NIS2: 1. Perform a gap analysis

We wrote here https://www.sorinmustaca.com/how-to-nis2-eu-directive/ that the first step in implementing NIS2 requirements is to perform a gap analysis.   The most critical part when performing a gap analysis is to define upfront against which standard or security framework are you comparing the existing situation. It is usual when performing a gap analysis of security maturity to compare against ISO 27000 standard, the ISO 27001 in particular. Performing a gap analysis on the security stance of a company following ISO 27001 involves comparing its current security measures and practices against the requirements specified in the ISO 27001 standard. This analysis helps identify areas where the company’s security posture aligns with the standard (compliance) and areas where there are gaps or deficiencies (non-compliance). Here’s a technical breakdown of the process:   Familiarize with ISO 27001 Understand the ISO 27001 standard and its security requirements. This includes studying the Annex A controls, which represent a comprehensive set of security best practices. Define the Scope Determine the scope of the analysis, starting with which areas of the organization’s security management system (SMS) will be assessed, such as specific departments, processes, assets, or locations. Then focus on which parts of the company’s operations will be…

How-To: NIS2 EU Directive

The NIS2 Directive is a European Union legislative text on cybersecurity that supersedes the first NIS (Network and Information Security) Directive, adopted in July 2016. NIS vs. NIS2 While the first NIS (Network and Information Security) Directive increased the Member States’ cybersecurity capabilities, its implementation proved difficult, resulting in fragmentation at different levels across the internal market. To respond to the growing threats posed with digitalisation and the surge in cyber-attacks, the Commission has submitted a proposal to replace the NIS Directive and thereby strengthen the security requirements, address the security of supply chains, streamline reporting obligations, and introduce more stringent supervisory measures and stricter enforcement requirements, including harmonised sanctions across the EU. NIS2 strengthens security requirements in the EU by expanding the NIS scope to more sectors and entities, taking into account the security of supply chains, streamlining reporting obligations, introducing monitoring measures, introducing more stringent enforcement requirements, adding the concept of “management bodies” accountability within companies, and harmonizing and tightening sanctions in all Member States. To achieve the above mentioned goals, NIS2 requires member states to take a number of measures that forces them to work together: Establish or improve information sharing between member states and a common incident…

How to convince Top Management to invest in cybersecurity and secure software development

I’ve heard many times IT people and Software Developers complaining that they have difficulties to sensibilize their managers to invest more in cybersecurity. Also some employees of my customers in the cybersecurity consulting area show sometimes frustration when we are talking about priorities of their top management – cybersecurity is almost neveve one until it is too late. When I talk to C-Level of the organizations that book us for consulting, I am telling them that organizations face an increasing number of cyber threats these days compared to 10-20 years ago  (yes, we are so old). They have a lot of risks like data breaches, ransomware attacks, and intellectual property theft and their only chance to survive these is to  investing early in robust cybersecurity measures and secure software development practices. However, convincing top management to allocate resources and invest in these areas is a challenging task for everyone, me included. Unfortunately, investing in cybersecurity is a bit like investing in a optional insurance: you want it so that you can stay relaxed, but you know you are not forced to buy it, so you try to find the cheapest one that covers more or less your risks. Additionally, you…
