What is Network Security?

Network security is a broad term that covers a multitude of technologies, devices and processes. In its simplest term, it is a set of rules and configurations designed to protect the integrity, confidentiality and accessibility of computer networks and data using both software and hardware technologies. Every organization, regardless of size, industry or infrastructure, requires a degree of network security solutions in place to protect it from the ever-growing landscape of cyber threats in the wild today.

Today’s network architecture is complex and is faced with a threat environment that is always changing and attackers that are always trying to find and exploit vulnerabilities. These vulnerabilities can exist in a broad number of areas, including devices, data, applications, users and locations. For this reason, there are many network security management tools and applications in use today that address individual threats and exploits and also regulatory non-compliance. When just a few minutes of downtime can cause widespread disruption and massive damage to an organization’s bottom line and reputation, it is essential that these protection measures are in place.

Why do we need Network Security?

Network security is important for home networks as well as in the business world. Most homes with high-speed internet connections have one or more wireless routers, which could be exploited if not properly secured. A solid network security system helps reduce the risk of data loss, theft and sabotage.

Unless it’s properly secured, any network is vulnerable to malicious use and accidental damage. Hackers, disgruntled employees, or poor security practices within the organization can leave private data exposed, including trade secrets and customers’ private details. Losing confidential research, for example, can potentially cost an organization millions of dollars by taking away competitive advantages it paid to gain. While hackers stealing customers’ details and selling them creates negative publicity and mistrust of the organization. The majority of common attacks against networks are designed to gain access to information, by spying on the communications and data of users, rather than to damage the network itself. But attackers can do more than steal data. They may be able to damage users’ devices or manipulate systems to gain physical access to facilities. This leaves the organization’s property and members at risk of harm.

Competent network security procedures keep data secure and block vulnerable systems from outside interference. This allows the network’s users to remain safe and focus on achieving the organization’s goals. More than that, it means that clients and partners can also interact with the organization confidently.
