National Cybersecurity Awareness Month: Incident Response
The theme for this year’s National Cybersecurity Awareness Month (NCSAM) is “Own IT. Secure IT. Protect IT”. With[…]
Incident response is an approach to review, and respond to a cyber security breach or attack utilizing a planned process or methodology.
Effective incident response teams utilize procedures and technology, such as automated playbooks, to respond quickly and adequately to cyber security events, limiting the damage done by attackers.
During an incident investigation security analysts assess different indicators of compromise (IoCs) or the tactics, techniques, and procedures (TTPs) of an attack to determine the context in which an alert is firing. We look at how you can find critical information that will help gain a true understanding of the alert or incident.
On average, the mean time to identify a security breach is 197 days or approximately 28 weeks, according to IBM Security. Incident handlers need to prioritize the information that is communicated to executives and speak to what executives are most concerned about.
The context for security events is a key factor for investigation and remediation. This begins with understanding what is normal for each user or entity in the organization. Exabeam models user activity to build this baseline of normal and score risk based on anomalies – not artificial correlations.
The right mix of IR automation and IT orchestration can drastically cut the time analysts spend on manual steps—often from many days to mere minutes. While far from being a silver bullet, automation and orchestration are proven approaches to improving the security, efficiency, cost, and morale of security teams and organizations that depend on them.
A security incident is often a high-pressure situation. Having pre-planned incident response steps helps for an immediate and more organized response and can spare many unnecessary business impacts and associated reputational harm.
