With the increasing reliance on technology, it is becoming more and more important to secure every aspect of online data and information. One of the best ways to secure your data is to make sure your network is protected.
What is Network Security?
Network security is the any protection of access, misuse, and hacking of files and directories in a computer network system. Some of the most common threats to a network include viruses, worms, spyware, adware and identity theft. One of the most important aspects of network security is the multiple layers of security. There is no single package or system that will offer complete protection against every threat to your network, so it is important to remember to use multiple layers of security for your network.
Many network security threats today are spread over the Internet. The most common include:
- Viruses, worms, and Trojan horses
- Spyware and adware
- Zero-day attacks, also called zero-hour attacks
- Hacker attacks
- Denial of service attacks
- Data interception and theft
- Identity theft
All of these different types of attacks can be grouped into two different groups; structured and unstructured. A structured attack is an attack by an individual who has advanced computer skills and intentionally targeted a specific group or company. An unstructured attack is an attack by an individual who does not understand who they are targeting and only use tools that can be found easily. Both types of attacks should be taken seriously because they can expose confidential information and create distrust between a company and their clients.
There are four steps to protect your network from attacks and they are:
Implement: The first step is to create and implement a network security system that provides protection and has sufficient authorization policies.
Analyze: Once the network security system is created and implemented, the system needs to be analyzed to determine if the current security system is appropriate for the network it is protecting.
Test: When an appropriate network security system is in place, it is time to conduct tests to make sure all of the securities are working and will completely protect your network against any threats.
Modify: After conducting the tests, collect the data and enhance your protections. The results will reveal where your security system is effective and where it can be improved. Hackers are always improving their attacking procedures, so it is essential to test your system frequently to remain protected and stay one step ahead of them.
By having network security in place, your company will experience business benefits. Your company is protected against business disruption, this helps keep employees productive. Network security helps your company meet mandatory regulations. Because network security helps protect your customers' data, it reduces the risk of legal action from data theft.
