What is Vulnerability? Is cloud vulnerability scanning different from on-premises scanning?

A vulnerability is a cybersecurity term which describes the weakness in the system security design, process, implementation, or any internal control that may result in the violation of the system’s security policy. In other words, the chance for intruders (hackers) to get unauthorized access.

Yes, cloud vulnerability scanning differs from on-premise scanning. Cloud scanning focuses on virtual servers, APIs, and configurations, while on-premises scanning checks internal networks and devices for potential security gaps.

What is Vulnerability Assessment? What is the importance of Vulnerability Assessment in the company?

Vulnerability assessment is a software testing type performed to evaluate the security risks in the software system in order to reduce the probability of a threat. Here are the following points that define the importance of vulnerability assessment in a company:

• Vulnerability Assessment and Penetration Testing (VAPT) helps you to detect security exposures before attackers find them.
• You can create an inventory of network devices, including system information and purpose.
• It defines the risk level, which exists on the network.
• Establish a benefit curve and optimize security investments.
