Security Incident Management
Act Quickly and Limit Damage in the Event of Cyber Attacks
Security Incident Management:
Respond Effectively to Security Incidents
Incident Management Involves Prioritizing, Assessing and Managing Incidents.
Automated processes help security incident management analysts respond optimally to incidents. In the event of an attack, companies must act quickly to minimize damage and contain threats. The foundation for dealing with security-related incidents is the creation of a plan in which tasks and responsibilities are defined. The plan also directs the isolation of malware and affected systems, as well as ensures deeper analysis to identify the attacker and investigate the reason for the attack in more detail.
Why Is Security Incident Management So Important Today?
Companies are regularly attacked by cybercriminals and often suffer long-term damage. With increasing frequency.
We live in turbulent, constantly changing times. The world is networked and digitalization is advancing. We experienced this very clearly in 2020, in particular, when more and more people moved their workplace to a home office. They moved from a network managed by IT professionals to a workplace with no corporate firewalls and possibly no professional antivirus programs protecting them.
This situation makes businesses a sitting duck for cybercriminals and poses major challenges for IT departments.
However, IT security is not just the concern of security specialists; it is also the responsibility of every single employee. Seemingly simply tasks, such as
- Changing passwords regularly,
- sharing confidential information only with known and verified sources,
- updating software,
- regularly backing up data, and
- consistently employing a clean desk / desktop strategy
are an important basis for secure work. Every opportunity should be taken to repeatedly sensitize employees to the topic.
What Should Be Considered When Preparing for Incidents?
The most important thing is to ensure that all employees know their roles and responsibilities in the event of a security incident.
To this end, scenarios can be developed and regularly run through so that they can then be evaluated and optimized, if necessary. A response plan should be well documented, as well as detailing and explaining the roles and responsibilities of everyone involved.
Above all, the competence of each individual counts. The better prepared your employees are, the less likely they are to make critical mistakes.
Answer the following questions for yourself:
- Have employees been trained on the security policy?
- Have the security policies and incident management plan been approved by the appropriate leadership?
- Does the incident response team know its responsibilities and whom to notify?
- Have all members of the team participated in practice drills?
The Incident Management Plan
In cybersecurity, as for ITSM, there are various frameworks, such as ISO 27000 and various NIST specifications. In general, these all recommend the creation of an incident response plan.
An incident response plan is usually a documented set of instructions with multiple phases. The incident response plan defines all necessary actions and clearly outlines responsibilities. It is proven to consist of several phases. Regular reviews of such an incident management plan are necessary.
How can STORM as SOAR software support incident management?
With so many alerts coming in, analysts would waste too much time opening and logging incidents. Instead, a SOAR uses automation to create new cases.
To keep up with the influx of alerts, your cybersecurity team needs an automated solution. SOAR automation quickly prioritizes each incoming case so that critical incidents are responded to first.
SOAR platforms facilitate diagnostics for security analysts by centrally organizing SIEM alerts and other data. This includes WHOIS or MISP information, for example. This means that all data related to a current case is quickly available.
A SOAR solution notifies all stakeholders when an incident occurs: management, dev ops, and IT. Mitigation steps are documented as they happen. Thus, centralized case management in a SOAR solution simplifies the involvement of all responsible parties. Others can immediately see the current progress and status.
Resolution and closure
SOARs document all responses to an incident to prevent future incidents. This documentation cannot be edited. This ensures that the response to an incident is stored in an audit-proof manner.
