When one thinks of the most important elements of Digital Forensics and Incident Response, a few things might come to mind. Perhaps: instant response, swift containment and speedy return to business as usual. These are all critical parts of effective DFIR, however, true incident response engagements hinge on comprehensive analysis and systematic forensic investigation.
Digital forensics is fundamental to the response process as it helps uncover attacker footsteps. Ultimately, this allows you to understand an internal or external threat actor’s strategy, motives and target. It further assists in preserving the integrity of any evidence discovered, and will support your organisation in legal-proceedings.
The Content Security team has vast experience in the identification, collection, preservation, processing, review, analysis and presentation of evidence over a wide range of cases, including but not limited to:
This includes data breaches, malware outbreaks, internal frauds and system
misuse, cloud compromises, phishing, sexual harassment or other industrial relation disputes involving information systems.
Moreover, our services extend beyond just critical incident response. We specialise in Security Assurance Services, Governance, Risk and Compliance, and Enterprise Services, partnering with Strategic Vendors to protect your business.
With detailed reporting, expert guidance and recommendations as well as tailor-made IR plans, we help you bolster protection from future potential attacks. As a key element of our DFIR process, our forensic investigations help to:
Maintaining a Chain of Custody (CoC) is critical to evidence documentation as it ensures the integrity of the digital artefacts. This is key to presenting authentic evidence to a court of law and delineating who handled what systems, data and devices.
This involves processing the file system and memory for artefacts such as deleted, altered, hidden, encrypted or potentially malicious files and their metadata; communications via email, instant messaging or other methods; and OS and application logs stored on the system.
The entire digital forensics process is performed in order to gain a sense of clarity on what happened during an incident. Our expert investigator will determine the incident context based on creation, access, modification and deletion times.
All activities are documented and organised in order to form a timeline of events leading up to the security incident. This timeline provides the investigator and your team with a more complete understanding of how the incident could have occurred and how the malicious threat actor operated prior to the breach, malware outbreak etc.
From the contextualised evidence, we’re then able to derive more informed conclusions on attacker motives, strategies and targets. Above all, this helps you determine the nature of the malicious activity and the extent of the compromise. Furthermore, it shows you how to best remediate and protect your systems in the future.
As your trusted partner in all things cyber security, we are prepared to support you throughout the entire incident response process. With vast experience in DFIR, we understand that breaches and other security incidents extend beyond the recovery and post-incident handling stages. Thus, we’re able to act as Expert Witnesses to assist you in legal proceedings.
