Cyberthreats are constant – your security should be too

Continuous Security Monitoring (CSM) is the most effective response yet to the changing nature and frequency of cybersecurity threats. Not knowing when a threat will materialise, or what its source will be, has meant that increasing numbers of organisations are now opting for constant surveillance. CSM is far more than the firewalls, anti-virus checkers and email monitors that most organisations already have. It combines aspects of audit and risk assessment with enhanced security to employ surveillance where it really matters.

To implement a CSM system, the organisation first has to audit its systems and assess them for business criticality. As most section managers consider their own systems to be the most critical, an independent report is probably the most objective way to do this.

Risk assessment routines can then be used to quantify the business damage that would result from a particular system or infrastructure component being attacked and compromised. Those systems that have the ability to damage the business can then be placed under continuous surveillance. 


Identifying attack potential

Whether the system and its data are on-premise, at a remote site or in the cloud, CSM systems will detect any unauthorised device attempting to connect to the network, along with numerous other potential attack events. The system will issue an immediate alert and take action to ward off the threat and prevent damage. The CSM can provide a real-time picture of an entire system, or its most critical components, as required. 


Controlling changes

The business also benefits from a tightly controlled change environment. Planned changes are carefully tracked to ensure they don’t leave any system vulnerabilities and an unplanned change triggers an alarm. 

And let’s not forget that attacks aren’t always external events. The best CSM systems give you protection from “privileged insider” attacks too.
