Perimeter Security
Perimeter security is a cybersecurity strategy focused on protecting the boundaries of a network or system from external threats. It involves implementing controls like firewalls, intrusion detection systems, and access controls at the network edge to prevent unauthorized access. This approach aims to create a secure barrier between trusted internal resources and untrusted external environments.
Developers should understand perimeter security when designing or maintaining systems that face the internet, such as web applications, APIs, or cloud infrastructure, to mitigate risks like data breaches and attacks. It's crucial for compliance with regulations like GDPR or HIPAA and for protecting sensitive data in industries like finance or healthcare. Learning this helps in implementing defense-in-depth strategies alongside other security layers.
