• Real-life Example: Setting up alerts for any unusual or suspicious SSH activity in a cloud backup and recovery system.
• Takeaway: Auditing and monitoring SSH activity provides valuable insights into potential security breaches and enhances incident response capabilities.

Main Point 7: Ignoring SSH hardening guidelines

• Following SSH hardening guidelines helps protect against security vulnerabilities and unauthorized access attempts.
• According to the CIS Benchmarks, SSH protocol weaknesses are common targets for attackers.
• Implementing SSH hardening measures improves overall security posture and reduces the attack surface.
• Mistake: Ignoring or neglecting established SSH hardening guidelines.
• Actionable Tip: Adopt SSH hardening best practices provided by reputable sources, such as CIS Benchmarks.
• Real-life Example: Applying recommended SSH hardening configurations and settings to a cloud backup and recovery environment.
• Takeaway: Following SSH hardening guidelines enhances the security of cloud backup and recovery systems.

Main Point 8: Failing to enforce SSH session timeouts

• Enforcing SSH session timeouts is crucial for preventing unauthorized access and reducing the risk of session hijacking.
• The increased prevalence of remote working has amplified the importance of session timeouts for secure access.
• Session timeouts automatically terminate idle SSH sessions, mitigating the risk of unauthorized access.
• Mistake: Not implementing SSH session timeouts or setting excessively long timeout periods.
• Actionable Tip: Configure SSH session timeout limits based on user requirements and security considerations.
• Real-life Example: Setting session timeouts to 10 minutes for SSH connections in a cloud backup and recovery setup.
• Takeaway: Enforcing SSH session timeouts improves security by automatically ending idle or unattended SSH sessions.

Main Point 9: Overlooking SSH firewall and network configuration

• Configuring SSH firewalls and networks properly is essential for securing SSH connections and preventing unauthorized access.
• According to a study by the CERT Coordination Center, SSH is often misconfigured, leaving it vulnerable to attacks.
• Proper SSH firewall and network configuration enables restricted access and controls network traffic effectively.
• Mistake: Neglecting to configure SSH firewalls and networks with security in mind.
