In the digital age, network security is a critical aspect that protects our data and information from unauthorized access. This article covers the basics of network security and some essential practices to ensure a safe online experience.
Key Concepts
- Firewall: Acts as a barrier between a trusted network and an untrusted network, controlling incoming and outgoing traffic.
- Encryption: Converts data into a format that is unreadable without the proper decryption key.
- VPN (Virtual Private Network): Creates a secure and encrypted connection over the internet.
Best Practices
- Use Strong Passwords: Avoid using common passwords and consider using a password manager to securely store your passwords.
- Keep Software Updated: Regularly update your operating system, antivirus software, and other applications to protect against vulnerabilities.
- Use Two-Factor Authentication (2FA): This adds an extra layer of security by requiring a second form of verification, such as a code sent to your phone.
Common Threats
- Phishing: Attempting to obtain sensitive information by posing as a legitimate entity.
- Malware: Software designed to damage, disrupt, or gain unauthorized access to computer systems.
- DDoS (Distributed Denial of Service): Overloading a network or system with traffic to render it unusable.
