What do you do if your IT security measures are compromised?

Activate your incident response plan immediately. For instance, if there’s a breach, the first step is to isolate the affected systems to contain the threat.

In the wake of a security breach, quickly identifying the breach's nature and scope is critical. Utilize your incident response team to immediately begin logging all activities, securing evidence for analysis, and considering legal ramifications. Remember, the initial response can greatly influence the outcome of the breach, both legally and operationally.

Determine the extent of the compromise. Look into which systems were affected, the data involved, and whether there is a continuing threat.

In assessing the damage, don't overlook the potential for hidden malware or backdoors left by the attacker. Employ forensic tools to analyze breach points and affected systems comprehensively. This detailed assessment aids not only in understanding the attack's impact but also in preventing future vulnerabilities.

Prepare to manage public perception and stakeholder confidence carefully. Offering clear, concise, and regular updates about what is known, what is not known, and what steps are being taken can help manage the situation more effectively.

Inform all stakeholders transparently about the breach’s scope and the steps being taken, following regulatory requirements. PRO should act as a single point of contact for any statement/news issued in Public about the incident.

Prioritize the restoration of critical systems first but do so after ensuring they are thoroughly cleaned and secured. This phased approach to restoration helps in minimizing operational downtime while safeguarding against further breaches.

Few steps to follow - Patch vulnerabilities to stay up-to-date Enhance security features Change default credentials Enforce strong passwords- Set up monitoring to detect compromised credentials. Implement more effective controls

Conduct a thorough post-incident analysis to identify lessons learned and integrate them into your security strategy. Continuous improvement will make your defenses stronger and more resilient. For example, after a phishing attack breaches a company’s email system, they would follow these steps, ensuring to revise their security training to include the latest phishing tactics.
