Cisco communications product security hardening updates: check versions before planning upgrades

Facts

On 21 October, Cisco announced security hardening updates for several communications products, including Unified Communications Manager and Unity Connection. The advisory sets out fixed-version arrangements for 15SU5 and requires affected 14-series deployments to migrate to a fixed version. Cisco said it was not aware of related malicious exploitation at publication.

Analysis

Telephone and collaboration systems also belong in the patching plan. This is an official update notice; it does not establish that any organisation using the product has been compromised. Check your product, version and compatibility before upgrading.

Suggested Actions

• Use the product tables in the official advisory to check affected versions and upgrade paths, and confirm applicable options with your maintenance provider.
• Back up settings and schedule a maintenance window. After updating, test calls, voicemail and related integrations.

Veeam launches a sovereign service provider programme: examine actual control when choosing backups

Facts

On 20 October, Veeam announced the phased rollout of its global Sovereign Service Providers Program, starting with the VCSP Data Sovereignty Competency. The announcement also states that the programme does not replace customers' own legal, regulatory, risk and compliance assessments.

Analysis

When choosing backup services, ask not only where data is stored but who can access it, how to retrieve it and how to migrate if the service ends. A vendor programme can be a starting point for enquiries, but is not independent security certification or a guarantee of suitability for every business.

Suggested Actions

• Ask the supplier to specify data locations, administrative permissions, subcontracting arrangements and export methods in writing.
• Practise recovery using your own data volumes, and confirm the retrieval and deletion process when leaving the service.

Microsoft proposes continuous oversight of AI agents: organisations should first define permissions clearly

Facts

On 19 October, Microsoft introduced Project Perception, outlining AI agent management through identity, permissions, execution environments and continuous oversight, and discussing the role of Guardian Agents. This is a vendor's security direction and technical introduction, not an independent effectiveness test.

Analysis

When AI can operate on files or systems, its permissions should be managed like an organisational account. Decide separately what it can do and what it is allowed to do, so that one mistaken action does not affect more data.

Suggested Actions

• List each AI agent's owner, identity, available tools and accessible data.
• Restrict actions such as deletion, external transmission and permission changes. Retain activity logs and test how to stop execution and revoke authorisation.
