Training location: Lõõtsa 12, Tallinn (Training is held in English)

Goals: to clarify various configuration security issues and practical aspects on hardening services.

Training in a nutshell: Service Hardening is about configuring services to reduce their attack surface. By combining various low priority configuration issues, an attacker may be able to gain access and even elevate in a system without leaving much traces behind. Training focuses on practices that can be applied to almost any service – without modifying the program code.

Keep in mind that hardening reduces attack surface, it does not make a system secure!

 

Target audience: developers, administrators, testers, security incident handlers and

anyone else who has to deal with creating or maintaining services.

 

The main topics covered are:

• Certificates - chain verification, extended key usage, status, transparency, CAA
• TLS - protocol versions, cipher suites, forward secrecy, CCA
• SSH - host keys and SSHFP, agent forwarding
• E-mail - DKIM, SPF, DMARC
• DNS - DoT/DoH, DNSSEC
• Logging - log tampering, creating meaningful logs

For each topic, first the theory is explained, based on this, the student will attack a service in a lab environment and finally, the student will harden that service to withstand such attack.

 

The results of the training:

• The main outcome is to help trainees understand different possible attacks that can be conducted towards services with default configuration.
• How to defend themselves against such threats and also the importance of logging certain data, so that resulting logs would be most beneficial when solving possible security incidents.
