How can you report a security incident effectively?

Start by clearly identifying the incident type (e.g., data breach, malware infection, unauthorized access). Detail the symptoms and evidence that led to the identification, such as unusual system behavior or unauthorized data access alerts. This precise description helps in categorizing the incident for appropriate response actions. For more in-depth guidance, the National Institute of Standards and Technology (NIST) offers a comprehensive guide on handling incidents, available at their website.

It is important to differentiate between information gathering for triage and forensic analysis. During the triage phase, the focus must be on identifying and analysing the key pieces of information to contain the incident. As logs can be overwritten, it is also important to make copies of them for forensic analysis later. Analysts can sometimes form an opinion and then look for evidence to support that point of view so, challenging assumptions is also an important step during this stage.

?? Effective security incident reporting is key! Here’s how: 1?? Act Immediately: Time is of the essence. Report as soon as you detect a potential security threat. 2?? Detail Matters: Include specific details like what was observed, the time, and the impact. 3?? Use Proper Channels: Report through the designated incident reporting system or to the designated security contact. 4?? Follow Up: Stay engaged to provide any additional information and to learn from the incident. Quick, detailed, and through the right channels makes all the difference! ?

Il me semble qu’en fonction de la gravité de l’incident il y a des mesures de sauvegarde des personnes et des biens qu’il faut engager immédiatement. Ces éléments sont habituellement décrit dans des documents de référence SSE ou Qualité Certains cas nécessitent de prévenir immédiatement des services gouvernementaux… ce qui conduit dans ce cas à perdre une bonne partie des pouvoirs de décision sur la suite des événements

It's important to distinguish whether what happened was truly an incident (data spillage, bringing a PED into a secure are, etc.) or an infraction (poor security practice that could lead to an incident). Understanding that will better guide the security team in a response. Knee-jerk reactions can often cause more harm to operations than the initial problem so details are EXTREMELY important. Once you've binned the incident into a particular category (personnel-related, physical security, industrial security, etc.), then you can move forward with the rest of the damage mitigation process while minimizing impact to the rest of the team and organization.

When notifying stakeholders about a security incident, prioritize clear, concise communication. Include the incident's nature, the affected systems or data, and the immediate steps taken to mitigate the risk. Avoid technical jargon to ensure all stakeholders, regardless of their IT proficiency, understand the message. It's crucial to inform them about potential impacts and any actions they may need to take.

As a user, Notifying the relevant stakeholders (Cyber Security Ops team) is the best things that we can do. As a Cyber Security specialist, it is important to devise algorithms to identify the threat, notify the stakeholders (impacted user(s), peers, top management), identify root cause, implement Corrective Action and Preventive Action (CAPA), be on the watch out. It is a continual cycle like DMAIC (Define, Measure, Analyze, Improve, and Control)

How you notify stakeholders can also be an important consideration. You can actually make a problem worse by reporting it the wrong way. It's one thing to email the helpdesk to say you accidently clicked on a suspicious link. It's something completely different to send an email that a contractor accidently sent an unencrypted data file via email including the financial data for all your high net worth clients. Some things require extra discretion since disclosure of the event may do more damage than the event itself. Try to report the incident verbally or at least securely to contain the event.

The information collected during the triage phase is used first to contain the incident. There is a significant difference between post-incident review and analysis during the containment phase. Analysis during the containment phase is conducted to identify the extent of the damage and the actions required to contain the incident. It is worth highlighting the importance of conducting the analysis on copies of original data, making copies of things like memory and log files that can be overwritten and maintaining a chain of custody for information that may be presented in a court of law.

Il n’y a pas de raison de penser que l’incident est circonscrit à une problématique purement IT … Certains incidents peuvent insidieusement avoir des effets sur des équipements ou sur des consignes de fonctionnement… certains effets peuvent se constater très tardivement. C’est la raison pour laquelle il faut bien conna?tre les liens entre les systèmes et entre les équipements et les systèmes ..

Il n’y a pas de raison de se limiter à des sujets de communication..d’ailleurs il est assez rare qu’une communication large des incidents soit réalisée … au motif qu’elle peut avoir des répercussions sur l’entreprise elle même. Les éléments de communication sont souvent mentionnés dans des manuels de crise ou des procédures extrêmement précises

1. Immediate Response : - Act Quickly : Start reporting as soon as you detect the incident to limit damage. - Containment : Immediately work to contain the breach. 2. Document the Incident : - Incident Details : Note what happened, when, how it was discovered, and what was affected. - Initial Actions : Log initial containment efforts. Best Practices: - Clarity : Be clear and concise. - Confidentiality : Maintain privacy of sensitive info. - Policy Adherence : Follow your organization's response and reporting protocols. - Continuous Improvement : Use incidents as learning opportunities to bolster security.
