What Is Information Security (InfoSec)

Updated on October 21, 2022, by Xcitium

What is information security?

Information security is the practice of protecting sensitive data, systems, and networks from unauthorized access, misuse, disclosure, disruption, or destruction. It helps ensure the confidentiality, integrity, and availability of information across digital and physical environments.

What Is Information Security Information security is defined as: “the practice of preventing unauthorized access, use, disclosure, disruption, modification, inspection, recording or destruction of information. It is a general term that can be used regardless of the form the data may take (e.g., electronic, physical)” (Wikipedia). InfoSec focuses on the CIA triad, which is to ensure confidentiality, integrity, and availability of data, without affecting organization productivity. Ensuring information security is a multi-step process for risk management. It involves identifying the associated components such as assets, vulnerabilities, threat sources, potential impacts, and possible controls. The effectiveness of the risk management plan is then assessed.

What Is Information Security: Standard of Good Practice for Information Security

The Information Security Forum (ISF) has published the Standard of Great Practice for Data Security, which is a practical and comprehensive, business-focused guide to recognizing and managing InfoSec risks in organizations. The standardization of Information Security took put due to collaboration between academics and professionals. EDR They set fundamental policies and defined standards for factors such as passwords, firewalls, encryption programs, and antivirus programs. Further, laws and regulations were moreover defined on how data was to be handled – its access, processing, storage, and transfer.

Additionally, the need for appropriate change in accordance with continual development was also factored in, as otherwise InfoSec cannot be ensured.

The three principles of information security:

• Confidentiality – Prevent unauthorized access to data
• Integrity – Ensure data remains accurate and unchanged
• Availability – Keep systems and data accessible when needed

Types of information security:

• Network security – Protects networks from attacks
• Application security – Secures software and apps
• Cloud security – Protects cloud-based systems
• Endpoint security – Defends user devices
• Data security – Safeguards sensitive information
• Identity and access management (IAM) – Controls user access

What Is Information Security: Cyber Security Threats to Information Security

There are many forms of threats that target Information Security, and an organization needs to prevent software attacks, identity theft, information sabotage, and data-wiping threats. Ransomware, viruses, Trojans, worms, spyware, rootkits, phishing attacks, and man-in-the-middle attacks are types of software attacks. Ransomware is used to encrypt data (information) and a ransom is demanded for the decryption key. Failure to pay ransom could lead to the deletion of data. According to a Verizon Data Breach Incident Report, 93% of data breaches took place in minutes. And 83% of those breaches were discovered only after a week or several weeks. A single breach costs a financial loss of around $4 million on average, in addition to the loss of consumer trust and damage to the brand. Further, 39% of successful crimeware incidents involved dangerous ransomware.

This scenario showcases the need for an Advanced Endpoint Protection solution to ensure Information security. A huge amount of data gets collected in government organizations, hospitals, data centers, enterprises and other organizations. This data is confidential information and should not fall into competitor hands or other malicious entities.

Why is information security important?

Information security helps organizations:

• Prevent data breaches
• Protect customer privacy
• Reduce cyberattack risks
• Maintain business continuity
• Meet compliance requirements

Without strong information security, businesses face financial losses, downtime, and reputational damage.

Common information security threats:

• Phishing attacks
• Malware and ransomware
• Insider threats
• Weak passwords
• Cloud misconfigurations
• Social engineering attacks

What Is Information Security: Advanced Persistent Threats and Zero-day Malware

To acquire information, cybercriminals employ advanced persistent threats and zero-day malware. Most endpoint security solutions cannot protect against zero-day malware, as they follow a default-allow platform that allows all files except known malicious files. Studies report that signature-based malware engines are only 30% accurate at detecting new threats.

Xcitium’s Advanced Endpoint Protection solution utilizes a Default Deny Platform to provide complete protection against zero-day threats. All unknown files are automatically contained in a sophisticated virtual container where the behavior of the unknown file is observed and a combination of static, dynamic, and human analysis using VirusScope and cloud-based Valkyrie is used to obtain a verdict. Xcitium this method completely blocks unknown threats and ensures information security for the organization.Try it for FREE

FAQ:
