What Is Information Security Rutherford

What is Information Security?

Information security, or Infosec for short, is the set of practices and tools designed to protect data from unauthorised access, modification, destruction or inspection. Often, the terms infosec and cyber security are used interchangeably, but infosec is exclusive to the processes applied for data security and falls under the general umbrella of cyber security.

What Is the Purpose of Information Security?

For many businesses, the information they have collected and stored is an asset that adds value. For example, the personal details of clients and customers. As there is increasing dependence on IT, sensitive data is becoming more susceptible to security threats. Information security will help mitigate the risks if such a threat takes places. Protecting both the physical and electronic environments of data ensures that a company’s reputation and financial well-being are protected. Cyber-attacks can be time consuming and costly to deal with, despite this, information security is usually put on the back burner and the importance of it is only acknowledged after such an attack.


What Are the Three Principles of Information Security?

The three principles of information security are: confidentiality, integrity and availability. This triad, although simple, is a widely applicable model that is the backbone of many of the General Data Protection Regulations (GDPR) which governs how organisations in the EU should operate in regards to personal data and information.


Confidentiality can be defined as only authorised personnel having access to data and information. One example of confidentiality being comprised is a data breach, where private information has been leaked to an untrusted audience. In a business setting, a breach of this nature can destroy client trust and cause dire effects to the business.


Integrity involves protecting data from being modified by unauthorised access and ensuring that the data is stored is accurate. There are controls that can be put into practice in order to maintain the integrity of sensitive information when being stored or transferred.


The final principle is availability. Information is rendered useless if there is no guarantee of access to those who are authorised to do so. The availability principle dictates that information has to be readily available for users to access at any given time, therefore any system that stores and protects data has to be operating faultlessly at all times. Protocols such as backups or duplicating data are a good way to ensure availability of information in the event of an unforeseeable event (e.g., a network crash).

How to Implement Information Security Measures in a Business Setting?

Information security measures are essential for businesses of all sizes and types in order to protect sensitive data. Cybersecurity must be taken seriously as it is important to identify, protect, detect, respond, and recover from cybersecurity threats. Implementing information security measures is a multi-faceted process that requires the evaluation and implementation of appropriate security controls.

This includes encrypting data in transit and using end-to-end encryption for communication. IT security teams should also be assigned to regularly assess the system for vulnerabilities and patch them immediately when detected. Additionally, organizations should invest in data protection tools such as firewalls or access control systems to limit access to confidential information. These steps will ensure that the organization remains safeguarded from cybersecurity threats at all times.

Different Types of Security Threats and How to Prevent Them

​Data breaches have become an increasingly common occurrence, leading to an increased need for information security management in various industries. Data protection should be a priority for any organization that stores important or sensitve information; this includes implementing access management policies, as well as regularly updating software and systems that are used to store off-site information.

While businesses need to take greater precautions against potential attacks, it’s also crucial for individual users to take responsibility for their own information security, such as keeping devices safe from malware and backing up data at regular intervals, having strong authentication measures in place is essential for reducing potential risks associated with data theft or malicious attacks. By taking a proactive approach to security threats and learning about different types of risks, everyone can do their part in preventing data losses and protecting sensitive information.

The Role of Employee Training and Education in Maintaining Information Security

Information Security Governance is critical to the security of any organization. Employee Training and Education are integral components to Information Security Governance, as they provide employees with the skills and knowledge they need in order to remain compliant with regulatory requirements such as the General Data Protection Regulation. Through training and education staff become aware of their individual roles and responsibilities in Information Security Governance, protecting an organization's data, physical assets and intellectual property from malicious actors. Creating a culture of Information Security within an organization through effective training and education is key for protecting its data from unauthorized access or threats.

The Definition of IAM

Identity and access management can successfully ensure that the CIA triad are not compromised. The purpose of identity and access management (IAM) is to ensure that the right people have access to the appropriate resources. By identifying, authorising and authenticating users, this system is able to monitor user privileges and the circumstances in which user access is granted or denied. Along with enhancing security, IAM can improve user experience and collaboration as organisations can be confident that any outside access will not jeopardise their resources.

Information security revolves around the business mechanisms that set out to protect and maintain the confidentiality of information. Generating more awareness around the importance of having security controls in place is critical to business operations and company credibility.
