Information Security Management System: Introduction to ISO 27001

Current scenario: Today’s organizations are highly dependent on information systems to manage their business and deliver products/services. They rely on IT for development, production and deployment across various internal applications. The application includes financial databases, employee time bookings, provision of helpdesk and other services, provision of remote customer/employee access, remote access to customer systems, interactions with the outside world via email, internet, use of third party and outsourced suppliers.

business needs:Information security is required as part of the contract between customer and customer. Marketing wants a competitive advantage and can create trust with the customer. Executive management wants to know the status of IT infrastructure failures or information breaches or information incidents within the organization. Legal requirements such as data protection law, copyright law, design and patent regulation and regulatory requirements of an organization should be met and well protected. Protecting information and information systems to meet business and regulatory requirements by providing and demonstrating a secure environment for customers, managing security between projects of competing customers, and preventing leakage of confidential information are the top challenges for information systems.

Information definition: Information is an asset that, like other important business assets, is of value to an organization and therefore needs to be adequately protected. Whatever form the information takes, or how it is shared or stored, should always be adequately protected.

information forms: Information can be stored electronically. It can be transmitted over the network. It can be shown on videos and can be verbal.

Information Threats:Cyber ​​criminals, hackers, malware, trojans, phishes and spammers are major threats to our information system. The study found that the majority of those who committed the sabotage were IT workers who, among other things, argued with colleagues, were paranoid and upset, were late for work, and exhibited poor job performance overall. 86% of cybercriminals were in technical positions and 90% had administrators or privileged access to corporate systems. Most committed the crimes after their employment ended, but 41% sabotaged systems while still employed at the company. Natural disasters such as storms, tornadoes and floods can cause great damage to our information system.

Information security incidents: Information security incidents can result in disruption of organizational routines and processes, reduction in shareholder value, loss of privacy, loss of competitive advantage, reputational damage resulting in brand debasement, loss of confidence in IT, spending on information security assets for corrupted, stolen or corrupted data or Losses in incidents, reduced profitability, injuries or deaths when safety-critical systems fail.

Some basic questions:

• Do we have IT security guidelines?

• Have we ever analyzed threats/risks to our IT operations and infrastructure?

• Are we prepared for natural disasters such as floods, earthquakes, etc.?

• Are all of our assets secured?

• Are we confident that our IT infrastructure/network is secure?

• Are our business data safe?

• Is the IP telephony network secure?

• Do we configure or maintain application security features?

• Do we have a separate network environment for application development, testing, and production servers?

• Are physical security breakout office coordinators trained?

• Do we have control over software/information distribution?

Introduction to ISO 27001:In business, the right information from the authorized person at the right time can mean the difference between profit and loss, success and failure.

There are three aspects of information security:

confidentiality: Protecting information from unauthorized disclosure, perhaps to a competitor or to the press.

Integrity: Protecting information from unauthorized modification and ensuring information such as price lists is accurate and complete

Availability: Ensuring information is available when you need it. Ensuring the confidentiality, integrity, and availability of information is essential to maintaining competitive advantage, cash flow, profitability, regulatory compliance, and commercial image and branding.

Information Security Management System (ISMS): This is the part of the overall management system based on a business risk approach to establish, implement, operate, monitor, review, maintain and improve information security. The management system includes organizational structure, policies, planning activities, responsibilities, practices, procedures, processes and resources.

About ISO 27001:- A leading international standard for information security management. More than 12,000 organizations worldwide have been certified according to this standard. Its purpose is to protect the confidentiality, integrity and availability of information. Technical security controls such as anti-virus and firewalls are not typically assessed in ISO/IEC 27001 certification audits: it essentially assumes that the organization has implemented all necessary information security controls. It focuses not only on information technology but also on other important assets of the organization. It focuses on all business processes and company values. Information may or may not relate to information technology and may or may not be in digital form. It is first published as a Code of Practice by the Department for Trade and Industry (DTI) in the UK, known as BS 7799. ISO 27001 consists of 2 parts ISO/IEC 27002 and ISO/IEC 27001

ISO/IEC 27002:2005: It is a code of practice for information security management. It offers best practice guidance. It can be used as needed in your business. It is not used for certification.

ISO/IEC 27001: 2005:It serves as the basis for certification. It’s something management program + risk management. It has 11 security domains, 39 security objectives and 133 controls.

ISO/IEC 27001: The standard contains the following main sections:

  • risk assessment
  • security policy
  • asset management
  • personnel security
  • Physical and Environmental Security
  • Communication and operations management
  • access control
  • Acquisition, development and maintenance of information systems
  • Management of information security incidents
  • Business Continuity Management
  • attention

Benefits of Information Security Management Systems (ISMS):Competitive advantages: Business partners and customers respond positively to trustworthy companies. An ISMS demonstrates maturity and trustworthiness. Some companies will only work with those who have ISMS in place. The implementation of ISMS can lead to efficiency gains in operations and thus lower business costs. Companies with ISMS may also be able to compete on pricing.

Reasons for ISO 27001: There are obvious reasons to implement an Information Security Management System (ISO 27001). The ISO 27001 standard meets legal or regulatory requirements. Information resources are very important and valuable for any organization. The trust of shareholders, business partners and customers should be developed in the organization’s information technology in order to achieve business advantages. ISO 27001 certification demonstrates that information assets are well managed, taking into account the security, confidentiality and availability aspects of information assets.

Introduce ISMS:Information security – management challenge or technical problem? Information security needs to be viewed as a management and business challenge, not simply a technical issue that needs to be handed over to experts. To keep your business safe, you need to understand both the problems and the solutions. In setting up the ISMS management, 80% play the role and 20% the responsibility of the technology system.

beginning:- Before you start implementing ISMS, you need to get management/stakeholder approval. You need to see if you’re trying to do this for the whole organization or just a portion. You need to assemble a team of stakeholders and qualified professionals. Optionally, you can add consultants with implementation experience to the team.

ISMS (ISO 27001) certification: An independent, third-party verification of the organization’s information security based on ISO 27001:2005 standards.

Pre-Certification: Level 1 – Documentation Audit

Phase 2 – implementation audit

Post-certification: Continuous monitoring for 2 years. 3rd year reassessment/recertification

Conclusion: Before implementing the information security controls management system, the organization has various security controls over the information system. These security controls tend to be somewhat disorganized and disjointed. Information, which is a very critical asset for any business, needs to be well protected from data leaks or hacking attacks. ISO/IEC 27001 is an information security management system (ISMS) standard that ensures that well-managed processes are adapted for information security. The implementation of ISMS leads to efficiency gains in operations, resulting in reduced business costs.
