Cyberattacks are like snowballs rolling down a hill; they tend to start small. Unfortunately, too few businesses have the right resources or processes in place to fully mitigate these threats before they proliferate. And when cyberattacks are allowed to snowball from minor incidents into major business risks, they can have devastating consequences. Research shows that it takes companies 128 days on average to detect a breach. That’s four months, during which an attacker can steal data, damage your systems and disrupt your ability to do business.
Security incident response (SIR) is designed to help organisations respond to these kinds of network intrusions before they impact their business. Structured to handle many kinds of cyberthreats and security incidents, SIR establishes proven and scalable workflows and procedures that security operation centres (SOC) and incident response teams can use to minimise impact on the business and reduce recovery times.
Just like the snowball that grows as it goes, unaddressed and uncontained security incidents will almost always escalate. This can mean everything from lost user credentials and compromised company and customer data, to expensive and reputation-damaging down time, to total system collapse. Security incident response empowers SOC teams with the correct resources, tools and processes to locate and prioritise those security incidents before they have the chance to start rolling.
By establishing best practices, automated and collaborative workflows and step-by-step threat mitigation plans that cover each phase of threat response, SIR exists to stop intrusions as quickly as possible and to provide companies with proven and scalable response strategies for recovering quickly after the breach has been contained and eliminated.
In addition to ensuring a fast recovery from potential data-breach events, security incident response helps companies meet regulatory compliance standards, such as those required by law within sectors such as healthcare and financial services. Finally, SIR protects brand reputation that might otherwise suffer permanent damage as a result of a successful breach.
For security incident response to be effective, it must be fully prepared and ready to implement long before the security incident in question ever occurs. A security incident response plan (SIRP) is a formal, official set of documentation that clearly details the actions that must be taken at every stage of a company’s security incident response. At the same time, the SIRP should outline security-response roles and responsibilities throughout the organisation and address how these roles should communicate and interact within established response protocols.
Because the SIRP is designed for fast deployment during the most critical early hours of an attack, it must be clear, unambiguous in terminology and language and easy to follow. SIRPs often include or reference a library of incident response playbooks.
At its most basic, a SIRP is a set of directions for response teams to follow, allowing them to identify threats, respond effectively and reduce the impact of the security incident overall with speed and accuracy.
Because there is so much riding on how rapidly a company can deploy their response strategy, most SIRPs follow an established format consisting of six key stages:
As security threats continue to grow in frequency, complexity and sophistication, security incident response has gone from competitive differentiator to essential security standard. But when every second counts, security teams are discovering that they simply do not have the power to fully investigate, verify and respond to every possible security incident as it occurs. Service Now provides the solution.
ServiceNow Security Incident Response transforms the standard approach to IT Security investigation, response and recovery, by applying advanced automation capabilities and centralising security operations data, insights and reporting on a single platform. Empower and scale response teams with automated prioritisation, triage, data analysis and other essential response tasks. Then take things further with real-time insights, detailed playbooks and full network security visibility.
