Securing Your Azure Cloud Environment with Application Security Groups (ASGs)
- Azure Application Security Groups (ASGs) provide a powerful solution for securing your cloud environment.
- ASGs allow businesses to define security policies based on application logic and workload. This gives a more granular and efficient approach to managing network traffic.
- ASGs allow you to group resources based on roles and apply security rules at the group level, making it simpler to maintain a robust security posture.
- ASGs allow you to achieve fine-grained control over network traffic, reduce the attack surface and enforce the principle of least privilege.
- ASGs offer enhanced protection of application workloads and create distinct security zones to limit the impact of security breaches.
- When defining security rules for ASGs implement the principle of least privilege, grant only the minimum level of access required for each application component to function properly.
- Regularly review and audit ASGs to ensure ASG configuration aligns with your current application architecture and security requirements.
- Clear naming conventions must be maintained to identify and understand the purpose of each ASG and security rule, reducing confusion and simplifying management tasks.
- ASGs can be easily managed through Azure Portal, Azure CLI, or Azure PowerShell.
- Before diving into the best practices, it's crucial to understand the limitations of ASGs like associating only within the same virtual network (VNet) and having a limit of 3,000 ASGs per subscription.

North Korean hackers have stolen billions in crypto by posing as VCs, recruiters and IT workers
- Security researchers warned at Cyberwarcon, a conference focused on threats in cyberspace, of North Korea’s sustained attempt to steal cryptocurrency and secrets by posing as prospective employees of multinational corporations.
- One of the tactics used by North Korean hackers is to create false identities and masks to hide their IP addresses, disguise their real locations and continue to operate discreetly across the world.
- The cyber attack method used by North Koreans was to create a falsified LinkedIn profile, a GitHub page combined with AI-generated facial and voice-deep learning technology, then link a fake identity with genuine employment credentials.
- Infiltration into remote working at US companies was enabled by home addresses in America run by facilitators that set up farms of company-issued laptops, which include remote access software to allow commands to give the impression that hackers are located in America.
- North Korean groups can extort money from or blackmail companies by threatening to release skimmed sensitive information, establish multiple artificial accounts or backdoor accounts that can evade crucial access controls or dupe banks into laundering Bitcoins.
- Infiltration into industries such as aerospace and defense allowed knowledge necessary to advance further development in the laser-guided missile industry.
- North Korean hackers masqueraded as venture capitalists and recruiters to steal cryptocurrency via malware using an illusory meeting trick to encourage the victim to download ransom-demanding malware.
- Microsoft reported that the North Korean hackers stole $10m in cryptocurrency over a six-month period alone.
- Researchers have called for better background checking of possible employees by companies and recommended companies should introduce two-step verification and should manage company data via cloud-based systems.
- The dangers posed by North Koreans despite sanctions and US-imposed fines have prompted the FBI to warn of the threat while the US government has levied sanctions against North Korean-linked organisations.

Securing IIoT Systems: A Detailed Examination of Major Vulnerabilities and Cybersecurity Threats in…
- The Industrial Internet of Things (IIoT) refers to a network of connected devices, sensors, and machines in industrial environments, facilitating data sharing to enhance operations, boost efficiency, and enable real-time decision-making.
- IIoT systems depend on intricate networks that link numerous devices, sensors, and control systems. This extensive interconnectivity introduces multiple entry points, heightening the risk of exploitation.
- Many IIoT systems still depend on legacy protocols such as Modbus, which were not built to address contemporary cybersecurity threats. These protocols often lack encryption, making them vulnerable to man-in-the-middle attacks, where attackers can intercept and alter the data exchanged between devices.
- Many IIoT devices are designed with limited security features, leaving them vulnerable to exploitation. Devices running outdated firmware or containing security flaws due to poor coding practices can be easily compromised by attackers.
- Data is essential for real-time decision-making, monitoring, and optimization in IIoT systems, making its security critical to the integrity and confidentiality of industrial operations.
- The global scope of IIoT systems often necessitates reliance on third-party vendors for components, software, and services. These dependencies can expose the IIoT environment to security vulnerabilities, highlighting the importance of robust supply chain security measures.
- Cyberattacks represent one of the most significant threats to IIoT systems, with ransomware and malware being two primary forms.
- Insider threats pose a significant risk as well. Employees, whether through malicious intent or negligence, can introduce vulnerabilities into IIoT systems.
- Physical threats are another major concern for IIoT systems. Unauthorized access to critical infrastructure, such as control panels or network devices, can allow attackers to alter system configurations, disable equipment, or install malicious hardware, further compromising security.
- The ISA/IEC 62443 series provides a comprehensive framework for managing cybersecurity risks in IIoT environments, covering everything from secure product development (IEC 62443–4–1) to maintaining the security of operational systems (IEC 62443–3–3).

How to Build a Fortress with the Security of a Tent
- The evolution of APIs calls for a drastically different approach to API security. Token-based architecture is the key to many security issues discussed throughout this presentation, which is increasingly prevalent in a world so widely dependent on cloud-based architecture and microservices.
- APIs are much more widespread than they used to be and are limited to HTTP requests and JSON objects. Instead, APIs are a vital component of single-page applications and mobile applications as well as traditional websites.
- API developers need to ensure these third-party applications interacting with an API are secure, as an API ecosystem is only as secure as its weakest link.
- FAPI is a protocol that requires the use of JSON Web Tokens (JWTs) that enable different access levels, from baseline to advanced profiles and permission granting.
- Sender-constrained tokens tether a user to the mutual TLS connection between the client and the authorization server. The token-handler pattern is a backend for frontend that solves the bulk of the security issues caused by single-page applications and mobile applications by attaching a simple backend.
- Browser-based authorization became popular with the rise of single-page applications and mobile apps. Eliminating the browser from the equation removes virtually all the vulnerabilities.
- To make mobile applications more secure, Jacob Ideskog recommends using a feature called attestation, which uses a mobile device’s hardware chip to validate transactions.
- By implementing the strategies recommended by Ideskog, you can take full advantage of the exploding API market while ensuring business users and customers are secure.
