Layered protection for IT security essentially looks at how one protects themselves from threats through sequential layers. Also referred to as Layered Security, it is a way of having multiple levels of protocols that protect data from potential loss. Having more than one protective layer improves the IT resiliency against outages and therefore helps the individual or business to continue operations without incurring loss of income due to downtime.
Likened to swiss cheese slices arranged side by side to each other, security layers mitigate the attempt of a breach in each defensive layer, lowering the risk of a breach or loss. Therefore having ‘holes’ in one defense, won’t result in a breach as other defensive layers are present to mitigate the attack.
Layered Protection is a highly efficient and comprehensive security service provided by vendors that employs layered microservices to sequentially filter away threats. They include advanced threat signatures, behavioural and heuristic analysis, static code analysis and sandboxing. This allows signature-based threats to be filtered out early during the first layers. Subsequent layers will detect more advanced threats so that the final layer that uses higher resource-intensive analysis just needs to process a small amount of traffic that looks suspicious to the system.
Companies such as Barracuda, are well equipped with the technological expertise to assist businesses through their Barracuda Advanced Threat Protection. Attacks aimed at the many vectors by which attackers gain access to a network or infrastructure to deploy an attack such as through emails, the network perimeter, the user, remote access, web applications and remote users or mobile devices, can be thwarted.
Incorporating a well-built protective layered approach, that is a comprehensive approach to detect both known and unknown threats, is a must in todays highly volatile and ever growing cybercrime world. These policies leverage real-time threat intelligence by addressing all threat vectors and all platform types to factor workloads migrating from physical, to virtual, to cloud. This gives the business the protection it needs to conduct their dealings whether it is on premise, on cloud or on mobile without worry of losing their data. For more information, click here.
