Introduction to Information Security

Behavioral analytics, personal information, use data, credit cards and payment data, health care information, and more are all examples of data businesses create, compile, and keep from their customers. Over the last decade, the surge in organizational data collecting, combined with the growing threat of cyber assaults and data breaches, has resulted in substantial advancements in the field of Information Security Management for IT organizations.

In this blog, we will be giving an Introduction to Information Security. You can gain proper knowledge on it before making it your career. Information security management refers to the procedures and policies used by IT and commercial organizations to protect their information assets against attacks and vulnerabilities. A Chief Security Officer, IT operations manager, or a Chief Technical Officer with a team of IT operators and security analysts may be in charge of information security. Many firms create an Information Security Management System, or ISMS, as a formal, written method for managing InfoSec.

Informational Asset:

Suppose your company does not collect or identify personal information from customers. You can ask if information security management measures are necessary to protect your data. Predictably, almost all organizations have information, which they do not want to make public.

The data could be stored physically or digitally. The discipline of Information Security Management is essential for preventing illegal access or theft.

Consider whether or not your company owns and wants to protect the following types of data assets:

Business and IT companies set and publish long-term strategic and short-term tactical objectives that define their long-term aims and vision for the future. These priceless internal documents can have the secrets and information that competitors would like to see.

Information Security Management Should Protect Critical Information About Products and Services – Critical information about services, and products, including those offered by the business and IT, should be safeguarded by information security management. This comprises any data or informative products provided to clients—the source code for in-house-built applications.

If your company offers digital products, you will need data security to ensure that hackers do not steal them and resell them without your permission or knowledge.

Proprietary Knowledge/Trade Secrets – During the process of doing business, every firm creates proprietary knowledge. You can preserve this expertise in an internal knowledge base, and it is available to the IT operators and also the support workers.

The unique insights and expertise acts as a competitive advantage for your company and are also known to be trade secrets. If you don’t disclose them freely with your competitors, you should secure these trade secrets and private knowledge with information security management measures. There are more points to be discussed in the Introduction to Information Security.

Ongoing Project Documentation: Ongoing project documentation refers to the details of products or services currently being developed. If your competitors figure out what you are up to, they can try to launch a competitive product or feature sooner than expected, even benchmarking it against your new product to keep you out of the market.

Employee Data: Human resource departments collect and store information about your personnel, such as performance reports, employment history, salary, and other details. These documents may include sensitive information that a hacker may use to blackmail your staff. Before attempting to poach your personnel, a competitor organization could utilize this information to select targets.

All of these examples are in addition to confidentially submitted customer data, where a failure to safeguard the data from theft would be a breach of trust and a violation of information security regulations or legislation in some cases.

Objectives of Information Security Management:

At the organizational level, information security is centered on the CIA trinity of Confidentiality, Integrity, and Availability. For securing the confidentiality, availability, and integrity of protected information, information security controls are implemented. Each newly deployed control must be understood in promoting the CIA trinity for a protected data class by InfoSec specialists and SecOps teams. Let’s get a bit deeper into the Introduction to Information Security.

Confidentiality: When it comes to InfoSec, the terms confidentiality and privacy are interchangeable. Maintaining information confidentiality entails ensuring that only authorized individuals have access to or edit the data. Information security management teams can classify or categorize data depending on compromised data’s perceived risk and potential impact. For higher-risk data, further privacy protections can be introduced.

Integrity: Data integrity is addressed by information security management by providing controls that ensure the consistency and correctness of stored data throughout its life cycle. To be considered secure, an IT organization must verify that data is correctly stored and cannot be edited or deleted without the required authorization. To help ensure data integrity, measures like version control, user access controls, and check-sums can be applied.

Availability: Data availability is addressed by information security management by implementing processes and procedures. This can ensure the important information is available to authorized users when they need it. Hardware maintenance and repairs, patching and upgrades, and implementing incident response and disaster recovery processes are all everyday activities to prevent data loss in the event of a cyber attack.

Information security management is more than a requirement for some businesses to protect critical internal documents and consumer data. Information security management may be a regulatory obligation depending on your industry vertical to protect sensitive information collected from clients.

Information Security Policy:

An information security policy is a document that an organization creates based on its unique demands and requirements. It aids in determining what data to safeguard and how to protect it. These policies assist a business in making purchasing decisions for cybersecurity tools, and it also establishes expectations for employee behavior and responsibilities.

The following items should be included in an organization’s information security policy:

  • It should state the aim and goals of the information security program.
  • To ensure that everyone understands the paper, it must clarify the main terminology.
  • It has to have a password policy.
  • It should establish who has access to which information.
  • It must specify the employee’s roles and responsibilities in terms of data security.
