A vulnerability assessment is the process of identifying, quantifying, and prioritizing (or ranking) the vulnerabilities in a system. Examples of systems for which vulnerability assessments are performed for include, but are not limited to, nuclear power plants, information technology systems, energy supply systems, water supply systems, transportation systems, and communication systems. Vulnerability assessments can be conducted for small businesses to large regional infrastructures.

Vulnerability assessment has many things in common with risk assessment. Assessments are typically performed according to the following steps:

• Cataloging assets and capabilities (resources) in a system
• Assigning quantifiable value (or at least rank order) and importance to those resources
• Identifying the vulnerabilities or potential threats to each resource
• Mitigating or eliminating the most serious vulnerabilities for the most valuable resources

Security measures should be properly targeted, and directly related to potential impacts, threats, and existing vulnerabilities. Failure to achieve this could result in inadequate security measures and excessive or unnecessary expenditure. An appropriate threat and risk assessment promotes better targeting of security measures and facilitates better decision-making. Through the Vulnerability Assessment and Penetration Testing Services, Infysec conducts a threat and vulnerability assessment of the network infrastructure devices. Our consultants review logs, services, application processes, trust relationships, access controls, and encryption. Our consultants also conduct an in-depth assessment of servers, routers, and security devices to determine the level of threat from external attackers using vulnerability assessment tools and manual exploration. Ethically and professionally conducted security and penetration tests help organizations to understand and assess the security vulnerabilities within their systems, as well as the associated threats and risks.
