The prevalence of network attacks on today\u2019s enterprises has CIOs and CISOs researching a wide variety of ways to mitigate security risk. Well-publicized security tools such as Security Information and Event Management (SIEMs) and Data Loss Prevention (DLP) solutions can be beneficial, but don\u2019t forget about the foundational building blocks of your network security. It\u2019s vital to ensure that your organization\u2019s network is designed to keep customer and company data secure.\nIn the first of this two-part blog series, let\u2019s explore the elements that help create a strategy CIOs can use to build a layered, comprehensive approach to network security for their organizations.\nParallel Networking\nNetwork segmentation is a main ingredient in your network architecture. The best-case scenario is to prevent intruders from reaching your company\u2019s most valuable data, such as Point-of-Sale (POS) systems, in the first place. But traditional network segmentation is no longer the best strategy to protect this critical data.\nMany high-profile data breaches in recent years were pivot attacks, where hackers breached an easily accessible part of the network, then moved from there into an area where sensitive data was stored. If you currently have applications processing critical data, like POS or patient records, traditionally segmented on the same network as non-critical data, such as digital signage or the HVAC system, consider isolating these applications onto their own Parallel or \u201cair-gapped\u201d networks. This strategy keeps critical applications holding sensitive data physically separated from noncritical applications to help mitigate the risks of pivot attacks. \u00a0\nThreat Detection, not Just Intrusion Prevention\nPerhaps the most pressing need in network security is better detection. Most organizations focus on intrusion prevention but often bad actors access enterprise networks and are in the network for months before being detected. Consider the large network breaches that have recently been in the news. One thing stands out\u2014the intrusions were first reported by fraud systems, not by the companies that were breached.\nWhile it may have been said too many times, it\u2019s not a question of if your network will be threatened, but when. Because of this, many companies are working to develop an environment in which network attacks can be detected and responded to as quickly as possible.\nProactive efforts such as penetration testing are highly beneficial, but only if there\u2019s follow-up. If you're not ready to mitigate the breaches, what good is it to look for them? It\u2019s not enough to know your network has vulnerabilities. You have to dedicate the resources to fix what is broken. Threat detection needs to be top of mind for CIOs when planning or revamping a network security strategy.\nQuick Response & Employee Education\nA valuable component of network security in the enterprise is quick, easy access to your company\u2019s security team and continued employee education. Many branch locations don\u2019t employ onsite IT professionals; and employees at these sites don\u2019t usually receive extensive IT training. Providing basic knowledge of how to recognize phishing emails and malicious documents can help, especially when you provide easy access to the security team. The more swiftly a team member can notify the IT team at headquarters about inappropriate activity, the faster an attack can be thwarted before causing significant problems.\nRead more from Ryan Allphin next week with Part 2 \u201cBattle Network Security Threats with Preventative Practices and Education\u201d.
