The hidden threat within: Why internal investigations require expert eyes

While we diligently protect our networks from external hackers, a more insidious danger can sometimes originate from within our own organisations. Internal investigations have always been a part of running a business, but it is now becoming increasingly necessary to digitally investigate activity as part of cybersecurity strategy.

Benefits of forensic capabilities in IT

Having Digital Forensic (DF) abilities within an IT team can be highly beneficial for an organisation. DF teams complement IT teams by investigating security incidents, they help paint a detailed picture of what occurred and provide guidance on preventing similar incidents in the future. There are many more advanced benefits of having DF capability in organisations which we will be talking about in a minute but before that here are the challenges to consider:

• Resource allocation: Many organisations don’t have enough demand to justify a full-time DF team.
• Skills gap: There is significant shortage of cybersecurity professionals with DF skills. Even the specialised DF service providers feel the lack of the skilful professional on the DF employment market.
• Continuous learning: DF requires ongoing education to keep up with rapidly evolving technology and attack methods. IT teams would need to dedicate time for continuous learning to acquire knowledge which is difficult to maintain without frequent use.
• Jack of all trades: It is a common misconception that every IT member is equipped and trained to handle all aspects of cyber security including forensic investigation. There are always talented individuals within IT teams, but modern technology requires a team – nobody knows everything.

The need for specialised expertise

Forensic investigations demand a deep understanding of digital evidence, advanced tools, and meticulous methodologies. A skilled DF investigation team can uncover hidden clues; better understand tactics, techniques and procedures (TTPs); trace the source of a breach and identify potential perpetrators with precision by understanding ’digital footprints’ left behind by the attackers; contain, eradicate and remediate the incidents; and strengthen against future attacks.

Investigating trusted employees: A delicate task

One of the most challenging aspects of internal investigations is the suspicion of trusted employees. Accusing a colleague can be a sensitive matter, fraught with ethical and legal implications. It's essential to approach such investigations with the utmost care, ensuring that all evidence is gathered objectively and impartially.

CCL Solutions Group’s Incident Investigations team has significant experience with investigations relating to internal bad actors, including those in trusted positions, such as IT administrators and senior leadership. These investigations can be extremely sensitive, so it is important that the third party that you engage is trusted to follow communications protocols.

The benefits of a third-party investigation

Engaging a specialist organisation offers several key advantages:

• Objectivity and neutrality: An external provider offers an unbiased perspective, free from internal politics or conflicts of interest.
• Confidentiality and discretion: Protecting sensitive information and minimising disruption to your business will be their priorities
• Expertise and specialisation: You can call on skill sets and practical knowhow that may simply not be available in-house.
• Independence and credibility: Independent findings are likely to be viewed and accepted as impartial and trustworthy in legal proceedings.
• Expert witness experience: Look for providers who have a track record in expert witness services, including drafting court-ready expert reports and testifying in court. Should your case require legal action, this capability can be invaluable in presenting evidence and supporting your legal claims.
• Resource optimisation: Third parties can be engaged as needed, providing flexibility and cost effectiveness while allowing internal IT and security staff to focus on their core responsibilities.

A proactive approach to risk mitigation

By investing in a robust process, organisations can proactively and comprehensively address potential threats and minimise the damage caused by employee-led security breaches. Leaning on specialists in this field certainly helps take the pressure off, given the limitations of in-house IT teams and the criticality of protecting business assets and maintaining a strong security posture. Their hard-won expertise and experience will certainly make both of those imperatives easier for you.
