IT System Security Solutions Management
Security Challenges :- IT systems are prone to failure and security violations due to errors and vulnerabilities. These errors and vulnerabilities can be caused by many factors, such as rapidly changing technology, human error, poor requirement specifications, poor development processes or underestimating the threat. In addition, system modifications, new flaws and new attacks are frequently introduced, which contributes to increased vulnerabilities, failures and security violations throughout the IT system life cycle.
The industry came to the realization that it is almost impossible to guarantee an error-free, risk-free and secure IT system due to the imperfection of the opposing security mechanisms, human error or oversight, and component or equipment failure.
Completely secure IT systems do not exist; only those in which the owners may have varying degrees of confidence that security needs of a system are satisfied.
In addition, many information systems have not been designed to be secure. The security that can be achieved through technical means is limited and should be supported by appropriate configuration, process/ procedure and management.
Security Assessment and Management :- Security assurance requirements are determined by “analyzing the security requirements of the IT system, influencers, policies, business drivers and the IT system’s target environment. Influencers are any considerations that need to be addressed as they may affect the IT system assurance requirements. The influence can have any origin and may include such intangibles as politics, culture, local laws and mandated requirements".
Security is concerned with the protection of assets. “Assets” are entities upon which someone places value. Many assets are in the form of information that is stored, processed and transmitted by IT products to meet requirements laid down by owners of the information. Safeguarding assets of interest is the responsibility of the owners who place value on those assets. A risk assessment is performed to provide an in-depth look at asset sensitivity, vulnerabilities and threats to determine the residual risk and recommendations for existing and proposed safeguards. The recommendations implemented are factored into the original security requirements to revise the security assurance requirements.
The task of IT security (ITS), Solutions and management is to manage the security risk by mitigating the vulnerabilities and threats with technological and organizational security measures to achieve an IT system with acceptable assurance. ITS management has an additional task: establishing acceptable assurance and risk objectives. In this way, the stakeholders of an IT system will achieve reasonable confidence that the IT system performs in the way intended or claimed, with acceptable risk and within budget.
It is also important to note that “assurance requirements are unique to each environment due to the varied business and security requirements. The same IT system may not be suitable to other environments without modifications in line with its requirement.
To achieve comprehensive assurance, the IT system must be assessed to ensure the correct design, implementation, operation and the deliverable must provide the appropriate security functionality to counter the identified threats and weakness.
