Testing your network security

Sophisticated cyber-attacks pose a serious threat for organizations today. Many businesses have had their data compromised due to insecure systems and a lack of safeguards. Data breaches can have serious financial and legal implications, as well as lasting reputational damage. 

An effective cyber security framework should incorporate preventative, detective and corrective solutions. To test the robustness of the cyber security defenses, organizations should undertake regular: 

  • Vulnerability assessments explore and identify weaknesses in cyber security controls. Identification is the first step in mitigating risk and creating a secure network. They can also help to validate the design of cyber security controls 
  • Penetration tests form the next step in reviewing the robustness of cyber security defenses. These tests exploit the identified vulnerabilities, with the aim of breaching an organization’s security perimeter – thus testing how effectively security controls are operating. 

Approaches to penetration testing 

Technology is not infallible and nor are people. An effective penetration test should assess network vulnerabilities from both the cyber standpoint and the human element. It should mirror different types of attack (Black Box, Grey Box, Social Engineering) based on the amount of information an attacker might have or their preferred technology.
