Boundary protection definition
In the field of cybersecurity, boundary protection refers to technologies and sets of measures employed to secure the whole network’s perimeter by preventing unauthorized access from various external sources. The main aim of boundary protection is establishing a border around the organization’s internal networks, servers, and sensitive information from cyberattacks and potential threats.

Common boundary protection use cases
Intrusion detection and prevention systems: IDS and IPS systems work in conjunction. IDS is responsible for network traffic monitoring, like security breaches and suspicious activities, while IPS blocks and mitigates occurring threats. Both systems respond to various cyberattacks, like malware, viruses, and unauthorized network access attempts.
VPNs: Virtual private networks create encrypted connections between remote users, branch offices, and organizations’ internal networks. VPNs allow users to access internal resources while maintaining data confidentiality and privacy from various external threats.
Firewalls: Security devices and software like firewalls control incoming and outgoing network traffic according to pre-established regulations and rules. Firewalls are a fence between an organization’s internal network and the internet to prevent potential cyber threats and protect sensitive data.
Proxy servers: Proxy servers work as a custom between internal users and internet-based servers to boost security by hiding internal networks’ IP addresses. That way, proxy servers ensure anonymity that can collectively minimize potential cyber threats.
