Network security is essential for all networks–whether it is a simple network used by a small business that serves a local community or a gargantuan network used by a third-party logistics firm that serves multinational companies. Although, this is a big, complex theme, which this makes it almost impossible to fully grasp, it is possible to get an overview of what it is, how it works, and why it is integral to the success of any enterprise. One way to do this is by reviewing a selection of frequently asked questions.
Here, then, are 9 questions about network security that you may have always wanted to know but may have been too afraid to ask:
1.What Is Network Security?
Network security is any activity that has been designed to secure a network. When analyzing the security features of a network, network administrators focus on the integrity, reliability, and usability of a network. Flaws in any of these three key functions of a network could leave it vulnerable to threats coming into the network and spreading through it. As Trend Micro suggests, the most efficient network security measures can be deployed in real time so that threats don’t get the chance to really “dig in.”
2. What are the common threats to a network?
Networks must stop a large number of bots and botnets coming in from the Internet or neutralize those that have already infiltrated the network. These threats include Trojan horses, worms, viruses, adware, and spyware. Networks must also guard against a variety of attacks like denial of service attacks, hacker attacks, and zero-day attacks. Finally, networks must also guard against data theft—for example, loss of sensitive personal information about employee or customer information that might lead to identity theft.
3. What has to be done to secure a network?
There is no single solution to protecting a network. Instead, multiple levels of security are often used to protect a network and its resources. Sometimes this might be redundant, but at other times, an attack that gets past one layer of defense is stopped by another level of protection.
Network security is a combination of hardware and software features. Additionally, the software has to be frequently updated–since viruses are constantly mutating into either more resistant strains or entirely new ones and malicious hackers are constantly coming up with new threats to breach established defenses.
4. What are the components of network security?
There are a large number of components used to protect a network like anti-virus software, anti-spyware software, firewall software, intrusion prevention systems (IPS), and Virtual Private Networks (VPNs).
5. Why should a business protect its network?
A company with network security will protect against disruption to their business, comply with mandatory regulations, protect employee data, safeguard customer information, and reduce the risk of legal liability in the event of data loss or theft.
6. Does network security impact business revenue?
A company with a secure network will win employee loyalty, partner collaboration, and customer trust—all factors that improve the bottom line.
7. Can a reliable network improve employee productivity?
A strong network will allow employees to access the office network from home or when they are on the road without the fear of introducing threats to it from their computing or mobile devices across the Internet. This, of course, leads to improved productivity.
8. How can a good network save costs?
A poorly maintained network can be expensive because it results in costs associated with service disruption and repair. In contrast, a network with strong security can save costs related to little to no network downtime. An effective network can also allow new applications and services to be added without compromising network performance.
9. How can a company improve the security of its network?
Before a company can improve its network security it has to get a clear network risk assessment. It can do this by noting what features it currently has like anti-spyware software, antivirus software, and firewall protection; what its digital assets are like email subscriber lists, etc; and how it is sharing information both inside and outside the company.
Network security is essential to the success and profitability of any business. Sometimes it is neglected because it is a complex technical feature of a company’s operations and executives are not clear what it is and why it matters.
