is no need to re-invent the wheel.
The same applies to the application security and the firewall security. When the firewall is implemented, it is included in the standard security framework, so that it does not have to be re-invented. This means that a firewall implementation is easy, because it follows the logic of the standard security framework.
However, when a network security is implemented, the hardware resources of the network are hard to manage. Therefore, the security management must be done properly. It is important to consider the hardware inventory, since the security management is done through the inventory.
One thing that must be considered before implementing the network security is that the implementation of the network security must be done in a systematic manner. The standard frameworks of network security should be followed and all devices that are connected to the network should have similar and defined security policies.
