<p>In today’s vast digital landscape, most data files continue to exist in a legacy environment which makes them vulnerable to bad actors and other potential security flaws. <a href="https://smartledger.solutions/" target="_blank" rel="noopener nofollow">SmartLedger</a> is dedicated to solving these and other problems through its custom-made blockchain solutions.</p>



<p>SmartLedger <a href="https://sentinelnode.online/" target="_blank" rel="noopener nofollow">developed the Certihash suite</a> specifically for enterprise clients, offering them a solution to mitigate the risks of data breaches. The <a href="https://www.bitcoinsv.com/certihash-and-ibm-to-deploy-sentinel-node-cybersecurity-tool-on-bsv" target="_blank" rel="noopener">initial module released within Certihash is Sentinel Node</a>, which provides real-time event notifications for network activities. This comprehensive toolset leverages the BSV blockchain to ensure records&#8217; confidentiality, integrity, and availability, making them publicly accessible on a permissionless blockchain.</p>



<h2 class="wp-block-heading" id="h-what-is-sentinel-node">What is Sentinel Node?</h2>



<p>Certihash’s Sentinel Node is a next-generation <a href="https://www.bsvblockchain.org/news/cyberattacks-business-impact-how-sentinel-node-contains-and-combats-threats-in-cybersecurity" target="_blank" rel="noopener">cybersecurity detection assurance tool</a> which provides instant file integrity and change monitoring of network anomalies and events, mitigating the overall time to identify a data breach.</p>



<p>It does this by utilising the BSV blockchain to limit the need to transfer sensitive log data to a third party, allowing for exponentially faster detection and alert times.</p>



<p><a href="https://www.bsvblockchain.org/news/certihash-is-the-perfect-match-between-blockchain-and-cybersecurity" target="_blank" rel="noopener">Sentinel Node</a> creates a chain of hashes for each file entry, protecting the data integrity of all data on the network. These hashes are placed on the public blockchain ledger, ensuring transparency and security.</p>



<p>When a cybercriminal attempts to cover their tracks, Sentinel Node will discover the hash break immediately and alert the system administrator.</p>

<p>While most Security Information and Event Management (SIEM) tools claim to provide <a href="https://www.bsvblockchain.org/news/detecting-network-breaches-instantly-with-certihash-and-bsv" target="_blank" rel="noopener">‘real-time’ detection</a>, in reality, most have a window of more than two hours between log capture transfer, analysis and alerting.&nbsp;By comparison, SmartLedger estimates that Sentinel Node is:</p>



<ul>
<li>x720 times faster at critical log detection;</li>



<li>x1.400 times faster at advanced log detection;</li>



<li>x4,032 times faster at standard log detection.</li>
</ul>



<p>Other benefits of Sentinel Node include:</p>



<ul>
<li>Sensitive data always stays in-house;</li>



<li>Faster file integrity monitoring;</li>



<li>Instant alert upon change detection;</li>



<li>Permanent attestation of alert records;</li>



<li>Data is recorded in perpetuity;</li>



<li>It provides actionable cybersecurity intelligence.</li>
</ul>
