What Is InfoSec? Definition + Career Guide

InfoSec, or information security, keeps data and information safe from bad actors. InfoSec is a type of cybersecurity focused on implementing technology to keep data safe and includes application security, cloud security, incident response, and more. Within the industry, you can explore a variety of jobs, from creating security architecture to responding when incidents occur. 

Explore how InfoSec professionals keep information safe and how you can start a career in the field, including job titles, average salaries, and how to begin. 

What is InfoSec?

InfoSec stands for information security. It refers to the practices, systems, and processes that protect sensitive information from risks and vulnerabilities. Information security is essential to data confidentiality, integrity, and availability. Data must be secured in three states:

1. At rest: Data not currently being used or accessed, such as stored on a hard drive or server.

2. In transit: Data in the transmission process from one location to another. This could be over a network or the internet.

3. In use: Data accessed by an individual or system.

Types of InfoSec

InfoSec has several subcategories. InfoSec professionals may choose to specialise in certain areas. A few common subsets of InfoSec you may come across as you continue to research InfoSec and InfoSec jobs include:

• Information security management. InfoSec professionals are responsible for establishing organisational systems and processes that protect information from security issues inside and outside the organisation. ISO27001 is the international standard for information security. It concerns all aspects of information security, including managing files, databases, applications, websites, laptops, desktops, and mobile devices.

• Application security. Securing applications encompasses hardware, software, and procedural methods to safeguard applications against external threats. Examples include code signing, verification, input validation, high-level authentication, code improvement, and software monitoring.

• Cloud security. Cloud security protects data and resources stored in or accessed through a cloud computing environment. Cloud security includes measures to prevent, detect, and respond to attacks on cloud resources. You’ll protect data confidentiality, integrity, availability, and compliance in your cloud environments.

• Cryptography/algorithmic encoding. Cryptography secures communication in a situation where third parties could intercept your data. You may use cryptographic mathematical algorithms to encode and decode data. These measures can help protect information from unauthorised access and ensure that data remains unchanged during transmission.

• Infrastructure security. Infrastructure security protects a computer system's physical and logical components. Security protects your non-computing physical infrastructures, such as buildings, telecommunications networks, and power grids, from damage or destruction.

• Incident response. Incident response describes the identification, containment, eradication, and recovery from a security incident. InfoSec processes included in incident response include incident handling, forensics, and business continuity planning. InfoSec professionals in this role work to prevent incidents from happening and respond if they do occur.

• Vulnerability management/risk assessment. Vulnerability management identifies, understands, and mitigates weak points in systems and processes. It includes processes like vulnerability assessment, vulnerability mitigation, and threat modelling.

InfoSec vs cybersecurity

Cybersecurity is a subset of InfoSec. Both focus on security and technology. However, InfoSec is more data-centric. InfoSec interventions focus on protecting information. Cybersecurity emphasises cyber threat detection and ensuring robust security for technological systems. 

Is InfoSec worth it to businesses?

The importance of InfoSec has grown over time due to the increased threat of security breaches and greater levels of data collection overall. The development of new technologies has also pushed InfoSec to the forefront. As technology advances, the need for improved threat prevention strategies grows. Even the government has to protect itself from malicious attacks, such as those led and organised by hacktivist groups like Dragon Force. Implementing robust information security practices can make it more difficult for unauthorised users to access and misuse data. Explore additional reasons that InfoSec is critical:

• InfoSec compliance. You must protect sensitive information to comply with specific standards, regulations, and laws.

• Financial loss and brand image issues. Damage repair after a data breach includes reputation management and costly information recovery efforts.

Common information security threats

Organisations face numerous information and data threats every day. Routine risk assessments to mitigate them are vital. The motivations behind an InfoSec attack may include financial gain, theft of sensitive information, or to cause harm and disruption. Discover common InfoSec threats to be aware of, including property theft, malware, identity theft, social engineering, information theft, and sabotage.

Intellectual property theft

Intellectual property theft is the unauthorised use or reproduction of copyrighted material, trade secrets, or other proprietary information. This occurs through cybercrime, espionage, or malicious behaviour from employees (authorised users within an organisation misusing company information).

Malware

Malware attacks are a type of cyberattack that targets vulnerabilities in your software to gain access to systems or data. Common software attacks include SQL injection, buffer overflow, denial of service (DoS), and cross-site scripting.

Identity theft

Identity theft occurs when personally identifiable information is accessed and used to commit fraud or other crimes. This can happen when someone steals physical identity documents, such as a driver's licence or passport. Identity theft happens digitally when someone obtains personal information online through phishing or other methods. If your company holds personal information, you must safeguard it to protect users from identity theft.

Social engineering

Social engineering is deception and manipulation. It aims to convince you or someone else to divulge confidential information or perform a specific action. People in your company may receive a social engineering attack on the phone, through email scams, or in person. The goal of social engineering is typically to gain access to your systems or data. However, it can also be weaponised to extort your company for financial gain or other motivations.

Information theft and equipment theft

Many companies are affected by the theft of physical equipment, such as computers or servers, or digital information, such as confidential files or customer data. Your company might be targeted for financial gain, to gain a competitive advantage, or to cause harm to your organisation.

Sabotage

Sabotage is any deliberate action to damage or destroy your equipment, systems, data, or facilities. People inside or connected with your company may have malicious intent, or outside attackers may gain access to your organisation's systems.

InfoSec jobs

As an information security professional, you will protect data from unauthorised access, use, disclosure, disruption, modification, or destruction. You will manage the InfoSec process using information security standards and InfoSec frameworks, protocols, and controls. These practices will help you address security vulnerabilities regularly (typically weekly or monthly).

What is it like to work in InfoSec?

A career in information security is exciting and varied, with many specialisations available. Technical roles may involve working with security technologies to protect networks and systems, while non-technical roles may focus on developing policies and procedures or conducting risk assessments. Analytical and critical thinking skills are essential in all aspects of the field, as they are needed to identify potential threats and vulnerabilities and to develop effective mitigation strategies.
