Network Security
Network security refers to the measures taken to protect computer networks from unauthorized access, data theft, and other malicious activities. Network security is an essential component of any modern computer network, as it helps to prevent data breaches and other cyber attacks that can cause significant harm to businesses and individuals.
There are several different types of network security measures that can be implemented to protect computer networks. Some of the most common network security measures include:
Firewalls: A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. Firewalls can help to prevent unauthorized access to a network and protect against malware and other malicious activities.
Intrusion detection and prevention systems (IDPS): IDPS systems monitor network traffic for signs of suspicious activity and can help to detect and prevent cyber attacks.
Virtual private networks (VPNs): A VPN is a secure connection between two networks that allows users to access a private network securely over a public network, such as the internet. VPNs can help to protect sensitive data from interception and unauthorized access.
Authentication and access control systems: These systems are used to verify the identity of users and restrict access to sensitive information to authorized users only.
Encryption: Encryption is the process of converting data into a coded language to prevent unauthorized access. Encryption can be used to protect sensitive data, such as credit card information or personal identification numbers (PINs).
Antivirus and anti-malware software: Antivirus and anti-malware software can help to protect computer networks from viruses, trojans, and other types of malware.
Patch management: Patch management involves regularly updating software and applications to ensure that known vulnerabilities are addressed and that the network remains secure.
