The Three Main Goals of Security

Security is a critical concern in today’s digital age. With the increasing reliance on technology and the internet, individuals and organizations alike face a multitude of threats. To effectively safeguard information and systems, security professionals adhere to three main goals: Protecting, Detecting, and Responding. In this article, we’ll explore each of these goals and their significance in ensuring comprehensive security.

Preventing Unauthorized Access

The first and foremost goal of security is protecting assets from unauthorized access, ensuring that only authorized users can interact with sensitive information and systems. This goal encompasses various strategies and measures:

  • Authentication: Verifying the identity of users through methods like passwords, biometrics, or multi-factor authentication.
  • Access Control: Implementing policies that limit access to specific resources based on user roles and permissions.
  • Firewalls and Intrusion Detection Systems: Deploying technical defenses to block malicious traffic and intrusions.
  • Encryption: Securing data by encoding it so that it’s unreadable without the proper decryption key.

By focusing on protecting assets, organizations can reduce the likelihood of security breaches and unauthorized data exposure.

Identifying Security Incidents

While prevention is crucial, no security system is entirely foolproof. Therefore, the second goal of security is detecting security incidents as they occur or shortly after:

  • Intrusion Detection Systems: Monitoring network traffic and system logs to identify suspicious activities or known attack patterns.
  • Security Information and Event Management (SIEM) Systems: Centralizing log data and using analytics to detect and correlate security events.
  • Anomaly Detection: Identifying deviations from normal system behavior that could indicate a breach.

Detecting security incidents promptly allows organizations to respond quickly, potentially minimizing damage and preventing further compromise.

Mitigating and Recovering from Security Breaches

Even with robust protection and detection mechanisms in place, security incidents can still occur. Therefore, the third goal of security is responding effectively to mitigate the impact and recover:

  • Incident Response Plans: Developing strategies and procedures for addressing security incidents, including roles and responsibilities.
  • Containment: Isolating affected systems to prevent further damage or unauthorized access.
  • Eradication: Identifying and eliminating the root cause of the incident.
  • Recovery: Restoring affected systems and services to normal operation.
  • Post-Incident Analysis: Conducting a thorough review to understand what happened and how to prevent similar incidents in the future.

Responding effectively can be the difference between a minor disruption and a major data breach, making it a critical aspect of security management.


In the ever-evolving landscape of cybersecurity, the three main goals of security—protecting, detecting, and responding—serve as a comprehensive framework for safeguarding digital assets and information. By prioritizing these goals and implementing appropriate strategies and technologies, individuals and organizations can better defend against a wide range of threats. For different security companies see this.

Remember, security is an ongoing process that requires continuous assessment and adaptation to stay ahead of evolving threats. By understanding and applying these three goals, you can strengthen your security posture and reduce the risk of security breaches.
