Cyber Security vs. Information Security

Cyber security is the capacity to secure, defend and protect electronic data from attacks and exploitation in servers, mobile devices, computers, networks, and other devices. For preserving this data, it is important to identify the risks to which the data is exposed and the location of the data. It protects critical and sensitive information against threats and unauthorised intrusions.

It is a form of data security which is also known as infosec and refers to data protection using various forms and strategies. It provides access to data to only a few authorised people, unlike cyber security, which involves security from cybercrime. As a professional in this field, one must maintain the data’s confidentiality, integrity, and availability (CIA). Today, most data is stored in electronic devices such as computers, servers, or in cloud storage.

Data protection from unauthorised access and malicious activity is the main aim in the fields of information security and cyber security, which are closely related. People often confuse the two terms, but they have distinct differences.

Information Security focuses on safeguarding all forms of data, regardless of its location or format. This includes electronic files, physical documents and any other information that holds important value for an organisation. The main work of Information Security personnel is to give assurance for the security, privacy, and accessibility of data by implementing appropriate measures such as access controls, encryption, backups, and disaster control plans. Information Security professionals prioritise understanding the data sources and assessing potential risks before addressing specific threats.

On the contrary, Cyber Security primarily protects digital data in cyberspace from external threats. Its main objective is to protect data that is stored, processed, or moved across computer systems and the internet. Protecting against viruses, malware, trojans, attackers, and other dangerous actions that can endanger the privacy, reliability, and accessibility of digital data is the responsibility of cyber security experts. They use technologies like intrusion detection systems, firewalls, antivirus programmes, and safe network setups to deal with advanced and complex threats.

While information security covers a broader scope, including physical and non-digital data, cyber security specifically concentrates on securing data in online platforms. Information security professionals often lay the foundation for overall data protection by implementing measures to secure data sources, whereas cybersecurity experts focus on combating cyber threats that specifically target digital information.

Information security and cybersecurity overlap in several ways, including shared security practices and similar educational requirements and skill sets.

One of the critical areas of overlap is using the CIA triad model to develop security policies. Both information security and cybersecurity professionals want to preserve the confidentiality of data by limiting access to authorised individuals and protecting it from any kind of unauthorised disclosure. They also focus on maintaining the originality of information, ensuring it is accurate, not altered, and reliable.

In the field of education and skills, information security and cybersecurity careers often require a bachelor’s degree in cybersecurity, IT, computer science, or any related disciplines. These degree programs provide a foundational understanding of security principles, technologies, and practices. Professionals in both fields also benefit from being familiar with several technologies, including database user interface and query software, virus-protecting tools, network monitoring software, and web platform development. Information security and cybersecurity professionals need to have strong analytical and problem-solving abilities and a clear understanding of computer systems and networks. They should be knowledgeable about security protocols, encryption techniques, and risk assessment methodologies. Effective communication and teamwork skills are also essential, as they often collaborate with colleagues and stakeholders to address security issues.

While information security and cybersecurity have distinct focuses and areas of expertise, they share standard security practices and require similar educational backgrounds and skill sets. This similarity allows professionals in these fields to collaborate together to protect data and reduce or avoid risks.

Careers options for both information security and cybersecurity are addressed in this section.

Information Security

Information Security Analyst

The individuals in this position are responsible for planning, monitoring, and implementing security measures to protect computer networks and information. They may also create reports on security metrics and data breaches.

Information Security Specialist

Similar to analysts, information security specialists work on developing and implementing information risk management frameworks, standards, and policies. They assist users in accessing databases and participate in risk assessments.

IT Security Consultant

IT security consultants assess and recommend improvements to an organisation’s information security. They support data privacy improvements, identity access management systems, cybersecurity management and operations.

Cyber Security

Cybersecurity Analyst

The analysts focus on protecting data from cyberattacks. They detect threats and incidents and respond to data breaches. They may also develop cybersecurity awareness training and conduct forensic analysis.

Cybersecurity Engineer

These professionals oversee the development of cybersecurity procedures and policies. They build and maintain firewalls, develop security controls for digital files, and monitor and respond to security breaches.

Penetration Tester

Penetration testers identify vulnerabilities in systems by conducting simulated cyberattacks. They exploit systems and gain access to sensitive information to suggest security solutions and improvements for better defences against malicious attacks.

Salary ranges for these roles can vary depending on experience, location, and industry demand.

Professionals have to deal with different types of cyber security regularly. Some of them are:

Network Security

This protects computer networks from misuse, unauthorised access, interruptions, and service disruptions. It involves implementing firewalls, intrusion detection systems, and virtual private networks (VPNs) to protect network infrastructure.

Cloud Security

It has a set of procedures, controls, technologies, and policies that work together to keep cloud-based systems and infrastructure secure. It involves measures to protect data stored in the cloud, secure cloud-based applications, and ensure the privacy and compliance of cloud environments.

Application Security

Application security involves processes to detect, fix, and enhance the security of applications. It aims to prevent hackers from exploiting application vulnerabilities to gain unauthorised access or steal sensitive data. Application security measures include code reviews, vulnerability assessments, and penetration testing.

Critical Infrastructure Security

It focuses on protecting essential systems and services that are vital for the functioning of society, transportation systems, and network communication. It involves implementing security measures to safeguard critical infrastructure from cyber threats, which can have severe consequences if compromised.

These are just a few examples of the types of cyber security professionals work with. Each type of cyber security addresses specific threats and requires specialised knowledge and tools to protect against them effectively.

There are different types of Information Security measures organisations employ to protect their data:

Access Controls

It determines who can access the organisation’s network and data. They involve restricting physical and virtual access to the company’s infrastructure. To ensure that only people with the proper authorisation can access sensitive information, this includes authentication of users, approval, and other procedures.

Compliance Controls

Compliance controls focus on maintaining cybersecurity standards and privacy laws. They enforce requirements for data security and often involve conducting risk assessments, implementing data protection measures, and ensuring compliance with relevant regulations.

Procedural Controls

It helps to detect and reduce security risks to physical assets and overall organisational security. They involve establishing procedures and guidelines for security practices, conducting security awareness training for employees, implementing incident response plans, and establishing a security framework to manage and mitigate security risks.

Technical Controls

Technical controls cover different technological measures to enhance security. This includes implementing multi-factor authentication (MFA) for login, using antivirus software and firewalls to protect against malware and unauthorised access, encrypting data, and employing intrusion detection and prevention systems. These controls add an extra layer of security to protect the organisation’s data and systems.

The two types of data security are vital for the security of organisational data.  Learning about the criticalities of these two segments requires proper guidance and resource. You must participate in a training programme in this field if you want to work as a certified cyber security professional in a reputable company earning a high salary.
