Network security encompasses the policies and procedures adopted to monitor and prevent unauthorized access, modification, or abuse of a computer network and associated resources. In order for network security to be effective and work effectively, it must be comprehensive enough to be able to anticipate and prevent any threats that may arise. The activities that network security monitoring covers includes the detection and reporting of network security incidents, which can include security threat information, network activity, and malicious intrusions and attacks. Activities covered by network security policies include policy management, configuration management, training, and security testing. Responsible companies also implement security measures such as intrusion detection systems, firewall, and intrusion detection and prevention equipment.
Any computer network that is intended for internal business use must be provided with an intrusion prevention system, which is computer network security technology that creates an alert in case of unauthorized access or intrusion. Such an intrusion prevention system can either be an internal network security appliance or network security gateway appliance. Such an appliance can be placed in any room or section of a business premise where access to the computers is allowed. However, for large networks, internal network appliances are not sufficient since they may not be effective against large network intrusion attacks, such as those that occur during corporate attacks.
A qualified IT specialist, on the other hand, possesses the specialized knowledge, skills, and experience needed to provide network security services. There are many benefits of hiring a specialist for network security management. A network security manager is capable of planning and deploying the most comprehensive security network policies, thereby allowing network administrators to handle a variety of tasks, including policies for security testing, handling of security incident reporting, and allocation of resources. They can also serve as a network security support provider. Thus, it is important for businesses to hire a reputable and experienced professional to ensure that their computer networks are protected at all times.
