What is Cybersecurity ? Full Guide and Information 👍 Must View !

 

Cybersecurity refers to the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users; or interrupting normal business processes.

Key aspects of cybersecurity include:

1. Network Security: Protecting the network from intruders, whether targeted attackers or opportunistic malware.

2. Application Security: Keeping software and devices free of threats. A compromised application could provide access to the data it is designed to protect.

3. Information Security: Protecting the integrity and privacy of data, both in storage and in transit.

4. Operational Security: Includes the processes and decisions for handling and protecting data assets. The permissions users have when accessing a network and the procedures that determine how and where data may be stored or shared all fall under this umbrella.

5. Disaster Recovery and Business Continuity: Defining how an organization responds to a cyber-security incident or any other event that causes the loss of operations or data. Disaster recovery policies dictate how the organization restores its operations and information to return to the same operating capacity as before the event. Business continuity is the plan the organization falls back on while trying to operate without certain resources.

6. End-user Education: Addressing the most unpredictable cybersecurity factor: people. Anyone can accidentally introduce a virus to an otherwise secure system by failing to follow good security practices. Teaching users to delete suspicious email attachments, not plug in unidentified USB drives, and various other important lessons is vital for the security of any organization.

Cybersecurity measures can be divided into three categories:

1. Preventive Measures: These include firewall protection, encryption, and access control measures to prevent unauthorized access.

2. Detective Measures: These are tools and strategies to identify and detect cyber attacks. Intrusion detection systems (IDS) and monitoring systems fall under this category.

3. Corrective Measures: These are steps to take after a cyber incident to restore systems and data to their previous state and to prevent future incidents. This includes backups, disaster recovery plans, and patch management.
