To secure your server, implement strong passwords, regularly update software, use firewalls, enable encryption, conduct regular security audits, and establish access controls. Additionally, monitor logs for unusual activity and create backup solutions to protect against data loss.

A firewall is a security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It is used to protect networks from unauthorized access, malware, and other cyber threats, ensuring a safe online environment.

Yes, mobile devices can pose security risks due to vulnerabilities in apps, outdated software, and insecure networks. They can be targeted by malware, phishing attacks, and data breaches, making it essential to implement security measures like encryption, strong passwords, and regular updates.

Encryption is the process of converting data into a coded format to protect it from unauthorized access, ensuring privacy and security. Hacking, however, involves exploiting vulnerabilities in systems to gain unauthorized access to data or networks, often with malicious intent. While encryption secures information, hacking seeks to compromise it.

The costs of a cyber attack can be significant, including direct financial losses from theft, legal fees, regulatory fines, and recovery expenses. Additionally, businesses may face reputational damage, loss of customer trust, downtime, and increased cybersecurity measures, which can all lead to long-term financial impacts.
