In organizations where computers are connected to form a network, giving special attention to their security becomes important because of possible threats. Securing a network refers to the activities performed for the protection of the network and data in it. Network security provides protection by both software and hardware technologies. Effective network security practices prevent several types of threats from entering and spreading across the network.
Why is network security a necessity?
As the computer network in organizations has a lot of data placed in it, there are risks of its misuse or manipulation. If you have weak or no network security at all, you could face the following major damages:
Every business owner would agree that some critical information needs to be kept private. With a poor network security system, the business’s confidentiality can be compromised.
Having an attack on your network which compromises private customer data can ruin the reputation of companies and makes that company look incompetent in front of the general public.
Data manipulation can cause your business severe damage. It might not come to your knowledge that someone is secretly manipulating the data and causing your business harm if your network security is not in check. Data values in your business can be changed by such attacks. It might not seem as a concerning matter, but the damages can be significant especially when financial information is at stake.
There are many more potential threats that can cripple a system.
Types of Network Security Threats
The threats that compromise a network’s security can be divided into two main categories.
Resource attacks and Logic attacks
Resource attacks were more common in the 90s but have now become less popular. A resource attack forces systems to crash and makes networks unavailable for a certain period of time. Resource attacks are performed in various ways. The most common attack method is carried out by flooding the server with service requests the numbers of which are far beyond the network’s capability to handle. In some attacks, malicious software is installed in the system’s network which causes it to become vulnerable.
Logic attacks are even more severe than resource attacks. They are organized strategies exploiting weaknesses in the infrastructure. Exploitable weaknesses that make a network vulnerable include several things ranging from software vulnerabilities and weaknesses, such as backdoors, lapses, and loops in coding, to a weakness in the choice of technologies used in the network. The main aim of logic attacks is breaking into the system which, once achieved, allows the unauthorized individual to manipulate data as much as they like.
