Attacker lauren has gained the credentials of an organization’s internal server system, and she was often logging in during irregular times to monitor the network activities. The organization was skeptical about the login times and appointed security professional Robert to determine the issuee. Robert analyzed the compromised device to find incident details such as the type of attack, its severity, target, impact, method of propagation, and vulnerabilities exploited. What is the incident handling and response (IH&R) phase, in which Robert has determined this issues?

Option 1 : Incident triage
Option 2 : Eradication
Option 3 : Incident recording and assignment
Option 4 : Preparation

1. Incident triage

Triage is that the initial post-detection incident response method any responder can execute to open an event or false positive. Structuring an efficient and correct triage method can reduce analyst fatigue, reduce time to reply to and right incidents, and ensure that solely valid alerts are promoted to “investigation or incident” status.

Every part of the triage method should be performed with urgency, as each second counts once in the inside of a crisis. However, triage responders face the intense challenge of filtering an unwieldy input supply into a condensed trickle of events. Here are some suggestions for expediting analysis before knowledge is validated:

  • Organization: reduce redundant analysis by developing a workflow that may assign tasks to responders. Avoid sharing an email box or email alias between multiple responders. Instead use a workflow tool, like those in security orchestration, automation, and response (SOAR) solutions, to assign tasks. Implement a method to re-assign or reject tasks that are out of scope for triage.
  • Correlation: Use a tool like a security info and even management (SIEM) to mix similar events. Link potentially connected events into one useful event.
  • Data Enrichment: automate common queries your responders perform daily, like reverse DNS lookups, threat intelligence lookups, and IP/domain mapping. Add this knowledge to the event record or make it simply accessible.

Moving full speed ahead is that the thanks to get through the initial sorting method however a a lot of detailed, measured approach is necessary throughout event verification. Presenting a robust case to be accurately evaluated by your security operations center (SOC) or cyber incident response team (CIRT) analysts is key. Here are many tips for the verification:

  • Adjacent Data: Check the data adjacent to the event. for example, if an end has a virus signature hit, look to visualize if there’s proof the virus is running before career for more response metrics.
  • Intelligence Review: understand the context around the intelligence. simply because an ip address was flagged as a part of a botnet last week doesn’t mean it still is an element of a botnet today.
  • Initial Priority: Align with operational incident priorities and classify incidents appropriately. ensure the right level of effort is applied to every incident.
  • Cross Analysis: look for and analyze potentially shared keys, like science addresses or domain names, across multiple knowledge sources for higher knowledge acurity.
2. Eradication

Once you’ve contained the issue, you would like to seek out and eliminate the root cause of the breach. this means all malware ought to be securely removed, systems ought to once more be hardened and patched, and updates should be applied.

Whether you are doing this yourself, or rent a 3rd party to do it, you need to be thorough. If any trace of malware or security problems stay in your systems, you will still be losing valuable information, and your liability may increase.

3. Incident recording and assignment

emplates simplify the process of submitting new records by populating fields automatically. A example ensures consistency in the method data about the incident is captured. A record producer may be a specific form of catalog item that allows finish users to create task-based records, like incident records, from the service catalog.

You can use incident templates to quickly create incidents for similar issues.

  • an administrator or user with the template_editor_global role will produce templates that are offered to everyone.
  • an administrator will alter the world option for any personal example that a user creates so that all alternative users will access the example.
  • A user with the itil role will create their own templates for incidents they log frequently.
4. Preparation

Identify employees and outdoors vendors who can handle potential incidents and prepare them for their role in incident response. If a cyber attack were to occur, it’s imperative that responsibilities are clearly defined.

Cybersecurity in many organizations has over the previous few years been exposed as kind of a swiss cheese answer, as cyber criminals have found vulnerable entry points to drag off major hacks costing firms many millions of millions of. In infinite cases, firms have didn’t erect robust defenses, or didn’t acknowledge and quickly react to an attack. Clearly, cybersecurity has to be elevated to the top levels of risk-mitigation strategy, alongside currency risk, natural disaster, and terrorist attacks.
