What Is Information Security (Infosec)?

Information security, often referred to as infosec, is the practice of protecting information from unauthorized access, disclosure, alteration, and destruction. The core objective of information security is to ensure information confidentiality, integrity, and availability—collectively known as the CIA triad.

1. Confidentiality: Ensuring that information is only accessible to those authorized to view it.
2. Integrity: Maintaining the accuracy and completeness of information and processing methods.
3. Availability: Ensuring that information and critical systems are available when needed by authorized users.

Information security encompasses a wide range of protective measures for both physical and digital information. This includes safeguarding physical records, implementing strict access controls, and enforcing policies that govern information handling. Examples of information security practices include information assurance, end-point security, and physical security measures​.

What Is Cybersecurity?

Cybersecurity, a subset of information security, focuses specifically on protecting computer systems, networks, and digital data from cyberattacks. The aim of cybersecurity is to defend these systems against unauthorized access, disruptions, and attacks, particularly those that occur via the internet.

Cybersecurity encompasses a variety of protective measures tailored to digital environments, including network security, application security, and cloud security. Cybersecurity professionals implement technologies such as firewalls, intrusion detection systems, and encryption to protect against threats like malware, phishing, and ransomware attacks​.

Primary Focus Areas

Information Security

The primary focus of information security is to protect a broad spectrum of information types, including digital data, physical records, and intellectual property (IP). 

Information security professionals aim to prevent unauthorized access, use, disclosure, disruption, modification, or destruction of information. Their efforts ensure the confidentiality, integrity, and availability of information across various formats and storage methods.

1. Variety of Information: Information security safeguards digital data stored on computers and physical documents kept in archives. This broad approach means that information security policies and procedures must address the protection of both electronic and physical records.
2. Security Policies: Information security involves creating and enforcing security policies that govern information handling, storage, and transmission. These policies might include access controls, data classification schemes, and information handling procedures.
3. Physical Security: Protecting information also involves securing physical locations, such as offices and data centers, to prevent unauthorized physical access to sensitive information. Measures can include locks, surveillance systems, and security personnel​.

Cybersecurity

Cybersecurity focuses specifically on protecting digital data and the technologies that store process, and transmit this data. This narrower focus addresses the unique threats posed by cyberattacks, which target computer systems and networks.

1. Digital and Network Security: Cybersecurity is concerned with protecting internet-connected devices, systems, and technologies. This includes securing networks, applications, and cloud services from cyber threats such as hacking, malware, and phishing attacks.
2. Technological Measures: Cybersecurity professionals implement a range of technologies to defend against cyber threats. Common tools and practices include firewalls, intrusion detection systems, encryption, and multi-factor authentication.
3. User Training: Because human error is a significant factor in many cyber incidents, cybersecurity also involves training users on best practices to recognize and avoid threats. This can include education on phishing scams, secure password practices, and the importance of regular software updates​.

Security Methods and Practices

Information Security Methods

Information security employs a range of methods designed to protect information in various forms. These methods focus on establishing comprehensive policies and procedures to safeguard both digital and physical data.

1. Securing Physical Archives: One of the fundamental aspects of information security is protecting physical records from unauthorized access or damage. This can involve secure storage solutions, such as locked cabinets and restricted access to sensitive areas.
2. Confidentiality Rules for Intellectual Property (IP): Information security also encompasses creating and enforcing rules to maintain the confidentiality of intellectual property. This might include non-disclosure agreements, secure document handling protocols, and encryption of digital files.
3. Comprehensive Security Policies: Organizations develop and implement extensive security policies that outline how information should be handled, stored, and transmitted. These policies are designed to ensure compliance with regulatory requirements and to protect against potential threats.

Cybersecurity Methods

Cybersecurity focuses on protecting digital information and the systems that manage it. This involves a variety of technical measures and user-focused strategies to prevent, detect, and respond to cyber threats.

1. Network and Computer System Security: Cybersecurity professionals use technologies such as firewalls, intrusion detection systems, and antivirus software to protect networks and computer systems from unauthorized access and attacks. These tools help to detect and block malicious activity before it can cause harm.
2. Protection Against Specific Threats: Cybersecurity methods are tailored to defend against specific types of cyber threats, such as ransomware, malware, and phishing scams. For instance, encryption ensures that data remains secure during transmission, while regular software updates help patch vulnerabilities that attackers could exploit.
3. Human Factors and User Training: Given that many data breaches involve human error, cybersecurity also emphasizes the importance of training users to recognize and avoid potential threats. This can include training on identifying phishing emails, using strong passwords, and following best practices for data security. Multi-factor authentication is another critical practice that adds an extra layer of security by requiring multiple forms of verification before granting access.

Overlaps Between Information Security and Cybersecurity

While distinct in their focus areas, information security and cybersecurity share common goals and practices aimed at safeguarding information. Both fields aim to protect sensitive data from unauthorized access, breaches, and other threats, ensuring information confidentiality, integrity, and availability.
