What does cyber security do? — VoltronAI

Cybersecurity is the practice of protecting computer systems, networks, and sensitive information from unauthorized access, theft, and damage. The need for cybersecurity has grown significantly in recent years due to the increasing amount of sensitive information being stored and transmitted digitally, as well as the rising number of cyber threats and attacks.

Cybersecurity professionals use a range of tools and techniques to safeguard computer systems and networks from cyber threats, such as viruses, malware, and phishing attacks. These techniques include:

Authentication and Access Control: This involves verifying the identity of users attempting to access a system or network, and granting them appropriate access privileges based on their role or level of clearance. Authentication mechanisms can include passwords, biometrics, and multi-factor authentication.

Encryption: Encryption is the process of encoding data in a way that makes it unreadable to unauthorized users. This is typically done using cryptographic algorithms and keys.

Firewalls: Firewalls are hardware or software-based security systems that monitor and control incoming and outgoing network traffic. They can be configured to block traffic from known malicious sources, or to allow traffic only from trusted sources.
