Information Security: Goals, Types and Applications

Information Security: Goals, Types and Applications


The realm of information security empowers organizations to shield both digital and analog data. Information Security (InfoSec) covers a range of elements including cryptography, mobile computing, and social media. It also spans the systems, networks, and environments that store confidential, financial, and corporate information.. In contrast, cybersecurity focuses on safeguarding data, whether in its raw form or with context, exclusively against online threats.


Enterprises adopt information security strategies for a multitude of motives. The primary goals of InfoSec frequently revolve around upholding the confidentiality, integrity, and accessibility of company information. Given the comprehensive nature of InfoSec, it often entails the implementation of diverse security measures. These can span application security, infrastructure security, cryptography, incident response, vulnerability management, and disaster recovery.


Defining Information Security:


Information security, commonly known as InfoSec, encompasses an array of tools and methodologies designed to safeguard both your digital and analog information. This comprehensive discipline spans various domains within IT, including infrastructure, network security, auditing, and testing. Utilizing mechanisms like authentication and permissions, InfoSec seeks to bar unauthorized users from accessing sensitive data, thus mitigating risks associated with information theft, tampering, or loss.


Fundamental Tenets of Information Security


The foundation of Information Security (InfoSec) rests upon three fundamental principles: confidentiality, integrity, and availability, commonly referred to as the CIA triad.


1. Confidentiality


Confidentiality entails shielding information from unauthorized disclosure. The objective of upholding confidentiality is to maintain the privacy of sensitive data, ensuring that it remains visible and accessible exclusively to those with the proper authorization for fulfilling their significant institutional duties.


2. Integrity


The essence of the integrity principle is to guard against any unauthorized alterations to data. It fosters consistency and ensures that data remains accurate, genuine, and unaltered whether through additions, deletions, or other forms of modification. It provides continuous protection against unintended or malicious data changes.


3. Availability


The principal aim of availability is to ensure uninterrupted access to complete data whenever an authorized individual requires it. This implies that availability acts as a shield, ensuring a system's capability to facilitate efficient technological operations, software tools, applications, and data accessibility whenever necessary for institutional tasks or the responsibilities of institutional personnel.

Types of Information Security


Although Information Security manifests in a multitude of forms, the ones most frequently employed within the realm of IT comprise:



Application Security


Application security involves strategies aimed at safeguarding applications and programming interfaces (APIs) from potential threats, such as bugs and unauthorized intrusions. Its attributes encompass elements like documentation, authorization, encryption, and ongoing application security assessments. To bolster their defenses, organizations can adopt secure coding practices to minimize vulnerabilities, employ scanners for continuous detection of emerging weaknesses, and implement Web Application Firewalls to shield public applications from OWASP Top 10 vulnerabilities and other attack vectors.


Infrastructure Security


Infrastructure security pertains to the protection of physical assets including computers, communication systems, and cloud resources. Its objectives span shielding against prevalent cybercrimes, as well as providing resilience against natural disasters and unforeseen incidents. This facet of security significantly contributes to mitigating the potential impact of malfunctions.


Cryptography


Cryptography entails the encryption of data to ensure its confidentiality. This information security technique employs codes to safeguard sensitive information against cyber threats. The process involves applying mathematical principles and a sequence of algorithmic calculations to transform messages in a manner that is intricate to decipher or decode, enhancing data security.


Cloud Security 


Cloud Security pertains to the protection of cloud-connected components, data, applications, and infrastructure, closely related to application and infrastructure security. It concentrates specifically on the domain of cloud computing. Alternatively referred to as cloud computing security, this field encompasses a set of precautions meticulously designed to fortify data, applications, and configurations that exist within the cloud environment.
