The fundamental principles (tenets) of information security are confidentiality, integrity, and availability. Every element of an information security program (and every security control put in place by an entity) should be designed to achieve one or more of these principles.

In the world of information security, integrity refers to the accuracy and completeness of data. Security controls focused on integrity are designed to prevent data from being modified or misused by an unauthorized party.

Putting Confidentiality into Practice

1. Categorize data and assets being handled based on their privacy requirements.
2. Require data encryption and two-factor authentication to be basic security hygiene.
3. Ensure that access control lists, file permissions and white lists are monitored and updated regularly.

The purpose of ‘Confidentiality’ is to ensure the protection of data by preventing the unauthorised disclosure of information. Only individuals with the legitimate authorisation to access the required information should be permitted it, also known as permissions on the “need to know” basis.

Confidentiality means that data, objects and resources are protected from unauthorized viewing and other access. Integrity means that data is protected from unauthorized changes to ensure that it is reliable and correct. Availability means that authorized users have access to the systems and the resources they need.

Types of IT security

• Network security. Network security is used to prevent unauthorized or malicious users from getting inside your network.
• Internet security.
• Endpoint security.
• Cloud security.
• Application security.

The main objectives of InfoSec are typically related to ensuring confidentiality, integrity, and availability of company information….In this article, we’ll look at:

• Application security.
• Infrastructure security.
• Cloud security.
• Cryptography.
• Incident response.
• Vulnerability management.
• Disaster recovery.

Types of Securities

• Equity securities. Equity almost always refers to stocks and a share of ownership in a company (which is possessed by the shareholder).
• Debt securities. Debt securities differ from equity securities in an important way; they involve borrowed money and the selling of a security.
• Derivatives. Derivatives.

Three primary goals of information security are preventing the loss of availability, the loss of integrity, and the loss of confidentiality for systems and data.

The purpose of an information system is to turn raw data into useful information that can be used for decision making in an organization. Many information systems are designed to support a particular process within an organization or to carry out very specific analysis.

The Importance Of Information Security Every organization needs protection against cyber attacks and security threats. Cybercrime and malware are constant threats to anyone with an Internet presence, and data breaches are time-consuming and expensive.

The Principles of Security can be classified as follows:

• Confidentiality: The degree of confidentiality determines the secrecy of the information.
• Authentication: Authentication is the mechanism to identify the user or system or the entity.
• Integrity:
• Non-Repudiation:
• Access control:
• Availability:

Where do Cybersecurity threats happen?

• Application Layer Threats.
• Presentation Layer Threats.
• Session Layer Threat.
• Transport Layer Threats.
• Network Layer Threats.
• Data-Link Layer Threats.
• Physical Layer Threats.

What Are Common Components of a Security System?

• Motion Sensors. Motion sensors are an essential part of any home security system.
• Indoor and Outdoor Cameras. Security cameras are another core security system part.
• Glass Break Detectors.
• Door and Window Sensors.
• Carbon Monoxide Detectors.

8 types of security attacks and how to prevent them

• Malware. Malicious software – ‘malware’ – infects devices without users realizing it’s there.
• Drive-by downloads.
• Phishing.
• Brute-force attacks.
• SQL Injections.
• Man-In-The-Middle (MITM) attacks.
• Denial-of-Service (DoS) attacks.
• Cross-Site Scripting (XSS)

Two types of passive attacks are the release of message contents and traffic analysis. A telephone conversation, an electronic mail message, and a transferred file may contain sensitive or confidential information.

Explanation: Passive and active attacks are the two basic types of attacks.

Examples of information security incidents include: Unauthorized access to, or use of, systems, software, or data. Unauthorized changes to systems, software, or data. Loss or theft of equipment used to store or work with sensitive university data. Denial of service attack.

There are three primary areas or classifications of security controls. These include management security, operational security, and physical security controls.

A security incident is an event that may indicate that an organization’s systems or data have been compromised or that measures put in place to protect them have failed. Unauthorized processing or storage of data. Unauthorized changes to system hardware, firmware, or software.

A security incident is an event that leads to a violation of an organization’s security policies and puts sensitive data at risk of exposure. Security incident is a broad term that includes many different kinds of events. A data breach is a type of security incident.

Physical security is the protection of people, property, and physical assets from actions and events that could cause damage or loss.

A security incident is defined as a violation of security policy. All of these are security incidents (It might seem like “scanning” is not a security incident, but it is a recon attack that precedes other more serious attacks). I disagree with the answer: Malicious code in and of itself is not an incident.

Identifying The Incident

1. Unusual activity detected by proactive monitoring of critical systems or processes.
2. Unusual activity detected during reactive audits or reporting.
3. User reports of unusual observations, or social engineering events.
4. Detection of secondary consequences (e.g., unusual increase in network traffic, or power usage)

One of the most common and widespread security breaches affecting organizations today is a social engineering attack known as tailgating (also referred to as piggybacking). Tailgating is a physical security breach in which an unauthorized person follows an authorized individual to enter a typically secured area.

Here’s how:

1. Keep Only What You Need. Inventory the type and quantity of information in your files and on your computers.
2. Safeguard Data.
3. Destroy Before Disposal.
4. Update Procedures.
5. Educate/Train Employees.
6. Control Computer Usage.
7. Secure All Computers.
8. Keep Security Software Up-To-Date.
