Time is critical.
“Effective methods for detecting and responding to security incidents are essential for a mature cyber security methodology, but organisations can find this extremely challenging to achieve.
During recent years, organisations have improved their ability to self-detect security incidents through the multitude of tools available in the market, but the average time taken from initial occurrence to detection is still measured at anything between 66 and 90 days.”

The earlier an incident is detected, the more forensic data is available, which can accelerate the identification of what has occurred, containment of the incident, and restoration of services to normal.
The incident response timeline to the right shows the mountainous challenge that organisations face.

When detecting and responding to cyber incidents, there are a number of common challenges that businesses face, but there are ways to approach and mitigate them.
Cyber threats can be complicated and, in some cases, take advantage of software vulnerabilities that are difficult for us to understand, let alone isolate and remediate after a breach. Whilst there are also many incidents that take advantage of simple human error through phishing or malware attacks, organisations often suffer from a lack of the specialist skills and experience that are required to mitigate the effects of these incidents quickly and confidently.
Investing in your existing people and allowing them to learn and prosper with a fully interactive, gamified, and on-demand training program can help them to hone their skills in the latest real life Cyber threats in safe lab environments. They will stay up to date with the latest risks and learn how to tackle them confidently.
It’s not possible for security teams to fully analyse a security incident and carry out effective incident response if there are gaps in the forensic information available to them. However, the levels of log and alert information required to eliminate these gaps can leave IT security teams overwhelmed by a huge number of alarms, creating a difficult and laborious task of identifying and correlating malicious vs false positive events.
Security Orchestration, Automation, and Response (SOAR) tools can help you to get on top of this problem. By utilising machine learning intelligence, a SOAR solution makes it possible to automate the previously repetitive and time-consuming job of sifting through the logs and separating the good from the bad. Consequently, your team can minimise response times when an incident occurs, getting to the crux of the issue quicker rather than being bogged down by manual tasks.
Some security threats are predictable whilst others are unique, but what is common is that effective incident response requires a structured and focused process.
Creating a set of Playbooks in the organisation provides a step-by-step checklist of actions to follow in the event of a security incident, allowing everyone to know what part they play. Playbooks offer a guided approach, allowing all areas of the business to quickly and efficiently respond to security breaches. Streamlined processes and workflows ensure that the organisation can first resolve the incident, and then restore services as quickly as possible, whilst adhering to any regulations for data breach notification and reporting.
Each year, global legal firm BakerHostetler analyse the data from incidents they helped companies manage over the previous year. In their Data Security Incident Response report BakerHostetler discuss the insights gained from working on more than 750 incidents in 2018.

What is SOAR in relation to SIEM?
SOAR and SIEM are both security tools designed to aid SOC (Security Operations Centre) teams, offering increased efficiency in monitoring and response. SIEM provides valuable data collection and analysis, however some SIEM solutions tend to produce many alerts that can increase the complexity and workload for SOC staff. SOAR tools are available to augment the capabilities of SIEM solutions, combining user and entity behaviour analytics (UEBA) and automation to analyse SIEM data and deliver effective investigation and response.
