More about this course

Our SSL/TLS training course is focused on the tools and practical techniques needed by Engineers who work with SSL. It is led by an expert instructor who will guide you through Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), both of which are cryptographic protocols designed to provide communication security over a computer network. 

Additionally public key infrastructure (PKI) will be covered in some detail to help you create, manage, distribute, use, store, and revoke digital certificates.

The course is very much run as a hands-on workshop with an emphasis on practical issues you can expect to encounter and how to properly check for these.

To enable this, delegates will be exposed to a broad range of tools available to those working in this field.

FAQs

JBI Training offers a broad range of cyber security and application security courses covering both technical and managerial disciplines. Available courses include Threat Modelling for Developers, Secure Web Application Development, OWASP Top 10 Practical Web Application Security, TLS and PKI in Practice, Secure Coding for Java and JavaScript, Secure Coding in ASP.NET, Secure Coding in PHP, Security for Python, Secure by Design, Post Quantum Cryptography, Social Engineering, Information Security, Cyber Attack Simulation, PCI DSS Compliance, CISSP, CISM, CISA, Certificate of Cloud Security Knowledge (CCSK), and Certificate of Cloud Auditing Knowledge (CCAK). All courses are available as scheduled classroom sessions in London, as live online instructor-led training, or as customised onsite programmes for development and security teams.
Threat modelling is a structured process used to identify security weaknesses in software design and architecture before any code is written. It involves creating an abstraction of the system, profiling potential attackers and their methods, and producing a catalogue of threats so that countermeasures can be defined and prioritised early in the development lifecycle. It is particularly important for developers and architects because it identifies design flaws that code reviews and testing alone may miss, reduces the cost of remediation by detecting issues before deployment, and integrates naturally into Agile and DevOps workflows. JBI's Threat Modelling for Developers course is language-agnostic and suitable for teams working with any modern development process.
The OWASP Top 10 is a widely recognised list of the most critical security risks to web applications, published by the Open Web Application Security Project. It covers vulnerabilities such as injection attacks, broken authentication, insecure design, security misconfigurations, vulnerable components, and others that are commonly exploited in real-world attacks. JBI offers a dedicated OWASP Top 10 Practical Web Application Security course, and OWASP principles are also embedded in the Secure Web Application Development and Threat Modelling courses. These courses are suitable for developers, security engineers, and QA professionals who need to understand and address common web application vulnerabilities.
Yes. A significant part of JBI's security curriculum is specifically designed for developers and software engineers rather than for dedicated security professionals. Courses such as Threat Modelling for Developers, Secure Web Application Development, Secure Coding for Java and JavaScript, Secure Coding in ASP.NET, Secure Coding in PHP, and Security for Python are aimed at development teams who need to build security into their code and architecture from the outset. These courses can be delivered as customised onsite programmes for software teams, tailored to the languages, frameworks, and development processes the team already uses.
JBI offers preparation courses for several internationally recognised security certifications. These include CISSP (Certified Information Systems Security Professional), CISM (Certified Information Security Manager), CISA (Certified Information Systems Auditor), Certificate of Cloud Security Knowledge (CCSK), and Certificate of Cloud Auditing Knowledge (CCAK). These courses are designed to prepare candidates for their respective examinations and are suitable for information security managers, auditors, risk professionals, and senior technical staff who want to demonstrate formal competence in information security management and cloud security.
Post Quantum Cryptography (PQC) refers to cryptographic algorithms designed to be resistant to attacks from quantum computers, which are expected to eventually break many of the encryption standards currently in use — including RSA and elliptic curve cryptography. Organisations in finance, government, defence, and critical infrastructure are beginning to assess and plan their migration to quantum-resistant algorithms in response to guidance from standards bodies including NIST. JBI's Post Quantum Cryptography course covers the threat landscape, the current state of quantum computing, the new PQC standards, and practical approaches to transitioning cryptographic infrastructure.
The Secure by Design course covers the principles and practices of building security into software and systems from the earliest stages of design, rather than adding it as an afterthought after development. Topics include security architecture patterns, design principles such as least privilege and defence in depth, risk-based design decisions, integrating security requirements into user stories and system specifications, and applying secure design thinking within Agile and DevOps environments. The course is aligned with current guidance from bodies including NCSC (National Cyber Security Centre) and is relevant for architects, senior developers, and technical leads.
Yes. All of JBI's security courses can be delivered as customised onsite or online programmes for corporate teams. Content can be tailored to the organisation's technology stack, development language, industry sector, compliance requirements, and security maturity level. JBI has delivered security training for organisations across financial services, healthcare, government, media, and technology, including clients such as the BBC, NHS, Cisco, RBS, and Capita. Organisations with specific regulatory or compliance obligations — such as PCI DSS, GDPR, or sector-specific frameworks — can request content that addresses those requirements directly.
TLS (Transport Layer Security) is the protocol used to encrypt data in transit across networks, and is the technology behind HTTPS and secure communications in modern applications. PKI (Public Key Infrastructure) is the framework of certificates, certificate authorities, and key management processes that underpin TLS and other certificate-based security mechanisms. JBI's TLS and PKI in Practice course covers how these technologies work in real deployment scenarios, common misconfigurations and vulnerabilities, certificate lifecycle management, and practical implementation for developers and infrastructure teams. This is particularly relevant for organisations managing APIs, microservices, internal networks, or customer-facing web applications.
Yes. JBI's security training content is continuously reviewed and updated to reflect the latest threat landscape, newly published vulnerabilities, updated standards, and current regulatory guidance. This includes updates to OWASP guidance, changes to cryptographic standards, emerging attack techniques such as AI-assisted social engineering and supply chain attacks, and the latest PQC standards from NIST. Delegates learn skills and concepts that are directly applicable to the security challenges organisations face today.
