What devices can be used to protect IT infrastructure and business information from unauthorised access?

To protect IT infrastructure and business information from unauthorized access, organizations can use a variety of devices including firewalls, which monitor and control incoming and outgoing network traffic, and intrusion detection systems (IDS) that identify potential security breaches. Additionally, virtual private networks (VPNs) encrypt data transmitted over the internet, while secure access gateways enforce access policies. Endpoint security solutions, such as antivirus software and endpoint detection and response (EDR) systems, further safeguard devices against malware and unauthorized access.
