What is Digital Forensics and Incident Response (DFIR)?

As a highly specialized branch of cybersecurity, digital forensics and incident response (DFIR) plays a crucial role in determining the impact of a cyberattack and conducting a thorough investigation — all while it is happening. It involves a forensic process conducted by seasoned digital security experts and a simultaneous process that handles attack containment and recovery of normal business operations. The insights gained from DFIR investigations often serve as evidence in legal proceedings against the perpetrators.

The Importance of DFIR

Every day, the methods and tactics of cyberattackers grow in sophistication. So do the security tools used for preventing those cyberattacks. Given this relentless arms race, a common consensus among cybersecurity experts is that becoming the victim of a cyberattack is not a matter of if , but when. Even software companies with world-class technical staff on their payroll have suffered serious breaches. The immediate aftermath of a cyberattack presents one of the most challenging periods for a company and its entire workforce. The outcome of the attack directly impacts the future of the company. This is where the techniques of DFIR prove their value. DFIR empowers organizations to respond to and recover from cyber incidents and gather comprehensive digital evidence to deepen their understanding and learn from the attack. By allowing organizations to meticulously investigate breaches, preserve digital evidence, and piece together the puzzle left by cyber criminals, the capabilities of DFIR enable companies to strengthen their defenses while relentlessly working to restore IT systems to their normal state.

Considerations when choosing a DFIR tool

When choosing a DFIR solution, understanding the specific nature of this field is important. Although many DFIR tools are used to prevent attacks proactively, they are also used after a security incident has already occurred — a time when rapid response is crucial for containing the damage. With this in mind, let’s consider the following list of key DFIR features:

Support for a variety of data sources

Confirm that the DFIR tool is compatible with the types of data sources and platforms used in your organization. This includes support for various operating systems, file formats, and devices (including mobile devices). This support allows you to cover a broad range of potential evidence sources.

Support for a wide range of deployment options

Organizations have different requirements for data privacy and regulatory compliance. The flexibility in deployment capabilities allows you to configure a setup that aligns with your specific privacy and compliance needs while seamlessly scaling when required.

Data integrity and legal compliance

Data integrity is crucial. Many industries are subject to data protection laws and regulations, such as GDPR or HIPAA. Ensure the tool or service preserves the integrity of digital evidence and complies with legal and regulatory requirements.

Automated data enrichment and analysis

To comprehensively understand the ongoing situation, security professionals must ensure the collected data is automatically correlated with other relevant information sources. Automated data enrichment and analysis save valuable time and enable security teams to discover hidden clues and patterns about the attack.

Best DFIR Tools

When an organization suffers a security breach, time is of the essence. Contacting a DFIR provider is necessary to guarantee that systems are restored as soon as possible and that the evidence required for attribution of an adversary is securely preserved. To help you prepare, this section explores the best DFIR solutions available now for your organization.
