Using Red Teaming to validate the performance of an outsourced managed service provider
Red teaming can provide assurance within a wide range of business scenarios. One interesting scenario we explored recently with a customer, a firm within the education sector, involved a situation where they had outsourced detection of security incidents to an external MSSP. As a result of a governance audit, our customer needed to determine whether the detective and corrective capabilities of the managed security services and associated internal technical controls functioned as expected across several lesser-seen compromise scenarios.

Future Work Expectations
Some industries have already migrated to a cloud centric view for daily operations, and this provides freedom for both the employer and the employees. Companies can now tap into global markets as geography no longer serves as a barrier and as mentioned in previous articles, ZeroTrust models continue to define how these remote identities are connected into the environment.

Cloud-Centric Models
Cloud environment management and setup can be very different from traditional internal/external based infrastructure deployment and therefore careful planning and design consideration is key to building scalable, resilient, secure cloud environments.

Identifying errors in cloud configurations that could lead to data breaches
Migrating from an on-premise paradigm to a cloud-based paradigm can be confusing and fraught with unconsidered risks. When you adopt cloud-based solutions – be they Platform as a Service, Software as a Service or Infrastructure as a Service – you will inevitably outsource much of the management and administration of the service to a cloud provider. Responsibilities that you previously held yourselves may now be the province of the cloud service provider rather than yourself. In this environment, you need to understand what your responsibilities are, and what you have delegated externally.

Let's Talk Quantum Cryptography Pt 2
When testing these types of systems, vulnerabilities can be broken down into two broad classes: Inherent flaws – These occur when an assumption made during the creation of a protocol doesn’t hold to be true, a new mathematical technique for example may break the security of the protocol. An example of a protocol with inherent flaws would be SSLv3. Implementation flaws – These occur because physical systems aren’t perfect, nor is our adaptation of theoretical principles to physical mediums. Where these imperfections exist so does the potential for exploitation. Today we’ll be looking at some implementation flaws, but to begin let’s have a think about the set-up Alice and Bob will need to carry out the steps of the BB84 protocol.

Shadow IT and Technical Debt: The Adversary's Allies
Shadow IT increases your business' security risks and is invisible to you. It might not be covered on your asset lists, because your asset management lists are incomplete. It might have no assigned owner, either because it doesn't fit neatly into any business unit, or isn't related to any current operational priorities but hasn't been fully decommissioned yet. It might have been installed outside of usual processes, either without authorisation or because usual processes were overridden.

Common TLS/SSL Issues And What They Mean
Whilst it may be tempting to support older protocol versions, such as TLS 1.0 or even SSLv3, to maximise compatibility with legacy systems, this does not come without serious security compromises. Older protocol implementations can have inherent weaknesses that undermine the security they offer. They can lack support for modern encryption algorithms used in more secure cipher suites and may be missing features implemented in later versions, specifically designed to mitigate against the shortcomings of the older protocol.

Cyberis Becomes CBEST Approved
Cyberis has announced that it is now an approved Penetration Testing provider under the Bank of England (BoE)'s CBEST scheme. CBEST is a framework run by the Bank of England through the industry body CREST that delivers controlled, bespoke, intelligence-led cyber security tests, to increase the resiliency of financial services organisations against cyber attacks. Regulators such as the Prudential Regulation Authority (PRA) and Financial Conduct Authority (FCA), have integrated the CBEST security assessment framework into their supervisory strategies.
