Your guide to enterprise network security software

What is enterprise network security?

Enterprise network security is a broad term covering a range of technologies, devices, and processes. Some experts define it simply as a set of rules and configurations that protects the integrity, confidentiality, and accessibility of data in an enterprise network. Achieving this goal involves deploying software and hardware technologies to limit vulnerabilities and quickly respond when confronted by security issues.

The goal of any security system is to stop as many attacks as possible while being alert to and capable of responding quickly to breaches. Because of the inevitability of successful cyberattacks, many users give higher marks to products that allow them to respond promptly and effectively to attacks, even though another product may be better at stopping most attacks from happening.

The importance of robust enterprise network security

Firewalls are often the first line of defense, but network security hardly stops there. Access control, threat intelligence, intrusion detection and prevention, data loss prevention, email security, endpoint security, and patch management all play a role in protecting the network and its data.

Because advanced persistent threats and insider threats are the most significant danger to corporate secrets, behavioral analytics – studying user behavior for signs of an active intruder – has become a critical component of network security.

Tying all that together are products like security information and event management (SIEM) systems, bringing all security and log data into a centralized console for easier detection and response.

Complete and total IT security isn’t possible. Hence, organizations need to mix and match those security technologies and provide the optimal security level for their organization within cost constraints. With the average cost of a data breach approaching $4 million according to IBM, any security solution will pay for itself and avert trouble.

Managing Personnel Fatigue

The complexity of both corporate systems and the attacks against them can make it hard to sort legitimate security events from ordinary activities. IT security personnel can get overwhelmed if they lack the necessary tools to make sense of the data. Solutions that can identify and prioritize the most critical threats while reducing false positives are essential for reducing stress on security staff.

Scaling To Network Size

Unlike the monolithic corporate computer systems of the past, most enterprise IT environments today consist of large, interconnected systems, servers, and mainframes supporting thousands of individual devices often connected via multiple wired and wireless networks.

From the mainframes to the individual devices, every single node presents a potential point of attack. As a result, the larger your system, the more surface area it exposes to hackers who can use its complexity to conceal intrusions, exploit potential backdoors, and remain undetected in the infrastructure.
