Additional information on privacy issues and detailing the results of an informal survey of commercial security officers is provided in the two chapter appendixes. Organizations and people that use computers can describe their needs for information security and trust in systems in terms of three major requirements: These three requirements may be emphasized differently in various applications.
Job Rotation[ edit ] Job Rotation is an approach to management development where an individual is moved through a schedule of assignments designed to give him or her a breath of exposure to the entire operation.
Job rotation is also practiced to allow qualified employees to gain more insights into the processes of a company and to increase job satisfaction through job variation. Separation of Duties[ edit ] Separation of duties SoD is the concept of having more than one person required to complete a task.
It is alternatively called segregation of duties or, in the political realm, separation of powers. Without those few and far between expert level techs who can have or get the administration rights to view all aspects of any given production process it will be nearly impossible to determine the underlying cause and can lead to outrageous decisions as to what the problem must of been.
Or nobody realizing the automated software machine was running into RAM issues because every automated job was set to auto start at exactly 6: With the concept of SoD, business critical duties can be categorized into four types of functions, authorization, custody, record keeping and reconciliation.
In a perfect system, no one person should handle more than one type of function. In information systems, segregation of duties helps reduce the potential damage from the actions of one person. IS or end-user department should be organized in a way to achieve adequate separation of duties Control Mechanisms to enforce SoD There are several control mechanisms that can help to enforce the segregation of duties: Audit trails enable IT managers or Auditors to recreate the actual transaction flow from the point of origination to its existence on an updated file.
Good audit trails should be enabled to provide information on who initiated the transaction, the time of day and date of entry, the type of entry, what fields of information it contained, and what files it updated. Reconciliation of applications and an independent verification process is ultimately the responsibility of users, which can be used to increase the level of confidence that an application ran successfully.
Exception reports are handled at supervisory level, backed up by evidence noting that exceptions are handled properly and in timely fashion.
A signature of the person who prepares the report is normally required. Manual or automated system or application transaction logs should be maintained, which record all processed system commands or application transactions. Supervisory review should be performed through observation and inquiry and the trust built with directory one-level up managers.
To compensate repeated mistakes or intentional failures by following a prescribed procedure, independent reviews are recommended. Such reviews can help detect errors and irregularities but are usually expensive can raise questions as to how much can an outside independent review once a quarter know about your processes compared to people within and what level of trust can be built with those independent reviewers.
Least Privilege Need to Know [ edit ] Introduction The principle of least privilege, also known as the principle of minimal privilege or just least privilege, requires that in a particular abstraction layer of a computing environment every module such as a process, a user or a program on the basis of the layer we are considering must be able to access only such information and resources that are necessary to its legitimate purpose.
This principle is a useful security tool, but it has never been successful at enforcing high assurance security on a system. Benefits Better system stability. When code is limited in the scope of changes it can make to a system, it is easier to test its possible actions and interactions with other applications.
In practice for example, applications running with restricted rights will not have access to perform operations that could crash a machine, or adversely affect other applications running on the same system.
When code is limited in the system-wide actions it may perform, vulnerabilities in one application cannot be used to exploit the rest of the machine. In general, the fewer privileges an application requires the easier it is to deploy within a larger environment.
This usually results from the first two benefits, applications that install device drivers or require elevated security privileges typically have addition steps involved in their deployment, for example on Windows a solution with no device drivers can be run directly with no installation, while device drivers must be installed separately using the Windows installer service in order to grant the driver elevated privileges Mandatory Vacations[ edit ] Mandatory vacations of one to two weeks are used to audit and verify the work tasks and privileges of employees.
This often results in easy detection of abuse, fraud, or negligence. Job Position Sensitivity[ edit ] Security Roles and Responsibilities[ edit ] Levels of Responsibilities[ edit ] Senior management and other levels of management understand the vision of the company, the business goals, and the objectives.
Functional management, whose members understand how their individual departments work, what roles individuals play within the company, and how security affects their department directly.
Operational managers and staff. These layers are closer to the actual operations of the company. They know detailed information about the technical and procedural requirements, the systems, and how the systems are used.
The employees at these layers understand how security mechanisms integrate into systems, how to configure them, and how they affect daily productivity. Classification of Roles and their Responsibilities[ edit ] Data Owner The data owner information owner is usually a member of management, in charge of a specific business unit, and is ultimately responsible for the protection and use of a specific subset of information.
The data owner decides upon the classification of the data that he is responsible for and alters that classification if the business needs arise. This person is also responsible for ensuring that the necessary security controls are in place, ensuring that proper access rights are being used, defining security requirements per classification and backup requirements, approving any disclosure activities, and defining user access criteria.
The data owner approves access requests or may choose to delegate this function to business unit managers.
And it is the data owner who will deal with security violations pertaining to the data he is responsible for protecting.
The data owner, who obviously has enough on his plate, delegates responsibility of the day-to-day maintenance of the data protection mechanisms to the data custodian.
Data Custodian The data custodian information custodian is responsible for maintaining and protecting the data.The industry’s ability to continue generating growth, creating jobs and enabling national development and regional integration is dependent on whether it recognizes and adapts to key trends and transformational issues that will affect the industry in the short, medium and long term.
Different Levels of Identity Security. The security features governing the security of an identity can be divided into three levels of security, i.e. Level 1 for example, encoded confidential information inside an embedded chip or other means of encoding.
Technologies at this level include smart chips, magnetic strips, Radio Frequency. The framework within which an organization strives to meet its needs for information security is codified as security policy. A security policy is a concise statement, by those responsible for a system (e.g., senior management), of information values, protection responsibilities, and organizational commitment.
One can implement that policy by . Insights on governance, risk and compliance – Security Operations Centers against cybercrime | 1 Information security is changing at a rapidly accelerating rate.
Hackers are increasingly relentless, making the response to information security incidents an ever more complex. An organization or organisation is an entity comprising multiple people, such as an institution or an association, that has a collective goal and is linked to an external environment.
