What is the difference between cybersecurity and information security?

Information Security and CyberSecurity are often confused. InfoSec is a crucial part of cybersecurity, but it refers exclusively to the processes designed for data security. Cybersecurity is a more general term that includes InfoSec.

What is an information security management system (ISMS)?

An ISMS is a set of guidelines and processes created to help organizations in a data breach scenario. By having a formal set of guidelines, businesses can minimize risk and can ensure work continuity in case of a staff change. ISO 27001 is a well-known specification for a company ISMS.

Types of Information Security

Application Security
Application Security
Application security is a broad topic that covers software vulnerabilities in web and mobile applications and application programming interfaces (APIs). These vulnerabilities may be found in authentication or authorization of users, integrity of code and configurations, and mature policies and procedures. Application vulnerabilities can create entry points for significant InfoSec breaches. Application security is an important part of perimeter defense for InfoSec.
Cryptography
Cryptography
Encrypting data in transit and data at rest helps ensure data confidentiality and integrity. Digital signatures are commonly used in cryptography to validate the authenticity of data. Cryptography and encryption has become increasingly important. A good example of cryptography use is the Advanced Encryption Standard (AES). The AES is a symmetric key algorithm used to protect classified government information.
Incident Response
Incident Response
Incident response is the function that monitors for and investigates potentially malicious behavior. In preparation for breaches, IT staff should have an incident response plan for containing the threat and restoring the network. In addition, the plan should create a system to preserve evidence for forensic analysis and potential prosecution. This data can help prevent further breaches and help staff discover the attacker.
Cloud Security
Cloud Security
Cloud security focuses on building and hosting secure applications in cloud environments and securely consuming third-party cloud applications. “Cloud” simply means that the application is running in a shared environment. Businesses must make sure that there is adequate isolation between different processes in shared environments.
Infrastructure Security
Infrastructure Security
Infrastructure security deals with the protection of internal and extranet networks, labs, data centers, servers, desktops, and mobile devices.
Vulnerability Management
Vulnerability Management
Vulnerability management is the process of scanning an environment for weak points (such as unpatched software) and prioritizing remediation based on risk. In many networks, businesses are constantly adding applications, users, infrastructure, and so on. For this reason, it is important to constantly scan the network for potential vulnerabilities. Finding a vulnerability in advance can save your businesses the catastrophic costs of a breach.
