This calls for an understanding of the devices and technologies within the network, as network devices will generate different types and amounts of traffic. Incident responders should be able to determine the normal bandwidth of these devices in order to tell whether a breach has been suffered or not. Incident responders should be aware of normal and abnormal traffic emanating from them and be able to classify the risk. When I work with my team I believe it is as important to lead as well as dig in when necessary.
Analyzing vast amounts of network traffic can be strenuous, so an understanding of automation is also important: it greatly reduces the effort that goes into responding to incidents. There are a couple of steps that incident responders can take to mitigate against network-based attacks:. Incident responders should also be aware of common technologies used within organizations such as Active Directory AD and how a properly configured AD should look.
Most attacks target such commonly used technologies. Incident responders need to be able to make use of packet capture and analysis tools. These tools can help incident responders capture and analyze traffic. The following are some of the tools that incident responders should be familiar with:. The tools above are not the only available ones. However, the familiarity of these tools can greatly assist in how one executes incident response.
Some of these tools are open-source, while others are commercial. The NHS Wales Cyber Resilience Unit will establish a triage system of determining the severity and impact of the reported incident, which will assist in the categorisation of the incident.
This may include requesting further details of the incident. The purpose of these assessments could be to:. This could be:. The NHS Wales Cyber Resilience Unit and Welsh Ministers will maintain a confidential register of reported incidents which will include whether or not an investigation took place, and the outcome of any investigation.
It is important to note that simply having an incident is not in itself an infringement of the NIS Regulations and therefore does not automatically mean enforcement action will be taken. The key factor for determining whether enforcement action should be taken when there has been an incident, is whether or not appropriate and proportionate security measures and procedures were in place and being followed.
Competent Authorities are required to monitor the application of the NIS Regulations with operators of essential services, which includes monitoring whether OES are meeting their security duties. This will be done through assessing the level of compliance of OES against the security requirements set out in this document.
This role must be fulfilled through a proactive approach which specifically includes direct engagement with OES, publishing guidance such as this document and implementing an assessment framework to check compliance with the security requirements which includes an audit regime.
Therefore, it is Welsh Ministers policy to only use their power to inspect where the NHS Wales Cyber Resilience Unit is unable to obtain sufficient information from an operator of essential services, or in response to a specific concern.
Compliance should be assessed against the fourteen NIS security principles at Annex 1. To ensure an appropriate and proportionate approach each health organisation will be assessed independently against the Cyber Assessment Framework CAF for Health in Wales link at Annex 2.
The applicability of each step will be discussed and agreed with a health organisation during the initial engagement step and determined based on several factors including the assessment of cyber security risk, health organisation complexity, and regulatory requirements.
Using the provided Critical System Scoping template and Guidance, each OES must determine and document all critical systems in scope of the relevant safety, security, or resilience regulation s for the health sector. This may include systems and services operated on behalf of the OES by third party suppliers. Welsh Ministers and the Cyber Resilience Unit understand that this regulatory landscape is an emerging and fast-moving area, and recognise the challenging constraints that health organisations currently operate within.
As such, a decision has been taken to operate a tiered approach to compliance that ensures fairness and promotes continual improvement towards conformance with the CAF for Health in Wales. Assessments are to be carried out on an annual basis, although in the event of deficiencies more frequent assessments may be undertaken. Beyond the first year, the NHS Wales Cyber Resilience Unit and Welsh Ministers will use the results of the self-assessment, along with threat and vulnerability information, to establish a risk-based programme of ongoing activity including audits as described above to monitor compliance.
Simply having a cybersecurity incident is not by itself an infringement of the NIS Regulations; the key factor for determining enforcement action is whether or not appropriate and proportionate security measures and procedures were in place and being followed. Steps organisations have taken to improve their cyber resilience will be a significant factor in determining the level of enforcement issued. Welsh Ministers will use a stepped approach to enforcement when an OES is found to be failing to meet requirements.
Any enforcement, particularly the issuing of penalties, will be a last resort and in all cases will be proportionate to the failing identified. The stepped approach that Welsh Ministers will take in the Health Sector in Wales is summarised below:. Financial penalties which can be applied are:. Whilst any enforcement action will be proportionate, Welsh Ministers will use their full range of enforcement powers where sufficient action is not being taken by operators. This will apply not just to GDPR but other sectoral and general legislation.
However, the NIS Regulations make provision for Competent Authorities to consider whether enforcement action is reasonable and proportionate on the facts and circumstances of the case, including consideration of whether a contravention is also liable to enforcement under another enactment. Operators of Essential Services have the right to appeal to a First-Tier Tribunal against one or more of the following decisions of Welsh Ministers:.
The first-tier tribunal must determine the appeal after considering its grounds and by applying the same principles as would be applied by a court on an application for judicial review. Email: HSS. CyberReporting gov. Each principle describes mandatory security outcomes to be achieved.
The full guidance collection on the NCSC's website see Annex 2 goes into further detail on each principle with references to a range of existing guidance and standards. Appropriate organisational structures, policies, and processes are in place to understand, assess and systematically manage security risks to the network and information systems supporting essential services. Putting in place the policies and processes which govern your organisation's approach to the security of network and information systems.
Identification, assessment and understanding of security risks. While the description of the condition field claims that it contains only Boolean logic for combining strings, its true functionality is much more powerful. Among other things, YARA rules can count the occurrences of a string within a sample and look for strings at specific offsets. This functionality makes YARA rules much more powerful and enables the creation of complex rules that will only match the true sample of interest and dramatically reduce false detections.
Wireshark is primarily designed for detection of malicious files, but it can also be a powerful tool for network traffic analysis in incident response. ChopShop is an open-source tool developed by MITRE that has the ability to reassemble network flows and apply YARA signatures to the results, dramatically improving the ability of the signatures to match samples that may be fragmented over multiple packets. Event-based analysis is an extremely valuable tool for incident response because it helps to solve one of the biggest challenges of IR: knowing where to look.
Incident responders commonly need to sift through massive amounts of data in order to identify the particular features that point to the type and scope of an incident that the organization is experiencing. Event-based analysis is the easiest to automate, and many solutions like Snort and Suricata exist to do so, allowing the analyst to focus their efforts on the data most likely to be of interest. The main challenges of event-based analysis for IR are based upon the need for a signature in order to perform analysis.
Since an incident responder needs to be able to define a certain type of event in order to search for it in this way, they are limited to the types of incidents that they know about and can define. This is why event-based analysis is increasingly being used in conjunction with statistical analysis and machine learning: event-based analysis finds the known attack types and the other analysis techniques point to anything else. Between them, they have the potential to dramatically reduce the search space for analysts and massively improve the probability of a speedy detection of and response to an incident.

The Commission should periodically review this Directive, in consultation with interested stakeholders, in particular with a view to determining the need for modification in the light of changes to societal, political, technological or market conditions. The sharing of information on risks and incidents within the Cooperation Group and the CSIRTs network and the compliance with the requirements to notify incidents to the national competent authorities or the CSIRTs might require processing of personal data.
Since the objective of this Directive, namely to achieve a high common level of security of network and information systems in the Union, cannot be sufficiently achieved by the Member States but can rather, by reason of the effects of the action, be better achieved at Union level, the Union may adopt measures, in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty on European Union.
In accordance with the principle of proportionality as set out in that Article, this Directive does not go beyond what is necessary in order to achieve that objective. This Directive respects the fundamental rights, and observes the principles, recognised by the Charter of Fundamental Rights of the European Union, in particular the right to respect for private life and communications, the protection of personal data, the freedom to conduct a business, the right to property, the right to an effective remedy before a court and the right to be heard.
This Directive should be implemented in accordance with those rights and principles,. This Directive lays down measures with a view to achieving a high common level of security of network and information systems within the Union so as to improve the functioning of the internal market. Without prejudice to Article TFEU, information that is confidential pursuant to Union and national rules, such as rules on business confidentiality, shall be exchanged with the Commission and other relevant authorities only where such exchange is necessary for the application of this Directive.
The information exchanged shall be limited to that which is relevant and proportionate to the purpose of such exchange. Such exchange of information shall preserve the confidentiality of that information and protect the security and commercial interests of operators of essential services and digital service providers. This Directive is without prejudice to the actions taken by Member States to safeguard their essential State functions, in particular to safeguard national security, including actions protecting information the disclosure of which Member States consider contrary to the essential interests of their security, and to maintain law and order, in particular to allow for the investigation, detection and prosecution of criminal offences.
Where a sector-specific Union legal act requires operators of essential services or digital service providers either to ensure the security of their network and information systems or to notify incidents, provided that such requirements are at least equivalent in effect to the obligations laid down in this Directive, those provisions of that sector-specific Union legal act shall apply.
Without prejudice to Article 16 10 and to their obligations under Union law, Member States may adopt or maintain provisions with a view to achieving a higher level of security of network and information systems.
