In this post we are going to learn about what id information security its need and type.
Defination of information security:
Security of information does not simply mean preventing unauthorized access to it. Security of information means preventing an unauthorized person from gaining access to, using, disclosing, modifying, inspecting, recording or destroying data. It refers to both physical and electronic information. You can provide information such as your contact information, your profile on social media, your phone number, biometrics, etc.
There are three main objectives of an Information Security program, commonly referred to as CIA, Confidentiality, Integrity, and Availability.
Confidentiality:
In this day and age, data leaks are on the rise, and lots of data have already been exposed, thus we need to secure our data from cyber attackers by fixing vulnerabilities on many platforms, such as websites, mobile applications, cloud servers, etc.
Integrity:
Integrity is the quality of being whole or complete. Integrity in InfoSec refers to the verification that data has not been tampered with and, thus, can be trusted. It is correct, authentic, and reliable.
Availability:
CIA Triad refers to the actual availability of your data and is the final component. All authentication mechanisms, access channels, and systems must function properly for the information they protect and ensure it is available when needed.

Data security is the practice of preventing unauthorized access to and alteration of data as it goes from one machine or location to another, whether that data is being stored or transmitted. Data security might also be referred to as data protection.
When critical issues arise, information assurance means ensuring that information isn't compromised in any way. Information assurance forms the basis of Information Security. Natural disasters, computer/server malfunctions, etc. are not the only issues that may arise.
Information security vs cybersecurity
You will sometimes see information security and cybersecurity used interchangeably with information technology, a buzzword that refers to "computers and related stuff
Information security is a specific discipline within cybersecurity, which is more generally known as cybersecurity. In addition to information security, network security and application security focus on networks and app code, respectively.
Cybersecurity and information security differ in other ways as well. In contrast to cyber security, information security relates to protecting the data not only in cyberspace, but also in the physical world. Also, it might only be part of the larger picture if the Internet or endpoint devices are involved. In both cases, we are defending cyberspace from malware and hacks, which can take all kinds of forms, including ransomware, spyware, and malware. But cyber security professionals have a narrower scope.
Technology-related threats are primarily addressed by cybersecurity, with practices and tools that can prevent or mitigate them. An organization's data must be protected from accidental or malicious exposure to unauthorized parties, which is another related category.
Information Security Policy
The policies dictate the behavior and responsibilities of employees, as well as how cybersecurity tools should be procured.Companies can develop information security policies to ensure that employees and other users comply with security protocols and procedures. Security policies aim to protect sensitive systems and information by restricting access to authorized users.
Purpose:
Information security policy should specify the aims and sense of the set up and its objectives. A data compromise is prevented, signaled, and detected by preventing, stopping, and detecting actions that could result in a compromise.
Scope:
There should be a complete outline of the company's information security processes like the individual networks, routers, servers, and the configuration of the entire network as well as all the users who are part of the company's programs. Any third party users from anywhere in the world should be covered, as should all remote systems and remote users.
Objectives:
An information security policy should be well written, not wordy, and should clearly state the organization's information security objectives in unambiguous terms to prevent any confusion or disputes in the future.
Security measures include hardware and software that protect data - everything from encryption to firewalls
Among organizational measures are creation of an internal information security unit and inclusion of information security duties in every department
awareness training for employees is also an important human measure
Controlling access to office locations and, particularly, data centers is another physical measure.
TYPES OF INFORMATION SECURITY
Application Security: Application Security is very important we all know that anyone can use website,mobile app,API and so on this types of application is easily accessable to anyone so attacker can take advantage of this and try to attack your applications.
Software, web, and application programming interface vulnerabilities are covered in this report. In addition to vulnerabilities in user authentication, there can be other entry points that can make an organization vulnerable to potential threats and information security breaches.
Information Security: There is a need to secure the entire infrastructure associated with this area.
Cloud Security: A secure infrastructure for building and hosting client applications involves a shared cloud environment and information security.Several organizations use kubernetes to migrate to the cloud. Securing kubernetes is also important
Cryptography: Many fields rely on encryption and cryptography for information security. Encryption is very important to create secure communication and also store user data in encrypred form on website or mobile application to prevent data breaches
Vulnerability Management: Screening is conducted in order to identify potential weak spots in each area of the system. It is crucial that organizations continue to update their hardware and add new applications in an era when it is essential that any weak or vulnerable points are patched as soon as possible.
