What is enterprise network security? <\/span><\/p>\n

Businesses can\u2019t ignore this cybersecurity question or all the implications it carries. Network security threats prove difficult to detect or prevent; moreover, recovering data compromised by a digital security threat creates pressing challenges IT security teams can\u2019t handle alone.<\/span><\/p>\n

\t\t\t

<\/a><\/p>\n<\/div>\n\t\t<\/div><\/div>\n

We offer a deep dive into this critical aspect of enterprise-level cybersecurity, including its key challenges and capabilities. <\/span><\/p>\n

What is Enterprise Network Security? <\/b><\/h2>\n

Network security and <\/span>SIEM<\/span><\/a> relate to each other, although how they relate remains a subjective observation. Some could argue network security serves as SIEM\u2019s ultimate goal; others contend SIEM serves as a capability in a larger enterprise network security policy. \u00a0\u00a0\u00a0<\/span><\/p>\n

At its core, enterprise network security offers a strategic approach to digital security; it secures data and digital assets on computer network infrastructures against any number of cyber attacks or unauthorized access. <\/span><\/p>\n

If we perceive enterprise network as its own kind of solution, then in addition to <\/span>SIEM<\/span><\/a> other key capabilities include anti-malware, data loss prevention, intrusion detection and response, behavioral analytics, and email security. <\/span><\/p>\n

Common Enterprise Network Security Issues <\/b><\/h2>\n

Every cybersecurity solution comes with its own issues and challenges; the ideal \u201cset-it-and-forget-it solution\u201d doesn\u2019t exist with current technologies. Thankfully, no challenge in cybersecurity proves insurmountable with the right level of awareness and preparation. <\/span><\/p>\n

Here are a few of the largest problems facing enterprise network security <\/span><\/p>\n

Dealing with Multiple Systems<\/b><\/h3>\n

Enterprise IT environments consist of related and connected systems, mainframes, and devices operating across multiple wireless networks. The larger the system, the more places hackers can use to conceal their attacks, exploit other backdoors, and dwell on the infrastructure. <\/span><\/p>\n

Ultimately, this problem with business-level network security reflects the larger problem with cybersecurity visibility. As a rule, you can\u2019t protect what remains unseen. A SIEM solution can help improve visibility by collecting log data from across the entire network and uncovering previously unseen network areas. \u00a0\u00a0<\/span><\/p>\n

Patch Management <\/b><\/h3>\n

While visibility is key to cybersecurity policy success, patch management may be the key to cybersecurity solution success; this proves especially true for network security and SIEM. <\/span><\/p>\n

Often enterprises become turned off to the deployment requirements of SIEM and other cybersecurity solutions and fail to invest more time and resources into their maintenance. However, without this maintenance hackers can circumvent their capabilities far more easily. <\/span><\/p>\n

Cybersecurity patches usually contain critical threat intelligence enabling solutions to keep up with evolving cyber attacks. Additionally, patches help prevent any discovered security holes in solutions before hackers can exploit them. <\/span><\/p>\n

Your enterprise network security and SIEM solutions should assist your IT security team with patch management capabilities to help prevent these issues. <\/span><\/p>\n

Alert Fatigue<\/b><\/h3>\n

Drawing information from across the entire IT environment can create contradictory statements and misunderstood security events. SIEM and network security at the enterprise level must follow your security team\u2019s correlation rules to determine what constitutes a noteworthy security event. <\/span><\/p>\n

Sometimes, misconfigured SIEM results in security teams becoming overwhelmed with security alerts pointing to perfectly ordinary activities as security events; the struggle becomes investing so much time and research into investigating each false alarm on the off-chance it points to a legitimate threat. <\/span><\/p>\n

Therefore, your enterprise network security solution must offer contextualization for each threat to help IT security teams determine which alerts require follow-up investigation. <\/span><\/p>\n

Additionally, your IT security teams must constantly monitor and evaluate your correlation rules; these rules should correspond to your normal business process to establish an accurate behavioral baseline. If you don\u2019t, then your legitimate activities could surpass the machines baseline and trigger an alert. \u00a0<\/span><\/p>\n

Key Enterprise Network Security Capabilities<\/b><\/h2>\n

As outlined above, enterprise network security straddles the line between endpoint security and SIEM; indeed, some consider <\/span>SIEM<\/span><\/a> a capability within the enterprise network security umbrella. However, you may find it beneficial to think of business-level network security as a subfield or a goal of SIEM solutions for clarity.<\/span><\/p>\n

Of course, listing all of the relevant business-level network security capabilities in detail would require an article several pages. Instead, we isolate the top three capabilities you should consider:<\/span><\/p>\n

Behavioral Analytics <\/b>\u00a0\u00a0<\/span><\/h3>\n

Trying to monitor all employees and users across your entire IT environment is a Sisyphean task. Instead, IT security teams can establish baseline \u201cnormal\u201d behaviors for each user and closely monitor employees who display behaviors outside their individual baseline. <\/span><\/p>\n

Behaviors that should trigger an enterprise network security alert include:<\/span><\/p>\n
