Security Clearances in the public domain - Staying Vigilant

Recent reports in national press highlight warnings from the Five Eyes intelligence alliance regarding hostile-state actors using professional networking platforms should serve as an important reminder to anyone working across Government, Defence, National Security and Critical National Infrastructure.

LinkedIn is a great platform for professional networking, career development and connecting with trusted suppliers and employers. However, individuals holding security clearances or working on sensitive programmes should remain mindful that not every connection request, job opportunity or research enquiry is necessarily what it appears to be.

What many people may not realise is that UK Government guidance explicitly states that security-cleared personnel must not to disclose their level of security clearance on social media profiles or public online platforms, such as Linked In.

Whilst it remains common to see references such as:

❌ SC Cleared ❌ DV Cleared ❌ eDV Cleared

on public profiles, UK Security Vetting policy states that clearance holders do not publicly advertise their clearance level online.

The reason is simple

A hostile actor does not need access to classified information to build an intelligence picture. Seemingly harmless details can be combined to create a valuable profile, including:

• Security clearance level
• Current employer or client
• Programme or project information
• Technology specialisms
• Location information
• Professional networks and connections

Individually, these details may appear insignificant. Collectively, they can provide valuable insight into organisations, programmes and individuals operating within sensitive environments.

For those working within Defence, Government and National Security, good operational security extends beyond the workplace and into our digital footprint.

A few simple precautions can make a significant difference:

• Verify the identity and legitimacy of organisations making contact
• Be cautious of unsolicited approaches offering unusually attractive opportunities
• Avoid discussing sensitive projects, programmes or customer information online
• Review the information published on social media and professional networking profiles
• Work with organisations you know, trust and can verify

So does protecting yourself, your employer, your clients and the programmes you support.

In an increasingly connected world, a good rule of thumb remains:

If in doubt, verify who you’re speaking to before you engage.
