Learn Network Security with Free Lessons & Tips

Hello Amanpreet, PGP, or Pretty Good Privacy, is a network security program that encrypts and decrypts messages, verifies the source of emails, and authenticates messages with digital signatures. It's used to secure sensitive information, such as emails and files, and is considered the standard for email security. 

Hello There, Network security is the practice of securing computer networks from attack. These networks typically handle sensitive information, such as customer data and financial data. As such, it's important to keep network security strong. If it isn't, hackers can steal this data and cause a host of other problems.

Network security primarily addresses threats that exploit network vulnerabilities and impact data transmission, such as DDoS attacks and MitM attacks. Cyber security addresses a wider range of threats at the system level, including social engineering attacks, data breaches, and advanced persistent threats (APTs).

Hello Annu, Cloud network security is a set of technologies, processes, controls, and policies that protect cloud networks from unauthorized access, modification, misuse, or exposure. It's a key part of cloud security and is important because sensitive information is often migrated to the cloud, making it more vulnerable. 

Cloud network security protects data, applications, virtual machines, and infrastructure in the cloud. It helps prevent network-based attacks like ransomware, cryptojacking, and BotNetC2.

Hello Vishal. Its a kind of a cyber attack. A masquerade attack is a cyber attack where an unauthorized entity gains access to a system or network by impersonating a legitimate user or device. The attacker uses stolen credentials or login information to bypass security controls and gain access to sensitive information. 

Masquerade attacks can be used to: steal sensitive information, launch further attacks from within the compromised network, manipulate business transactions, commit financial crimes, and halt business operations.
