Using an information security management system

It is an open secret that every business is a target for cyberattacks. Despite the fact that data breaches are growing increasingly catastrophic, many firms still believe they will never be victims. If you have strong defenses, you can prevent most attacks and prepare for a breach. People, procedures, and technology are the three ISMS pillars that help an organization to achieve adequate security compliance.

An ISMS demonstrates the organization’s approach to information security. It will help you detect and respond to threats and opportunities posed by your sensitive data and any associated assets. This safeguards your organization and business processes from security breaches and protects them from disruption if they occur.

An ISMS is a framework for establishing, monitoring, reviewing, maintaining, and enhancing an organization’s information security compliance in order to achieve business and regulatory requirements. It is designed to identify, mitigate, and manage risks effectively by conducting a risk assessment and considering the firm’s risk appetite. Analyzing information asset protection requirements and implementing appropriate controls to ensure that these information assets are protected, as needed, helps in the effective deployment of an ISMS. An ISMS consists of the policies, processes, guidelines, allocated resources, and associated activities that an organization controls together to protect its information assets.

Information is data that is organized and processed, and which has a meaning in context for the receiver. Like other key business assets, it is critical to the operation of an organization and, as such, must be adequately secured. Electronic or optical media may store digital information (such as data files), while paper-based information (such as documents) or tacit knowledge among personnel can be used to store information as well. It can be sent via courier, email, or verbal conversation, among other methods. It must be protected regardless of how it is sent.

Information is reliant on information and communications technologies and infrastructure in many enterprises. This technology is frequently a critical component of an organization, assisting in generating, processing, storing, transferring, protecting, and destroying information.

Confidentiality, availability, and integrity form the three main dimensions of information security. Implementing and managing adequate security controls as part of an ISMS that addresses a wide range of possible risks helps reduce the effect of information security events, thereby ensuring long-term organizational success and continuity.

Controls are implemented according to the risk management process and managed through an ISMS to safeguard identified information assets in order to accomplish information security. These controls include policies and processes, as well as procedures and organizational structures. In order to meet the organization’s specific information security and business objectives, controls must be established, implemented, evaluated, reviewed, and, if necessary, upgraded. A company’s business activities must be taken into consideration while implementing information security controls.

Management entails actions aimed at directing, controlling, and continuously improving an organization within proper organizational structures. Management activities are the actions, styles, or practices of organizing, managing, directing, controlling, and regulating resources. Small enterprises may have a flat management structure with just one person, whereas large corporations may have hierarchies with dozens or even hundreds of people.

From an ISMS perspective, management includes the oversight, support, and decision-making essential to meet the business objectives and regulatory requirements by ensuring the security of the organization’s information assets. Information security management is exemplified by developing and implementing necessary policies, processes, and guidelines, which are subsequently implemented across the organization.

A management system makes use of a framework to help an organization accomplish its goals. Incorporating a management system means considering the organization’s structure, policies, and planning activities, along with roles and duties.

An information security management system helps an organization to do the following:

• Meet all interested parties’ information security requirements
• Design and execute the organization’s tasks more effectively
• Realize the information security goals
• Comply with all applicable laws, regulations, and industry best practices
• Ensure systematic management of information assets

Principle of least privilege and need to know

According to the Principle of Least Privilege (POLP), a person should only be granted the privileges necessary to carry out their job. POLP also limits who has access to apps, systems, and processes to only those who are authorized. POLP is implemented in the Role-Based Access Control (RBAC) system, which guarantees that only information relevant to the user’s role is accessible and prohibits them from obtaining information that is not relevant to their role.

Following the POLP lowers the danger of an attacker compromising a low-level user account, device, or application, giving them access to vital systems or sensitive data. By using the POLP, compromises can be contained to the source location, rather than spreading throughout the entire system.

The need-to-know concept can be enforced through user access controls and permission procedures, and its goal is to ensure that only individuals who are authorized have access to the information or systems they need to perform their jobs.

According to this rule, a user should only have access to the data necessary to perform their work. Need to know implies that access is granted based on a legitimate requirement and is then revoked at the end of the project.

An ISMS reflects an organization’s attitude toward protecting data. Implementing an ISMS can be particularly important to an organization in protecting its own data as well as its clients’.

Why is an ISMS important?

An ISMS is crucial because they provide a structure for safeguarding a company’s most confidential data and assets. They aid businesses in spotting threats to their data and assets and devising strategies to counteract them.

According to recent PwC research, one in every four businesses worldwide has had a data breach that cost them between $1 and $20 million or more in the last three years. The average cost of a data breach in 2022 was $4.35 million, according to IBM and Ponemon’s 2022 research. Last year, the average breach cost $4.24 million. From $3.86 million in 2020, the average cost has increased by 12.7%.

A leading e-commerce company was fined $877 million for breaking GDPR cookie regulations, a telecom company paid $350 million to resolve a class action lawsuit over a data breach in early 2021, and a software company was penalized $60 million for misleading Australian customers about location data.

A study by the British Standards Institution (BSI) found that 51.6% of organizations with a certified ISMS reported fewer security incidents.

An ISMS helps an organization devise a plan for handling sensitive information, such as personal and confidential business information, in a systematic way. This reduces the chances of a data breach and the financial and reputational damage it can cause. An ISMS helps businesses comply with applicable laws and regulations, such as the GDPR and HIPAA, in order to avoid penalties and reputational damage.

It is necessary to address the risks connected with an organization’s information assets. All of an organization’s information assets have an associated risk, which needs to be addressed through risk management. Information security needs risk management, which incorporates risks posed by physical, human, and technological threats to all types of information stored or used by the company. This strategic choice must be seamlessly integrated, scaled, and updated to match the organization’s needs when an ISMS is designed for an organization.

The design and execution of an ISMS are influenced by a variety of factors, including the organization’s goals, security requirements, business processes, and size and structure. All stakeholders in the firm, including consumers, suppliers, business partners, shareholders, and other key third parties, must be taken into account while designing and operating an ISMS.

The importance of an ISMS cannot be overstated. An ISMS is a key facilitator of risk management initiatives in any sector. Data access and management become more challenging to govern due to public and private network interconnectivity and the sharing of information assets. Additionally, the proliferation of mobile storage devices carrying information assets has the potential to erode the effectiveness of existing controls.

Businesses that adhere to the ISMS family of standards show their ability to adopt consistent and mutually acknowledged information security principles to their clients and partners. The design and development of information systems do not always take information security requirements into account. The level of information security compliance that may be accomplished using technological approaches is restricted. It may be ineffective unless complemented by appropriate management and policy/procedures within the context of an ISMS.

It can be difficult and expensive to integrate security into a fully operational information system. An ISMS requires careful preparation and attention to detail because it entails establishing which controls are in place. As an example, in order to provide appropriate permission and access limitation to information assets or a facility, access controls need to be designed and put into place. The controls may be technological, physical, administrative, or a combination of all three, depending on the nature of the business and its information security needs.

Companies can have more confidence in the security of their information assets due to the effective deployment of an ISMS, which helps them identify and analyze risks, implement appropriate controls, and meet regulatory requirements.

In conclusion, an ISMS is valuable because it assists businesses in safeguarding private data and assets, mitigating the financial impact of data breaches, and meeting regulatory requirements. Using an ISMS enables organizations to manage their own data assets and those entrusted to them by third parties. Let’s look at the ingredients that make an ISMS implementation successful.

Key factors of an effective ISMS

Several factors contribute to the effectiveness of an ISMS implementation that helps a company to achieve its business goals. The following are the most important criteria for success:

• Documented information on information security goals, policies, procedures, and implementations that are available and in alignment with the business objectives of the organization.
• Architecture, implementation, tracking, maintenance, and enhancement of the information security framework in accordance with the organization’s culture and values.
• All levels of management, especially senior management, showing their full support and commitment. The implementation should start from the top leadership to bring the right culture throughout the ISMS processes. This is known as a top-down approach.
• Risk management and information security needs are clearly understood.
• Successful implementation of information security awareness, training, and education programs that inform all interested parties, including employees, about the defined information security obligations of the organization and motivates them to abide by them.
• An effective process for managing information security incidents.
• An effective strategy and process for ensuring business continuity.
• An adequate system for the performance measurement of an information security framework.
• Continuous improvement of management system operations by discovering and correcting non-conformities as they arise.

An ISMS boosts an organization’s likelihood of regularly achieving the important success criteria essential to safeguard its information assets.

The ISO 27000 series of standards cover all the requirements, including sector-specific ones for implementing a robust and sustainable ISMS. The organization chooses what to implement based on the business requirements.
