Cybersecurity is the quintessential aspect of businesses worldwide. Gaining traction in this ever-evolving world is one thing, and securing the gathered information is another. The latest news in cybersecurity showcases a heavily compromised business arena concerning their daily operations and breaching their critical information and sensitive data.

With these and many other reports on cyber fraud and information leaks; it is imperative to understand what goes into the world of cybersecurity and how you as a skillful asset work to safeguard the interest of businesses worldwide. It is time to unravel the deep layers of information security and the critical ways to guard against this cyber menace.
What is Information Security?
Information security is the sheer procedure of safeguarding information by mitigating information risks. It involves protecting information, sensitive data, and any information processed, stored, and transmitted by these systems from unauthorized access, use, disclosure, disruption, mishandling, or destruction.
3 Pillars of Information Security:
- Confidentiality– It protects information from unauthorized access or disclosure. Encryption is the key technique used to enforce confidentiality.
- Integrity– It focuses on the accuracy, consistency, and trustworthiness of information throughout its lifecycle. Digital signatures and hash functions are critical ways deployed to strengthen integrity.
- Availability– It ensures that information and systems are accessible and operational when needed. Redundancy and fault-tolerant systems are implemented to minimize downtime and ensure operational continuity.
The CIA triad is the governing factor in information security setup. It strengthens the virtual security guards and makes the entire security system robust enough to counter any malicious cyberthreat attack. Non-repudiation is an added principle that governs the InfoSec as it involves one party that cannot deny receiving a message or a transaction nor can the other party deny sending a message or a transaction.
5 Goals for Information Security:
- Confidentiality
- Availability
- Integrity
- Accountability
- Assurance
The National Institute of Standards and Technology (NIST) has listed the above-mentioned five goals of information security that allow all organizations to meet mission objectives by acknowledging IT-related risks to the organization, its partners, and the customers.
Why is Information Security Indispensable?
Information security is used to protect valuable information assets from a wide range of threats, including theft, espionage, and cybercrime. Information security is critical in today’s times due to the following reasons:
- Protecting sensitive information
- Mitigating risk
- Regulatory compliance
- Reputation safeguards
- Ensuring business continuity
Understanding Information Security Management System (ISMS):
ISMS is a structured framework designed to protect an organization’s information assets. It includes policies, procedures, and controls to manage and secure sensitive data from threats such as unauthorized access, data breaches, and cyberattacks. By following international standards, an ISMS assists organizations in identifying risks, implementing security measures, and continuously improving their security practices to safeguard their information.
5 Types of Information Security:
- Network security– Takes care of computer networks from attacks and unauthorized access using tools such as firewalls, Intrusion detection systems, virtual private networks, etc.
- Application security– Takes care of the software applications by finding and fixing vulnerabilities; using methods such as code reviews, security patches, etc.
- Data security– Takes care of data safety during storage and transfer by using encryption and data masking.
- Endpoint security– Takes care of securing individual devices such as computers, smartphones, and tablets through anti-virus software and endpoint detection and response tools.
- Cloud security– Takes care of protecting the data and applications hosted in cloud environments with measures like secure cloud configurations and identity and access management (IAM).
Popular Information Security Tools and Techniques:
Understanding, deploying, and utilizing popular tools and techniques is essential to attend to any cyberattack. Commonly used InfoSec tools and techniques include cryptography, data loss prevention, endpoint detection and response, firewalls, security operations center, threat intelligence, user and entity behavior analytics, intrusion detection and intrusion prevention systems; and many others.
Potential Challenges Faced by Information Security:
- Cyberthreats
- Human errors
- Increasing complexity of information systems
- Insider threats
- Legacy systems
- Data privacy regulations
- Increasing business globalization
- Integration with third-party systems
