The growing connectivity of computers through the internet, the increasing extensibility of systems, and the unbridled growth of the size and complexity of systems have made software security a bigger problem now than in the past. Furthermore, it is a business imperative to adequately protect an organization’s information assets by following a comprehensive, and structured approach to provide protection from the risks an organization might face. In an attempt to solve the security problem and comply with the mandated security regulations, security experts have developed various security assurance methods including proof of correctness, layered design, software engineering environments and penetration testing.
Penetration testing for ICS/OT Network is a comprehensive method to test the complete, integrated, operational, and trusted computing base that consists of hardware, software, and people. The process involves an active analysis of the system for any potential vulnerabilities, including poor or improper system configuration, hardware and software flaws, and operational weaknesses in the process or technical countermeasures.
Each organization should have at least some tools for assessing vulnerability. PBOsecure, experienced instrumentation control and IT professionals can provide the right solution tailored to your need by recommending the right category tool to be used for best possible performance.
The main goal of vulnerability assessment is to identify security vulnerabilities under controlled circumstances so they can be eliminated before unauthorized users exploit them. Computing system professionals use penetration testing to address problems inherent in vulnerability assessment, focusing on high-severity vulnerabilities. Penetration testing is a valued assurance assessment tool that benefits both business and its operations.
There are two areas that should be considered when determining the scope and objectives of penetration testing: testing strategies and testing types used.
Based on the amount of information available to the tester, there are three penetration-testing strategies: black box, white box and gray box.
Based on the specific objectives to be achieved, there are two penetration testing strategies which include external and internal testing.
There are three areas to test in penetration testing: the physical structure of the system, the logical structure of the system, and the response or workflow of the system. These three areas define the scope and the types of penetration testing which are network, application, and social engineering.
