How Secure Is Your Network?
Network security involves the measures and practices employed to protect the integrity, confidentiality, and availability of data and resources as they are transmitted or accessed over a network. This includes safeguarding against unauthorized access, attacks, and data breaches.
Key components of network security.
Firewalls: These act as barriers between a trusted internal network and untrusted external networks, filtering incoming and outgoing traffic based on predefined security rules.
Intrusion Detection and Prevention Systems (IDPS): These systems monitor network traffic for suspicious activity and can take action to prevent potential threats.
Encryption: This technique involves converting data into a coded format to prevent unauthorized access during transmission or storage.
Authentication: Policies and mechanisms that ensure only authorized users can access specific network resources, often involving authentication methods such as passwords, biometrics, or multi-factor authentication.
Antivirus and Anti-Malware: Software designed to detect, prevent, and remove malicious software that could harm the network.
Virtual Private Networks (VPNs): These create a secure, encrypted connection over a less secure network, such as the internet, to protect data while it's transmitted.
Security Information and Event Management (SIEM): Systems that aggregate and analyze security data from across the network to detect and respond to potential threats in real time.
