🔐 Firewall
A firewall is a critical tool for network security, acting as a barrier between trusted internal networks and untrusted external networks. It monitors and filters incoming/outgoing traffic based on security rules.
🧠 Intrusion Detection System (IDS)
An IDS detects unauthorized access or malicious activities in a network. It can be signature-based or anomaly-based to identify threats.
🧪 Vulnerability Scanner
A vulnerability scanner automatically identifies security weaknesses in systems and applications. Tools like Nessus or OpenVAS are commonly used for this purpose.
🔒 Password Management Tools
Use tools like LastPass or 1Password to securely store and manage passwords. These tools help prevent credential leaks and simplify authentication.
🔒 Encryption Tools
Encryption tools such as OpenSSL or GPG protect data by converting it into unreadable formats. Always use strong encryption protocols for sensitive communications.
