Top 10 Useful Technologies in Cyber Security

However, please note that the cybersecurity landscape is constantly evolving, and new technologies may emerge from time to time. Here is the list based on information available as of September 2021:

1. Artificial Intelligence (AI) and Machine Learning (ML): AI and ML are used to identify patterns and anomalies in large data sets, which can be used for threat detection, fraud prevention, and behavioral analysis.
2. Endpoint Protection: This involves securing individual devices (endpoints) such as computers, smartphones and IoT devices to prevent them from exploiting cyber threats.
3. Firewalls: Firewalls are essential to network security, acting as a barrier between a trusted internal network and untrusted external networks such as the Internet.
4. Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS): IDS monitors network traffic for suspicious activity, while IPS goes a step further by blocking or mitigating these activities in real time.
5. Multi-Factor Authentication (MFA) and Two-Factor Authentication (2FA): These methods add an extra layer of security by requiring users to provide multiple forms of identification before being granted access.
6. Encryption: Encryption technologies protect sensitive data by converting it into a coded form that can only be accessed with a valid decryption key.
7. Security Information and Event Management (SIEM): SIEM tools collect and analyze data from various sources within a network, helping to detect and respond to security incidents.
8. Vulnerability Assessment and Penetration Testing (VAPT): These processes identify and assess vulnerabilities in systems, applications, and networks, followed by penetration testing to simulate real-world attacks.
9. Zero Trust Architecture: This approach emphasizes that no user, device or system should be trusted by default, requiring constant authentication to access resources.
10. Bockchain Technology: Although commonly associated with cryptocurrencies, blockchain’s decentralized and tamper-proof nature has potential applications for securing digital identities, transactions, and more.

Remember that the cybersecurity field is dynamic, and new technologies continue to emerge. To get the most accurate and up-to-date information about the top usable technologies in cybersecurity in 2023, I recommend consulting recent industry reports, cybersecurity websites, or experts in the field.
