What is Information Security?

How does cybersecurity differ from information security?

Cybersecurity and information security are often confused. Information security, or InfoSec, is a crucial component of cybersecurity, but only refers to the processes designed to protect data. In general, cybersecurity includes InfoSec.

What is an information security management system (ISMS)?

Information Security Management Systems are created to assist organizations in the event of a data breach. Businesses that have formal guidelines can minimize risk and ensure work continuity in case of a staff change. A company ISMS needs to meet the requirements of ISO 27001, which is a well-known standard.

What is the General Data Protection Regulation (GDPR)?

The European Parliament and Council adopted the General Data Protection Regulation in 2016. Companies have since been required to comply with the GDPR by:

• provide data breach notifications
• appoint a data-protection officer
• require user consent for data processing
• anonymize data for privacy
• All companies operating within the EU must comply with these standards.

What certifications are needed for cybersecurity jobs?

Cybersecurity jobs typically require a variety of certifications. Some companies require vendor-specific training for their chief information security officer (CISO) or certified information security manager (CISM).

Organizations such as the International Information Systems Security Certification Consortium offer security certifications that are widely accepted. A range of certifications are available, from CompTIA Security+ to the Certified Information Systems Security Professional (CISSP).

Types of InfoSec

Application security

Web and mobile application security includes software vulnerabilities in APIs and application programming interfaces (APIs). A vulnerability could occur in the authentication or authorization of users, the integrity of code and configurations, or mature policies and procedures. Information security breaches can arise from application vulnerabilities. Information security breaches can occur through application vulnerabilities.

Cloud security

The goal of cloud security is to build and host secure applications in cloud environments, and to consume third-party cloud applications securely. A cloud application runs in a shared environment. Businesses must ensure that different processes in shared environments are adequately isolated.

Cryptography

It is important to encrypt data in transit and at rest to ensure its confidentiality and integrity. In cryptography, digital signatures are commonly used to verify the authenticity of data. Encryption and cryptography are becoming increasingly important. The Advanced Encryption Standard (AES) is a good example of how cryptography is used. The AES algorithm is used to protect classified government information.

Infrastructure security

Security for infrastructure includes labs, data centers, servers, desktops, and mobile devices, as well as internal and extranet networks.

Incident response

Monitoring and investigating potentially malicious behavior is the function of incident response.

Prepare your IT staff for breaches by creating an incident response plan for containing the threat and restoring the network. Additionally, there should be a plan for preserving evidence for forensic analysis and potential prosecution. This data can assist with preventing future breaches and help uncover the attacker.

Vulnerability management

An environment is scanned for weak points (such as unpatched software) and remediation is prioritized according to risk using vulnerability management.

Businesses constantly add applications, users, and infrastructure to their networks. The network must be constantly scanned for vulnerabilities, for this reason. Businesses can avoid the catastrophic costs of a breach by identifying vulnerabilities in advance.
