Thus, ensuring the authenticity and integrity of audit logs is of vital importance, within the broad scope of auditing information security there are multiple types of audits, multiple objectives for different audits, etc.
Access controls are required to protect information assets, personal identifiable information, financial information, and proprietary business information, if audit results have already been provided, it is a good time to reassess, design and implement remediation plans, correspondingly, the organization employs good software engineering practices with regard to commercial off-the-shelf integrity mechanisms (e.g, parity checks, cyclical redundancy checks, cryptographic hashes) and uses tools to automatically monitor the integrity of the information system and the applications it hosts.
Database security concerns the use of a broad range of information security controls to protect databases (potentially including the data, the database applications or stored functions, the database systems, the database servers and the associated network links) against compromises of their confidentiality, integrity and availability, enables authorized use of a resource while preventing unauthorized use or use in an unauthorized manner by granting or denying access rights to a user, program, or process. In particular, also covered are processes for creating information systems audit and reviewing audit reports.
Cryptographic mechanisms implemented to protect information integrity include cryptographic hash functions, audit data includes all information (e.g, audit records, audit settings, and audit reports) needed to successfully audit information system activity. Not to mention, provide audit services in accordance with IS audit standards to assist your organization in protecting and controlling information systems.
Organizations shall establish procedures, and develop and maintain organization cryptographic implementations, hash functions are powerful, fast and efficient ways to hide data and to check data integrity. In comparison to, applications that function as audit tools must use cryptographic mechanisms to protect the integrity of the tools or allow cryptographic protection mechanisms to be applied to tools.
Integrity checkers are programs that detect changes to systems, applications, and data, security controls reduce the impact or probability of security threats and vulnerabilities to a level that is acceptable to your organization. Also, for any new or existing information systems used, you will evaluate the underlying technology to determine if vulnerabilities associated with process isolation pose a security risk.
An audit can help to identify gaps in processes and overall security posture as well as uncover any privacy compliance issues that will need to be addressed in order to avoid penalties, these standards require approved personnel to audit essential information, manage audit service devices and locations, integrate audit events, manage audit repositories, and process and generate audit reports, also, protect audit information and audit logging tools from unauthorized access, modification, and deletion.
