Unix protection

OpenSSL

Overview: OpenSSL is a cryptographic library that provides secure communication over a network.

Key Features:

• Encryption: provides encryption algorithms such as AES, RSA, and SHA
• Secure Sockets Layer/Transport Layer Security (SSL/TLS): implements SSL/TLS protocol for secure communication
• Digital Certificates: generates and manages digital certificates for authentication
• Random Number Generation: generates random numbers for cryptographic purposes

OpenSSH

Overview: OpenSSH is a secure remote access tool that provides secure shell access to Unix systems.

Key Features:

• Secure Shell (SSH): provides secure shell access to Unix systems
• Encryption: encrypts data transmitted over the network
• Authentication: supports various authentication mechanisms, including passwords, public keys, and Kerberos
• Tunneling: allows for secure tunneling of TCP connections

Snort

Overview: Snort is an intrusion detection system (IDS) that monitors network traffic for suspicious activity.

Key Features:

• Real-time Traffic Analysis: analyzes network traffic in real-time
• Rule-based Detection: uses rules to detect known attacks and anomalies
• Protocol Analysis: analyzes network protocols, including TCP, UDP, and ICMP
• Alerting: generates alerts for detected suspicious activity

Tripwire

Overview: Tripwire is a file integrity monitoring tool that detects changes to system files and data.

Key Features:

• File Integrity Monitoring: monitors system files and data for changes
• Real-time Alerting: generates alerts for detected changes
• Policy-based Configuration: allows for policy-based configuration of monitoring rules
• Compliance Reporting: provides compliance reporting for regulatory requirements
