IT Security Controls for Banks
Security controls and policies are used to secure the information of a business. The safeguarding of a firm’s information is not just the responsibility of a single individual or department. Instead, it is the responsibility of a combination of individuals, departments, and the organization itself. Therefore, an organization’s top administrators who are charged with the responsibility of safeguarding the best interests of the organization should ensure that adequate and appropriate security policies are developed and implemented throughout the organization.
Financial institutions such as XYZ Credit Bank have numerous vulnerabilities that can be exploited by security threats to the detriment of the bank. No single control can protect the institution from these threats. Effective safeguarding of information can only be achieved through putting in place layers of various controls. Though the details of each control and their effectiveness in risk mitigation vary, every financial institution that has an external connective must answer that both internal and external controls exist (Smallwood, 2019). There are four IT security controls that XYZ Credit Bank can use. These are; physical security of computing devices, authorized use policy, independent testing, and rapid detection and response measures.
Physical access controls mitigate the risk caused by unauthorized access to the computing devices of an institution. This can be achieved by placing network devices, and servers in areas that can only be accessed by authorized personnel Credit Bank should meet all configuration and security requirements (Zayed, 2016).
Authorized user controls prevent the risks that arise from the use of systems by various users. This encompasses the activities that users are allowed to perform, restrictions against unsafe use of systems and malicious activities, and consequences that users will suffer due to noncompliance (Smallwood, 2019). Every internal user or contractor should be trained on how to safely use computing devices and acknowledge that they will abide by the rules and regulations that govern their safe use of the institution’s systems.
On the other hand, XYZ Credit Bank should have independent testing plans that identify control objectives. The bank should schedule testing of the existing controls to ensure that they meet those objectives. Independent testing ensures that prompt corrective action is taken in areas where weaknesses or breaches are identified (Zayed, 2016). Testing should be carried out by people who do not play a direct role in security administration.
Finally, rapid detection and response controls are meant to ensure that all system intrusions are detected in a timely manner. When an attacker gains access to the devices of a banking institution, the bank can only be saved by rapid detection and response (Zayed, 2016). The techniques that can be used to identify intrusions are automated log analysis and correlation, intrusion detection systems, and the identification of system login and usage anomalies.
