What is Cybersecurity?
Cybersecurity refers to the practice of protecting computer systems, networks, and information from unauthorized access, damage, theft, or disruption. It involves applying various measures such as technologies, processes, and policies to safeguard digital assets against potential threats and vulnerabilities. The purpose of cybersecurity is to ensure the confidentiality, integrity, and availability of data and resources in cyberspace.
Long answer
Cybersecurity encompasses a set of practices implemented to protect computers, servers, mobile devices, networks, software systems, and data from unauthorized access or malicious attacks. The objective is to mitigate risks associated with unauthorized disclosure or alteration of information while preserving its availability for legitimate users.
The rapid growth of interconnected systems has resulted in an increased dependency on technology for businesses and individuals alike. While this connectivity offers numerous benefits, it also creates a wide range of potential vulnerabilities that cybercriminals exploit to gain unauthorized access or cause harm.
To counter these threats effectively, cybersecurity employs multiple layers of security controls and countermeasures. These measures include network security protocols and firewalls to control traffic flow and detect suspicious activities. Intrusion detection and prevention systems are used to identify any attempts at unauthorized entry into computer systems.
Data encryption techniques are employed to secure sensitive information by converting it into unreadable formats that can only be decrypted by authorized parties. Access controls restrict user permissions based on roles and responsibilities within an organization or system.
Additionally, cybersecurity frameworks encompass proactive monitoring strategies to identify potential threats and respond swiftly when incidents occur. This includes regular vulnerability assessments and penetration testing in order to identify weaknesses in computer infrastructure before they can be exploited by attackers.
