IT Security Management – A Necessity in the 21st-Century Workplace

June 1, 2023

In today’s digital age, IT Security Management has become crucial to running any organization. With the increase in cyber threats and data breaches, protecting an organization’s information systems from unauthorized access, disclosure, disruption, modification, or destruction is essential. It involves developing, implementing, and maintaining policies and procedures that aim to safeguard an organization’s information assets.

Policies and Procedures

IT Security Management (ITSM for short) aims to ensure the availability, integrity, and confidentiality of an organization’s data, information, and IT services. The first aspect of ITSM involves the development of policies and procedures. This includes creating a set of guidelines that outline how an organization’s information systems should be used, how data should be stored and transmitted, and who should have access to it. These policies and procedures are designed to ensure that all employees are aware of their responsibilities and follow best practices regarding IT security.


Once policies and procedures have been developed, the next step is implementation, which involves deploying security measures and controls aligned with the policies and procedures. Implementation requires training employees to use these security measures and report suspicious activity.

Maintenance and Improvements

The final aspect of ITSM is maintenance. This involves continuously monitoring and assessing the effectiveness of security measures and controls. Regular audits and risk assessments are performed to identify vulnerabilities and develop risk mitigation strategies. Updates and patches are regularly applied to the organization’s software and hardware.

The 5 Pillars of IT Security Management

The proper management of IT security is supported by 5 pillars designed to meet the safety and privacy standards associated with managing, storing, and distributing data.

  1. Confidentiality – Confining the access of data to licensed individuals who are instructed not to disclose it to others. While breaches may occur due to mishandling or hacking attempts, confidentiality facilitates proper data classification, encryption, access, and disposal of data.
  2. Integrity – This involves keeping the information intact, complete, and accurate, as well as keeping IT systems operational. There are several measures to maintain data integrity including a checksum (a mathematical formula applied to a block of data to ensure the data is intact after usage and during transfer), version control, and access control.
  3. Availability – One of the sole objectives of ITSM is to ensure that the systems responsible for transferring, storing, and processing information are accessible by authorized personnel as and when they require it. Measures to maintain the availability of data include redundant systems’ disk arrays and clustered machines.
  4. Authenticity – Putting in place a hierarchical system to ensure that the user is who he claims to be. There are various ways to do so – including biometrics, smart cards, and digital certificates. These ensure the authenticity of transactions, communication, and documents.
  5. Non-Repudiation – Simply put, non-repudiation is an assurance that one cannot deny the validity of something. It is a method to guarantee that the sender of a message cannot later deny having sent the message, and the recipient cannot deny having received it.

Conclusion: IT Security Management is an Essential Business Strategy

IT Security Management has become essential to any organization’s overall risk management strategy. By implementing robust ITSM measures, organizations can protect their sensitive information and ensure the continuity of their operations.

IT Security Management protects an organization’s information systems from unauthorized access, including preventing hackers and cybercriminals from accessing sensitive information such as financial data, trade secrets, and customer information. Another critical aspect of IT Security Management is controlling data use, disclosure, disruption, modification, or destruction. This involves implementing encryption, access controls, and data backup and recovery procedures. By implementing these measures, organizations can protect their data from unauthorized access and quickly recover from data loss or corruption.

IT Security Management ensures employees have appropriate access to information and systems based on their roles and responsibilities. For easy-to-deploy, easy-to-use security management software that optimizes risk reduction, check out SecurityShield.
