What Is InfoSec? Meaning, Jobs, Certification, and More

Infosec meaning

Information security, or InfoSec, refers to the practices, systems, and processes used to protect sensitive information from risks and vulnerabilities. Information security is essential to data confidentiality, integrity, and availability.

For data to be secured, it must be protected in each of the following states: (1) at rest, or when the data is not currently being used or accessed; (2) in transit, or when the data is being transmitted from one location to another like over a network or the internet; and (3) in use, or when it is being accessed by an individual or system.

InfoSec types

InfoSec has several subcategories in which professionals may choose to specialize. Here are a few common subsets of InfoSec you may come across as you explore jobs in the field:

• Information security management. InfoSec professionals are responsible for establishing organizational systems and processes that protect information from security issues inside and outside the organization. ISO27001 is the international standard for information security. It is concerned with 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, code verifying, 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 unauthorized access and ensure that data remains unchanged during transmission.

• Infrastructure security. Infrastructure security protects a computer system's physical and logical components. Infrastructure 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 modeling.

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 more broadly emphasizes cyber threat detection and ensuring robust security for technological systems.

Why is InfoSec Important?

InfoSec's importance has grown over time due to the increased threat of security breaches and greater levels of data collection overall. As technology advances, the need for improved threat prevention strategies only grows.

Implementing robust information security practices can make it more difficult for unauthorized users to access and misuse data. Here are a couple of 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 for a data breach includes reputation management in addition to costly information recovery efforts.

Common information security threats

Organizations 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. The next few sections outline common InfoSec threats to be aware of.

1. Intellectual property theft

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

2. 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.

3. 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 license or passport. Identity theft also 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.

4. 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 weaponized to extort your company for financial gain or other motivations.

5. 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, for the antagonists to gain a competitive advantage, or to cause harm to your organization.

6. 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 organization's systems.
