Network Security

In computing, network security, also known as cybersecurity or IT security, is the practice of protecting computer networks and user data from unauthorized access or damage. Network security includes the prevention of unauthorized access, use, disclosure, interception, or destruction of data.

​

Data can be stolen or destroyed in a number of ways, including:

​

• Accessing information without authorization

• Intercepting information in transit

• Tampering with or destroying data

• Introducing malware into systems

• There are a number of ways to protect against these threats, including:

• Using firewalls to restrict access to networks

• Encrypting data so that it cannot be read without authorization

• Using passwords and other authentication methods to control access to systems

• Monitoring networks for unusual activity

• Scanning systems for malware and removing any that is found

• Restricting user permissions to only the files and folders they need to access

 

Network security is essential for businesses, governments, and individuals alike. By protecting computer networks and user data, we can help ensure that our systems are safe and secure.
